Nelson's syndrome is a disorder that occurs in about one in four patients who have had both adrenal glands removed to treat Cushing's disease. [1] In patients with pre-existing adrenocorticotropic hormone ()-secreting pituitary adenomas, loss of adrenal feedback following bilateral adrenalectomy can trigger the rapid growth of the tumor, leading to visual symptoms (e.g. bitemporal hemianopsia ...
Median survival times for dogs of 662-900 days have been observed in pituitary-dependent cases treated with trilostane, and 353-475 days for adrenal-dependent cases treated with trilostane. [14] Survival rates of 72-79% have been observed in dogs with pituitary-dependent Cushing's four years after a hypophysectomy .
All layers of the adrenal gland stop functioning; the problem is with the adrenal gland. [8] This causes a deficiency of both mineralocorticoid and glucocorticoid secretion. Most cases are classified as idiopathic, although immune-mediated adrenocortical destruction is a likely cause.
After adrenalectomy for a cortisol-producing adenoma, patients should be treated with exogenous glucocorticoids such as cortisone or hydrocortisone until the hypothalamic-pituitary-adrenal (HPA) axis has recovered. This process may take 6 to 18 months after unilateral adrenalectomy.
Symptoms include liver and kidney failure and vasculitis. [10] Lyme disease* is a disease caused by Borrelia burgdorferi, a spirochaete, and spread by ticks of the genus Ixodes. Symptoms in dogs include acute arthritis, anorexia and lethargy. There is no rash as is typically seen in humans. [11]

Glaucoma in dogs is a painful condition caused by high pressure within the eye. Two types of glaucoma can affect our canine companions: primary and secondary. Glaucoma can lead to blindness if it ...
In this publication, the clinical symptoms of the disease, named after Cushing, were described. [ 30 ] [ 31 ] Out of the 12 cases with hypercortisolism described in Cushing's monograph on the pituitary body, 67% died within a few years after symptom presentation, whereas Minnie G. survived for more than 40 years after symptom presentation ...
