Q

What are the general features of endometriosis?

A
  • Endometrial tissue that forms TUMOR-LIKE NODULES (foci) outside the uterus.
  • Foci composed of endometrial glands & stroma. (these glands respond to estrogenic stimulation & proliferate with the normal endometrium)

Note:
Ovarian endometriosis may present w/ large cystic lesions. The cysts are filled w/ red-brown fluid derived from decomposed blood = Chocolate Cyst.

Q

What is the most popular theory for the pathogenesis of Endometriosis?

A
  • Endometrial tissue is regurgitated during normal menstruation & instead of entering vagina, it is transferred upstream, it enters abdominal cavity thru fallopian tubes. The glands implant on the serosa of ovary or peritoneum.
  • Forms typical red-brown nodules or plaques. Most foci of endometriosis are located close to orifice of fallopian tubes which support this theory.

Q

What can reduce the risk of endometrial carcinoma, why?

A
  • Multiple pregnancies reduce because progesterone, (dominant pregnancy hormone) gives the endometrium long breaks from proliferation.
  • Estrogens stimulates proliferation of endometrial glands, (hyperplasias) which undergo malignant transformation.

Q

-What is the most common cause of ectopic pregnancy ?

A

***Most common pathologic condition leading to ectopics is chronic salpingitis.

-Other factors: peritubal adhesions as from endometriosis, previous surgeries & leiomyomas.
The intratubal adhesion forms a barrier to normal passage of the zygote, so implants at the site of obstruction.

Q

What are the two MOST common complications of chronic salpingitis from PID ?

A

1) Sterility (infertility): Risk rs increases w/ each Gonococcus infection, & caused by scarring of fallopian tubes, (occludes the lumen and prevents sperm from reaching the ovulated egg.)

2) Ectopic pregnancy: Increase w/ previous salpingitis.
Most common site for Ectopic being the fallopian tubes

  • Abscesses: may develop in the fallopian tubes, ovaries, or peritoneum
  • Peritonitis: bacteria may spread from ovaries & fallopian tubes.

49
Q

What is a Hydatidiform Mole?

A

A placental abnormality marked by trophoblastic proliferation & hydropic degeneration of chorionic villi

50
Q

What is the MOST COMMON form of a hydatidiform mole ?

  • What is androgenesis?
  • What happens without maternal chromosomes?
A

THE COMPLETE MOLE:

  • The fetus cannot be identified in the amniotic sac.
  • Results from abnormal fertilization, where all of the chromosomes are PATERNAL in origin due to loss of maternal chromosomes from zygote at the time of fertilization.

Androgenesis = Paternal 23,X set of chromosomes re-duplicates to create 46 chromosomes.

-Without maternal chromosomes, embryo cannot develop, & placenta undergoes hydropic degeneration.

51
Q

Describe an Incomplete hydatidiform mole

A
  • Evolve from oocytes fertilized with 2 spermatozoa, therefore, cells have 69 chromosomes (1 maternal set, 2 paternal sets).
  • This combination is LETHAL, but embryo DOESN’T die immediately, so parts of embryo are found encased among the hydropically altered placental villi & normal placental tissue.
52
Q

What is the diagnosis of Hydatidiform Moles based on ?

A

-H. moles is RARE

-Based on enlarged uterus for
the corresponding, calculated duration of the pregnancy, without any signs of fetal movement.

  • Ultrasound is the best method for early detection. Look for Snowstorm Pattern with no fetal heartbeat or movement.
  • High serum & urine levels of hCG are typically found. They are aborted spontaneously mid-pregnancy.
  • It is important to remove all parts of abnormal placenta. Any remaining trophoblastic cells could give rise to malignant tumors.
53
Q

What is Wharton’s Jelly?

A
  • Mucous connective tissue in umbilical cord
  • Gelatenous substance of umbilical cord that provides insulation & protection
  • Also the site of umbilical cord stem cells.
54
Q

What is Meconium?

A
  • Fetal feces & first feces of newborns.

- Sticky, tarry, yucky

55
Q

What is Decidua?

A

-As the blastocyst implants, into the endometrium it stimulated the Decidual Reaction.

  • The cells of the endometrial stroma (fleshy endometrial tissue between glands of inner lining endometrium) accumulate lipids & glycogen, become plump, & are transformed into decidual cells.
  • This stroma thickens & becomes highly vascularized, & the endometrium is called DECIDUA & is READY for blastocyst implantation
56
Q

What are Meconium-Stained Placentas?

