(139 cards)
1
Q
Layers of penis:
A
Outer dermis Dartos fascia Deep Buck's Fascia Tunica albuginea then CORPUS CAVERNOSA or OR SPONGIOSA (latter is around urethra)
2
Q
Nerve for boner?
A
Pelvic Nerve (parasympthatic)
NO makes more cGMP and sildenafil prevents breakdown
NE causes more Ca++ in the muscle and smooth muscle contraction and vasoconstriction and fight or flight so you don’t want blood to penis then)
3
Q
Nerve for emission?
A
Hypogastric nerve
4
Q
Nerve for ejaculation?
A
Pudendal nerve (visceral and somatic nerve)
5
Q

Uterine vessels?
A
Suspensory ligaemnt
Cardinal ligament
7
Q
Venous drainage of Left vs right gonadal veins? clinical significance?
A
Left is to Renal vein to IVC (takes a right angle, so vericocele more common in left b/c 90 degree angle and blood leaves slower)
Right is to IVC directly
Adrenals do the same thing! Q bank damn!
8

look like woman, but inside is male. Genetics is male. Testes often in labia majora (lumps there are often there in test)
High estrogen and LH b/c body not getting feedback
24
Q
5 alpha reductase insufficiency?

How long does ti take BhCG to be detected?
2 weeks after conception (smart, that is when period would start anyway)
Serum is a week after conception (implantation time)
57
Why do OCPs help with acne?
estrogen causes liver to make more steroid binding hormone, so less free and active testosterone

Dangers of OCP
Smokers over 35. Patients with aura and migraine! (risk of stroke b/c vasospasm!)
HTN, triglycerides, GI and weight gain.

