O and G Flashcards
Post Pill Amenorrhoea
Normal : Amenorrhea up to 6 months / Wait for a spontaneous remission
If the patient is Anxious after 3 months : Give Clomiphene
After 6 months check USG for ovary for ovulation
Blood test for FSH LH and Oestrogen
Normal Levels :
- FSH 5-20 IU/L.
- LH 1.5-15 IU/L. ( Follicular Phase ) Up to 75 ( Peak of Cycle )
- Estrogen < 10 pg/mL.
- Prolactin :
Non-pregnant 2-30 ng/mL
Pregnant 10-210 ng/mL
Prolactinoma it’s supposed to be over 400 and
macroadenoma it is over 4000
Menopause and associated symptoms
menopausal woman with bleeding is always a sign of cancer - endometrial until proven otherwise.
Menopause + brown discharge—> endometrial cancer
Menopause + grey yellow purulent discharge —> infection
Menopause + painless bleeding after intercourse —> endometrial cancer Menopause + green discharge —> chalamydia
Bleeding within 1st yr of menopause —> follicular reactivation
sexually active / Menorrhagia / Dysmenorrhoegia or Fibroids not distroting the uterine cavity
Mirena IUS
If Mirena contraindicated
Assess for risk factors for OCP pills then give
If she has sickle cell anemia Then Depo will the first choice

Levo nelle pill 72 hr

If not suitable - Methyl dopa
Post menopausal bleeding is Cancer
especially endometrial cancer Until PROVEN otherwise
Transvaginal USG is the first line for endometrial thickness

Failure rates of different Contraceptive methods
Failure rates of different contraceptive methods:
A. Permanent methods: -
Vasectomy= 0.1% or 1:1000 -
Tubal ligation= 0.5% or 1:200
B. Temporary methods: -
Condom (male)= 95% effective and 5% chance of failure rate -
Condom (female)= 5% failure rate -
IUCD= 0.6% - IUS (Mirena contains levonorgestrel)= 0.1% -
POP (progesterone only pill)= 0.3%
Contraception failure rates & duration of use:
- IUS 0.1% to 0.4% (3-6 years)
- IUD 0.8% (10 years)
- Implant 0.1% (3 years)
- Injection 4% (3 months)
- COCP 7%
- POP 7%
- Patch 7% (once per week then 4th week stop for menses)
- Male condom 13%
- Female diaphragm 17-27 %
- Tubal ligation 0.5%
- Vasectomy 0.15%
Peri menopausal symptoms
With hypertension and controlled with ACEi or SMOKER = Can give HRT patch (Oestrogen transdermal no effect on thromboembolism )
But in OC pills (Oestrogen not given to Controlled hypertension )
However Patch = much less Thrombo embolism Than ORAL OESTROGEN
Treatment of Post-menopausal symptoms:
- Life-style modification.
- If there is a uterus: - Combined hormone replacement therapy (HRT). -
Another possible answer= transdermal estradiol and progesterone patches. - If no uterus (H/O hysterectomy) or if there is IUS in place: - Oestrogen only HRT. - This is because progesterone is given with oestrogen to protect the uterus against endometrial carcinoma.
- If post-menopausal woman is a smoker: - HRT is given as transdermal patch, as oral route has higher risk for venous thromboembolism.
Types of combined HRT:
A. Sequential “cyclical” combined HRT: -
Used in the first 12 months of menopause or in perimenopause “still menstruating”.
Oestrogen is taken daily while progesterone is taken cyclically for the last 14 days of a menstrual cycle.
B. Continuous combined HRT: -
Used in menopausal women who have had their last menstrual cycle 12 months ago.
Both oestrogen and progesterone are taken daily.
***Perimenopause= still menstruating but may be irregularly or heavily near the age of 50 +/- other vasomotor symptoms.
Myoma treatment
If doent want child then symptomatic
If want child and intra mural - Myomectomy (GNRH given to reduce size before operation but it inhibits ovulation )
asymptomatic … follow up
menorhagia … IUS ( if not distortion ) , NSAID ,, COCS
severe menorhagia .. ellanova surgery …
need child … myomectomy surgery ….
doesnt need child ,,, hysterectomy or endometrial ablation ( if small less 3 cm ) ##
GNRH agonist beforee surgery is indicated
Anti HTN in pregnancy: LMN –Labetalol –Methyldopa –Nifedipine
In severe preeclampsia 1- AntiHTN medication 2- Mgso4 to prevent eclampsia 3- CTG and USG to monitor the baby 4- If>34 weeks give steroids to stimulate surfactant production
deal with the cause (HTN!) before trying to prevent complications.

Lichen Planus Vs Vaginal Thrush
vaginal thrush(candidiasis):
white cheesy vaginal discharge +itching lichen sclerosis:
white plaques on anogenital skin+ itching at night
(tx:topical steroids,follow up 3 and 6 months because risk of scc of vulva)
lichen planus: white lacy pattern on oral mucosa
Ectopic Pregnancy management OB 1257
asymptomatic (with visible heart rate ) —>methotexae
stable symptomatic or/and visible heart rate —> laparascopy
unstable —->laparatomy
Anemia in pregnancy
If 33 weeks (U have enought 3 weeks time to correct anaemia with iron supplement)
but after 36 weeks Blood transfusion for quick refill (as there will also be blood lost during delivery )
1st trimester 1wk-13wk <11g/dl
2nd 14wk -26wk <10.5 3rd
27wk-40wk <10.5
postpartum <10
1unit to Blood Transfusion increases Hb by 10g/L.
Oral Ferrous supplements increase Hb by 10g/L in one week.
This is why after 36 wks BT is preferred, to have an adequate Hb level for delivery.
Panicillin allergy patient CS 0211 which ab to give Tri metho / Nitro furen Amoxi / Co amoxi Cefelaxime
DONT GIVE trimethoprim in 1st tri
DONT GIVE nitrofurantoin in 3rd tri
DONT GIVE ciprofloxacin at any time
Give Cefelaxime (10% coross reaction with penicilline but is avoidable )
Based on plabable info Safe in pregnancy:
HTN: labetalol, nifedipine, hydralazine
UTI: penicillin / amoxicillin; cephalosporin / cephalexin ; erythromycin (the rest macrolids CI); clindamycin
Malaria prophylaxis: chloroquine, proguanil, mefroquine

CI in pregnancy: Trimethoprim (I trimester) Nitrofurantoin (near term) All macrolids excepting erythromycin Quinolone / ciprofloxacin Tetracycline / doxycycline

Two types of HRT
Cyclical and Continuous
Perimenopausal —cyclic HRT
Post menopausal … >12 months… Continues HRT
Without uterous estrogen only
With uterous if compulsion .. give IUS with estrogen only
GY 4540 Endometrial ablation not Mirena
GY 4540 Endometrial ablation not Mirena
Diagnosis of PCOS CS 0040
Cannot be verified by Lab values
but usually the LHS and FSH levels will be on the BOderline maximum
and its ratio will be increased
the ratio of LH: FSH is more important and both may be raised.
Moreover, a diagnosis of PCOS does not depend on the levels of FSH/LH.
it depends on
- hirsuitism/ raised testosterone
- ultrasound criteria for PCOS and
- oligomenorrhoea or amenorrhoea
