Thompson 1 Flashcards
1
Q
What glucose issure can be present in up to 20% of those with Conns?
What acid base issue may they have
A
- Glucose issue = glucose intolerance
- Acid base issue = metabolic alcolosis
2
Q
Epinephrine vs norepinephrine
A
- epi = fight or flight, increases HR, BP, dilates pupils, redirects blood to muscles
- Norepinephrine = increases BP
3
Q
what does cortisol do
A
- regualtes BP, cardiac function, immune system, mood, insulin metaboism
4
Q
what does aldosterone do
A
- BP
- water balance
Na balance
- helps kidney keep Na and get rid of K+
5
Q
Pheocrhomocytoma
A
- Growth on the adrenal leads to increased production of Epi and NE
- Called 10% tumor
–> malignant (10% of time)
–> 2 sided (10% of time) etc, in kids, familial, recur
- SYMPTOMS = Rapid HR, high BP, flushed, anxiety, pale (increased fight or flight)
- TX = surgical removal
6
Q
POTS –> type of autonomic failure
A
- Postural orthostatic tachycardiac syndomre = a combo of symptoms from variety of causes (viral, CA, adrenals)
- Faiting, CP, SOB, fatigue
- Orthostatic hypotension (lots of passing out)
- Meds to treat symptoms
7
Q
ADDISONS DISEASE
A
- Failure of adrenals to make enough cortisol (sometimes aldosterone too)
- Lach of ACTH –> pituitary dysfunction (secondary)
–> keep making aldosterone
- Lack of adrenal function/response (primary)
- SYmptoms = wt loss/decreased appetite, fatigue, low BP, darkening of skin, darkening around teeth
- LOW GLU, LOW Na AND HIGH K
- Not enough cortisol and pts gets sick –> can be fatal
- TX = STEROIDS (inrease during stress, surgery, illness)
–> STRESS DOSE GIVEN WHEN BODY WILL BE STRESSED
8
Q
CUSHINGS
A
- opposite of addisions (too much steroids) too much ACTH
- Symptoms = trunk obesisty, buffalo hump, HYPERTENSION, Hyperglycema, hypernatremia, hypokalemia, moon face, purple stretch marks, easy fractures
- long term = obesity, osteoporosis, diabetes, muscle weakness, skin issues
- Cause = Iatrogenic (steroid use), etc
- TX = taper steroids, surgery to remove tumors, signifor (reduce cortisol)
*** LIKE ADDISONS, CURSHINGS MAY REQUIRE STRESS DOSING OF STEROIDS DURING ILLNESSES, PRIOR TO SURGERY, ETC
9
Q
CONN’S DISEASE (HYPERALDOSTERONISM)
A
- overproduction of aldosterone (benign tumor usual, bilateral adrenal hyperplasia)
- TX = take out adrenal or spiranolactone (blocks aldosterone)
- SYMP: HYPERTENSION, LOW K, Headache, MUSCLE WEAKNESS
- SUSPECT HYPERALDOSTERONISM IN PT WITH RESISTANT HTN and LOW POTASSIUM