Might have affect lasting a year (want it to last 3 months) Not good if you want to be pregnant in 6 months.
May cause bone mineral density lost if long term, so use less than 2 years
Irregular bleeding and stuff
60
Who is IUD contraindicated for?
STD high risk (when you place it, you can push chlamydia or gonnohrea up higher, thats shitty b/c ascending infection and PID risk)
61
Why hirsuitism in menopause?
change in balance of estrogen/androgen
62
Allodynia vs hyperalgesia?
allodynia is stimulus that shouldn't cause pain causes pain
hyperalgesia is over sensitized to pain

```
73
What is leiomyoma (fibroid)? histo? Symptoms?
Benign smooth muscle tumor common in women. COMMON
NO RISK OF CANCER even though they come from single cell
Decreases with menopause b/c estrogen sensitive. So OCP is tx (b/c controlled estrogen), Leuprolide, ablate, myomectomy, Hysterectomy
histo is whorled pattern
ASYMPTOMATIC, OR vaginal bleeding, bulk systems, miscarriage if poor blood supply, can cause PAIN if necrosis (but rare outside of pregnancy)
74

2 of the 3
Oligo- or anovulation
Hyperandrogenism
Polycistic ovaries on US
81
PCOS is a 4 star topic. so list the three ways it can develop?
High LH:FSH from pituitary/hypothal issue causes theca cell to make a ton of androgen (hirsuitism) which is made to estrogen by granulosa which feedback inhibition stops FSH from being released (and follicles don't develop) and you get an ovulation.
Or you could: peripheral adipose makes more estrogen
Or you could have insulin resistance causing more insulin to be released which stimulated theca cells and decreases liver synthesis of androgen hormone binding globulin (hirsuitism)
82
What are the treatments for polycystic ovarian syndrome?
Weight loss
Metformin
PROGESTERONE (to protect endometrium from unopposed estrogen)
Clomiphene (blocks the estrogen negative feedback)
Leuprolide pulses to get back ovulation
Spironolactone (antiandrogen)
Ovarian drilling (a weird thing done surgically and people aren't sure why it works)
83
What is clomiphene?
Partial agonist at estrogen receptor in hypothalamus (makes a competitive inhibitor to decrease negative feedback AT HYPOTHALAMUS) so you can increase FSH!
84
What is CA 125?
A way to monitor progression of ovarian tumors (but terrible for screening b/c non-specific)
85
20% bilateral, unilocular cyst lined by fallopian tube epithelium (ciliated) is what kind of ovarian tumor?
Serous cystadenoma
86
What type ovarian tumor is often bilateral with fallopian tube epithelium or potentially anapestic? It can have psammoma bodies.
Mucinous cystadenoma (50% of ovarian tumors)
Psammoma bodies are concentric rings of calcifications
87
What type of ovarian tumor is unilateral, potentially being multilocular and large and lined by columnar cells that look similar to intestine on pathology?
Mucinous cystadenoma (there is a pic on 582 of first aid, check it out on the PDF)
88
What ovarian tumor can cause pseudomyxoma peritonea? What else can cause this?
Mucinous cystadenocarcionma. Looks like adenocarcionma of the intestine.
Pseudomyxoma peritonei is intraperitoneal mucinous material (i think joe saw a guy with this in clinic) which can happen with appendices cancers as well)
89
What tumor looks like transitional cell of the bladder? It has COFFEE BEAN nuclei (first aid mentions this as does DIT)
Brenner tumor (it is encapsulated so it is benign)
The nuclei look like little blue/purple coffee beans)
BrennER is BladdER
90
What is difference between mature and immature teratomas? One of them can they secrete causing strum ovarii?
95% are mature and benign "Dermoid cysts"
5% are immature with neural elements and in the 1st or 2nd decade of life.
they can have functionally thyroid tissue making a person hyperthyroid and if so, it is more likely to be a mature (benign) teratoma
91
What type of ovarian tumor has sheets of uniform cells?
dysgeminoma: hCG and LDH are tumor markers
92
What is dysgerminoma associated with? What are the markers?
Turner syndrome. LDH and hCG
93
What are sheller duval bodies? if you see it, what is a tumor marker for it?
Endodermal sinus (Yolk sac tumors) have them, they are resembling glomeruli
AFP is the marker
94
What ovarian tumor differentiates towards trophoblastic structures with only maternal DNA? Is it dangerous?
Ovarian choriocarcionma develops syncytiotrophoblasts and cytotrophoblasts so makes hCG!
Yes metastasize, b/c trophoblastic tissue is designed to be invasive (to be able to do blood exchange in placenta, so they can invade tissues)
95
What is Meigs syndrome?
Ovarian Fibroma, ascites, pleural effusion (hydrothorax)
pulling sensation in the groin
96
What are Call-Exner bodies found in? What do they look like? And what findings do you have in serum tests?
Malignant Granulosa cell tumor and they make estrogen/progesterone which makes sense.
Call exner bodies resemble primordial follicles (disarrayed granulosa cells in eosinophilic fluid)
can cause endometrial hyperplasia and breast tenderness
If in kids, can cause precocious puberty,
97
What is a mucin-secreting signet cell adenocarcionma?
Kruckenberg tumor (nucleus is pushed to one side b/c all the mucoin in the cell)
They are from GI (which makes sense b/c GI makes a lot of mucin)
98
What is the fetal component of the placenta? What does what?
Cytotrophoblast make Cells and is inner layer of chorionic villi
Syncytiotrophoblast is outer layer and Secretes hCG (stimulates corpus luteum as it is similar to to LH.)
Syncytiotrophoblast Syncs with mother
99
What is the maternal component of placenta?
Decidua basalis (from endometrium)
Maternal blood is in the lacunae and is around syncytiotrophoblast
100
G#P#A#?
Gravidity is number preggers
P is number delivery
A is huber of abortions/miscarriage
101
Why is glucose high in pregnancy?
human placental lactogen is released which is important to allow more nutrients to baby
102
Quad screen for DownSyndrome?
low AFP high betaHCG low estriol
Easy to remember b/c it is every other if you do it alphabetically and you start down b/c down syndrome
103
What are the markers for trisomy 18?
low everything, AFP bhCG and estriol (think of it as more severe, so everything is low)
104
What cause increase in AFP during preggers?
NEURAL TUBE DEFECTS (biggie)
Abdominal wall defects
multiple gestation
105
What is risk of of amniocentesis?
0.5% risk of fetal loss and risk of of 1-2% of fetal/maternal hemorrhage
106
What do you see if monozygotic twins split before 4 days?
4-8 days?
8-12 days?
13+ days
0-4 before chorion is made, so dichorionic and diamniotic
4 days is chorion formed, so 4-8 days is monochorionic and diamniotic (shared placenta)
8 days the amnion is formed so they are monochorionic and mono amniotic (floating with nothing separating the two
13 days is when embryonic disc is formed so the twins are conjoined if splitting happens here
107
What happens with twin-twin transfusion syndrome?
Anastomis in chorion causes shunting of blood.
Donor is growth restricted and anemic
Recipient is polycythemic, overloaded and has heart failure and comes out worse than donor
108
What do you suspect if uterine rupture in pregnancy?
Complete mole. (complete moles are completely worse)
109
What is it called when placenta attaches over cervical os? How does it present?
Placenta previa. Partially covers or completely covers it.
PRESENSTS as painless vaginal bleeding
Dx is ultrasound. DO NOT put your finger in and rupture anything
Risk factor: multiparty, makes sense, prior C section b/c scarring
110
What is vasa previa?
Fetal blood vessels over cervix
111
3 types of placental invasion into uterus. What are they? How do you tx? How are they caused?
Placenta Accreta ATTACHES to myometrium without penetrating it
Placenta INcreta goes INTO myometrium
Placenta PERCRETA PERForates through myometerium
Life threatening b/c exposed vessels will bleed, need to do hysterectomy.
The mother made a defective dicidual layer so the placenta infiltrates
Prior c section is a risk b/c scar makes for poor basalis
112
Third trimester has painful vaginal bleeding. What is it?
Placental abruption. Can lead to DIC
Predisposed with trauma (makes sense)
Cocaine
Vasoconstriction can cause it: preeclempsia, cocaine use
Dx: Kleihauer-Betke checks for fetal blood in mom
113
What can cause oligohydramnios?
Placental insufficiency
Bilateral renal agenesis
Posterior urethral valves
114

Tx for eclempsia seizure?
Delivery!
IV magnesium and its side effects are:
low reflex, pulmonary edema, altered mental status, cardiac conduction defects
117
Similarities and differences between gestational diabetes and Type 1/II diabetes in pregnancy?
Similar: Macrosomia and stillbirth (later high sugars, after human placental lactogen kicked in)
Different: Type I/II cause miscarriage or abnormalities (b/c differences diabetes is bad for vessels and high blood sugar doesn't come up until later in pregnancy normally, but if high in first 20 weeks, it is bad)
Congenital heart defects
Caudal regression syndrome
Nueral tube defects
That doesn't happen with gestational diabetes b/c that doesn't happen until after vessel development of baby
118
Majority of miscarriage is what?
Trisomy 16
119
PCOS can cause infertility. How do you fix that?
Clomiphene or metformin
120
What are the different drug categories for pregnancy (if you want an exhaustive list of where drugs fall, page 237 can help you out)
Category A (safety established in human studies)

C no studies have shown things, uncertain safety
D human risk, but benefit may ouweight risk
X: NEVER OK TO USE
121

Methyldopa
Labetalol
122
Diabetes tx in preggers?
Insulin (important to make sure to take care of it pregestationally)
123
Tx for epilepsy in preggers?
Anything that helps control seizures b/c seizures are bigger risk EXCEPT avoid valproic acid
Supplement with folic acid b/c NTD risk
124
Tx for hyperthyroid in preggers?

125
Anticoag tx during preggers?
Heparin or enoxaparin
NEVER WARFARIN
126
What are tocolytics? 4 of them

Nifedipine: calcium cahnnel blocker causes myometrial relaxation
Terbutaline: beta2 agonist to relax myometrium
Magnesium sulfate seizure prophylaxis also
127
Drugs for promoting labor?
Prostaglandins. DinoPROSTone is PGE2 and misoPROSTol is PGE1 (cervical relaxation and uterine contractions). Risk of tachysystole that can cut off blood flow or uterine rupture if scarred uterus
Oxytocin
Both can be used to fix atony to stop bleeding after delivery
128
Chemical abortificants that are approved? Which is specific for ectopic?
Mifepristone: progesterone antagonist
Misoprostol: PGE1 analog to cause uterine contraction to kick out the pregnancy (expulsion)
Methotrexate for ectopics. Folic acid antagonists so cells don't grow
129

