Symptoms of myxedema:
Major S/S of hypothyroid: 95% of hypothyroid is what type? |
large tongue, sparse hair, dull expressionless face, periorbital puffiness, pale, doughy skin, hypothermia, stupor
cold intolerance, hoarseness, DTR delayed relaxation, goiter, lethargy, constipation, weight gain primary - thyroid destruction |
|
|
Permanent causes of primary hypothyroid:
Reversible causes: Permanent causes of secondary hypothyroid: Reversible cause: |
Hashimoto's, primary atrophy, postablative
iodine deficiency, hypothyroid phase of subacute, silent thyroiditis HP disease, postpartum necrosis, tumors withdrawal of thyroid hormone therapy in euthyroid person |
|
|
Describe TSH, and free T4 in:
Primary hypothyroid Primary hyperthyroid TSH producing tumor Central hypothyroid |
Primary hypothyroid - High TSH, Low FT4
Primary hyperthyroid - Low TSH, High FT4 TSH tumor - High TSh, High FT4 Central hypothyroid - Low TSH, Low FT4 |
|
|
S/S of thyrotoxicosis:
S/S of hyperthyroid: |
nervousness, palpitations, wide pulse pressure, systolic murmurs, emotional lability, frequent poops, sweating
heat intolerance, tremors, wt loss, erythematous palms, Plummer's nails, fine silky hair, exophthalmos |
|
|
Exogenous, endogenous causes of hyperthyroid:
Examples of abnormal thyroid regulation: |
exogenous - thyroid hormones, iodides
endogenous - primary thyroid (nodular goiter, thyroiditis, follicular carcinoma) Grave's - TSI acts as TSH, stimulates thyroid production TSH tumor, hCG by hyatidiform mole |
|
|
Describe I-131 uptake in Grave's, resolving thyroiditis, ectopic struma, surrepitous thyroid hormone use:
How to eval for neonatal thyrotoxicosis: Ab tests for hypothyroid: |
increased in Grave's, decreased in everything else
check mother in 3rd trimester for TSI Anti-TPO, AMA |
|
|
Drugs for hypothyroid, hyperthyroid:
SE's of hyperthyroid meds: Likely result of I-131 ablation: Adjunct for tachycardia: |
hypo - Synthroid (levothyroxine)
hyper - PTU, Methimazole more common with PTU - agranulocytosis, vasculitis, hepatitis, aplastic anemia hypothyroid BB's |
|
|
Euthyroid sick syndrome:
|
severe illness, physiologic stress, physical trauma
TSH normal, T3 low, impaired conversion from T4 (peripheral proteins altered) |
