OBJECTIVE To assess the echocardiographic findings in patients with suspected infective endocarditis. METHODS Two hundred sixty-two patients with suspected infective endocarditis underwent transthoracic and transesophageal echocardiographic investigation. Images of vegetations, valvular abscesses, and acute periprosthetic insufficiency were analyzed, and the correlation with clinical and labo...
A 13-year-old boy with a small ventricular septal defect was admitted with clinical manifestations of acute endocarditis. Coagulase-positive staphylococci were isolated from the blood. Definitive diagnosis was made by detecting bacterial vegetations in the right ventricle on the echocardiogram. Repeated embolization of these vegetations to the pulmonary circulation led to the death of the patient.
Using a rabbit model of Staphylococcus aureus endocarditis, we studied the effects of aspirin on the natural progression of this infection. Compared with untreated animals, the aspirin-treated animals showed a 30% (P = 0.11) reduction in the weight of the vegetations and an 84% (P = 0.03) reduction in the bacterial titer of the vegetations.
This study evaluated the daptomycin activity against two methicillin-resistant Staphylococcus epidermidis (MRSE) clinical isolates with different vancomycin susceptibilities: MRSE-375, with a vancomycin MIC of 2 microg/ml, and NRS6, a glycopeptide-intermediate S. epidermidis (GISE) strain with a vancomycin MIC of 8 microg/ml. The in vivo activity of daptomycin at two different doses (standard d...
In the pathogenesis of bacterial endocarditis (BE), the clotting system plays a cardinal role in the formation and maintenance of the endocardial vegetations. The extrinsic pathway is involved in the activation of the coagulation pathway with tissue factor (TF) as the key protein. Staphylococcus aureus is a frequently isolated bacterium from patients with BE. We therefore investigated whether S...
Weights of curetted adenoid were measured and were compared with both weights of tonsils and the rate of adenoidectomy among the tonsillectomized cases. This study included 603 patients whose adenoids were curetted during the 11-year period. 90% of patients were 2 to 9 years old. The rate of curetted adenoid vegetation among the tonsillectomized cases was 80% among patients from 1 to 6 years ol...
Rabbits with established staphylococcal endocarditis, injected twice at an interval of 2 h with either 0.5 mg of cloxacillin per kg or saline, were sacrificed 2.5 h after the second injection. Vegetations were excised, weighed, and cultured, and ultrathin sections were prepared and examined by light microscopy, transmission electron microscopy, and scanning electron microscopy. Several affected...
