Abnormal menstrual bleeding (no bleeding or spotting in between periods)
Inability to conceive
Is there a definitive test for diagnosing PCOS?
No, it is a diagnosis of exclusion
What are some treatment options for PCOS?
Suppress insulin-facilitated, luteinizing hormone androgen production
Oral contraceptives
Provera (restore menstrual cycle)

What is commonly seen in children with a vitamin D deficiency?
Rickets (bowing of the legs)
What is the treatment for patients with a vitamin D deficiency?
2000 IU vitamin D2 or D3 per day x 6 weeks
50,000 IU vitamin D2 per week x 6 weeks
Maintenance dose = 600-100 IU/daily
10-15 mins mid day sun exposure 1-3 times per week
A patient presents with some or all of the following complaints, what is your suspected diagnosis? And how do you treat it?
Bone pain, kidney stones , abdominal pain and N/V, frequent urination, and confusion
Vitamin D toxicity (bones, stones, groans, thrones, and psychiatric overtones)
Treat w/IV fluids, loop diuretics, bisphosphonates
What is the treatment for a vitamin K deficiency?
Fresh frozen plasma
What vitamin deficiency is more commonly seen in alcohol use disorder?
B1 (thiamine)
What is the difference between “wet” and “dry” beriberi?
Wet: affects cardiovascular system (high output heart failure 2/2 vasodilation & AV fistulas)
Dry: affects CNS (think Wernicke or Korsakoff) (peripheral neuropathy, ataxia, AMS, memory loss, confabulation)
What treatment helps prevent peripheral neuropathy in a patient with a vitamin B6 (pyridoxine) deficiency?
Isoniazid
What is the treatment for a vitamin B12 deficiency?

Maintenance dose: 1000 mcg/day
What can present with sore lips & tongue, nausea, diarrhea, anorexia, weight loss, cognitive dysfunction, dementia, and/or depression?
Folate deficiency
What labs are indicative of DM I?
A1c >6.5, fasting glucose >126 or any glucose >200
The primary treatment option for DM I is what?
Insulin
What are different types/dosing of insulin?
Long acting injection (detemir/glargine): 10 units/day starting dose, increase 2-4 units until glucose goal met, decrease 4 units in hypoglycemia
Short acting injection (Humulin R/Novolin R): when glucose goal met but A1c high, 4 units single dose, non-fasting glucose above goal increase dose 1-2 units, hypoglycemic decrease 2-4 units
Pre-mixed insulin (Humulin [70/30], Novolin [70/30]): 2x/day when glucose at goal, but A1c above goal
Rapid acting (aspart/lispro): 4 units single dose before largest meal of day
What are important assessments/screenings to perform in patients with DM I?
Check A1c every 3 months until controlled, then every 6 months (goal is <7% if life expectancy >10yrs)
Screenings for: retinopathy (annual), HTN (each visit), hyperlipidemia (annual), CKD (annual) microalbumin/creatinine ratio in addition to BMP or CMP (every 3-6 months), neuropathy (annual), PVD (each visit)
What are signs/symptoms of DKA?
Blood glucose >250mg/dL
Symptoms of hyperglycemia
Decreased pH <7.3
Decreased bicarb <10mEq/L
Anion gap >12
Ketonuria
Fruity breath
Kussmaul resp.
AMS
Shock
How do you treat DKA?
ICU admission
TX goals to correct:
dehydration, hyperglycemia, electrolyte imbalance (K+), acid-base imbalance, underlying trigger (infection, missed dose)
Do NOT typically aim for normalization of blood sugar
Fluids and insulin (w/i 1 hr at IV infusion rate of 0.1 units/kg/hr)
What are 1st and 2nd line pharm treatments for DM II?
Metformin (1st line)
Insulin secretagogues (2nd line) (Sulfonylureas - Glipizide, glimepiride) (Meglitinides - Prandin, Starlix)
