[The Paget's disease--a gerontological study (author's transl)].

Authors found Paget's disease in cases among 1500 patients who considered themselves as healthy. They established their diagnosis on the basis of radiological and laboratory examinations. The incidence rate of Paget's disease was 0,7%, however it must be more frequent in the old groups. The familiar incidence of this illness is not frequent, thus it is rather intriguing that three persons i.e., 2 sisters and 1 brother is one family were found to have Paget's disease showing similar clinical and radiological symptoms. After three years the comparative examinations of two returning aged women showed a progress of Paget's disease. This manifested in exacerbation of osteopathy and increased the activity of the serum-alkaline-phosphatase. The cases of Paget's disease were reported by the authors because of the radiological interest, familiar incidence and the gerontological-geriatrical aspects.
