| [surgical aortic valve replacement for acute streptococcus viridans endocarditis with simultaneous moderate hemophilia a]. | this is a report of a 25-year-old patient with known aortic valve stenosis since early youth and hemophilia a, showing recurrent joint bleeding. acute streptococcus endocarditis induced aortic valve insufficiency resulting in cardiac failure. aortic valve replacement was performed after substitution of factor viii, during which intra- and postoperative bleeding was prolonged by pericardial adhesions. heparin was administered during cardiopulmonary-bypass as usual, but usual postoperative cumarin ... | 1988 | 3145652 |
| 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 |
| infective endocarditis in children with congenital heart disease: the changing spectrum, 1965-85. | thirty-five episodes of infective endocarditis in 35 children with congenital heart disease, from january 1965 to december 1984, were reviewed. the incidence of infective endocarditis in cyanotic congenital heart defects increased with a concomitant decrease in the frequency of lesions with left to right shunt. the incidence of postoperative endocarditis decreased from 1:52 during the first decade to 1:1033 during the second decade. the time interval between onset of symptoms and the establishme ... | 1988 | 3234417 |
| 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 |
| streptococcal endophthalmitis from contaminated donor corneas after keratoplasty. clinical and laboratory investigations. | we report three cases of streptococcus viridans endophthalmitis following penetrating keratoplasty in which s viridans was cultured from the recipient eye, mccarey-kaufman (m-k) media, and corneoscleral rims. as a laboratory correlation, we investigated the ability of s viridans to survive in m-k medium supplemented with gentamicin. after m-k medium was inoculated with s viridans, it was stored overnight at 4 degrees c, after which the temperature was raised to 23 degrees c. periodic colony coun ... | 1988 | 3281643 |
| [pleural empyema due to streptococcus milleri]. | thus far little attention has been focused on the precise identification of streptococcus viridans to species level and the clinical relevance of streptococcus milleri, yet there is growing evidence that closer identification would be of significant clinical value. streptococcus milleri was identified in 142 isolates from approximately 120 patients over a period of 12 months (june 1984-may 1985) at the institute of medical microbiology, zurich university hospital. pleural empyema was the source ... | 1987 | 3303315 |

| 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 |
| role of the vegetation in experimental streptococcus viridans endocarditis. | this study examines the role of the vegetation in catheter-induced experimental endocarditis in predisposing to bacterial colonization of cardiac valves and in influencing the course of the disease and response to penicillin therapy. platelet-fibrin vegetations developed at areas of valvular trauma and were colonized when streptococcus viridans were injected intravenously. pretreatment with warfarin prevented vegetation formation, but animals still developed endocarditis at the same rate after i ... | 1974 | 4497487 |
| [identification of streptococcus viridans in clinical specimens]. | in a 4 year prospective study of "viridans" or non-groupable streptococci 100 clinically significant strains were isolated. strains were defined as significant when found in two or more samples of blood cultures, or when seen on gram staining together with inflammatory reaction. fifty-two strains were speciated by 10 physiological characteristics. in 42 cases additional tests were performed. only 16 isolates were unidentifiable by the techniques used. sources of isolates included purulent lesion ... | 1987 | 3685392 |
| mitral valve aneurysm formation documented by cross-sectional echocardiography. | we report a case of mitral valve aneurysm secondary to streptococcus viridans endocarditis of the mitral valve. cross-sectional echocardiography demonstrated an initial thickening of the anterior mitral leaflet which evolved further into an aneurysm. surgery showed that this lesion had subsequently perforated. this case highlights the ability of echocardiography to detect gradual anatomic changes in the course of bacterial endocarditis. the diagnosis of such abnormalities might have important th ... | 1986 | 3699053 |
| immunosuppressive therapy and plasmapheresis in rapidly progressive glomerulonephritis associated with bacterial endocarditis. | a 25-year-old male presented with new cardiac murmurs and acute renal insufficiency. blood cultures grew streptococcus viridans and appropriate antibiotic therapy was initiated. a renal biopsy revealed diffuse proliferative glomerulonephritis with crescents involving more than 50% of the glomeruli. treatment with antibiotics, plasmapheresis, and steroids resulted in renal recovery that paralleled reductions in circulating immune complexes. the rationale for this therapeutic approach is discussed ... | 1986 | 3706297 |
| effect of chlorhexidine 0.5% on the hand bacterial flora. | the effects of cleaning the dorsal hand with chlorhexidine 0.5% in spirit was evaluated by bacteriological study in 45 adult patients. in the absence of cleaning it was found that the prevalent microorganisms were staphylococcus epidermidis, staphylococcus aureus, streptococcus viridans and enterobacteriaceae. cleaning the hand with chlorhexidine 0.5% eliminated all bacteria except s. epidermidis and s. aureus. in both instances, the culture results showed that the microorganisms were present in ... | 1986 | 3776454 |
