SAS/Review Flashcards
Which antibiotic is associated with pumonary fibrosis?
Nitrofurantoin
What is the treatment for endometrial hyperplasia?
Progesterone therapy or hysterectomy
(Sometimes do progesterone now, plan hysterectomy for later if pt wants to have more children)
B - rule out other sources of hyperandrogenism
Most likely PCOS, but cannot say definitively until other causes (tumor, CAH, Cushing) are ruled out
List the estrogenic (4) and anti-estrogenic (2) effects of tamoxifen
-
Estrogenic
- Venous thrombosis :(
- Endometrium: polyps, hyperplasia, risk of cancer :(
- Maintains bone density :)
- Maintains vaginal mucosa :)
-
Anti-estrogenic
- Breast :) - fights cancer!
- Hot flashes :(
List 2 nerves that innervate levator ani
Pudendal nerve (inferior rectal branch)
Nerve to the levator ani
Nerve to the levator ani is also from the anterior branches of S2, S3, S4, but not the same as the pudendal
Which kidney stones are diamond-shaped?
Calcium oxalate
What is the most malignant tumor involving the spermatic cord?
Liposarcoma
Describe the management of placenta previa
- Pelvic rest
- Expectant management
- Give antenatal steroids if <34 weeks
- Planned C-section at 37 weeks
What is the function of prostate-specific antigen?
Liquifies semen
(And also used as a marker for prostate cancer)
In a patient with functional hypothalamic amenorrhea, what would you expect the results to be from:
- Prostestin challenge:
- Estrogen + progestin challenge:
- Prostestin challenge: No bleeding (negative)
- Implies either outflow obstruction OR low estrogen
- Estrogen + progestin challenge: Bleeding (positive)
- Implies low estrogen; cause of amenorrhea is central
- Functional hypothalamic amenorreha = suppresed GnRH -> no LH/FSH -> no estrogen or progesterone*
- NOTE: GnRH levels cannot be measured in the blood*
Which nerve is responsible for emission?
Which one is responsible for ejaculation (aka expulsion)?
(How are these two entities different?
Emission: Lumbar sympathetic nerves
Ejaculation (expulsion): Pudendal nerve (somatic)
- Emission gets semen to the posterior urethra*
- Ejaculation gets it out into the world*

Which imaging study is most useful for diagnosing hydronephrosis?
Ultrasound
CT is pretty good, but, not the best for imaging things with a large cavity in the middle
A patient on a combined OCP is experiencing nausea and breast tenderness.
Which hormone is most likely responsible for these effects?
How would you modify her OCP to mitigate these effects?
Estrogen
Switch to a combined OCP with a lower dose of estrogen
What is the usual natural history of mild cervical dysplasia due to HPV infection?
Usually, the dysplasia will regress and resolve
- Can progress - slow growing
- More likely to progress in immunocompromised individuals
Which hormone can be measured (and when) to predict ovulatioN?
Serum progesterone on day 21 and 27
More reliable than temperature charting
MOA: Finasteride
5-alpha-reductase inhibitor
Acts as an anti-androgen by preventing the conversion of testosterone to the more potent DHT
Anti-androgen therapy helpful in the treatment of BPH
6 weeks after surgical removal of a cancerous prostate lesion, a patient’s PSA is elevated (>0.1 ng/mL)
What is the best adjuvant approach?
Combined androgen ablation + radiation
What is the female homolog of the male prostate?
Where is it located?
Skene gland
Around the opening of the urethra
(In the vestibule, anterior to the opening of the vagina)
Where would a Gartner’s duct cyst be located?
What cause this cyst?
Anterolateral aspect of the proxmal vagina
Wolffian duct remnant
Which GI complaint is most common in the first trimester of pregnancy?
Why?
Nausea + vomiting
Caused by high hCG
What are the histologic features of a mixed germ cell tumor (embryonal carcinoma) of the testes?
Solid, glandular, and papillary patterns
What is the primary arterial blood supply to the prostate?
Inferior vesical artery
What is the half life of PSA?
2-3 days
What is the differece between mild, moderate, and severe cervical dysplasia?
- Mild = lower 1/3 of epithelum only
- Moderate = Involves middle 1/3 and lower 1/3 of the epithelium
- Severe = Involves the hwol epithelium
What is the most serious and likely side effect estrogen-only hormone replacement therapy?
Endometrial cancer
DVT also possible, but less common?
What is the histologic hallmark of a yok sac tumor?
Schiller-duvall body
If a patient’s testicular tumor markers do not normalize after orchiectomy, what is the next step in their managment?
Start chemotherapy
- If tumor markers don’t normalize, implies metastatic disease*
- Do chemotherapy; if tumor markers normalize, can do post-chemotherapy surgical resection (PC-RPLND)*
What is the most common position of the uterus on bimanual exam?
Anteverted
(Why we can feel the uterus on bimanual exam)
Which of the following is NOT a contraindication to hormone replacement therapy?
- Active breast cancer
- Unexplained vaginal bleeding
- History of endometrial cancer
- Liver disease
- Previous VTE
c. History of endometrial cancer
* Active endometrial cancer would be a contraindication, but if it’s gone then go for it*
Which laboratory test is most valueable in monitoring a patient’s response to syphilis treatment?
Rapid plasma reagent
FTA and NAAT are used for diagnosis
Which kidney stones are “coffin shaped”?
Struvite
Associated with urease-producing bacteria
D: Platinum-based chemotherapy
Chemotherapy is not effective on metastatic RCC!
Abnromalities in what non-repro organ system are commonly associated with Mullerian duct anomalies?
Renal

