Placental Pathology and Spontaneous Pre-Term Labor |
|
Definition
- Placenta previa --> When uterus contracts, puts pressure on the placenta and induces bleeding
- Placental abruption --> Normally implanted placenta separates from the wall of the uterus
- Vaginal bleeding --> Blood coming out is mom's --> Region where blood is flowing can't heal --> Reduced blood flow to baby
- Bleeding produces thrombin which is a potent activator of labor |
|
|
Term

|
Definition
- Previous preterm birth
- Cocaine use
- Smoking
- Extremes in maternal age --> Very young or very old
- African-Americans
- Inadequate prenatal care

|
|
Term
|
Definition
- Onset of labor is a molecular collaboration between mother and baby
1. Pituitary and Adrenal Axis
- Adrenal gland is one of the last fetal organs to develop
- Once adrenal gland is formed --> Produces enough glucocorticoids to stimulate labor
- Placental CRH is also key --> Secreted into maternal and fetal circulation
- CRH stimulates ACTH --> More glucocorticoids to be produced by maternal and fetal adrenals
- Maternal effects --> Adrenal production of glucocorticoids and DHEA-S
- Fetal effects --> Adrenal production of glucocorticoids for lung surfactant and DHEA to promote uterine contractility
- Preterm labor occurs when premature elevation of CRH and glucocorticoids occurs
2. Progesterone and Uterine contractions
- Change in myometrial progesterone receptors --> Become resistant to progesterone
- Altered progesterone metabolism |
|
|
Term
|
Definition
- Determined by the placenta
- Assures that fetus is ready for extrauterine life

2. Interrupt myosin phosphorylation

- 20% present in older postmenopausal women --> 80% younger women
- Non-estrogen dependent tumors
- High grade/more aggressive tumors
- Papillary serous carcinoma --> High grade carcinoma --> May present with myometrial and lymph node involvement |

Term
Pathology of Pelvic Inflammatory Disease (PID) |
|
Definition
- Etiology: STDs, pre-pubertal, post-abortion, or post instrumentation procedure
- 2-7 days: Acute inflammation with vaginal exudate is present --> Ascending spread to tubo-ovarian region --> Acute suppurative salpingitis
- Days to weeks: Fimbria of fallopian tubes seal off the opening --> Become adherent to ovaries --> Pyosalpinx, salpingo-oophoritis, and tubo-ovarian abscesses |
|
|
Term
Pathology of Chronic Endometritis |
|
Definition
- Etiology: Chronic PID, postpartum, intrauterine device (IUD), tuberculosis, and non-specific
- 15% due to Chlamydial infection
- Histology: Lots of plasma cells seen within the stroma
- Actinomyces infections are highly associated with IUD implantation
- Typical non-caseating granuloma formation with TB infection |
|
|
Term
|
Definition
- Malignant mesenchymal tumor of the uterus
- Really disorganized structure
- Less well circumscribed mass
- Nuclear and cytologic atypia present
- Lots of strange mitotic figures
- Any central necrosis is always malignant |
|
|
Term
|
Definition
- 50% subsequent to molar pregnancy, 25% subsequent to spontaneous abortion, 2.5% subsequent to ectopic pregnancy and 22.5% subsequent to normal pregnancy
- Highly malignant tumor of placental origin --> Cytotrophoblast and syncytiotrophoblast derived
- No villi are present
- Produces hCG
- Primary tumor in the uterus may regress quickly and may only present with metastatic disease
- Treatment: Chemotherapy --> Extremely responsive |
|
|
Term
|
Definition
- 12 months of amenorrhea
- Symptoms result from estrogen withdrawal
- Premature ovarian failure/insufficiency: Menopause before the age of 40 |
|
|
Term
Premature Ovarian Failure |
|
Definition
- Etiology: 90% idiopathic, genetic defects (Turner's syndrome, etc), ovarian toxins (chemo, radiation, mumps or CMV), autoimmune disease, or abnormal follicular stimulates (FSH receptor mutations)
- Evaluation: FSH, hCG, prolactin levels, thyroid hormone analysis, adrenal analysis, karytoyping, FMR1 premature screen, and baseline DEXA (bone) scan
- Treatment: Psychosocial support, prevention of osteoporosis (HRT, DEXA scans, weight bearing exercise, and supplementation), monitoring thyroid and adrenal function, contraception, and IVF if fertility is desired
- Patients with premature ovarian failure and much more likely to develop thyroid and adrenal failure --> Need yearly TSH and adrenal hormones
- 5-10% of POF patients will actually conceive naturally due to spontaneous ovulation --> Need contraception if pregnancy is not desired
- Donor oocytes if pregnancy is desired |

