Houssay's phenomenon
Also known as:
Houssay’s phenomenon in man
Houssay’s syndrome
Houssay-Biasotti syndrome
Associated persons:
Alfredo Benito Biasotti
Bernardo Alberto Houssay
Description:
Spontaneous remission of diabetes mellitus – «vanishing diabetes» – by a destructive lesion in, or surgical removal of, the anterior pituitary gland. This is the clinical counterpart of the posthypophysectomy remission of diabetes mellitus in pancreatomised animals, observed during experiments by Houssay and Biasotti.
This is reallyu two entities:
Houssay phenomenon: Amelioration of diabetes mellitus following ablation of the pituitary.
Houssay syndrome: Improvement of the diabetic state in patients following pathological disease of the pituitary, causing hypopituitarism, usually due to a vascular or infiltrate cause (tuberculosis or sarcoidosis).
The phenomenon was first described in humans by the Hungarian neuropathologist Jósef Baló (1896–) in 1924, and R. M. Calder in 1932.