Right testis?
Left -> Paraaortic nodes
Rigth -> Interaortocaval nodes
Which muscles make up the levator ani? (3)
- Puborectalis
- Pubococcygeus
- Iliococcygeus
**Ischiococcygeus (aka coccygeus) is NOT part of levator ani
Note: Cochard kind of groups the puborectalis as part of the puboccygeus
What is the serum half life of AFP?
5-7 days
Relevant b/c need to measure AFP to make sure there are no metastases after removing testicular tumor, but need to wait long enough for previous levels to go down
What feature of a patient’s history would make anovulation VERY unlikely?
Regular periods (in a patient not taking any contraceptives)
What percentage of prostate cancers are hereditary?
15%
Which nerve is labeled by #3?
Dorsal nerve of the penis or clitoris
What is the first imaging method used to evaluate a suspected ectopic pregnancy?
Ultrasound
What is the most appropriate next step in management of a patient who has blood at the urethral meatus following blunt trauma to the pelvis and perineum?
Retrograde urethrogram (RUG)
Do not attemt to fully insert catheter if there is any blood (need to rule out urethral injury first)
If there is blood, do a RUG!
What is the primary venous drainage from the prostate?
Dorsal vein of the penis
Internal iliac veins
Venous plexus in the prostate drains there, but presence of plexus = large potential for bleeding
What are the borders of the femoral triangle?
- Inguinal ligament (superior)
- Adductor longus (medial)
- Sartorius (lateral)
Fascia lata separates superficial and deep compartments

Peri-aortic and para-aortic nodes
Obturator nerve
Which 3 nerves innervate the scrotum?
Genitofemoral = lateral and anterior
Ilioinguinal = anterior
Pudendal = posterior
Genitofemoral is also motor to cremaaster muscle
D - poor response to appropriate abx after 3 days
Imaging indicated after 5-6 days without improvement for pyelonephritis
I think the key is that A, B, and C might constitute a “complicated” pyelonephritis and should be imaged?
Note: wait 5-6 days in tx of pyelonephritis, but 3 days in tx of UTI
Which nerve is labeled by #2?
Perineal nerve
Which gonadotropin promotes glomerulosa cell proliferation?
As a result, levels of which hormone will increase?
FSH
- > Incresed estrogen
- Granulosa cells have aromatase that converts androgens from theca cells to estrogen -> proliferation of endometrial lining*
Which gonadotropin is most important for stimulating ovulation?
LH spike
Stimulated by faster GnRH pulses
How can you differentiate between an intraperitoneal and an extraperitoneal bladder rupture?
(Diagnostic test and findings)
How does the management differ?
Cystoscopy
- Intraperitoneal
- Contrast goes up
- Need to do surgery
- Exraperitoneal
- Contrast stays below bladder or goes sideways
- Can cath and observe
- Unless bladder neck, vaginal, rectal, large injury or bone fragments - then do surgery
Which cells create the blood-testis barrier?
Sertoli cells
