Q

Hyperthyroid medication

A

Thionamides stop thyroid hormone synthesis

  • Methimazole
  • Propylthiouracil (PTU) (also works on peripheral)
    - High initial dose till obtain euthyroid status (free t3, t4 levels normal - then low daily maintenance dose

Q

High TSH
High Free T3 and T4 levels
what could cause

A

TSH secreting pituitary adenoma

diagnosed CT or MRI
Surgical removal through nose is treatment

20
Q

what causes unregulated thyroid hormone secretion in Hyperthyroidism

A

Nodules
(Toxic multinodular goiter)
Toxic Adenoma -single nodule

21
Q

Toxic multinodular goiter)
Toxic Adenoma -single nodule

treatment

A

Used iodine 131 for radioiodine therapy

22
Q

In radioiodine therapy what precautions

do not go around pregnant women or young children for 3 days…your radioactive

23
Q

Treatment for Thyroid Storm

A

Beta blockers
Thionamides
Glucocorticoids

24
Q

Parathyroid hormone and vitamin D work to raise or lower the calcium level

A

raise

25
Q

Calcitonin works to raise or lower the calcium level

A

lower

26
Q

blood calcium is regulated by what hormone

A

parathyroid hormone (PTH)

27
Q

How does PTH regulate Ca+

A

stimulates osteoclasts to break down bone to release Ca+

Kidneys reabsorb Ca+

synthesizes Calcitriol (active vit D) gets the GI tract to absorb Ca+

28
Q

What syndrome causes hypoparathyroidism

A

DiGeorge syndrome

29
Q

Chvostek’s sign and Trousseau’s sign are symptoms of

A

hypocalcemia

30
Q

Calcium and phosphorous have what kind of relationship

A

inverse

31
Q

treatment for hypoparathyroidism

A

Calcium and Vitamin D supplement

if that doesn’t work recombinant human parathyroid hormone

32
Q

which hyperparathyroidism is the parathyroid the problem

A

primary

33
Q

hyperparathyroidism which the parathyroid is normal but the gland makes excess PTH

A

secondary

34
Q

who have had secondary hyperparathyroidism for years …..make parathyroid hormone independently of blood calcium levels

A

Tertiary

35
Q

Symptoms of primary hyperparathyroidism

A

“stones”
- kidney and gallbladder

“thrones”
-polyuria

“Bones”
pain

“Groans”
Constipation
muscle weakness

secondary hyperparathyroidism is usually called by

A

chronic kidney disease

40
Q

the most common congenital cause of hypoparathyroidism
