OTITIC BRAIN ABSCESS IN GENERAL
Lund,1 in an article entitled "Otogenic Brain Abscess," reviews the material from the Copenhagen Hospital, which comprises fifty-six cases of otogenic brain abscess. He says that males are affected more than twice as often as females; children rarely under 1 year of age. Fifty brain abscesses originated from chronic middle ear suppuration; six were due to acute ear suppuration. Right-sided cerebral abscesses are more common than left-sided. Cerebellar abscess was observed with about equal frequency on the right and left sides. The streptococcus, which predominates in epidural perisinuous abscesses, occurs relatively less, often than the pneumococcus in otogenic meningitis. In brain abscess the pneumococcus and Bacillus coli predominate, the latter greatly aggravating the prognosis. The fifteen cases in which B. coli was demonstrated terminated fatally. As distinguished from pneumococcus abscesses (with their relative tendency to membrane formation), an abscess from B. coli
