title: [Three interesting pediatric cases with penicillin-resistant Streptococcus pneumoniae infection].
abstract: Since penicillin-resistant Streptococcus pneumoniae first recognized in 1967, the rate of penicillin-resistant strains has been increasing worldwide. There have been up to 50% from pediatric specimens in Japan. We reported three pediatric cases with penicillin G resistant Streptococcus pneumoniae infection to show some important clue from these cases for clinical practice against resistant pneumococcal infection. The first case was a typical acute mastoiditis, although we have experienced only masked mastoiditis recently. The second case was meningitis with septicemia, which did not show any abnormality in the first obtained cerebrospinal fluid. The third case was recurrent bronchitis in a child with cerebral palsy. The minimum inhibition concentrations of these isolated strains were 0.25 microgram/ml in the second case an 2.0 microgram/ml in the first and third cases.
