[Meteorologic effects on hemorrhagic diathesis in hemophilia. 1. Demonstrating weather effects based on a complex weather phase scheme]. / Meteorologische Einflüsse auf die Blutungsneigung bei der Hämophilie.1. Mitteilung: Darstellung der Meteorotropie anhand eines komplexen Wetterphasenschemas.

ABSTRACT

In haemophilia frequently spontaneous haemorrhages occur without recognition of an evoking cause. Various bleeding-disposing factors are discussed, among others also influences of weather. For the investigation of the meteorotropic relations 1,802 episodes of haemorrhages in 223 haemophiliacs were coordinated to a complex scheme of weather phases. An undisturbed course of the weather was in general connected with a decrease of bleeding, whereas in an influence of low pressure with advection of cold air an increase of the haemorrhages was established. Conspicuous was furthermore the negative biotropism of the radiation-intensive sunny fine weather in summer, which is probably to be traced back to the thermic load in this weather situation.
