錐體尖端化膿症8例の總合的観察（第5報）

　昭和16年以來私は8例の錐体尖端化膿症を学会に報告したが，その後戰爭のために原著としての発表は遅れに遅れて，第4報は漸く昭和23年に掲載された．今回発表するこの8例の総合的観察も數年前に学会に発表したものである．私が本症に就て学会に発表した頃は，我邦ではこの研究が甚だ尠なかつた．それ故この総合的観察も相当意義があつたのである．併しその後この研究は急足の進歩を來して，幾多のよい観察が発表された（仁保，高原，中村，神尾氏等）ので，最早大した意義はない．只原著として発表しなかつたのでその責を果すに過ぎないのである．

　第1囘報告の山中，小沢例，第2囘報告の新田，荻根例，第3報告の小松，川井例，第4報告の川合，三好例の8例について年齡，性，症候，診断，中耳炎の急性慢性，起炎菌，氣胞化の程度，脳膜炎の合併，轉歸，経過日数，考察と云う條件を表を以て総括觀察する事にする．

Nishihata presents summary observations on 8 cases of petrositis which he had previously rep-orted in detail. As outstanding signs among these cases neuralgia occurred in 3 (orbital, 3 cases; dental, 1 case), headache in 5, and par-esis of the external muscle of the eye in 2. The basis of diagnosis was confirmed at the time of operation in 2 cases; on paresis of the ext-ernal muscle of the eye in 2 cases; on orbital and dental pain in 1 case; on headacha and otorrhea in 1 case; on headache and facal pare-sis in 1 case; and otorrhea and spinal fluid examination in the remaining 1 case. Bacterial agents found involved in the infection were that of streptococcus in 3 cases; that of muco-sus in 2 cases; and unknown in 3 cases. Cell pneumatization was found well developed in 4 cases, while it was poor in the remaining 4. Menigitis developed in 4 cases. Four cases were cured and the other 4 died. As unusual signs the author cites diffuse swelling in and about the wound of operation, which was seen in 2 cases. The report is concluded with detai-led comments on various topics as that of sym-ptoms and signs, diagnosis-and therapy of this idsease.
