AAW - Endo/Repro Flashcards
1
Q
carcinoid syndrome
A
Rare syndrome caused by carcinoid tumors
(neuroendocrine cells), especially metastatic
small bowel tumors, which secrete high levels
of serotonin (5-HT). Not seen if tumor is
limited to GI tract (5-HT undergoes first-pass
metabolism in liver). Results in recurrent
diarrhea, cutaneous flushing, asthmatic
wheezing, and right-sided valvular disease.
increased 5-hydroxyindoleacetic acid (5-HIAA) in
urine, niacin deficiency (pellagra).
Treatment: resection, somatostatin analog (e.g.,
octreotide).
2
Q
Every now and then, I get really flushed for about 5 minutes and then it goes away and I don’t know what it is!
A
think carcinoid syndrome
carcinoid tumors now called neuroendocrine tumors i guess
3
Q
diagnostic test for carcinoid syndrome
A
5-hydroxyindolacetic acid in urine
4
Q
salt and pepper chromatic pattern with oval nucleus
A
neuroendocrine tumor
5
Q
Adrenal hemorrhage, hypotension, DIC
what syndrome
what bacteria
A
waterhouse-friederichsen syndrome
Acute 1° adrenal insufficiency due to adrenal hemorrhage associated with Neisseria meningitidis
septicemia, DIC, and endotoxic shock.
6
Q
exophthalmos, weight loss, palpitations
what is it
how do you diagnose
A
graves disease - type II hypersensitivity
Most common cause of hyperthyroidism. Autoantibodies (IgG) stimulate TSH receptors on thyroid
(hyperthyroidism, diffuse goiter), retro-orbital fibroblasts (exophthalmos: proptosis, extraocular
muscle swelling B ), and dermal fibroblasts (pretibial myxedema). Often presents during stress
(e.g., childbirth).
ELIZA to look for those antibodies
7
Q
cervical dysplasia and cacinoma in sity assc with what virus
what are the genetic effects of the virus
A
HPV 16 and 18, which produce both the E6 gene product
(inhibits p53 suppressor gene) and E7 gene
product (inhibits RB suppressor gene)
p53 normally recruits bax, which knocks out BCL-2 (the molecule that normally stabilizes the mitochondrial membrane) - if mit memb is bad, cytochrome C leaks out and the cell dies
destruction of Rb stops its inhibition of E2F, which moves cells into S phase

GH receptor antagonist
makes you short as a peg
12
Q

dopamine agonists (bromocriptine or cabergoline) are the Tx for prolactin secreting tumors
13
Q
function of thyroid peroxidase what blocks it (used for what purpose? SE?)
A
oxidizes iodide to iodine in the thyroid, which eventually iodinates thyroglobulin tyrosine residues

SE skin rash, agranulocytosis (rare), aplastic anemia, hepatotox (PTU). Methimazole is a possible teratogen
14

2nd gen: **glipizide**, glimepiride, glyburide (rarely used). SE: hypoglycemia
MECH:
binds to the SUR1 subunit of the K channel, closing it. Happens in the beta cell, depolarizes and triggers insulin release via Ca influx SO IT DOESN'T WORK IF THEY HAVE NO ISLETS LEFT
40
Pramlintide
not common
Amylin analog - makes people feel full - amy and LINT in her pocket - also the TIDE is the fullness feeling
used to decrease gastric emptying, decreases glucagon

(V2-receptor), MSH, PTH
I don't know why these aren't in the mneumonic in FA, but these too:
calcitonin, GHRH,
glucagon
(i guess champs need to tone their bones, need to have a GROWTH HORMONE RELEASING HORMONE, and need to have sugar in their blood to perform like a champ)

found in the interstitium between the seminiferous tubules
57
tunica albuginea
thick capsule around the testis that has septa that divide the different lobules
58
what cells secrete inhibit and what do they do
sertoli cells:
inhibin inhibits FSH directly at the pituitary (the sertoli cells themselves are stimulated by FSH, and increased spermatogenesis when bound by FSH)
also they secrete androgen-binding protein --> maintains local levels of testosterone
tight junctions between adjacent sertoli cells form the blood-testis barrier --> isolate gametes from autoimmune attack
temp sensitive, decrease sperm production and inhibin release when temps go up
59
main energy source for motile sperm
where is it made
fructose
made in the seminal vesicles (seminal fluid is rich in fructose, ascorbic acid, and prostaglandins)
60

can get addison-like hyperpigmentation from the desmolase inhibition
desmolase is what converts cholesterol into pregnenolone (and then all the androgens are downstream of that)
85
amenorrhea/oligomenorrhea, hisrutism, acne, not fertile, obese

common type.
Placenta increta—placenta penetrates into
myometrium.
Placenta percreta—placenta penetrates
(“perforates”) through myometrium and into
uterine serosa (invades entire uterine wall);
can result in placental attachment to rectum
or bladder.

