Table VI, it will be seen, shows the aneurism incidence in Fili- 

 pinos to be 0.382 per cent, which is very low when compared with 

 the aneurism incidence in Chinese, 4.34 per cent, and the 

 aneurism incidence in Americans, 7.88 per cent. This low 

 aneurism incidence in Filipinos is similar to the low aneurism 

 incidence in the natives of India, which Rogers gives as 0.36 

 per cent. 



ETIOLOGIC AGENTS AND LESIONS ASSOCIATED WITH ANEURISMS 



Syphilis. — Syphilis is probably the cause of all the aneurisms 

 of this series, and in all cases there were other associated lesions 

 of syphilis, such as arteritis, gummata, and osteitis. The pre- 

 valence of syphilis in the Philippines is discussed under atheroma. 



Blood pressure and strains. — In this series of aneurisms there 

 could not be obtained any reliable histories or recorded blood 

 pressures. Some of the cases in Filipinos occurred in farmers 

 and sailors, while in the Chinese some occurred in those who 

 performed heavy manual labor ; in the Americans and Europeans 

 the cases varied from those who performed heavy manual labor 

 to those who did clerical work. The case occurring in a Japanese 

 was in a prostitute. 



Hypertrophy of the heart. — Hypertrophy of the heart occurred 

 in 67.5 per cent of all cases, while 32.5 per cent were either 

 normal in size or smaller than normal. 



Chronic interstitial nephritis. — Chronic interstitial nephritis 

 occurred in 65 per cent of all the cases, while 35 per cent showed 

 apparently normal kidneys.
