Penicillinに依る隠蔽作用の1例（耳性腦膿瘍）に就て

　緒言

　最近化學療法の進歩に依り急性疾患，特に急性中耳炎に依る手術は激減を示して居る．その爲にあまりに此の化學療法を信ずる亊に依り手術時期を遲らせ重大なる結果を來すことは鳥居教授の報告せられて居る如く時に見られるものである．予は此の化學療法，特にPenicillin大量使用に依り，その症状が隠蔽せられ急性中耳炎より腦膿瘍を發來せる患者で，その手術時期を遅らせ遂に死亡せる1例を經驗したので此所に報告する次第である．

Nomura report a case of otitis media that progressed to death of the patient from mastoiditis and intracranial complications. The cause of the comgli-cations are ascribed to possible concealment of sympoms which ordinarily would be recognized by use of penicillin (2,440,000) from the very beginning of the onest of otitis media anp by which operative treatment was undully delayed. The patient complain-ed of localized unilateral headache from the start of the otitis, a fact which calls for consideration with with a great importance, and it is suggestive that extJa-dural abcess might have been present from that time. There was no evidence either by clinical examination or necropsy that petrositis was involved in the picture. Staphylococcus aureus alone was found to be the causative organism.
