A Middle-Aged Woman With Hematochezia, Hypotension, and Leg Cramps.

CASE PRESENTATION: A 57-year-old woman with a history of mantle cell lymphoma presented to the ED with complaints of vomiting, bleeding per rectum, and leg cramps, that started 6 h prior to her arrival. She had received chemotherapy a week prior. Her leg cramps were not associated with pain or swelling of the legs; she also denied any trauma to the legs. She did complain of mild lower abdominal pain at presentation. Review of systems was negative for fever, chills, diarrhea, chest pain, and dizziness. She denied using alcohol or nonsteroidal anti-inflammatory drugs. The patient was tachycardic with a systolic BP (SBP) of 85 mm Hg and was administered 1-L normal saline, with improvement in her SBP to 90 mm Hg. The hematocrit level was 24%, the WBC count was 0.3 × 109/L, and the platelet count was 6 × 109/L in the ED. On arrival in the ICU, she was noted to have an SBP of 70 mm Hg. Resuscitation with IV fluids was initiated, followed by transfusion of packed RBCs and platelets, based on the blood counts. Despite aggressive fluid resuscitation and improvement in her hemoglobin, the patient remained persistently hypotensive. The diagnosis of underlying septic shock because of neutropenia was considered; the patient was started on vasopressors and empirical broad-spectrum antibiotics, with improvement in her BP. After this, the patient was sent to radiology for a CT scan of the abdomen and pelvis with contrast to evaluate for mesenteric infarction, enteric or colonic bleeding, and the need for arterial embolization.

Health-Related Quality of Life Is Decreased After Necrotizing Soft-Tissue Infections.

BACKGROUND: A necrotizing soft-tissue infection (NSTI) is a rare but severe infection with a high mortality rate of 12%-20%. Diagnosing is challenging and often delayed. Treatment consists of surgical debridement of all necrotic tissue and administration of antibiotics. Despite adequate treatment, survivors are often left with extensive wounds, resulting in mutilating scars and functional deficits. Both the disease and the subsequent scars can negatively influence the health-related quality of life (HRQoL). The present study was performed to contribute to the knowledge about HRQoL in patients after NSTI. METHODS: We retrospectively identified patients treated for NSTI in a tertiary center in the Netherlands. Patient and treatment characteristics were collected and patients were asked to fill in a Short Form 36 questionnaire. RESULTS: Forty-six patients with a diagnosis of NSTI were identified. Twenty-eight (61%) were male and mean age was 57 y. Thirty-nine patients (80%) survived. Thirty-one (84%) of the survivors returned the questionnaire after a median follow-up of 4.1 y (interquartile range [IQR], 2.4-5.9 y). Statistically significantly decreased scores when compared to the Dutch reference values were observed for the Short Form 36 domains, physical functioning, role-physical functioning, general health, and the combined Physical Component Score. No differences were observed for the other five domains or for the Mental Component Score. CONCLUSIONS: This study confirms that NSTI negatively affects HRQoL as reported by the patient, especially on the physical domains. To learn more about HRQoL in patients after NSTI, studies in larger groups with a more disease-specific questionnaire should be performed. LEVEL OF EVIDENCE: Level 3, prognostic and epidemiological.

Pneumorachis from the cervical to the sacral spinal canal with spinal epidural abscess by gas gangrene.

We present a 70-year-old woman with severe diabetes mellitus, who experienced low back pain and left lower leg paralysis. Computed tomography showed air in the spinal canal from C4 to S5, and magnetic resonance imaging revealed an epidural abscess from Th11 to L1. Laboratory findings showed increases in inflammatory indicators and blood culture indicated the presence of Escherichia coli. The patient was treated conservatively with antibiotics. Neurological deficits and inflammatory data improved during the course. Follow-up imaging studies showed the disappearance of gas and epidural abscess. The existence of air in the spinal canal is a rare condition known as pneumorachis. To the best of our knowledge, such a long pneumorachis ranging from the cervical to the sacral spinal canal with epidural abscess caused by gas gangrene has not yet been described. We should therefore realize the possibility of epidural abscess produced by gas gangrene and treat it appropriately.