100
how do you differentiate between paget's disease of the vulva and vulvular melanoma
paget: PAS + (mucus - only epithelial cells make mucus), keratin + (intermediate filament present in epithelial cells - if epithelium is malignant its called carcinoma), s100 neg

decreased cortisol
increased sex hormones
decreased K
decreased renin activity (because of increased BP?)
104
triiodothyronine resin uptake test results in a person with hypothyroidism
they are hypothyroid, so they don't have much of their T3 bound to their thyroxine-binding globulin in their serum
so you mix patients serum with radioactive fake T3 and that occupies the empty thyroxine-binding globulin
then put a block of insoluble T3 resin in the serum
you will notice that **the resin has a reduced uptake of fake, radiolabeled T3**, because it is all taken up by the patients empty thyroxine binding globulin
105
what causes elevated levels of PTH in people with kidney failure

Homeobox (HOX) genes
involved in segmental organization of embryo in a craniocaudal diraction. Code for stranscription factors
mutations --> appendages in wrong locations

teratogenic effects of:
ACE inhibitors
Alkylating agents
Aminoglycosides
Antiepileptic drugs
Diethylstilbestrol
Folate antagonists
Isotretinoin
Lithium
Methimazole
Tetracyclines
Thalidomide
Warfarin
ACE inhibitors: Renal damage
Alkylating agents: Absence of digits, multiple anomalies
Aminoglycosides: Ototoxicity A mean guy hit the baby in the ear.
Antiepileptic drugs: Neural tube defects, cardiac defects, cleft
palate, skeletal abnormalities (eg, phalanx/nail
hypoplasia, facial dysmorphism)
High-dose folate supplementation
recommended. Most commonly valproate,
carbamazepine, phenytoin, phenobarbital.
Diethylstilbestrol: Vaginal clear cell adenocarcinoma, congenital Müllerian anomalies
Folate antagonists: Neural tube defects Includes trimethoprim, methotrexate,
antiepileptic drugs.
Isotretinoin: Multiple severe birth defects Contraception mandatory. IsoTERATinoin.
Lithium: Ebstein anomaly (apical displacement of
tricuspid valve)
Methimazole: Aplasia cutis congenita
Tetracyclines: Discolored teeth, inhibited bone growth “Teethracyclines.”
Thalidomide: Limb defects (phocomelia, micromelia—
“flipper” limbs)
Limb defects with “tha-limb-domide.”
Warfarin: Bone deformities, fetal hemorrhage, abortion,
ophthalmologic abnormalities
Do not wage warfare on the baby; keep it heppy
with heparin (does not cross placenta).

mnemonic for branchial pouch derivatives

Ear, tonsils, bottom-to-top:
1 (ear),
2 (tonsils),
3 dorsal (bottom for inferior
parathyroids),
3 ventral (to = thymus),
4 (top = superior
parathyroids).

tolbutamide
first gen sulfonylurea
closes K channel in beta cell, depolarizes it causing insulin release
SE: disulf
147
chlorpropamide
first gen sulfonylurea
closes K channel in beta cell, depolarizes it causing insulin release
148
nateglinide, repaglinide
meglitinides
bind to the same K channels that sulfonylureas to, but in a different area

tuberoinfundibular pathway
dopaminergic pathway
when the activity is decreased (by dopaminergic blockers such as antipsychotics), you get increased prolactin, decreased libido, sexual dysfunction, galactorrhea, gynecomastia (in men)
152
elevated alpha fetoprotein with normal estriol and beta-human chorionic gonadotropin
probably a neural tube defect

phenoxybenzamine (16 letters) is given for
pheochromocytoma (16 letters)

antihistone antibodies
what disease
drug-induced SLE
getting lupus is SHIPP-E
sulfa drugs, hydralazine, isoniazid, phenytoin, procainamide, etanercept

hydralazine
what does it do
mech
increases cGMP, smooth muscle relaxation, vasodilates arterioles more than veins
usually administered with a beta blocker to reduce reflex tachycardia
