Hypoadrenocorticism in dogs, or, as it is known in people, Addison's disease, is an endocrine system disorder that occurs when the adrenal glands fail to produce enough hormones for normal function. The adrenal glands secrete glucocorticoids such as cortisol [ 1 ] and mineralocorticoids such as aldosterone ; [ 2 ] when proper amounts of these ...
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.
Hypothyroidism is classified as either primary, secondary, or tertiary. Primary hypothyroidism is for when the cause is due to an abnormality of the thyroid gland, secondary hypothyroidism is when the cause is decreased thyroid-stimulating hormone levels, and tertiary hypothyroidism is when the cause is an inadequate amount of thyrotropin-releasing hormone being released.
Imaging of the pituitary gland is important in confirming hypersomatotropism in cats where it is suspected. Showing a pituitary mass is important to establish a final diagnosis alongside clinical findings and hormonal findings. Knowing the size of the pituitary mass is also necessary to decide the best course of treatment.
Pituitary gland tumors are very common in the canine. A productive form arising from the anterior pituitary is the primary cause of Cushing's disease of dogs. This tumor causes excessive production of cortisol from the adrenal cortex which leads to the classic signs of alopecia (hair loss), polyuria (excessive urination), polydipsia (excessive water drinking), and a pot-bellied appearance of ...
Acromegaly (also known as hypersomatotropism) is a hormonal condition resulting from over-secretion of the growth hormone somatotropin [130] from the pituitary gland. [131] The hormone is responsible for growth from birth to adulthood. Normally in adulthood, the growth plates of the bones close and the secretion of the hormone slows considerably.
When you buy a bottle of vitamins from a nutrition store, you’ll probably notice a best-by date on the bottom of the jar. But that inscribed number isn’t a hard-and-fast rule—there is some ...
The hypothalamic–pituitary–thyroid axis (HPT axis for short, a.k.a. thyroid homeostasis or thyrotropic feedback control) is part of the neuroendocrine system responsible for the regulation of metabolism and also responds to stress. As its name suggests, it depends upon the hypothalamus, the pituitary gland, and the thyroid gland.
