Menstruation + Infection Flashcards
Primary amenorrhea is defined as
Primary amenorrhea is the failure of menses to occur by age 15 years (some sources say 16 years), in the presence of normal growth and secondary sexual characteristics (breast development, axillary or pubic hair).
At age 13 years, if no menses have occurredand there is a completeabsence of secondary sexual characteristics, evaluation for primary amenorrhea should begin
MCC of secondary amenorrhea
Intrauterine pregnancy is the most common cause of secondary amenorrhea. The first step in the workup of amenorrhea should almost always be a pregnancy test.
17-year-old female who is concerned that she has not yet had her period. She is sexually active and uses condoms consistently. She does not use other forms of contraception. On physical exam, there is normal breast maturation. The uterus is not palpable, and this is confirmed by pelvic ultrasound. Karyotype testing is performed and returns as 46 XX. Her serum testosterone levels are within normal limits.
Primary amenorrhea
3-year-old female who is concerned that she has not had her menses over a period of four months. She is also very distressed about increased hair growth. She reports having to shave frequently above the lip, chin, chest, and lower back. Prior to this, she had regular menses. The patient’s weight is 168 lbs. (76.2 kg) and height 5 feet and 1 inch (154.9 cm). On physical examination, there is hair above the lip and chin area. She also has acne on her cheeks and forehead. Hyperpigmented plaques of the skin are found on the nape of her neck. Bilateral enlarged ovaries are palpated on pelvic examination. β-hCG is negative and LH: FSH is 3.
Secondary amenorrhea
MCC of primary amenorrhea
- Pregnancy
- Imperforate hymen
- Gonadal dysgenesis - Turner’s syndrome (46 XO) - short web neck
- Müllerian agenesis (absent uterus and vagina)
- HPO axis abnormalities - Anorexia, bulimia, weight loss, excessive exercise
Absence of menses for 3 months in a woman with previously normal menstruation or 6 months in a woman with a history of irregular cycles
Secondary amenorrhea
Labs for primary amenorrhea
- Quantitative βHCG
- FSH, prolactin, TSH, T3, Free T4 estrogen, progesterone
Excessive uterine bleeding and prolonged menses that is NOT caused by pregnancy or miscarriage, diagnosis of exclusion, look for an underlying endocrine disorder
Dysfunctional uterine bleeding
a 35-year-old woman with concerns about heavy menstrual periods for the past year that occur at irregular intervals. She explains that sometimes her menses come twice a month but other times will skip two months in a row. Her menses may last 7 to 10 days and require 10 to 15 thick sanitary napkins on the heaviest days. She admits to some fatigue, but she denies any lightheadedness. She has no pain with menses or intercourse and denies any vaginal discharge. She has had normal Pap smears in the past. She is in a stable monogamous relationship with her husband and denies a history of STIs. On physical examination, her blood pressure is 120/ 80 mm Hg and her body mass index (BMI) is 32. Her pelvic examination is normal.
Dysfunctional uterine bleeding
menses that occur more frequently (menses < 21 days apart)
Polymenorrhea
menses that involve more blood loss (> 7 days or > 80 mL) during menses
Hemorrhagic or hypermenorrhea
prolonged/heavy bleeding (>7 days or >80 mL); regular intervals
Menorrhagia
uterine bleeding that occurs frequently and irregularly between menses
Metorrhagia
more blood loss during menses and frequent and irregular bleeding between menses
Menometrorrhagia
Period = long intervals > 35 days
Oligomenorrhea
AUB in the absence of an anatomic lesion, caused by a problem with the hypothalamic-pituitary-ovarian axis
Dysfunctional uterine bleeding
Dysfunctional uterine bleeding dx
Diagnosis of exclusion, Uterine Dilation and Curettage is the gold standard diagnosis
- Urinary β-hCG levels—r/o pregnancy
- Labs: CBC, iron studies, PT, PTT, TSH, progesterone, prolactin, FSH, LFTs
- Progestin trial—if the bleeding stops, anovulatory cycles confirmed
- Ovulation journal, Pap smear
- Pelvic U/S, endometrial biopsy, HSG, hysteroscopy
- Urinary β-hCG levels—r/o pregnancy
Tx of dysfunctional uterine bleeding
a 19-year-old nulligravid college female who complains of dull, throbbing, cramping lower abdominal pain during menses for the past three years. She reports nausea and vomiting during menses but denies irregular or heavy periods, pain with intercourse, or abdominal pain outside of menses. Pain tends to peak 24 h after the onset of menses and subsides after 2 to 3 days. A pelvic exam is normal.