```
Duodenal atresia
Endocoardial cushion
Risk of ALL/AML (ALL)
ALLzheimer disease
Polycythemia (65% newborns with down's have it)
```
ALL fall DOWN (down's syndrome from that ring around the rosie song)
Down alpha fetoprotein
UP betaHCG
down estriol
Up inhibit A
Ultrasound is more nuchal translucency (also turner syndrome)
131
What does Edwards syndrome look like?
Trisomy 18. Rocker bottom feet, micrognathia (small jaw), low set Ears (Edwards), clenched han and congenital heart disease. Death within a year. (so it is bad, so in had screen EVERYTHING is low)
Normal inhibin A
132
What do you see with Patau?
Patua is trisomy 13. P disease
Clef liP/Palate, holoProsencephaly, Polydactyly, microcephaly, mircroPhthalmia
Screening: everything is low but INCREASED nuchal translucency (like down)
No quad screen, but you do see decreased betahCG in first trimester. PAPP-A is decreased
133
Klinefelter presentation?
Tall, less testosterone (so hips are big and female hair distribution). Infertal, dysgenisis of seminiferous tubules, so less inhibit so more FSH
Inactive X is BARR Body and present
134
Turner syndrome presentation?? What heart conditions do you have?
```
Short
shield chest
webbing of neck
gonadal dysfunction (streak ovaries)
most common cause of primary amenorrhea
