96 patients with meningitis due to Neisseria meningitidis and Diplococcus pneumoniae were treated with epicillin or ampicillin according to a predesigned randomization chart. Results indicate that epicillin and ampicillin are effective single drugs in the treatment of meningococcal and pneumococcal meningitis. No adverse reactions were noted with either drug and they were comparable in their efficacy.

28 patients with bacterial meningitis received ampicillin by the intramuscular (IM) route and 16 patients by the intravenous (IV) route. The mean cerebrospinal fluid (CSF) ampicillin levels were similar in the two groups 1 h after a dose given on the first or second day of treatment, but they were higher in the IM group on both days 4 h after a dose. CSF/serum ratios were similar in both groups but considerably higher at 4 h than at 1 h.

Hearing affection as a sequel of meningococcal meningitis and its relation to age, sex, severity and duration of disease was studied in Cairo, Egypt during the period December 1966--December 1973. The total incidence of impaired hearing in the 775 cases was 5.8%. This incidence was higher in the younger age groups, females, severe cases of meningitis and in patients who received specific therapy shortly after the onset of signs and symptoms of the disease. The aetiology of hearing impairment in meningitis was reviewed.
