Clinical presentation | Pathophysiology | Histopathological/gross appearance | Treatment/ Lab Tests | Miscellaneous |
---|---|---|---|---|
What is Graves Disease
weight loss, hot flashes, bilaterally enlarged thyroid, warm dry skin, heart palpitations, nervousness, prone to thyroid storm
|
What is toxic adenoma
Activating mutations in TSH receptor or its associated G protein i.e. Gs alpha subunit mutation
|
What is papillary carcinoma
psammoma bodies, ground glass "orphan annie eye" nucleus, fibrovascular stalk
|
What is iodine replacement via diet or supplement
Iodine Deficiency Treatment
|
What is HT:: High TSH, low T4/T3, increases TRH, stimulates prolactin --> amennorhea via feedback inhibition. Cushing's --> neg feedback disrupt GnRH
Compare and contrast reason for amenorrhea in hypothyroidism vs. Cushing's disease
|
What is Iodine Deficiency
bilaterally enlarged thyroid, gradual decline in mental function, gradual onset of fatigue, cold intolerant, overweight, constipation, dyspnea
|
What is thyroid stimulating immunoglobulin, binds to TSH receptor and mimics TSH action
Graves disease
|
What is graves' disease
diffuse hypertrophy and hyperplasia, tall and crowded follicular cells, pale colloid with scalloped margins
|
What is radioactive iodine therapy, methimazole, propylthiouracil, beta blockers, thyroidectomy
Graves Disease Treatment
|
What is FAS binds FAS-L, --> DISC (death inducing signalling complex) - includes FADD, --> caspase 8, -->caspase 3 and BID. (extrinsic)
Death pathway experienced by thyroid cells in hashimoto thyroiditis
|
What is functional thyroid adenoma
unilateral swelling of the thyroid - solitary nodule, hot on RAIU, weight loss, hot flashes, heart palpitations, nervousness
|
What is hashimoto thyroiditis
loss of self-tolerance to thyroid auto-antigens, increased T-cell activity and inflammatory response
|
What is hemorrhagic adrenals, presenting with hypotension and DIC secondary to N. meningitis
Waterhouse-Friderichsen
|
What is hashimoto thyroiditis
decreased T3/T4, increased TSH, elevated WBC and inflammatory markers
|
What is labs: hypocalcemia, increased calcitonin Mutation: RET activation
Familial Medullary Thyroid Carcinoma: lab levels? mutation?
|
What is Hashimoto Thyroiditis
An older female, diffusely enlarged thyroid, cold on RAIU, decline in mental function, weight gain, fatigue, constipation
|
What is issue with: iodine transport into cell, moves basal to apical movement, oxidized by peroxidase, combined with thyroglobulin - forms MIT/DIT
Iodine Deficiency
|
What is Hashimoto Thyroiditis (Hurthle cells = metaplastic response to inflammation)
lymphocytic invasion, extensive mononuclear infiltrate, Hurthle cells
|
What is toxic adenoma
high T3/T4, low TSH
|
What is hyperaldosteronemia - Conn's syndrome - via adrenal hyperplasia (17-OH deficiency), adenoma
hypertension, hypernatremia, hypokalemia, alkalosis, low renin
|
What is Cushing's Disease
weight gain, buffalo hump, abdominal striae, high blood pressure, hyperglycemia, fatigue, oligomenorrhea
|
What is MEN 1 --> parathyroid, pituitary, and pancreatic endocrine tumors
mutation in menin, increased calcitonin, hyperparathyroidism, Zollinger-Ellison syndrome
|
What is toxic adenoma
well-circumscribed mass with capsule demarcated from adjacent parenchyma, uniform follicles, homogeneous follicular cells
|
What is when in acute need - i.e. surgery - T4 takes 6 weeks to show improvement, T3 takes only 2.
When would you give T3 as opposed to T4
|
What is pituitary adenoma
dexamethasone test - fail single, fail low, pass high
|