Sudden death due to gas gangrene caused by Clostridium septicum in goats.

BACKGROUND: Even though gas gangrene caused by Clostridium septicum in goats is mentioned in the classical textbooks, we have not managed to find any case description in the literature. CASE PRESENTATION: Clinical signs resembling gas gangrene such as subcutaneous bloating, edema and crepitation were detected at various body parts of nine pregnant animals at the ages of 2-3 years on a hair goat farm (n = 170) located in Bingol province, Eastern Turkey. Five of these suspected animals with severe clinical symptoms died within 2 days. Various samples such as internal organs, edematous skin and edema fluid collected from dead and live animals were analyzed for the presence of clostridial agents by histopathological and microbiological methods. As a result of macroscopic and microscopic examination, lesions of gas gangrene were detected. The suspected isolates were identified and confirmed as C. septicum by bacteriological and molecular methods. CONCLUSION: The present study was the first to report identification of C. septicum as primary agent in the gas gangrene of goats.

Presence of periaortic gas in Clostridium septicum-infected aortic aneurysm aids in early diagnosis: a case report and systematic review of the literature.

BACKGROUND: Clostridium septicum-infected aortic aneurysm is a fatal and rare disease. We present a fatal case of C. septicum-infected aortic aneurysm and a pertinent literature review with treatment suggestions for reducing mortality rates. CASE PRESENTATION: A 58-year-old Japanese man with an unremarkable medical history presented with a 3-day history of mild weakness in both legs, and experienced paraplegia and paresthesia a day before admission. Upon recognition of signs of an abdominal aortic aneurysm and paraplegia, we suspected an occluded Adamkiewicz artery and performed a contrast-enhanced computed tomography scan, which revealed an aortic aneurysm with periaortic gas extending from his chest to his abdomen and both kidneys. Antibiotics were initiated followed by emergency surgery for source control of the infection. However, owing to his poor condition and septic shock, aortic repair was not possible. We performed bilateral nephrectomy as a possible source control, after which we initiated mechanical ventilation, continuous hemodialysis, and hemoperfusion. A culture of the samples taken from the infected region and four consecutive blood cultures yielded C. septicum. His condition gradually improved postoperatively; however, on postoperative day 10, massive hemorrhage due to aortic rupture resulted in his death. CONCLUSIONS: In this patient, C. septicum was thought to have entered his blood through a gastrointestinal tumor, infected the aorta, and spread to his kidneys. However, we were uncertain whether there was an associated malignancy. A literature review of C. septicum-related aneurysms revealed the following: 6-month mortality, 79.5%; periaortic gas present in 92.6% of cases; no standard operative procedure and no guidelines for antimicrobial administration established; and C. septicum was associated with cancer in 82.5% of cases. Thus, we advocate for early diagnosis via the identification of periaortic gas, as an aortic aneurysm progresses rapidly. To reduce the risk of reinfection as well as infection of other sites, there is the need for concurrent surgical management of the aneurysm and any associated malignancy. We recommend debridement of the infectious focus and in situ vascular graft with omental coverage. Postoperatively, orally administered antibiotics must be continued indefinitely (chronic suppression therapy). We believe that these treatments will decrease mortality due to C. septicum-infected aortic aneurysms.

Infección mortal por Clostridium perfringens con hemólisis tras quimioterapia en un adolescente / A fatal Clostridium perfringens infection with hemolysis after chemotherapy in an adolescent

Vertebral osteomyelitis and epidural abscess caused by gas gangrene presenting with complete paraplegia: a case report.

