Placenta Previa
**Attachment of the placenta to the lower uterine segment--often over the cervical os

**PAINLESS vaginal bleeding
Placenta Accreta
**Defective decidual layer allows the placenta to attach directly to the MYOMETRIUM

**May have MASSIVE hemorrhage after delivery
Predisposing Factors to Placenta Accreta?
=Prior C-section
Abruptio Placentae
**Premature detachment of the placenta from the implantation site due to the formation of a RETROPLACENTAL CLOT

=causes PAINFUL uterine bleeding --> usually in the 3rd trimester

**Can cause FETAL DEATH and DIC

Risk Factors?
=Smoking cigarettes
=Cocaine addiction
=Advanced maternal age
Ectopic Pregnancy
**Most often in the fallopian tubes

SUSPECT w/ an increased B-hCG and SUDDEN lower abdominal pain.
=confirm w/ ultrasound

**Often mistaken clinically for appendicitis.
=i.e. always do a B-hCG pregnancy test to rule out ectopic pregnancy!
**Predisposed by SALPINGITIS (PID)
**TRIAD of:

**Eclampsia = addition of SEIZURES to the triad

**Affects 7% of pregnancy women from 20 weeks - 6 weeks postpartum
=i.e. usually occurs in the 3rd trimester
Who has an increased risk of eclampsia?
**women > 35 y.o.
=patients w/ preexisting HTN
=chronic renal disease

What syndrome can preeclampsia/eclampsia be associated with?
HELLP Syndrome

=Elevated LFTs
=Low Platelets

**i.e. hemolytic anemia + DIC
Gestational Trophoblastic Neoplasms
1) Hydatidiform Moles

2) Choriocarcinoma
Hydatidiform Moles
**Benign tumors of the chorionic villus

**Can be:
1) Complete
2) Partial
Complete Mole
**Most common type

=the ENTIRE placenta is neoplastic
=you see dilated, swollen villi

=46XX --> BOTH chromosomes are of MALE origin
=i.e. the egg is fertilized by 2 haploid spermatozoa w/ X chromosomes

So what would be the clinical findings in a complete mole?
**Enlarged uterus
="honey-combed" or "cluster of grapes" appearance


**Preeclampsia in the FIRST trimester
Partial Mole
**NOT all villi are neoplastic or dilated

**Embryo IS present --> TRIPLOID 69XXY
=i.e. egg w/ 23X is fertilized by a 23X and 23Y sperm

NO INCREASED RISK of developing choriocarcinoma!
**Malignant tumor composed of syncytiotrophoblast + cytotrophoblast

=Bilateral renal agenesis
=Posterior urethral valves (in males) --> and thus an inability to excrete urine
Dysplasia and Carcinoma in Situ (CIN)
**Disordered epithelial growth
=begins at the BASAL layer and exends outward

**Classified as CIN1, CIN2, CIN3 depending on the extent of dysplasia

=associated w/ HPV 16, 18 --> may progress slowly to invasive carcinoma
Invasive Cervical Carcinoma
**Now the LEAST COMMON gynecologic malignancy --> due to early detection of CIN w/ Pap Smears
=i.e. Pap Smear can catch cervical dysplasia (KOILOCYTES) BEFORE it progresses

**Majority are Squamous Cell Carcinoma
Risk Factors
**Same as for CIN

=early age of onset of sex
=multiple, high risk partners
=high-risk types of HPV in the biopsy
=oral contraceptive pills
**Can extend down into the vagina

**Can extend laterally to block the ureters
=i.e. postrenal azotemia leading to RENAL FAILURE is the #1 cause of death!
Uterine Disorders


=Endometrial hyperplasia

=Endometrial Carcinoma


=i.e. glands and stroma THICKEN myometrial tissue --> produces uterine enlargement

**does NOT predispose to cancer!
**Functioning glands and stroma OUTSIDE the confines of the uterus
#1 --> REVERSE menses through the fallopian tubes

=coelomic metaplasia
=vascular or lymphatic spread
Common Sites?
#1 --> OVARIES

=Rectal pouch of Douglas
=Fallopian tubes
Recall: What is the Rectal Pouch of Douglas?
**the MOST DEPENDENT part of the female pelvis
=anterior to the rectum and posterior to the uterus
=can be palpated by DRE

**It is a common site to COLLECT things:
=blood --> ruptured ectopic pregnancy
=malignant cells --> seeding by ovarian cancer
=endometrial implants
=pus --> PID

=Woman comes in and complains that when she is on her period and she is going to the bathroom it really hurts when she defecates. DX?
**endometriosis in the pouch of douglas!
Clinical Findings:
**Women still have cyclic bleeding (=menstrual type) and so have these blood-filled "chocolate cysts"

=Painful stools during menses (rectal pouch)
=enlargement of the ovaries

**Increased risk of ectopic pregnancy
Endometrial Hyperplasia
**ABNORMAL endometrial gland proliferation --> Due to prolonged, UNOPPOSED estrogen stimulation
=NO progesterone effects!

