36
Q

monitoring blood glucose

A

owners shown how to monitor urine glucose and sometimes BG, pets should have blood glucose curve every 2 weeks, fructosamine: reflection of blood glucose levels over 2-3 weeks

37
Q

insulinoma

A

functional tumor involving B-cells of pancreas which causes an over secretion of insulin

38
Q

clinical signs of insulinoma

A

severe hypoglycemia

39
Q

Dx insulinoma

A

serum chemistry reveals low BG, Ultrasound shows pancreatic tumor

40
Q

Tx insulinoma

A

correct hypoglycemia, high protein meals, glucocorticoids to antagonize insulin, diazoxide (inhibits insulin secretion), Sx

41
Q

prognosis of insulinoma

A

poor

42
Q

hypothalamic-pituitary-adrenal axis

A

hypothalamus (corticotropin releasing hormone) —> anterior pituitary (adrenocorticotropic hormone) —-> adrenal cortex —-> negative feedback

43
Q

hypoadrenocorticism common name

A

addisons disease

44
Q

what is addisons

A

deficiency in production of glucocorticoids or mineralocorticoids

45
Q

what are glucocorticoids

A

maintain normal blood glucose, by converting amino acids and fatty acids into glucose, maintains normal blood pressure by directing epinephrine to vasoconstricted areas, also has anti-inflammatory effect

46
Q

what are mineralocorticoids

A

responsible for regulating levels of electrolytes in the body

47
Q

signalment of addisons

A

middle aged dogs usually female

48
Q

breeds predisposed for addisons

A

labs, poodles

49
Q

clinical signs of addisons

A

vague, ADR, PU/PD, vomiting, diarrhea, bradycardia, hypotension, dehydration

50
Q

Dx of addisons

A

serum chemistry, ACTH stimulation test

51
Q

Tx of addisons

A

IV fluids, electrolyte therapy, glucocorticoid and mineralocorticoid replacement, monitor electrolyte and clinical signs

52
Q

hyperadrenocorticism common name

A

cushings disease

53
Q

what is cushings

A

overproduction of hormone cortisol by adrenal glands

54
Q

etiology of cushings

A

pituitary dependent (PDH): microadenoma 85-90%
adrenal tumors (ADH) <15%
iatrogenic

55
Q

signalment for cushings

A

dogs over 20 kg: PDH
dogs under 20 kg: ADH

56
Q

clinical signs of cushings

A

PU/PD, bilateral flank alopecia, polyphagia, excessive panting, pendulous abdomen, calcinosis cutis, skin infections, lethargy

57
Q

Dx cushings

A

CBC and serum chemistry, elevated urine cortisol, LDDS, ATCH stim test

58
Q

Tx cushings

A

depends on etiology

59
Q

causes of cushings; pituitary gland tumor

A

located at the base of the brain, 85-90% of cases, may be benign for malignant

60
Q

causes of cushings; adrenal gland tumor

A

adenoma/carcinoma, may be benign or malignant

61
Q

causes of cushings; iatrogenic

A

excessive cortisol from prolonged use of steroids

62
Q

other signs of cushings

A

increased appetite, weight gain, PU/PD, excessive panting, bilateral flank alopecia, hepatomegaly, skin infections, diabetes

63
Q

low dose dexamethasone suppression test

A

takes about 8 hours in hospital, when given dexamethasone, the pituitary gland perceives that as as steroid and will shut off the message to adrenal gland, there will be a drop in blood cortisol; if no drop occurs in 8 hours, a pituitary tumor is present

64
Q

ACTH test

A

requires 2 hours at hospital, dose of ACTH given to patient,if a larger than normal spike of cortisol in 1-2 hours, you can diagnose cushings

65
Q

urine cortisol; creatinine ratio

A

positive test does NOT mean cushings, but a negative test rules it out; urine is tested for cortisol levels

66
Q

risks for not treating cushings

A

euthanasia, diabetes, thromboembolism, increased infections, systemic hypertension, glomerular nephropathy

67
Q

signalment for equine cushings

A

older horses

68
Q

pathology for equine cushings

A

hypertrophy of pituitary, increased dopamine and increase in ACTH which increases cortisol

69
Q

clinical signs of equine cushings

A

shaggy coat, lethargy, sweating, recurrent laminitis, recurrent infections

70
Q

Dx equine cushings

A

dexamethasone suppression test; clinical signs

71
Q

Tx equine cushings

A

pergolide, treat other conditions

72
Q

similar to equine cushings

A

EMS (equine metabolic syndrome)

73
Q

what does the parathyroid gland do?

A

controls calcium in the body (bones and blood)

74
Q

what does calcium do in our body?

A

controls many body systems

75
Q

primary hyperparathyroidism

Dx primary hyperparathyroidism

A

serum Ca++, excessive PTH

Tx primary hyperparathyroidism

A

Sx removal of gland, vitamin D and Ca

79
