X-ray microanalysis of ossified auricles in Addison's disease.

The element content of ossified auricles in two patients with Addison's disease was determined by X-ray microanalysis. The results showed a similar element content of the ossified auricles of the Addison's patients and control bone specimens. The calcium and phosphorus content of the petrified auricles was, however, slightly decreased compared with the iliac bone biopsies of the patients.

New clinical applications of the stapedial reflex.

Stapedial reflex data were obtained from 11 myasthenic, 18 hyperthyroid and six hypothyroid patients. Data were studied with respect to reflex threshold, amplitude and decay. Elevated threshold, decreased amplitude, and high and low frequency reflex decay were observed in myasthenic and hyperthyroid patients.
