[Prosthetic valve endocarditis].

Infective endocarditis occurs in 4% of prosthetic valve carriers. The infection is related to both the injured endocardium and circulating microorganisms. Early prosthetic endocarditis, occurring in the first 12 months after valvular surgery is mainly caused by staphylococci, and late prosthetic endocarditis has a similar etiology as native valve endocarditis. Clinical manifestations of early cases are due to both bacteremia and prosthetic malfunction. In late cases the clinical picture is similar to native valve disease. Mortality in prosthetic endocarditis remains high, especially in early cases, despite combined medical and surgical treatment.

[Meningitis caused by Staphylococcus aureus. Analysis of 16 cases].

During the period between 1982 and 1987, 16 cases of meningitis due to Staphylococcus aureus were diagnosed. Nine patients (56%) had undergone a previous neurosurgical operation and 5 of them were carriers of a cerebrospinal fluid (CSF) shunt. Seven patients (44%) had spontaneous meningitis. Fever and meningeal signs were the most common clinical findings. 50% of patients were comatose. The Gram stain of CSF showed Gram positive cocci in 7 cases. Blood cultures were positive in all patients with spontaneous meningitis and negative in the neurosurgical group. Overall mortality rate was 37.5%, and it was lower in the neurosurgical group than in the spontaneous meningitis. Other factors associated with a poor outcome were advanced age, bacteremia and septic shock.
