| sudden death due to left coronary artery occlusion in infective endocarditis. | a 44-year-old man died suddenly, shortly after admission to the hospital with complaints of abdominal pain. medical history was significant for chronic alcoholism and homozygous hemoglobin c disease. autopsy revealed vegetations on the aortic valve, especially on the left coronary cusp. there was anomalous origin of the coronary arteries from the left sinus of valsalva. the large vegetation on the left coronary cusp had extended into the left main-stem coronary artery and obstructed it. there wa ... | 1988 | 3415444 |
| recent trend of chemotherapy for infective endocarditis in japan. | out of the 10 patients with infective endocarditis (ie) at kawasaki municipal hospital, 8 had ie due to streptococcus viridans. out of 8 patients with streptococcus ie, 6 were successfully treated with benzyl penicillin alone or in combination with kanamycin. one patient was cured with cephaloridine. two hundred and thirty ie patients admitted to hospitals at kantou district were also studied. ninety nine of 116 patients with streptococcus viridans ie were successfully treated with potentially a ... | 1985 | 4021065 |
| infective endocarditis in children. | the clinical manifestations, infective microorganisms, underlying diseases, complications and prognosis of infective endocarditis (ie) were studied in 17 current patients. data were compared with 101 previous cases reported in japan. most patients with ie (110/118 = 93.2%) had underlying heart diseases. ie was noted most often in patients with ventricular septal defect (vsd) and tetralogy of fallot. the incidence of post operative endocarditis was high (29.4% in the present series and 9.0% in th ... | 1985 | 4021067 |
| extracranial mycotic aneurysms in infective endocarditis. | nine of 217 (4.15%) patients with infective endocarditis who were followed from october 1978 to february 1984 had extracranial mycotic aneurysms (ma). age range of patients was 6-43 years (mean of 24.8 years) and 7 were male. etiologic agents were streptococcus viridans (3 cases), staphylococcus aureus (2 cases), staphylococcus epidermidis (1 case), and pseudomonas aeruginosa (1 case). two patients had negative blood cultures. the ma involved the arteries of the limbs (5 cases), thoracic (3 case ... | 1986 | 3512135 |
| septic arthritis due to aerococcus viridans. | a 20-year-old woman was found to have septic arthritis of the hip due to aerococcus viridans. this organism closely resembles streptococcus viridans, but forms gram positive tetrads rather than chains in broth media. the organism has been reported rarely to cause endocarditis and one case of osteomyelitis has been observed. to our knowledge septic arthritis due to aerococcus viridans has not been previously reported. | 1985 | 4087248 |
| infective endocarditis in swedish children. i. incidence, etiology, underlying factors and port of entry of infection. | a retrospective study of swedish children with infective endocarditis (ie) during the period 1971-80 was made. sixty-six instances were identified in 64 children (0.39 cases per 100,000 children per year). fifty (78%) had a previously known heart disease. most commonly this was a ventricular septal defect and tetralogy of fallot. seventy-one percent had positive blood cultures. streptococcus viridans and staphylococcus aureus were most commonly isolated. twenty-two percent of the children had un ... | 1986 | 3564983 |

| factors influencing mortality from infective endocarditis in two district general hospitals. | factors influencing mortality were studied in 92 consecutive cases of infective endocarditis admitted to two district general hospitals between january 1975 and april 1982. thirty two patients died, an overall mortality of 35%, 13 patients died before diagnosis and 19 despite aggressive antimicrobial therapy. bactericidal antibiotic levels were monitored in 39 cases but these did not appear to influence outcome. mortality was lowest for streptococcus viridans infection (15%) but rose to 50% for ... | 1987 | 3671266 |
| left atrial myxoma infected with streptococcus viridans. | a case is described of streptococcus viridans endocarditis involving a left atrial myxoma. the diagnosis was made by echocardiography and the infected tumour was successfully treated by surgical removal. a review of the published literature about left atrial myxomas underlines the importance of performing echocardiography in all patients with suspected endocarditis. | 1988 | 3068157 |
| immunocompromised animal models for the study of antibiotic combinations. | studies of various models of pseudomonas aeruginosa infections in neutropenic animals have demonstrated the superiority of the combination of beta-lactam and aminoglycoside antibiotics when compared with a single drug alone. a limited number of studies carried out in models of klebsiella pneumoniae infections in neutropenic animals have shown similar results. the efficacy of double beta-lactam combinations for the treatment of gram-negative bacillary infections has not been studied as extensivel ... | 1986 | 3087166 |
| post-mortem bacterial culture of bronchial mucus and heart blood in hospital and non-hospital autopsies: effect of morgue time and length of hospitalization. | we studied cultures of 109 bronchial mucus and 67 heart blood specimens from unselected hospital autopsies and 40 bronchial mucus and heart blood specimens from unselected non-hospital (forensic) autopsies, performed 1-11 days after death. the most prevalent bacterium was streptococcus viridans. no association was found between morgue time and the number of species isolated from each bronchial mucus or heart blood specimen in either hospital or non-hospital autopsies, nor between morgue time and ... | 1986 | 3096018 |
| preterm labor: stimulation of arachidonic acid metabolism in human amnion cells by bacterial products. | there is a strong association between preterm labor and infection. some potentially pathogenic bacteria have phospholipase activity, and it has been suggested that release of phospholipase from these organisms may increase prostaglandin e2 synthesis in amnion cells and hence initiate preterm labor. in this study we established monolayer amnion cell cultures from tissue collected at elective cesarean section at term before labor. cells were prelabeled with tritiated arachidonic acid and then furt ... | 1987 | 3103451 |
| microbiological and pharmacological behavior of 7-chlorolincomycin. | replacement of the 7-(r) hydroxyl group of lincomycin by a 7-chloro-substituent produced a compound with greater in vitro activity than the parent. laboratory studies of this compound showed it to be highly active against all of the following strains of gram-positive organisms examined, including penicillinase- and nonpenicillinase-producing staphylococci, diplococcus pneumoniae, streptococcus viridans and streptococcus pyogenes. the enterococci, as well as all the gram-negative organisms tested ... | 1969 | 4389137 |

| propionibacteria isolates and asymptomatic infections of the peritoneal effluent in capd patients. | during the past two years our laboratory has isolated propionibacterium-an anaerobic gram-positive rod-on 40 occasions from the drainage fluid of 25 patients on capd and eight on ipd. most patients had no symptoms and the fluid was sent for culture after treatment of peritonitis, during training period, and occasionally because it was cloudy. no association was found with patients' age, length on dialysis, or previous peritonitis episodes. the only statistically significant association (p = 0.03 ... | 1986 | 3110672 |

| multiple brain abscesses secondary to dental caries and severe periodontal disease. | a case is reported in which an intra-oral focus of sepsis is thought to have resulted in the patient developing multiple brain abscesses without the presence of lung infection or cardiac valvular disease. the link between the two sites of infection is supported by the isolation of two streptococcus viridans species normally associated with dental caries and periodontal disease. the management of multiple brain abscesses is discussed. | 1988 | 3165021 |
| management of catheter-related infections in pediatric patients. | broviac catheters are commonly used to provide parenteral nutrition and access for infusion of blood products and drugs to pediatric patients. sepsis is the most common serious complication of continued catheter use. although removal of the catheter is generally recommended when it becomes contaminated, it may not be feasible to do so without compromising patient care. we evaluated the management of catheter-related infections in pediatric patients with and without removal of catheter. seventy-s ... | 1988 | 3278159 |