INTRODUCTION: Gas gangrene is most often caused by Clostridium perfringens infection. Gas gangrene is a medical emergency that develops suddenly. The mortality rate is higher with trunk involvement than with involvement of the extremities, which carries a better prognosis. With respect to vertebral involvement, there are few reports in the literature. The purpose of this paper is to report a very rare case of vertebral osteomyelitis caused by gas gangrene. CASE PRESENTATION: A 78-year-old Japanese woman with diabetes mellitus was admitted to our hospital with the chief complaints of back pain, dysuria, and complete paralysis of both legs. A computed tomography scan showed soft tissue swelling anterolaterally at intervertebral disc level T11/12 and a gas-containing epidural abscess that compressed her spinal cord. Cultures later grew Clostridium perfringens and Escherichia coli. Hemilaminectomy was done from T10 to T12, and an epidural abscess was removed. She went on to have fusion surgery 6 weeks after the initial operation and subsequently experienced complete pain relief. She was discharged 2 months later, at which time she was able to walk with a cane. Examination 18 months after surgery showed normal gait without a cane. CONCLUSIONS: Discitis caused by gas gangrene infection was successfully treated by immediate debridement and subsequent fusion surgery.

Infecção fulminante por Clostridium septicum: relato de caso / Fulminant Clostridium septicum infection: case report

As infecções de tecidos moles causadas por espécies de Clostridium têm sido descritos na literatura por centenas de anos. A gangrena gasosa por Clostridium continua sendo uma importante causa de morbidade e mortalidade no mundo. O objetivo deste estudo foi relatar um caso de paciente com diagnóstico de síndrome mielodisplásica, submetida à curetagem uterina e evoluindo com gangrena gasosa espontânea, 10 horas após a cirurgia.Paciente do sexo feminino, 26 anos, com história de dor em terço distal de membros inferiores, irradiando para região de fossa poplítea, com piora à palpação e movimentação dos membros, acompanhada de aumento da temperatura e volume local. Negava febre, hiperemia ou trauma local, evoluindo para choque séptico. Angiotomografia das extremidades e pelve revelou a presença de gás permeando os feixes musculares da coxa e da perna, bilateralmente. A combinação da história e exame clínico,ao estudo radiológico confirmou o diagnóstico sindrômico de gangrena gasosa espontânea. Apesar de elevado índice de suspeição melhorar os resultados clínicos, tais infecções progridem tão rapidamente que o óbito pode preceder o diagnóstico,não obstante, o reconhecimento precoce e tratamento agressivo,incluindo drenagem aberta ou percutânea. Antibióticos parenterais contra Clostrídios devem ser prontamente iniciados, bem como medidas de suporte clínico.

The soft tissue infections caused by Clostridium species have been described in the literature for hundreds of years. The gas gangrene due to Clostridium remains an important cause of morbidity and mortality worldwide. The aim of this study was to report a patient diagnosed with myelodysplastic syndrome who underwent curettage, evolving with spontaneous gas gangrene, 10 hours after surgery. Female patient, 26 years, with pain in the distal third of the lower limbs, radiating to the popliteal fossa region, which worsened on palpation and movement of limbs, and accompanied by an increase in temperature and local volume. She denied fever, redness or local trauma, and progressed to septic shock. Angiotomography of the extremities and pelvis revealed the presence of gas permeating the muscle bundles of the thigh and leg bilaterally. The combination of history and clinical examination and radiological examination confirmed the syndromic diagnosis of Spontaneous Gas Gangrene. Although a high index of suspicion may improve clinical outcomes, such infections progress so rapidly that death usually precedes the diagnosis. However, early recognition and aggressive treatment, including open or percutaneous drainage and parenteral antibiotics against Clostridia should be promptly initiated, along with clinical support.

Medical cause of compartment syndrome: a fatal case of Clostridium septicum.

A 57-year-old woman with non-Hodgkin's lymphoma presented to the emergency department with febrile neutropaenia. She complained of fever and malaise and had a normal physical examination. Ten hours later, she developed worsening right leg pain that required escalating doses of morphine. Her physical examination remained unremarkable. Owing to the increasing pain in her leg, an x-ray was performed which revealed subcutaneous emphysema. She subsequently developed numbness over her right leg and, then, 21 h after admission the leg became cold and ischaemic. Haemorrhagic bullae and bruising began to form and crepitus was palpated. She was taken to the operating room where debridement was attempted, but the surgeons found deep and extensive tissue necrosis. She was transferred to the intensive care unit for a trial of medical therapy and eventual palliation. The pathology revealed severe myonecrosis secondary to Clostridium septicum. She expired 36 h after presentation.

