early and late prognosis following valve replacement for bacterial endocarditis of the native valve. | between 1983 and 1922 70 patients of the author's institution underwent valve replacement for bacterial endocarditis of native valves. in 22 cases the source of infection could be identified. among them the most frequent source of infection was dental manipulation (7 patients). the predominating causative microorganism was streptococcus viridans followed by staphylococcus aureus. preoperative complications, the intraoperative finding of extensive destructions, and the histological finding of acu ... | 1995 | 7545333 |
a randomized, controlled trial of the efficacy of a heparin and vancomycin solution in preventing central venous catheter infections in children. | to determine whether adding vancomycin to central venous catheter (cvc) flush solution would significantly reduce the incidence of bacteremia attributable to luminal colonization with vancomycin-susceptible organisms. | 1995 | 7608801 |
premacular hemorrhage as a sign of subacute bacterial endocarditis. | purpose/methods: we examined a patient with mitral valve insufficiency, a sudden decrease in vision in the right eye, and premacular hemorrhage, which was a sign of subacute bacterial endocarditis. results/conclusion: the patient was hospitalized and treated with intravenous antibiotics. blood cultures grew streptococcus viridans. ocular symptoms and signs improved over two months. premacular hemorrhage may be a sign of subacute bacterial endocarditis and may obscure other classic signs. subacut ... | 1995 | 7639311 |
infective endocarditis in children: profile in a developing country. | with the object of studying the profile of infective endocarditis in indian children younger than 16 years of age, a retrospective study of 37 patients with infective endocarditis admitted to this hospital between january 1984 and december 1990 was carried out. there were 26 boys and 11 girls (aged 2-16 years (mean (sd) 10.3 (3.8)). eighteen (48.6%) patients had underlying congenital heart disease, 13 (35.1%) had associated rheumatic heart disease whilst the remaining six had no pre-existing hea ... | 1993 | 7687116 |
[the acquired immunodeficiency syndrome, hypertrophic myocardiopathy and multivalvular infectious endocarditis. apropos a clinical case]. | we present a clinical case of a 33 years old young male, gypsy, intravenous drug abuser with heroine and cocaine and aids diagnosis. the clinical anamnesis was mainly fever and systolic heart murmur in a clinical scenario of aids. the two-dimensional echocardiographic study was clearly diagnostic of an hypertrophic obstructive cardiomyopathy of the left ventricle. this study showed also the presence of multiple vegetations of the mitral, aortic and pulmonic valves in a clinical setting of an acu ... | 1995 | 7695955 |
bivalvular endocarditis complicating pregnancy. a case report and literature review. | a twenty-nine-year old woman with a history of rheumatic fever and both mitral and tricuspid valve prolapse (without cardiac effects on the echocardiogram) presented with streptococcus viridans infective endocarditis of both the tricuspid and mitral valves at seventeen weeks' gestation. twelve weeks before admission she underwent a dental curettage and received presumably adequate antibiotic prophylaxis. the present case was successfully managed by means of aggressive antibiotic therapy appropri ... | 1995 | 7741329 |
splenic abscess: a diagnostic pitfall in the ed. | splenic abscess, with its rare incidence and various misleading clinical manifestations, usually is a diagnostic pitfall in the modern emergency department. the most frequently seen symptoms and signs are fever, abdominal pain and tenderness over left upper quadrant, splenomegaly, leucocytosis, and left lower chest abnormalities. four cases were collected during the past five years. on admission, one patient manifested symptoms mimicking a perforated peptic ulcer and the other three patients pre ... | 1995 | 7755833 |
sinusitis and bronchial asthma in children. | sinus disease has been assumed to exist in children with respiratory tract allergies. we consecutively evaluated 375 patients (245 male, 130 female) with childhood onset asthma, between 5 and 15 years of age (mean 7.8 years of age). abnormal waters radiographs were found in 205 patients (54.7%) which included mucosal wall thickening greater than 6 mm (67.3%), complete opacification (22.9%) and air-fluid levels (9.8%). the level of immunoglobulin (ig) e was found to be much higher in non-sinusiti ... | 1995 | 7778440 |
