IM ENDO Flashcards
Conn syndrome is…
best screening test
1ry hypoaldestorenism
ald / renin ratio
subacute thyroiditis - iodine uptake / treatment
decreased
treatment: NSAID, b blockers, steroids if refractory
medications associated with gynecomastia
- spironoloactone
- cimetidine
- 5a reductase inhb
- ketoconazole
Chronic adrenal insuf - presentation
Low Na, high K, hyperchl met acidosis
increased pigmentation
sulfolynurea poisoning - managment
dextrose + octreotide (somatostatin analogue –> decreases insulin secr)
subclinical hypothyrodism - treat if
- antithyroid abs
- lipid abnormalities
- symptoms
- ovulatory or mens dysfunction
- TSH > than 10 or 7-10 and younger than 70
start statin if
- LDL more than 190
- Older than 40 + DM
- known athero CV risk
suspect diabetic neuropathy - next step
turning fork test
diabetic neuropathy - management
aggressive glycemic control
if still in pain TCA, SNRIs (duloxetine) or anticonvulsants like Gabapentin or pregabalin
maybe also topical treatments (lidocane etc)
NOT SSRIs
thryroid nodule - FIRST STEP
Clinical evaluation, TSH + U/S
thryroid nodule - with cancer suspicion (after U/S) –>
FNA
thryroid nodule - low cancer risk –>
Normal or elevated TSH –> FNA
Low TSH –> iodine scintigraphy –> if hot treat hyper, if cold or interm cold do FNA
MEN type 1
- PTH
- pancreatic tumor
- pituitary
MEN type 2A
- PTH
- Pheo
- Medullary Thyroid
MEN type 2B
- Medullary Thyroid
- Pheo
- mucosal + interstitial neuromas
- Marphanoid habitus
Medullary thyroid carcinoma diagnosis - next step
serum calcitonin, CEA, neck US (mets), genetic test for RET, evaluation for coexisting tumors (esp PCC) –> Then surgery
Medullary thyroid carcinoma - before surgery rule out
pheochromocytoma
subclinical hyperth - treat if
- persistent TSH below 0.1
- TSH between 0.1-0.5 +
- age >65
- heart disease
- osteoporosis
- nodular thryoid disease
anabolic steroid abuse -effect in hematology
erythorcytosis
anabolic steroid abuse -effect in LIPIDS
HIGH LDL / LOW HDL
anabolic steroid abuse -effect in sex
normal libido + erectile during use
low libido + impotence during withdrawal
rare but serious complication of metformin
lactic acidosis (increased risk with hypovolemia, liver / kidney / heart disease_
Treat megalob anemia with B12 - MONITOR ….
K levels (risk of hypo)
Hyperthyr with cardiov symptoms - initial treatment
b-blockers
hypercalcemia - next step
measure PTH
- elevated (PTH depended)
- low indipended –> see PTHrp and vitd
PTH depended hypercalcemia - causes
primary
familiar
lithium
PTH independed hypercalcemia - causes
- malignancy
- vit D
- drugs
- granuloatous
diuretic to increase serum CA2+
thiazides
treatment of chronic hypoparathyroidism
- Vitamin D (over calcitriol the active form because cheaper)
- Ca2+
- thiazide (if low serum and high urine
hypoglycemia associated autonomic failure - presentation
- reduced neurogenic hypoglycemic symptoms (tremor sweeting etc)
- increased risk for neuroglycopenic (confusion, LOC)
hypoglycemia associated autonomic failure - RF
- long-standing DM1
2. recurrent or severe hypoglycemia
hypoglycemia associated autonomic failure - management
- avoid hypoglycemia
- reduce insulin dose
- less strict glycemic targets