Term
Epidemiology of Menopause |
|
Definition
- Average age --> 51.4
- Presents earlier in Latina women and later in Japanese-American women --> Possibly due to the increased soy consumption by Japanese
- Presents about 2 years earlier in smokers
- Presents earlier in nulliparas and regularly cycling women
- Symptoms can vary throughout cultures
- Menopause is a happy time in African culture but is a terrible thing that women have to go through in the US |
|
|
Term
|
Definition
- Follicular depletion in the ovary --> Precipitous loss ~ age 38-40 years
- Fall in inhibin B concentrations --> Risk in serum FSH levels
- Estradiol secretion intially is normal or high but declines over time --> Increased FSH levels initially stimulates lots of estradiol production
- Changes in CNS responsiveness --> Stimulation of Chemothermal zones --> Hot flashes |
|
|
Term
|
Definition
- Vasomotor symptoms --> Hot flashes (75%), night sweats, and sleep disruption
- Amenorrhea or oligomenorrhea
- Vaginal and breast atrophy with urinary symptoms
- Decreased bone mineral density --> Increased risk of osteoporosis and fracture risk
- Cardiovascular changes --> Increased risk of atherosclerosis --> Estrogen is cardio protective |
|
|
Term
|
Definition
1. Vasomotor symptoms: Estrogen supplementation with intermittent progesterone is uterus still present, SSRIs, gabapentin, and clonidine
- Hormone replacement therapy shows the highest efficacy when initiated shortly after menopause (within 10 years)
- Bioidentical horomones: Hormone cream compounded based on individual salivary levels of estrogen and progesterone --> Individualized so very expensive and not recommended by professional societies
2. Vaginal dryness: Vaginal estrogen preparations, lubricants, and ospemifine (vaginal SERM) --> Agonist in the vagina but antagonist in the breast and uterus so no increased risk of breast/uterine cancer
3. Decreased bone density --> Assess bone mineral density via DEXA and treat based on risk |
|
|
Term
|
Definition
- Low bone mass and microarchitectural deterioration
- Increase in bone fragility and susceptibility to fractures
- Epidemiology: 1.5 million fractures/year --> Costs $17 billion/year --> 1:3 lifetime risk for vertebral fracture and 1:6 lifetime risk for hip fracture in white women >50
- 1/10 - 1/5 of women with a hip fracture die within a year
- 1/4 of these patients end up in a nursing home permanently
- T score: SDs between patient and average peak young adult
- Z score: SDs between patient and average bone mass for same age and weight
- Osteoporosis: T score <-2.5
- Osteopenia/low bone mass: T score -1 - -2.5
- Fracture risk doubles with every SD decrease
- Evaluation: Dual-energy x-ray absorptiometry (DEXA) bone scan --> Scans spine and hip to predict fracture risk and monitor therapy |
|
|
Term
|
Definition
- Weight bearing exercise
- Quitting smoking
- Dietary modification --> Increase calcium and vitamin D intake
- Medications: Bisphosponates (first line), selective estrogen receptor modulators, and estrogen replacement therapy
- SERMs are generally not well tolerated because they cause serious hot flashes
- Monitor therapy with DEXA of spine/hip |

Term
Female Sexual Dysfunction |
|
Definition
- 40% of women report sexual complaints
- 12% (1 in 8) have a sexual problem associated with distress
- Forms: Lack of sexual desire, impaired arousal, inability to achieve orgasm, and pain with sexual activity
- Vaginal dryness, dyspareunia, low desire and decreased arousal are more common after menopause --> More common in early menopause and normalizes over time |
|
|
Term
Treatment for Femal Sexual Dysfunction |
|
Definition
- Tailor management to the sexual problem
- Assess for conditions that alter sexual function
- Suggest lifestyle changes, sex therapy or psychotherapy
- Postmenopausal vaginal dryness --> Vaginal estrogen preparations, lubricants and ospemifene
- Postmenopausal women with hypoactive sexual desire --> Testosterone trial (very experimental)
- Arousal or orgasm disorder due to SSRIs --> Phosphodiesterase inhibitor |
