Q

Endometrium in phases of menstrual cycle

A

Proliferative phase

  • estrogen driven

Q

Porstatic plexus

A

Lies within the fascia surrounding the prostate. Originates from the inferior hypogastric plexus. Includes cavernous nerves which innervate the corpora cavernosa of the penis and urethra and parasympathetics resonsible for erection. Damage during prostatectomy can cause erectile dysfunction.

Q

Uretrhal injury due to trauma: presentation, and most common location

A

Inability to void, blood at urethral meatus, high riding boggy prostate due to hematoma formation behind th gland. Pelvic trauma most commonly causes damage to the bulbomembranous junction of the urethra where it curves.

A

Collection of peritoneal fluid in the tunica vaginalis. Due to failure of the connection between tunica vaginalis and peritoneum to obliterate. Common in newborns. Presents as painless scrotal swelling that transilluminates

Q

Male urethra portions

A
  1. Prostatic urethra: widest portion, where other ducts dump in
  2. Membranous urethra: passes through perineal membrane and surrounded by perineal muscles. Narrowest part
  3. Penile urethra: longest part

Q

Urethral rupture above vs below urogenital diaphragm

A

Urogenital diaphragm is the junction between the membranous and penile urethra.

Rupture below: urine goes to scrotum and perineum
Rupture above: urine goes to retropubic spaces

19
Q

Bicornuate uterus

A

Failed fusion at the top of the uterus; single cervix. Most common uterine anomaly

20
Q

Septate uterus

A

Normal external shape (doesn’t have two horns) but have two separate cavities inside

21
Q

Arcuate uterus

A

Small midline indentiation; failure of septum to completely dissolve

22
Q

DES uterus

A

Due to exposure to DES in utero. T shaped uterine cavity

23
Q

Ligaments of ovary: suspensory, cardinal/transferse cervical, round

A

Suspensory: house ovarian artery and vein
Cardinal/transferse cervical: house uterine arteries. Form base of broad ligament
Round ligament: no structures

24
Q

Embryologic structures that give rise to external genitalia

A

Genital tubercle: glans penis/clitoris
Urogenital folds: ventral shaft of penis/labia minora
Labioscrotal folds: scrotum/labia majora

25
beta-hCG structure
shared subunit with TSH, LH, and FSH
26
Organogenesis
Occurs during weeks 3-8. When exposure to teratogens is the most concerning
27
Testicular seminoma
Large cells with clear cytplasm and central nuclei. Homogenous mass without hemorrhage or necrosis. Good prognosis
28
Embryonal germ cell testicular tumor
Hemorrhagic and necrotic. Can form glands. Aggressive. May differentiate when give chemo
29
Yolk sac testicular tumor
Seen in young kids. Schiller Duval bodies (glomeruloid like structure). Elevated AFP.
30
Choriocarcinoma testicular tumor
Makes beta hCG. Synctiotrophoblasts and cytotrophoblasts but no villi. Spreads early via blood.
31
Twinning - timing
Day 3 or earlier: di/di Day 4-8: mono/di Day 8+: mono/mono
32
Epispadius vs hypospadius
Epispadius: urethral opening on dorsal penis. Caused by abnormal development of genital tubercle Hypospadius: urethral opening on ventral penis. Caused by abnormal development of urogenital folds
33
Development of prostate
Exception in that it doesn't develop from Wolffian duct, develops from urogenital sinus along with prostatic urethra in response to testosterone
34
Complete vs partial mole: uterine size, beta hCG, and immunohistochemistry
Complete: enlarged uterus inconsistent with dating, extremely high beta hCG, p57 negative Partial mole: normal uterus, normal to high beta hCG, p57 positivw
35
Cell cell connections during labor
Just prior to labor, estrogen stimluates upregulaton of gap unctions while increases myometrial excitability
36
Krukenberg tumor
Primary gastric cancer metastasized to ovary. Pathology is signet ring cells producing mucin
37
Uterine fibroids: pathology, locations, presentation
Pathology: Benign, monocloncal tumors of uterine smooth muscle. Express estrogen receptors and are estrogen responsive (can enlarge with increased estrogen and cna regress with menopause or leuprolide) Locations: Subserosal most common, intramural (in uterine wall), or submucosal (below endometrium) Presentation: pelvic pressure, menorrhagia, metrorrhagia, constipation if in the posterior uterus, obstructive urinary symptoms if displaces uterius upward
38
High vs low grade CIN
HIgh grade: invades beyond lower 1/3 of cervical epithelium (to epithelial surface); associated with HPV 16 or 18 and often progress to cancer Low grade: cells not invaded past lower 1/3, associated with HPV 6 and 11; usually regress
39
Ureter injury during hysterectomy
Very common due to close proximity of ureter and uterine artery. Injury with suture causes flank pain due to urine obstruction. Transection causes urine leak and flank pain. Voiding can be normal as injur y is unilateral
40
Congenital torticollis
Presents at 2-4 weeks. Caused by birth trauma or malposition of the head in utero. Damage to SCM muscel results in fibrosis and contraction. HEad is tilted toward affected side
41
Infundibulopelvic ligament
Another name for suspensory ligament of the ovary. Houses ovarian vessels and ovarian nerve plexus
42
Distinguishing causes of vaginal bleeding during pregnancy
Abruptio placentae: painful vaginal bleeding in 3rd trimester, prior to labor. May see initiation of contraction. Risk factors include HTN, smoking, cocaine Uterine rupture: painful vaginal bleeding during labor, seen during vaginal delivery in women wtih prior C section Placenta previa: placentation that covers cervical os; painless bright red vaginal bleeding
43
PCOS diagnosis
Based on - clinical symptoms: hirsutism, insulin resistance, infertility, anovulatory bleeding, enlarged cystic ovaries - LH/FSH 3:1 (normal is 1.5:1)
44
Paget disease of nipple: histology
large cells with clear halos
45
Phenytoin side effect
horizontal nystagmus on vertical gaze
