Treat Raynaud's with vasodilators (CCBs and prostacyclin)
364
Presentation of acromegaly/gigantism
Sweating, visual defects. macroglossia, and bony enlargement - gigantism presents with excess height since growth plates are not closed
365
Diagnosis and management of acromegaly/gigantism
Labs and imaging
GH test 2 hour after glucose load
Increased IGF-1
MRI/CT shows a pituitary tumor
Treatment: Pituitary tumor removal
366
Etiology of Addisons disease
MCC - Autoimmune
Can also be brought on by TB
367
Presentation of addisons disease
Hyperpigmentation, hypotension, fatigue, myalgias, GI complaints, weight loss
Due to reduction in cortisol
368
Diagnosis of addisons disease
↓ sodium, ↓ 8 AM cortisol, ↑ ACTH (primary), ↑ potassium (primary), low DHEA
High dose cosyntropin (synthetic ACTH) stimulation test
Blood or urine cortisol is measured after an IM injection of cosyntropin (synthetic ACTH)
The normal response is a rise in blood and urine cortisol levels after synthetic ACTH is given
Primary adrenal insufficiency results in little or no increase in cortisol levels (< 20 mcg/dL) after ACTH is given
369
Management of addisons disease and addisonian crisis
Hydrocortisone/prednisone PO daily
Crisis: Hypotension, altered mental status
Treatment: Emergent IV saline, glucose, steroids
370
Cushing syndrome v disease
Syndrome - nonspecific source
Disease - pituitary adenoma
371
Presentation of cushing disease
obesity (buffalo hump, moon facies, supraclavicular pads), HTN, thirst, polyuria, hypokalemia
Proximal muscle weakness, pigmented striae; backache, headache, oligomenorrhea/amenorrhea / ED; emotional lability/psychosis
Due to excess cortisol
372
Diagnosis of cushing disease
24 hr urine free cortisol, late-night serum cortisol, and/or low-dose dexamethasone suppression test
High ACTH = pituitary adenoma likely
Low ACTH = Non-pituitary etiology likely
373
Dexamethsone suppression test
Give a steroid (dexamethasone) ⇒ failure of steroid to decrease cortisol levels is diagnostic ⇒ proceed next to high dose dexamethasone suppression test ⇒ no suppression = Cushing's syndrome
Suppression < 5 ugs/dL excludes Cushing with some certainty
374
Managment of cushing disease
transsphenoidal selective resection of pituitary tumor cures 75-90%
Irradiation provides remission in 50-60%
95% 5-year survival
375
Causes of central diabetes insipidus
Idiopathic, autoimmune destruction of posterior pituitary from head trauma, brain tumor, infection, or sarcoidosis
376
Causes of nephrogenic diabetes insipidus
Drugs (Lithium, Amphoterrible), hypercalcemia and hypokalemia affect the kidney's ability to concentrate urine, acute tubular necrosis
377
Diagnosis of diabetes insipidus
Serum osmolality is high while urine osmolality is low
No response to fluid restriction (not psychogenic)
No response to desmopressin (nephrogenic as opposed to central)
378
Management of central and nephrogenic diabetes insipidus
Central = desmopressin/DDAVP
Nephrogenic = sodium and protein restriction, HCTZ, indomethacin

3+ of five criteria
Fasting TG over 150
HDL under 40
BP over 130/85

Waist circumference over 40(M) 35(F)
If they are on meds for any of these conditions that counts
384
Insulin effect on sdium, blood vessels and lipolysis
Retains sodium, dilates blood vessels, leads to FFAs in blood stream
In insulin resistance it still retains sodium but DOES NOT dilate blood vessels

Management of DKA
TREAT WITH FLUIDS! Patients with DKA are always dehydrated and need large-volume IV fluid resuscitation, usually isotonic fluids such as normal saline. If the corrected serum sodium level is high, this can be reduced to half-normal saline. Insulin should always be administered by an IV pump to guard against accidental overdose.
