Ax Gynae Flashcards
What’s primary dysmenorrhea
Lower abdominal or pelvic pain with or without radiation to back or the legs ,with initial onset 6 TO 12 MONTHS AFTER MENARCHE. Pain typically lasts for 8-72 HOURS and usually occur at the onset of menstrual flow.
Associated symptoms - back pain,headache,diarrhea,fatigue,nausea,vomiting.
To diagnose primary dysmenorrhea other causes has to be excluded like leiomyoma ,endometriosis. Etc
How to treat primary dysmenorrhea
First line is NSAIDS
Secondly hormonal contraceptives( oral,vaginal or intrauterine) but effectiveness is limited.
But if someone needs contraception as well as dysmenorrhea ,first line could be a 2-3 month trial of OCP.
What’s primary amenorrhea
Absence of menses after age of 16 in presence of normal growth and secondary sexual characteristics.
13-14 in the absence of secondary sexual characteristics
In case breast budding occurs before age of 10, amenorrhea is defined a absence of periods within next five years.
What’s are stages of normal puberty
Thlarche
Pubarche
Menarche
Breast above tanner 2 stage indicates commencement of puberty and exposure to estrogen.
What’s menorrhagia
A from of abnormal uterine bleeding ( AUB )
Periods lasting more than 7 days and/or involving blood loss more than 80mL.
Normal periods lasts for 3-6 days and blood loss less than 80mL.
Two types of AUB
1.ovulatory- abnormal volume of length of bleeding at REGULAR INTERVALS.
2. Anovulatory - irregular and unpredictable
Causes of ovulatory pattern
UTERINE problems such as
1. leiomyoma
2. endometriosis
3. adenomyosis.
4. polyps.
Causes of anovulatory patterns
HORMONE problems such as
1. PCOS
2. hypothyroidism
3. hyperthyroidism
4. hyperprolactinemia
5. cushing syndrome.
How to assess if the pattern of bleeding is non specific in AUB patient
Assess the patients as having irregular bleeding because pattern includes investigations for endometrial hyperplasia for more diagnostic safety.
In reproductive age with AUB what’s the first concern
Pregnancy ( regardless of the pattern)
Which USS to do if ovulatory AUB
Transvaginal scan is more accurate for imaging of uterine abnormalities.
What’s the next step if any abnormalities in endometrium
Endometrial curettage and biopsy
When to arrange LH and FSH in AUB
Hormone assays like LH, FSH, prolactin should be done in a Anovulatory AUB, where hormone derangements are the Morse imp underlying cause to consider.
What’s infertility
Inability for a couple to conceive after 12 MONTHS of regular unprotected sexual intercourse in women LESS THAN 35 YEARS and after 6 MONTHS of sex in women of 35y or older.
In general what’s the most influential factor for infertility
Advancement of age.
Risk factors of carvical cancer
COCs reduce the risk of
1.Ovarian cancers as they cease ovulation.
- Endometrial cancer by 30%. By suppression of endometrial proliferation.
- Also colorectal cancer risk reduced in 15-20% by reducing bile acids in women on COCs.
Which ca has most risk with COCs
Cervical cancer
Less than 5 years use - 10% increased risk
5-9 years use - 60% increased risk
More than 10 y use- doubling of risk.
Also has a slight risk on breast cancer.
Benefits of preventing unwanted pregnancy and its harms, outweigh the slight increased risk of breast cancer associated with COCs.
Why does atropic vaginitis occur
From estrogen deficiency.
Symptoms - itching burning dryness and irritation all of which can relate to dyspareunia.
Also estrogen reduction alters vaginal flora leading to bacterial overgrowth. This can cause bacterial vaginosis and vaginal discharge.
Main treatment of atropic vaginitis
Estrogen cream
As they will take some time to be effective ,lubricant cream for sexual intercourse recommended.
How to treat vaginal candidiasis
Anti fungal agents
Presentation - itching , burning , dyspareunia, INFLAMED VAGINA WITH OR WITHOUT CHEESY WHITE VAGINAL DISCHARGE
Why use tropical antibiotics
Eg metronidazole is used for CONCOMITANT bacterial infection or vaginosis in atropic vaginitis.
What are absolute risk factors for COCP use
Is breast cancer a RF for COCP use
Breast cancer his in yourself is a RF but family history of breast ca isn’t a risk factor.
Is obesity a RF for COCP use
Obesity or overweight alone isn’t a RF. But if it’s with other cvs or systemic illness it could be a RF.
What’s the commonest cause of vaginal bleeding / post costal bleeding in post menopausal women
Atropic vaginitis due to ongoing estrogen deficiency
Wat are causes of iregular uterine bleeding
What’s the guideline for post coital bleeding in post menopausal women
Should investigate with a co-test of HPV AND LBS ( liquid base cytology ) and urgent referral to gynecologist to rule out cervical cancer.
