[Monthly rhythms of exacerbations and debuts of some diseases and sudden death].

A chronobiological analysis covering 355 adults and children with different diseases, cases of sudden deaths due to blood coagulation causes has revealed monthly hyper- and hypocoagulation periods. The hypercoagulation periods in which life-threatening thrombosis may occur were observed 8 days close to the new moon and 7 days after it as well as in the second phase of a monthly biorhythm. In the first phase of a monthly biorhythm there is a tendency to hemorrhage. In these days more attention should be given to patients who may develop hemorrhage to prevent threat to their life and sudden death.
