Endocrine, Nutrition and GI Pathologies Flashcards
Gigantism vs Acromegaly
Gigantism: excess GH <18 yrs, pituitary adenoma, overgrowth of tissues in body (large hands, protruding jaw), headache, visual disturbance
Acromegaly: excess GH >growth plates closed, protruding jaw, large spatulae hands, large feet, headache, visual disturbance
Cushing’s Disease vs Syndrome
Disease: excess ACTH, from functioning pituitary adenoma, excess cortisol –> moon-face, buffalo hump, truncal obesity, HTN, purple striae, hyperpigmented sin creases, muscle wasting in extremities (recurrent infxn)
Syndrome: exogenous stroids or tumor, truncal obesity, moon face, buffalo hump, HTN, HYPERGLYCEMIA, poor wound healing, purple striae, NO HYPERPIGMENTATION
GH deficiency in children? Symptoms?
Pituitary dwarfism growth retardation (non-functioning pituitary tumor)
Ischemic necrosis of anterior pituitary lobe? Cause? S/S?
Sheehan’s syndrome
Severe postpartum hemorrhage
Amenorrhea, cessation of lactation, loss of axillary/pubic hair
Hyperprolactinemia cause and S/S
Secreting prolactin pituitary adenoma
Galactorrhea, amenorrhea, infertility
ADH deficiency from head injury, pituitary tumors, kidney disease, sarcoidosis and S/S?
Diabetes insipidus
polyuria, polydypsia, SpG urine <1.010 (despite hydration)
Hypothyroidism in adults vs infants
1o?
2o?
Reidel’s?
Myxeedema and cretinism
1o: Low T3/4 HIGH TSH, fatigue, constipation, brittle hair, slow to relax reflexes, weight gain
like in Hashimoto’s (anti-thyroglobulin Ab and goiter)
2o: low T3/4 and TSH, pituitary hypofunctioning
Reidel’s: lymphocytic fibrotic thyroid disease leading to hypothyroidism
Hyperthyroidism:
1o? Graves? Plummer’s?
2o?
1o: elevated T3/4 LOW TSH
Graves: MC, IgG ab bind to TSH receptors, exopthalmos, goiter, fine tremors of hands, nervous, diarrhea, weight los (increased appetite) HLA-B8
Plummer: toxic multinodular goiter, no exopthalmos
2o: inc T3/4 TSH - TSH secreting pituitary tumor
Hyper vs hypoparathyroidism:
Hyper: functioning parathyroid adenoma, hypercalcemia, acro-osteolysis, brown bone cysts (decomposed blood and hemosiderin)
Hypo: incidental removal of parathyroid,hypocalcemia, tetany and muscle twitching, Chvostek test + (tap facial N by ear)
Autoimmune or TB related chronic underfunctioning of adrenal cortex - S/S
Addison’s disease
low cortisol/aldosterone, hyperpigmented skin creases, bronze skin, low Na, BP but high K and ACTH
Waterhouse-Friedrichsen syndrome - cause and S/S?
acute adrenal bleeding, 2o to N. meningitidis septicemia
Shock, hemorrhagic rash
Overfunctioning of zona glomerulosa results in? Due to? S/S?
Conn’s disease
Adrenal adenoma, excess mineralocorticoids
low potassium, renin, metabolic alkalosis, high BP
Deficiency in 21-hydroxylase enzyme leads to?
Congenital adrenal hyperplasia/Adrenogenital syndrome
Excess androgen production, virilization of female infant
Neuroblastoma and oncogene
MC adrenal medulla tumor in kids, M-MYC oncogene
Diabetes Type I vs II all you can list… GO!
I: insulin dependent, beta cell destruction, Ab to beta cells of pancreas, weight loss, Diabetic Ketoacoidosis, children, teens, HLA-DR34
II: non-insulin dependent, insulin receptor insensitivtiy, insulin levels elevated, obese adults, fm hx, polyuria, polydypsia, polyphagia, hyperosmolar non-ketotic coma (dehydration), advanced glycated end products, narrowing of small/med sized vessels, damage vasa vasora and nervosa, premature cataracts and retinopathy related to acc of sorbitol
Mature Onset Diabetes in the Young
Non-insulin dependent, no islet cell ab, not obese, <25
Gestational diabetes
3-10% all pregnancies, resolves w/end of pregnancy, 50% develop T2DM w/in 15 yrs
Carcinoid syndrome what cells? S/S?
Neuroendocrine in gut
recurrent diarrhea, cutaneous flushing, bronchial wheezing
(1/3 mets, 1/3 multiple)
Insulinoma. Relieved by?
Pancreatic beta-islet cell tumor
Hypoglycemia relieved by food
Gastrinoma cause, S/S?
excess gastrin from GI tumor
Recurrent peptic ulcer disease (Zollinger-Ellison syndrome)
Part of MEN type I
MEN Type 1
2a? 2b?
1: Wermer’s syndrome, pituitary adenoma, parathyroid adenoma, pancreas adenoma
2a: Sipple’s syndrome: medullary thyroid cancer, pheochromocytoma, parathyroid hyperplasia
2b: Marfanoid ft, medullary thyroid CA, mucosal neuromas, pheochromocytoma
Failure of lower esophageal sphincter to relax; loss of ganglion cells (myenteric plexus)
Achalasia - mainly dysphagia for liquids
Hiatal hernia
stomach into chest through diaphragm
Dilated V in lower esophagus (portal HTN)
Esophageal varices