Commonest cause of primary amenorrhea
Gonadal dysgenesis such as Turner’s syndrome
Secondly mullerian agenesis
Features of mullerian agenesis
Normal height
Secondary sexual characteristics
Body hair
External genitalia
But vagina is either absent or present as a short blind ended structure without cervix at vaginal apex.
Normal 46XX Karyotype with normal hormonal profile.
Normally nonfunctional uterus but rarely uterus with functioning endometrium( periodic cyclical abdominal pain with blood accumulation in vagina,cervix or uterus.)
Commonest menstrual abnormality with hyperthyroidism
Oligomenorrhea and amenorrhea
Less commonly menorrhagia.
Common cause for non- menopausal hot flushes
Hyperthyroidism
Hypertension is another cause.
How does hyperprolactinemia causes secondary amenorrhea
By inhibiting GnRH from hypothalamus
Average age of normal menopause
50-51 years
What’s Primary ovarian insufficiency ( POI) / Premature overran failure ( POF )
Ovarian failure BEFORE 40 YEARS of age.
1.Features of secondary amenorrhea
2. symptoms of estrogen deficiency ( decreased libido and atropic vaginitis)
3. high levels of FSH ( in menopausal range)
before the age of 40 years.
How to diagnose POI/ POF
Serum FSH levels
2 values of FSH in menopausal range ( >40 U/L) measured at least 1 month apart is diagnostic of POI
Parellel serum estradiol is needed and it is reduced
Treatment of POI/ POF
all women with POF should be started with menopausal hormone replacement therapy ( HRT)
To prevent menopause complications this should be continued at least till average age of menopause 50-55 yrs
- HRT doesn’t provide enough contraception for both POF and actual contraception. Therefore additional
Possible causes of secondary amenorrhea
Asherman syndrome.
Hormone abnormalities like pituitary tumor, hyperprolactinemia , ovarian insufficiency, PCOS.
Commonest risk factors of endometrial hyperplasia
Virtually always result from chronic exposure of endometrial tissue to estrogen ( unopposed but the counterbalancing effect by progesterone)
NEAT DOLL BC
What’s Depo Provera
It’s an injectable progesterone.Counterbalances the effects of estrogen and protective against endometrial hyperplasia
If first two lines failed to manage secondary dysmenorrhea what to do
Assess for possible causes such as endometriosis, leiomyoma, polyps and other pelvic pathologies.
What’s cervical ectropion
Single layer of columnar epithelium of the endocervix extended onto the ectrocervix and is exposed to trauma during coitus.
Common causes of post coital bleeding
<30 years - cervicitis and ectropion are commonest causes
In reproductive age (30-40) - cervical polyp is also a cause
How to approach primary amenorrhea
Diagnosis approach depends on presence or absence of secondary sexual characteristics.
In absence of such characteristics - hormonal studies including FSH ,LH ,TSH, prolactin.
In presence of characteristics - pelvic uss for uterine of menstrual outflow abnormalities.
Features with hypogonadotropic hypogonadism
Low body weight
Excessive physical exercise
Starvation
Seen is anorexia or bullemia nervosa.
It can present in primary or secondary amenorrhea.
what are checked By USS in primary amenorhea
- presence or absence of uterus
- mullerian features
- ovaries
- presence of transvaginal septum
- evidence of menstrual flow obstrucion
common etiologies of primary amenorhea
What’s the cardinal common feature of turner syndrome
Short stature and square appearance.
What are the causes of secondary amenorrhea that can present as primary amenorrhea
Pregnancy
Hypoparathyroidism
PCOS
Diabetes
Exogenous androgen use
Features of gondal dysgenesis, androgen insensitivity, HPO failure, Mullerian dysgenesis, transverse vaginal septum
How to asses bone age in CGD
X-ray of left hand and wrist to assess skeletal mutations.
In CGD bone age lags behind chronological age.
Which contraceptive is associated with Otosclerosis
COCP worsens otosclerosis specially if patient has experienced onset with the pregnancy or steroid use.
Non hormone methods (IUCD ) can be used in such instances.
Only indication to start HRT in menopausal women
Troublesome Vasomotor symptoms of menopause.
If HRT is not appropriate due to any reason next step is SSRI or SNRI
Window of emergency contraceptive methods
5 days or 120hours
Earlier the better.
No medical contraindications to the use of emergency contraceptive pills.
Management of cervical neoplasia in pregnancy
LSIL ( CIN 1) - same way as non pregnant women. Repeat after 12 months.
HSIL ( CIN 2,3) - referred for colposcopy. ( pregnant or non-pregnant)
If colposcopy is inconclusive what’s the next step
Should do cone biopsy.
What are suggested by cervical motion tenderness ( aka cervical excitation , chandelier’s sign)
Suggest a pelvic pathology
Classically PID or ectopic pregnancy.
If PID is suspected empirical antibiotics started after cervical swabs are taken.
If ectopic suspected next best step is to do pregnancy test and USS to exclude EP.
