title: Staphylococcus aureus meningitis. A review of 104 nationwide, consecutive cases.
abstract: METHODS
  Based on a nationwide registration, the clinical and bacteriologic data from 61 postoperative and 43 hematogenous cases of Staphylococcus aureus meningitis in Denmark from 1986 through 1989 were reviewed.
  
  
  RESULTS
  Postoperative meningitis was a foreign body infection in 89% of the cases and had a lower mortality (18% [11/61]) compared with hematogenous meningitis (56% [24/43]). Hematogenous S aureus meningitis seems to be part of an overwhelming, disseminated infection as indicated by the following: 81% of the patients had bacteremia, 21% had endocarditis, and 12% had osteomyelitis. Most patients were older, often with underlying diseases, community-acquired infections, and a clinical picture of severe meningitis. The major findings were mental status changes and a high rate (34%) of focal neurological changes. The initial leukocyte count in the cerebrospinal fluid sample was low, and the bacteria were seen in Gram's stain smears in 40% of cases only. The prognosis was related to the age of the patients and the initial antibiotic treatment. Patients treated with penicillinase-stable penicillins in combination with fusidic acid may have a better prognosis. Three (12%) of 25 surviving patients had severe sequelae.
  
  
  CONCLUSIONS
  Hematogenous S aureus meningitis is a severe disease with a high mortality related to age, presence of shock, and infection with strains of phage type 95.