Dysmenorrhea
Refers to uterine pain around the time of menses, which can either be primary or secondary
Dysmenorrhea
S/S of primary dysmenorrhea
- Painful uterine muscle activity due to an excess of prostaglandins (F2a)
- Teens-early 20s, declines with age, no associated pelvic pathology
- Risk factors include menarche before age 12, nulliparity, smoking, family history, obesity
- Pain with menstruation, lower abdominal, intermittent, “labor-like” on days 1-3
- Nausea, vomiting, diarrhea (smooth muscle contraction), headache
- Normal pelvic exam
Tx of primary dysmenorrhea
Treatment: NSAIDs and oral contraceptive pills
Secondary dysmenorrhea mcc
- Painful menstruation caused by clinically identifiable cause
- Etiology: Endometriosis, adenomyosis, polyps, fibroids, PID, IUD, tumors, adhesions, cervical stenosis/lesions, psych
- Pain with menstruation begins mid-cycle and increases in severity until end
- Common women age (20-40 s)
Tx of secondary dysmenorrhea
Tx underlying cause
12 or more months of amenorrhea occurring at a mean age of 51 years
Menopause
the transition between reproductive capability and menopause hallmark is irregular menstrual function, lasts 3-5 years
Perimenopause
Onset of menopause < 40 years old
premature ovarian failure
FSH and estradiol levels of menopausal women
FSH and estradiol levels (FSH > 30) with ↓ estradiol (although not necessary for diagnosis)
Tx of menopause
-
Estrogens are used to treat hot flashes
- If uterus: HRT (estrogen + progesterone), if no uterus (ERT)
- Woman with an intact uterus should not use estrogen alone because of the increased risk of endometrial cancer
- Progestins: Hot flashes, increased risk of breast cancer
- HRT—severe menopausal symptoms (hot flashes, night sweats, vaginal dryness)
- “Smallest dose for shortest possible time and annual reviews of the decision to take hormones”
- HRT should not be used to prevent cardiovascular disease due to slightly increased risk of breast cancer, MI, CVD, DVT
- Hormone therapy effect on lipid profile: HDL and TG levels ↑, LDL levels ↓
Contraindications for HRT
- ↑ triglycerides
- Undiagnosed vaginal bleeding
- Endometrial cancer
- History of breast CA or estrogen-sensitive cancers
- CVD History
- DVT or PE history
Non hormonal therapies for menopause
Cool temperatures, avoid hot, spicy foods or beverages, avoid ETOH, exercise, soy
- Alternative drugs for vasomotor symptoms
- SSRIs (paroxetine)
- SNRIs
- clonidine
- gabapentin
Follicular (proliferative) phase of menstrual cycle
- The follicular phase is the first part of the menstrual cycle
- It goes from day 0 to day 14
- First, GnRH (from the hypothalamus) stimulates FSH and LH release (from anterior pituitary)
What causes ovulation
- Estrogen secretion is increased even more from the follicle in FOLLICULAR PHASE . It induces an LH spike, which causes ovulation
Which phase is 15-28 of the cycle
Luteal phase
What happens in the luteal phase
- After ovulation, the follicle becomes the corpus luteum, which secretes progesterone and provides negative feedback to FSH and LH
- If pregnancy does not occur, the corpus albicans is formed, which no longer secretes estrogen and progesterone
Which phase does endometrial sloughing or menses occur in?
- This decrease in hormones leads to endometrial sloughing or menses
- To begin a new follicular phase of the menstrual cycle, GnRH is secreted.
