Incorrects 6 Flashcards
Proper Dx and Rx for Premenstrual syndrome and premenstrual dysphoria disorder?

Rx: SSRI. Combined OCs can also help by preventing ovulation.
What medication can lead to hypercalcemia with high/high-normal PTH?
Lithium.

Expected urine sodium levels in SIADH?
> 40mEq/L usually. This would be in the presence of concentrated urine.
What odd renal effect can SSRIs cause in the elderly especially?
SIADH.
In hyponatremia due to polydipsia or low solute intake, what is the urine osmolality?
Appropriately low (<100mOsm/kg H2O). The kidneys are not damaged and retain capacity to dilute urine unlike SIADH.
Colorectal cancer, endometrial cancer, and ovarian cancer are classic for what syndrome?
Lynch syndrome. aka Hereditary nonpolyposis colorectal cancer
Hemangioblastoma, renal cell carcinoma, pheochromocytoma and pancreatic neuroendocrine tumors are class for what syndrome?
Von Hippel-Lindaue disease.

Milk-alkali syndrome (usually calcium carbonate).
When to give the PCV13?
Anyone over 65 (followed by PPSV23 later);
High risk patients under 65 (CSF leaks/cochelar implants, sickle cell, aslpenia, immunocomp, CKD).
Who gets PPSV23 alone?
Anyone age 19-64yo.

As a one time booster to replace any 10 year booster later on OR pregnant women OR anyone coming into contact with children
What exposure leads to clear cell adenocarcinoma of the vagina?
Diethylstilbestrol (DES) in utero.
First testing required when Raynaud’s occurs?
ANA, RF, ESR, complement. Raynaud’s is associated with many connective tissue diseases (SLE, scleroderma, thromboangiitis obliterans). Primary Raynaud’s is NOT associated with connective tissue disease (negative ANA, RF, ESR).
MCC of neonatal sepsis?
Group B Strep. This presents within 7 days of vaginal birth. If mom is GBS+ and a C sxn occurs, sepsis within 7 days may be due to mother passing it via her hands. This is still more likely than Listeria.
Sx of Listeria?

Pagets disease of bone.
An elevated calcium and PSA over what level is suspicious for?
Metastatic prostate cancer.
What occurs after suction D&C of hydatidiform mole?
ß-hCG levels are followed weekly until undetectable. This is important because a plateau or increase in ß-hCG is diagnostic of geestational trophoblastic neoplasia (GTN) (eg choriocarcinoma). ß-hCG is followed for 6 months after undetectable. If it rises, that is likely GTN. Contraception should be prescribed during this time.
CA-125 is a tumor marker for what cancer?
Epithelial ovarian cancer.
Why is aldosterone unaffected in central adrenal insufficiency?
The adrenal glands are intact and respond to the RAS for aldosterone secretion.
Why is aldosterone reduced in primary adrenal insufficiency?
The adrenal glands are damaged and aldosterone secretion is affected. Hyperkalemia and hyponatremia with low BP is a feature due to hypoaldosteronism. Elevated ACTH secretion also causes hyperpigmentation.
How can age related dry eyes (age related sicca syndrome) and Sjögren syndrome be differentiated?
Though Sx are almost identical, Sjögrens shows up in middle age, not after 65, and most have a positive ANA. If there are systemic Sx, then it is probably secondary to systemic sclerosis.
What is focal nodular hyperplasia?
A benign solid liver mass made up of arteries commonly found in women.
Hepatic adenoma is associated with?
Long term OCs in women. It may hemorrhage or transform, but rarely.
Hepatocellular carcinoma lab marker?

Main RF for cholangiocarcinoma?
PSC.
What form of CBT is used in Tourette’s?
Habit reversal training
Enlargement of what leads to atrial fibrillation?
Either of the atria. This can be due to valvular problems (eg RH leading to MS).
Required testing in amaurosis fugax?
Carotid US. Carotid atherosclerosis is the most common site of emboli formation due to plaque. Emboli from the heart causing amaurosis fugax is rare and echo is rarely needed.

Multiple sclerosis. Do LP and CSF analysis (oligoclonal bands).
What are the first 3 factors considered in a Pt with low corrected calcium before checking PTH?
Low magnesium? Recent blood transfusion (high citrate)? Is it due to a drug?
Pathophys behind low calcium in hypomagnesemia?
Low magnesium can cause PTH resistance to low Ca++.
How much is serum Ca++ reduced for each 1gm/L albumin decrease in the blood?
Ca++ decreases by 0.8 per every gram of albumin reduced in the blood.
What other electrolyte is expected to coexist with hypomagnesemia in alcoholics?
Hypophosphatemia.
When should antivirals be administered for influenza infxn?
Those with RFs (≥65yo, pregnancy, chronic medical conditions) for influenza complications should get antivirals (oseltamivir) anyway. Or those w/o RFS who are <48hrs from start of Sx.
If a patient with new HIV refuses to tell their partner, what is the next step?
The doctor must report to the local health department within 48hrs any new STD Dx (eg HIV). They will tell the husband.
Abnormal dilations within the nail fold capillaries on nail fold microscopy in a man over 40 with Raynaud’s may signify what disease?