**Usually manifests as VAGINAL BLEEDING

**Will INCREASED risk for endometrial carcinoma
Risk Factors:
=Early menarche or late menopause


=Obesity (i.e. increased aromatization of androgens --> estrogens)

Woman who has been postmenopausal for >1 year and then has breakthrough bleeding.
**Endometrial cancer until proven otherwise

#1 step --> endometrial biopsy

#2 --> ovarian

#3 --> cervical
Most common GYN cancers by AGE BRACKET?

**note: leiomyomas are sometimes referred to as "fibroids"
**Bulky, irregular tumor w/ areas of necrosis + hemorrhage
=HIGHLY aggressive tumor w/ tendency to recur --> may protrude from the cervix and bleed!

**Usually arise de novo--NOT from leiomyomas

**Increased incidence in blacks
Hirsutism vs. Virilization
=excess hair in normal hair-bearing areas

=hirsutism + male secondary sex characteristics (=increased muscle mass, acne, CLITOROMEGALY)
What is the cause of hirsutism and virilization?
**BOTH conditions are due to INCREASED ANDROGENS of either ovarian OR adrenal origin

1) Ovarian origin (=most common)
=TESTOSTERONE is primarily increased

2) Adrenal origin
=DHEA-sulfate is primarily increased

**SO, if someone has hirsutism, get a testosterone level and a DHEA level = tells you where the probelm is!
Polycystic Ovarian Syndrome
**Increased pituitary synthesis of LH and decreased synthesis of FSH
NOW, recall what happens during the proliferative phase:
=LH is responsible for stimulating the THECA INTERNA to synthesize DHEA + androstendione --> converted via oxidoreductase --> TESTOSTERONE

THUS, INCREASED LH leads to an INCREASE in androgen synthesis = HIRSUTISM!

BUT...testosterone will enter GRANULOSA cells of the follicle where there is AROMATASE and be converted into ESTROGENS
What will this increase in estrogens do?
**Increased estrogen has a POSITIVE feedback on LH and a NEGATIVE feedback on FSH
=NOW, suppression of FSH causes follicle degeneration --> FLUID ACCUMULATION produces abnormal cysts that ENLARGE the ovaries

AND THUS our findings in PCOS:
1) increased LH
2) decreased FSH

**Usually have an LH:FSH of >2!
Summary of Clinical Findings in PCOS:
#1 complaint = oligomenorrhea

=hirsutism, infertility, obesity
=polycystic ovaries

1) Increased LH, Decreased FSH
2) Increased testosterone and androstenedione
3) Increased estrogen
=increases your risk of developing endometrial hyperplasia/cancer
How could you break the cycle in PCOS?
**give a BC pill --> progestins in it will BLOCK LH

Also could treat with:
=weight loss
=gonadotropin analogs
**Painful menses

**Can be primary or secondary:

1) Primary
=usually due to INCREASED PGF --> increases uterine contractions

2) Secondary Type
=usually due to endometriosis
Dysfunctional Uterine Bleeding (DUB)
**Bleeding that is UNRELATED to an anatomic cause
=i.e. NOT from endometrial polyp or cancer


**Most common type of DUB = Anovulatory DUB
Anovulatory DUB
**Occurs at the extremes of reproductive life

**What happens is that you have EXCESSIVE estrogen stimulation of your mucosa and not enough progesterone stimulation --> results in:

=hyperplasia of the endometrium --> when it outgrows its space, it will SLOUGH --> can often have SIGNIFICANT BLEEDING
Primary Amenorrhea
**Absence of menses by 16 y.o.

=i.e. FH of delayed menses
Secondary Amenorrhea
**Absence of menses for 3 months --> usually due to a PREGNANCY

i.e. the FIRST step in management of a woman w/ amenorrhea?
