A 39-year-old male sees you for evaluation of high blood
pressure. His past medical history is unremarkable. On
examination he has a BMI of 32 kg/m2 and you note that he has
a round face and a plethoric complexion. His blood pressure is
150/98 mm Hg, his pulse rate is 88 beats/min, and his
respiratory rate is 16/min. Other notable findings include a
prominent dorsal cervical fat pad and supraclavicular fat pads,
as well as violaceous striae on his trunk. Laboratory findings are
notable only for a fasting glucose level of 114 mg/dL.Which one
of the following is the most likely cause of his hypertension?
A.Addison's disease

B.Cushing syndrome
C.Hemochromatosis
D.Pheochromocytoma
E.Primary hyperaldosteronism
.....ANSWER.....B
This patient's clinical findings are consistent with Cushing
syndrome, or hyperadrenocorticism. This is a clinical syndrome
and metabolic disorder resulting from chronic excess of
glucocorticoids. The most common cause is corticosteroid use, but
adrenal neoplasms account for 20%-25% of cases. Findings
include general weakness, osteoporosis, moon facies, facial
plethora, ecchymoses, truncal obesity, violaceous striae of the
abdomen, deposition of adipose tissue in the interscapular area
("buffalo hump"), and glucose intolerance.

You diagnose stage 2 hypertension in a 54-year-old male. His
past medical history is otherwise unremarkable and a physical
examination is notable for mild AV nicking on funduscopic
examination. A baseline EKG reveals evidence of left ventricular
hypertrophy.Which one of the following classes of
antihypertensive agents has NOT been shown to produce a
regression of left ventricular hypertrophy?
A.ACE inhibitors
B. β-Blockers
C. Calcium channel blockers
D. Direct vasodilators
E. Thiazide diuretics
.....ANSWER.....D

In patients with left ventricular hypertrophy, studies have shown a
reduction in left ventricular mass in those treated with ACE
inhibitors, diuretics, calcium channel blockers, and β-blockers, with
the most consistent reduction achieved with ACE inhibitors and the
least with β-blockers. Regression of left ventricular hypertrophy
has not been demonstrated with direct vasodilators such as
hydralazine and minoxidil.
According to currently accepted criteria, hypertension in children
is defined as repeated blood pressure measurements at or
above a threshold of which one of the following percentiles for
age, sex, and height?
A.80th
B.85th
C.90th
D.95th
