Atrial Natriuretic Peptide
Term
Primary Hyperaldosteronism
Definition
(Conn’s Syndrome


Caused by adrenal tumors
Causes hypertension and edema due to Na
Causes accelerated loss of K
Term
Secondary Hyperaldosteronisn is caused by?
Definition
renal artery stenosis
Term
Diagnosis of Hyperaldosteronism?
Definition
Test blood for plasma aldosterone concentration (PAC) and plasma renin activity (PRA)

Saline Suppression Test
If aldosterone levels are increased, its primary
If renin levels are increased, its secondary
Term
Treatment of Hyperaldosteronism
Definition
Surgery, or spironolactone to suppress aldo.
Term
Congenital Adrenal Hyperplasia
Definition
Involves enzyme deficiencies (21-hydroxylase)
21-hydroxylase allows steroid production

ACTH is high (in vain), but stimulates androgen production
Term
Effects of
Congenital Adrenal Hyperplasia
Definition
Salt-wasting with vomiting due to lack of aldosterone
Virilization , acne, oligomenorrhea due to increased androgen production (women only)
Stunted growth due to closing of long bone epiphyseal plates
Term
Treatment of Congenital Adrenal Hyperplasia
Definition
Sex Assignment (if necessary)
Hormone supplementation
Androgen Suppression in females
Growth management
Term
Diagnosis of Phenochromocytoma
Definition
24 hr urine catecholamines
Plasma free metanephrines
Localized by MRI or CT
Term
Phenochromocytoma Treatment
Definition
Alpha and beta blockade until surgery
Term
Too little Aldosterone and Too little Cortisol is?
Definition
Addison Disease
Term
Too much Catecholamines is
Definition
– Pheochromocytoma
Term
most common cause of death in children and adolescents with Type 1 DM
Definition
DKA
affects both type 1 and 2
generally acute in onset
Term
Risk factors for DKA
Definition
Infections!!!!!!
discontinue insulin therapy
Unknown primary diagnosis of DM
Medications
eating disorder
active cocaine use
Myocardial infarction
Cerebrovascular accident
Term
Hyperosmolar Hyperglycemic State (HHS)
Definition
Hyperglycemia is associated with a severe inflammatory state
All parameters return to normal within 24 hours of insulin and hydration therapy
Endogenous insulin is secreted
Inadequate to overcome insulin insensitivity in tissues
Adequate to prevent lipolysis and subsequent ketogenesis
Onset over days to weeks
Term
Risk factors for HHS
Definition
Infection
Dehydration or Volume Contraction
Inadequate source
Reduced thirst response in the elderly
Unknown primary diagnosis of DM
Medications: corticosteroids, diuretics, pentamidine, IV medications mixed with dextrose, atypical antipsychotics
Term
Risk factors for HHS
Definition
Infection
Dehydration or Volume Contraction
Inadequate source
Reduced thirst response in the elderly
Unknown primary diagnosis of DM
Medications: corticosteroids, diuretics, pentamidine, IV medications mixed with dextrose, atypical antipsychotics
Term
Anion gap >10-12 indicated increased ?
Definition
metabolic acidosis
Term
Treatment Targets in DKA and HHS
Definition
Correction of dehydration or volume contraction
Correction of hyperglycemia

so if you have K of < 3.3 you have to correct this before correcting sugar
Correction of electrolyte imbalance
Identification and correction of precipitating event(s)
Term
Direct positive correlation between osmolality and mental obtundation.

The lower the osmolality
Definition
the worse the patient is
Term
Direct positive correlation between osmolality and mental obtundation.

The lower the osmolality
Definition
the worse the patient is
Term
Only use Bicarbonate in DKA when pH is
Definition
SEVERE acidosis (pH < 6.9) and mental status changes
ICU monitoring
Term
Correction of target of Glucose in DKA
Definition
Treatment targeted to serum glucose <250 and ketoacidosis
pH >7.30, bicarb >18, gap <12 mEq/L
Once the serum glucose is <200, 5% dextrose should be added to IVF


Hyperglycemia is corrected faster than ketoacidosis
Term
Name 3 diabetic emergencies
Definition
DKA, HHS and Hypoglycemia are Emergencies

Correct what is going to kill the patient first
You need water
You need sugar
You need a heart (functioning properly)
Term
If you suspect Hypoglycemia what should you do
Definition
give glucose

Then find the underlying cause and correct
Reactive hypoglycemia can be treated with acarbose
Sulfonylurea induced: octreotide or 50% dextrose
Ketosis/starvation: high carb diet
Term
Symptoms


Sweating
Nervousness or shakes
Fatigue
Hunger
Tachycardia
Mental status changes or confusion
Definition
Hypoglycemia
