Q

BMPR2 double hit - what inherited syndrome?

A

familial pulmonary fibrosis

  • First hit - predisposes to excessive endothelial and smooth muscle proliferation

Q

Reliable = ?(aka) = ? definition
v
Accurate = ?definition

Which is the gold standard measurement?

A

Reliable = precise = in same area, not necessarily correct (he doesnt always do a good job, but he is reliable)

Accurate = close to the correct value all the time )gold standard measurement)

Q

Urinary incontinence - etiology of:
stress

urge

overflow

stress- loss of urethral support and intraabdominal pressure exceeds urethral sphincter pressure.

urge - detrusor overactivity/overcontraction

overflow - impaired detrusor contactility (impaired urination), bladder outlet obstruction

filtration fraction =

A

FF = GFR/RPF

RPF = RBF x (1-Hct)
= PAH clearance
= (urine PAH x urine flow rate) / plasma [PAH]

-Manic (1 week of severe symptoms, marked impairment in functioning, psychotic features possible and hospitalization) + or - depressive episode.

  • Hypomanic episode(s) (less than four days, no psychotic features, changes functioning from baseline) + at least one depressive episode
  • at least two years of fluctuating, mild hypomanic and depressive symptoms.
A

Bipolar 1

Bipolar 2

Cyclothymic

29
Q

RBF =

A

= (renal artery pressure - renal vein pressure) / renal vascular resistance
= PAH / (1-Hct)

A

aspergillus

36
Q

Ventricular gallop:

  • Features: turbulent flow through the ventricles due to increased volume or heard during rapid filling of ventricles in diastole.
  • Normal in young adults, pregnancy, children
  • Abnormal in >40, HF, Restrictive cardiomyopathy, high output states
A

S3 gallop (right after S2

37
Q

Atrial gallop:

  • heard immediately after atrial contraction phase as blood is forced through a stiff ventricle
  • Normal in healthy older adults
  • Abnormal in younger adults, children, acute MI, ventricular atrophy
