Q

describe vasculature in the flaccid state and erect state

A

flaccid: arterial vessels constricted and venous vessels are noncompressed
erect: smooth muscle relaxation causes increased blood flow. venous outflow drops as the cavernosal spaces compress the venous plexus and the larger veins

Q

MoA of PDE-5 inhibitors?
which one has the fastest onset?

A

inhibit catabolism of cGMP increasing smooth muscle relaxation. they also enhance insulin signaling, eNOS activity and NO production

Q

To determine testosterone deficiency, the pt should measure their morning fasting total testosterone. if it is low, what are the following steps?
if confirmed low T, pt should measure their LH and FSH, depending on their levels, what is the diagnosis?

A

confirm by repeating morning fasting total T
if still low, diagnosis of hypogonadism is confirmed.
if low LH and FSH, pt has secondary hypogonadism and measure prolactin and iron saturation. if high, pt has primary hypogonadism and should obtain karyotype to diagnose Klinefelter syndrome

Q

Monitoring of TRT:
injectables:
Gels:
Patches:

A

inject: make sure T interval is between 350-600
gel: monitor T concentration 2-8 hours after applying
patch: assess 3-12 hours after applying

19
Q

what is the Prostate/Androgen pathophysiology?

A

hypothalamus release GnRH to pituitary. Pituitary releases LH and FSH to testes and ACTH to adrenal system to produce testosterone and androstenedione respectively. These are converted to dihydrotestosterone (DHT) by 5-a reductase in the prostate which induces growth and development of the prostate gland

20
Q

IPSS Prostate Symptoms Score: what AUA Sx Score classifies the disease severity?

A

7 or less = mild
8-19 = moderate
20 or more = severe

21
Q

when would surgery be required to treat BPH?

A

if pt has:
urinary retention
recurrent UTI
recurrent or persistent hematuria
bladder stones
renal insufficiency

22
Q

what are the pharmacological treatments for BPH?

A

PDE-5i: Tadalafil
a1 blockers: alfuzosin, doxazosin, silodosin, tamsulosin, and terazosin
5-alpha-reducatase inhibitors (ARIs): finasteride and dutasteride
anticholinergics (only if PVR less than 250)

23
Q

which BPH treatments helps relax prostatic smooth muscle and relieves bladder obstruction, but don’t decrease prostate size or disease progression?

A

alpha blockers and PDE-5 inhibitors

24
Q

which BPH treatment does not relax prostatic smooth muscle, but relieves bladder obstruction and decreases prostate size and disease progression?

A

5-a-reductase inhibitors

25
Q

what alternative supplements can treat BPH?

A

none

26
Q

what do we measure to determine prostate cancer?

A

prostate-specific antigen test and digital rectal exam (DRE)

27
Q

The gleason score is used to determine how the cancer looks, and typical scores range from ____, and the higher the score means?

A

6-10. the more likely the cancer will grow and spread quickly

28
Q

what is the 5-year survival rate of prostate cancer based on stage I-IV?

A

stage I: 90-95%
stage II: 60-70%
stage III: 30-40%
stage IV: 20%

29
Q

what is androgen deprivation therapy and when do we use it?

A

a treatment for prostate cancer if cancer has spread too far to be cured by surgery or radiation, or if cancer remains after radiation or surgery

30
Q

what LHRH agonists treat prostate cancer?

A

leuprolide
goserelin
triptorelin
histrelin

31
Q

what LHRH antags treat prostate cancer?