Spontaneous uterine perforation due to clostridial gas gangrene associated with endometrial carcinoma.

Few cases of clostridial gas gangrene associated with uterine malignancy have been reported. We report on a 46-year-old woman with clostridial sepsis. On the day of admission due to severe abdominal pain, peritonitis was diagnosed, and computed tomography showed free air in the abdomen. At emergency laparotomy, perforation of the necrotic uterine wall was observed. During hysterectomy, septic shock developed, and life-saving therapy was performed in the intensive care unit after surgery. Pathological examination of the necrotic uterine wall showed grade III endometrial adenocarcinoma of the uterine endometrium (International Federation of Gynecology and Obstetrics stage IIIa) with gas gangrene due to Clostridium perfringens. This report aims to alert gynecologists to the possibility that clostridial gas gangrene of the uterus can occur in patients with peritonitis and intra-abdominal free air. Early recognition and aggressive therapy can save patients' lives.

Spontaneous intrahepatic gas gangrene and fatal septic shock.

Gas gangrene of the liver is a rare clinical syndrome associated with a high rate of mortality. It is mostly associated with malignancy and immunosuppression. We report on a male patient who presented at the department of emergency medicine with high fever but no localised complaints. CT scan revealed a cavitary lesion filled with air in the liver. Clostridium perfringens was proved to be present in the hepatic lesion and the blood, and clostridium perfringens sepsis with gas gangrene of the liver was diagnosed. Despite early diagnosis and treatment the patient died. The importance of "an aggressive treatment policy" in this kind of life-threatening disease is emphasised.

Fatal Morganella morganii bacteraemia in a diabetic patient with gas gangrene.

We report a case of a 60-year-old lady with a history of a heel ulcer that had not responded to antibiotic therapy. This progressed to involve the right leg, which was swollen and erythematous. Radiological imaging revealed the presence of gas within the fascial planes. Blood cultures on admission yielded Morganella morganii. Due to the extent of the gas gangrene and her co-morbidities the patient was not suitable for surgical intervention and was treated conservatively with antibiotics. She deteriorated and died within 72 h of presentation. Non-clostridial gas gangrene is relatively rare, and diagnosis is frequently delayed and often missed. Early aggressive surgical intervention combined with appropriate antibiotic therapy is essential. Bacterial species other than Clostridium should be considered in all cases of gas gangrene.

Successful management of spontaneous Clostridium septicum myonecrosis.

Spontaneous Clostridium septicum myonecrosis, or gas gangrene, is an extremely rare soft tissue infection associated with malignancy and immunosuppression. Even with appropriate treatment the mortality rate approaches 100%. We present the case of a patient who presented with fulminant Clostridium septicum sepsis and myonecrosis who was successfully treated and made a full recovery within two weeks of the initial episode.

Emergency thyroidectomy in infected thyroid cyst due to spontaneous gas forming organisms.

We are reporting a case of a young female, who presented to emergency room with sudden increase in thyroid swelling, high fever and acute respiratory distress. Clinical diagnosis of spontaneous infection of thyroid cyst was made. Operative finding was infection of thyroid cyst with gas formation. Systemic antibiotics and operative intervention by subtotal thyroidectomy led to recovery of the patient.

Fatal myelotoxicity after azathioprine treatment.

Azathioprine and 6-mercaptopurine have been used for many years in the treatment of inflammatory bowel disease. Approximately 0.3% of the population are homozygous for variant alleles associated with extremely low thiopurine S-methyltransferase enzyme activity. We describe the case of a young patient with ulcerative colitis, homozygous for TPMT*3A alleles, who suffered fatal azathioprine-induced myelotoxicity after standard dosing with azathioprine. Screening for decreased activity of TPMT in patients prior to azathioprine treatment is advised to minimize the risk of drug-induced toxicity.
