Q

In horses what is cushing disease caused by?

A

Pituitary adenomas are from pars intermedia

17
Q

Why are clinical signs in the horse different from the dog?

A

Because in the horse clinical signs are not a result of ACTH secretion generally it is from compression of the hypothalmus which causes clinical signs

18
Q

True or false in horses with pars intermedia you will see adrenocortical hyperplasia?

A

False NO adrenaocortical hyperplasia

19
Q

What is going on here and what does this result in?

A

rathkes pouch pituitary cyst resulting in pituitary dwarfism

20
Q

What disease will be seen in primary bilateral adrenocortical atrophy?

A

Hypoadrenocorticism- Addisons disease

21
Q

What type of tumor is this and where does it orginate from?

A

Pheochromocytoma which is a neuroendocrine tumor of the adrenal medulla

22
Q

What is happening in this picutre and what disease might be seen?

A

Adrenocortical atrophy, addisons

23
Q

This goat has this disease______which is know as thyroid______.

A

Goiter, thyroid hyperplasia

24
Q

True or false in goiter animals are hyperthyroid?

A

False hypo or euthyroid

25
Q

What woud you see on histo in thyroid hyperplasia?

A

Increase in thyroid follicles, proliferation and no colloid

26
Q

True or false: All proliferative lesions result in hyperfunction?

A

False

27
Q

What can decrease T4?

A

Lack of iodine

Brassica plants, sulfonimides

Excess dietary iodide

Lack of iodine

Interfearnce with production

28
Q

What lesions causeHYPOthyroidsm?

A

lymphocytic thyroiditis

thyroid atrophy

pitutary adenoma

thyroid carcinoma

29
Q

These two signs would be seen in severe hypothyroidsm

A

Myxedema, atherosclerosis

30
Q

Lesions underlying hyperthyroidism in cats?

A

Nodular adenomatous thyroid hyperplasia 70% bilateral

31
Q

Causes of SECONDARY Hyperparathyroidism

A

High P/ Low Ca

Renal disease - high P, low calcitriol

Inadequate D3

32
Q

Cause of primary hyperparathyroidism?

A

PTH producing Neoplasia

33
Q

Causes of Pseudoparathyroidsm

A

PTH-RP producing neoplasms Ex: adenocarcinoma, lymphoma

34
Q

In pseudo hyperparathyroidsim will PTH be increased or decreased?

A

It will be decreased because of negative feedback and you will have increased Ca

35
Q

In a pancreatic islet cell carcinoma with a beta cell tumor will you see increased or decreased insulin?

A

Increased leading to hypoglycemia

36
Q

In diabetes mellitus due to pancretic hypofunction will insulin be increased or decreased? Glucose increased or deacreased?

A

Decreased insulin increased blood glucose

37
Q

What is going on with this cats pancreas?

A

Amyloidosis , results in islet cell atrophy, insulin deficiency , can be seen in cats without DM monitor

38
Q

Associated lesions with diabetes mellitus

A

Microangiopathy
