The geographic distribution and effect of climate on eclampsia, toxemia of pregnancy, hyperemesis gravidarum, and abruptio placentae

摘要: Abstract The geographic distribution of eclampsia, toxemia pregnancy, hyperemesis gravidarum, and abruptio placentae has been studied. These diseases are peculiar to pregnancy the incidence should, therefore, be constant throughout world. Eclampsia, because its striking symptoms signs, used as index. Collected data show that ranges from 0 in many cities 2.85 per cent Algiers, Africa, 7.2 Charlotte, North Carolina. mean for world is 1.0 cent, United States 0.66 British Isles 1.13 Europe 0.68 rest 0.52 cent. eclampsia meteorologic various have studied statistically. There some correlation, especially States, between a high average temperature, small range measure rainfall. Our seem indicate may undoubtedly does occur native who had little or no contact with modern civilization. However, latter mental strain stress, change diet habits seems cause an increase occurrence eclampsia. results warrant further investigation these diseases, means of, first, determining pertinent factors, second, eliminating preventing them, third, their relation etiology disease question.
