This herpesvirus is implicated in nasopharyngeal carcinoma and certain forms of lymphoma
Epstein-Barr Virus (EBV)
This class/dose of medication is recommended in all patients age >21 with LDL >190
High intensity statin
e.g atorvastatin 40-80 mg; rosuvastatin 20-40 mg
This acute MI mimicker that occurs predominantly in older women who may have normal coronary arteries but an abnormal echocardiogram
Takotsubo cardiomyopathy (stress cardiomyopathy)
A renal artery 'string of beads' radiographic sign is associated with this disorder
Fibromuscular dysplasia
This is the test of choice to screen for acromegaly
IGF-1 (insulin-like growth factor 1)
This scoring is system used to predict ADAMTS13 deficiency in suspected thrombotic thrombocytopenic purpura
What is the PLASMIC score
This is a positive screening test for primary hyperaldosteronism
Suppressed renin is typical finding in primary hyperaldo. Aldo also usually >10ng/dL but consider further eval if renin is suppressed
This is the formula for calculating mean arterial pressure.
([Diastolic BP x 2] + Systolic BP) / 3
This condition is characterized by a decrease in urinary concentrating ability from resistance to antidiuretic hormone
Nephrogenic diabetes insipidus (need nephrogenic!)
Most likely cause of primary amenorrhea, lack of secondary sexual characteristics, webbed neck, and short stature
Turner syndrome
This inborn error of metabolism precludes use of rasburicase
Glucose-6-phosphate dehydrogenase deficiency
This is the LDL goal for a patient age 40-75 with diabetes and established atherosclerotic disease
What is <55
This restrictive cardiomyopathy has a 'speckled pattern' in echocardiogram
Cardiac amyloidosis
These types of renal tubular acidosis are associated with hypokalemia
Type 1 (distal) and type 2 (proximal)

This condition is associated with GAD65 and IA-2 autoantibodies
Type 1 diabetes / Latent autoimmune diabetes of adulthood
This lipid abnormality is used as diagnostic criteria for hemophagocytic lymphohistiocytosis
Hypertriglyceridemia
When comparing HCTZ and Chlorthalidone, this agent had more hypokalemia, hyponatremia in the LEGEND-HTN trial
Chlorthalidone
(*note they had no difference in CV outcomes)
This is the most common objective finding of Lyme carditis
Atrioventricular conduction block (accept AV nodal block or AV block)
This alcohol toxicity is associated with normal anion gap and elevated osmolar gap
Isopropyl alcohol
Isopropyl alcohol, while technically not a toxic alcohol, can cause morbidity and mortality and is more commonly ingested than the toxic alcohols. Isopropyl alcohol poisoning presents similarly to ethanol poisoning only more severely with coma and cerebellar signs, and it has more of a predilection for hemorrhagic gastritis and pancreatitis. Don’t ignore abdominal complaints in patients with a history of alcohol misuse!
Isopropyl alcohol is about twice as inebriating as is ethanol (for any particular load or blood level) and lasts twice as long.
This rare complication of anti-thyroid drugs presents as fever in 92% of cases.
Agranulocytosis
This complement-mediated red blood cell destruction is diagnosed by absence of CD55 and CD59 on flow cytometry
What is paroxysmal nocturnal hemoglobinuria
The 6 reasons that the 2025 hypertension guidelines suggest screening for primary hyperaldosteronism if present
What is
1. resistant HTN, 2. Hypokalemia, 3. OSA, 4. adrenal mass, 5. FH of early HTN, 6. CVA <40yo
These are two cardiac valves in which regurgitation can cause a pulsatile liver
Tricuspid and aortic
These serum sodium, urine osm, and urine specific gravity findings are associated with beer potomania
Hyponatremia
Osm < 100
Urine spec grav low

Fun fact: urine osmolality measures exact # of dissolved particles, spec grav is weight of volume of urine (indirect measure of density of particles).
This drug class is used to treat amiodarone-induced thyroiditis type II, or destructive thyroiditis
Glucocorticoids
