From January 1986 through February 1993, there were 16 episodes of respiratory infection due to Corynebacterium pseudodiphtheriticum in 13 patients. The ages of patients ranged from 24 to 77 years; the ratio of male to female patients was 3:1. One patient had three episodes of infection, and another patient had two. In one patient, who died of disseminated intravascular coagulation, the level of IgG was low. One patient was receiving prednisolone when the infection occurred. In two cases a mixed infection with Streptococcus pneumoniae was noted. Sputum cultures yielded C. pseudodiphtheriticum (> or = 10(7) cfu/mL). An increased neutrophil response in the sputum of infected patients was observed. Gram staining and electron microscopy of sputum showed phagocytosis of C. pseudodiphtheriticum by the neutrophils. ELISAs also showed an increase in the level of immunoglobulin against C. pseudodiphtheriticum after infection. Tests for determination of MICs of antibiotics revealed that C. pseudodiphtheriticum isolates were susceptible to ampicillin, amoxycillin/clavulanic acid, cefazolin, cefuroxime, ceftazidime, and imipenem. All strains were resistant to nalidixic acid; borderline susceptibility to ofloxacin, norfloxacin, and ciprofloxacin was noted. We suggest the use of beta-lactam antibiotics in the treatment of infection with C. pseudodiphtheriticum.

Two cases of Gross E-type tracheoesophageal fistulae associated with interruption of the aortic arch in one and coarctation of the aorta in the other in early infancy were treated radically at Nagano Children's Hospital during the preceding 4 months until January 1994. The tracheoesophageal fistulae were noticed after the first stage surgery for the aortic arch anomalies, because of the remarkable abdominal distension under the intubated and ventilated condition of general anesthesia. Both the bronchial and esophageal optical fiber examinations were performed which proved useful to detect the fistulae. In each case, the transcervical division of the fistula was performed on an emergency basis. The external diameter of the fistula was 4 and 5 mm respectively. The fistulae dilated synchronously with ventilation. The early detection and surgical correction of the tracheoesophageal fistula can prevent serious complications such as DIC as seen in the first case probably caused by respiratory infection associated with the prolonged mechanical ventilation. Successful intracardiac repair were performed in both cases on the 25th and 7th day following the correction of the fistulae respectively.

Pasteurella (P) multocida exists in a variety of animals and causes diverse infections in humans due to animal bites and scratches, usually by cats or dogs, and oral and respiratory infection. We report a case of P multocida sepsis due to a scratch from a pet cat, complicated with disseminated intravascular coagulation in a post-chemotherapy neutropenic patient with non-Hodgkin lymphoma. The patient was a febrile 79-year-old woman with disturbed consciousness and subcutaneous abscess in her right hand due to a scratch from a pet cat. She was successfully treated with empirical antibiotic therapy with cefepime and administrations of granulocyte colony-stimulating factor and danaparoid. The minimum inhibitory concentration of cefepime against the isolate from this case was <2mg/L. Although a few days are required before a diagnosis of P multocida infection can be made from a bacteriological study, the infection can be successfully treated against febrile neutropenia with empirical cefepime. In a literature review, 7 cases, including ours, with hematological malignancies complicated with P multocida infection were identified and we summarized the clinical characteristics of these cases. These cases demonstrate the importance of the prevention of close contact between pet animals and immunocompromised hosts such as post-chemotherapy neutropenic patients.

Coronavirus disease of 2019 (COVID-19) is a highly contagious respiratory infection that is caused by the severe acute respiratory syndrome coronavirus 2. Although most people are immunocompetent to the virus, a small group fail to mount an effective antiviral response and develop chronic infections that trigger hyperinflammation. This results in major complications, including acute respiratory distress syndrome, disseminated intravascular coagulation, and multiorgan failure, which all carry poor prognoses. Emerging evidence suggests that the complement system plays a key role in this inflammatory reaction. Indeed, patients with severe COVID-19 show prominent complement activation in their lung, skin, and sera, and those individuals who were treated with complement inhibitors all recovered with no adverse reactions. These and other studies hint at complement's therapeutic potential in these sequalae, and thus, to support drug development, in this review, we provide a summary of COVID-19 and review complement's role in COVID-19 acute respiratory distress syndrome and coagulopathy.
