Racial Variations in Immunity to Syphilis

Treponematoses e outras paleopatologias em sítios arqueológicos pré-históricos do litoral sul e sudeste do Brasil

“…Existe grande variação nas frequências de lesões ósseas sifilíticas que variam ao (j. Filippini -2012) redor de 1% nos países nórdicos (Gjestland, 1955), até 27% na China (Frazier & Hung-Chiung, 1948) e 20% na Rússia antes da existência da penicilina (Bauer & Carvati, 1967). A maior incidência anual atualmente conhecida é do Sudão com 3,7% (Guthe, 1964a e b).…”

Their figures were 18-1 years for males and 14 1 years for females, and these were arrived at by deducting from the mean ages of the cardiovascular patients under their study the mean ages of the males and females arriving at their clinic with fresh infections at the time of their study.…”

“…As another example of the difficulty of comparing series in different countries with each other, Gjestland quotes the findings of Frazier and Li (1948) various disturbances of the socio-economic equilibrium. Therefore, whenever we choose a relatively large population-group of syphilitics for study, we invariably end up with patients who by and large come from the lower socio-economic strata of society.…”