A
  • Green-colored staining of the fetal membranes that easily rinses off.
  • Found in 18% of placentas & occurs most commonly in placentas from pregnancies that are prolonged beyond 42nd wks of gestation.
  • Related to acute fetal hypoxia & distress, but this recently has been challenged.
  • Major complication of thick meconium is aspiration causing a fetal chemical pneumonitis
  • Histologically, there are meconium-laden macrophages w/in fetal membranes.
57
Q

Know the differences between placenta accreta, increta, and percreta based on the levels into the myometrium and beyond

A
  • Placenta Accreta: the attachment of the villi to the level of the myometrium without further invasion
  • Can result in uterine rupture, hemorrhage (due to fragments)
  • Placenta Increta: villi invade the underlying myometrium
  • Placenta Percreta: villi penetrate the full-thickness of the uterine wall
58
Q

Normal parameters of the placenta

A
  • ~ 22-24 cm in diameter, and 2.5-3.0 cm thick.
  • Weighs approximately 500 gms. (1 lb.)
  • The maternal surface is dark red/ maroon in color & divided into lobules or cotyledons. It is important that this structure be complete with no missing cotyledons.
  • The fetal surface is shiny, gray & translucent enough to see the color of underlying cotyledons. Fetal membranes (amnio-chorion) are gray, shiny, wrinkled & translucent.
59
Q

Normal parameters of the umbilical cord

A
  • At birth is pearly white, 1-2 cm in diameter, & 50-60cm long.
  • It is eccentrically positioned, & contains the right/left umbilical arteries, the left umbilical vein, & mucous connective tissue called Wharton’s Jelly.
  • The right/left umbilical arteries carry DEoxygenated blood from fetus to placenta. The umbilical vein carries oxygenated blood from placenta to fetus.

(Presence of 1 umbilical artery within cord is abnormal = cardiovascular abnormality)

60
Q

____________ carries the HIGHEST amount of oxygenated blood from the placenta to the fetus.

A

The UMBILICAL VEIN

61
Q

Normal parameters of the amniotic fluid ?

A
  • Amniotic fluid volume INCREASES thru the 7th month & DECREASES in the last 2 months.
  • At birth volume of amniotic fluid is around 1 liter. Rate of water exchange w/in the amniotic sac is 400-500 ml/hr.
  • The term fetus swallows 400ml of amniotic fluid & excretes 500ml of urine daily.
62
Q

What does the Amniotic fluid components contain?

A

-Electrolytes, carbohydrates, amino acids, lipids, proteins (hormones, enzymes,& alpha-fetoproteins), urea, creatinine, desquamated fetal cells, fetal urine & feces (meconium) & fetal lung liquids (lecithin & sphingomyelin), useful in fetal lung maturity.

  • Maternally derived water is similar to blood plasma (continually produced & constantly resorbed)
  • *L/S ratio - higher (2:1) correlates with lung maturity
63
Q

What are cotyledons and where would you expect to find them?

A
  • 15 to 30 divisions of placenta
  • found on the maternal side of placenta
  • consists of main stem of chorionic villus
  • cotyledons remaining in mother AFTER birth causes post-partum hemorrhaging
64
Q

Which hormone secreted from the placenta is known as the growth hormone for the fetus?

A

-Human Placental Lactogen (hPL):

protein hormone that induces lipolysis thus elevating free fatty acid content in mom

65
Q

What is the differenece between succenturiate placenta vs circumvallate placenta?

A

(Accessory) Succenturiate = EXTRA lobes

  • linked by thin chorionic tissue
  • No clinical importance, unless a portion of lobe is retained after birth - post-partum bleeding

Circumvallate = rolled & raised ring of fetal membrane
over fetal surface instead of edge of placenta (chorionic plate < basal plate).
-The blood vessels at chorionic plate stop at raised membranes & run deeper under membranes.
-Associated w/ Prematurity
Prenatal bleeding, Placental abruption or Multiplarity (more than on fetus)

66
Q

What is the Normal distribution of umbilical cord, how many arteries and veins?

A

  • Genital Mycoplasma species (M. hominis and U. urealyticum)
  • anaerobic Bacteroides group
  • Aerobe Group B Streptococcus, E. coli & Gardnerella vaginalis

Q

What is funisitis?

A

Inflammation of umbilical cord caused by intrauterine infection; acute fetal inflammatory response

  • Signs/symptoms: Vasculitis of umbilical vessels, PMN infiltration after extension of Wharton’s jelly
  • Causes: meconium exposure, spread of chorioamnionitis, Candida, Actinomyces, HSV, Syphilis
  • Can be necrotizing (infiltration through vessel into Wharton’s Jelly), or peripheral (microabscesses on surface)

Q

–Where are all the locations that can harbor choriocarcinoma

A

Placenta primarily. Also in endometria (ovaries) and testicles. It can metastasize to bone, liver and lungs.

74
Q

Which organ has estrogen receptors

A
  • Ovaries, breasts, and endometrium, 1-2% risk of cancer in those areas
  • Breast and Uterus are the main ones. The Brain, Bone, liver and heart also have estrogen receptors.
