28
Q

Next step CIN 1

A

Follow up without Tx by doing pap smear at 6 months or colposcopy

29
Q

Next step CIN2

A

Colposcopy at 6 months & at 12 months

30
Q

CIN3 next step

A

Conization of the cervix

loop electrosurgical excision

31
Q

When is HSIL cytology is preceded with HSIL (CIN2,3), what is Tx?

A

Diagnostic excisional procedure

32
Q

Women with subtotal hysterectomy OR total one for malignant cause (or benign cause but HPV positive) need what?

A

Routine swab of cervix or vaginal vault

33
Q

36 y/o woman has atypical glandular cells of undetermined significance. Next step?

A

Colposcopy with endocervical curettage

34
Q

When should women be tested for HPV DNA

A

When a pap smear shows ASCUS in women under 30 y/o

35
Q

If ASCUS is found:

A

HPV test OR repeat cytology in 6 months

HPV - = repeat cytology in 12 months
HPV + = colpo

If cytology is chosen instead of test:
ASCUS = colpo
- = repeat cytology again in 6 months

36
Q

Tx for Lichen sclerosus?

A

Fluorinated corticosteroid

37
Q

Ulcers in sexually active person denote one of:

A 
HSV
Primary syphilis
Chancroid
Lymphogranuloma venereum
Granuloma inguinale
38
Q

HSV cytology:

A

Multinucleated giant cells.

Epithelial cells containing nuclear inclusion bodies

39
Q

30 y/o woman: type 1 diabetic, non offensive vaginal discharge, itching, red and swollen genital area.
test and result?

A

Wet mount test: pseudohyphae and spores.

40
Q

Most common species causing candidiasis?

A

C. albicans

41
Q

31 y/o woman: vaginal discharge, odor, itching, yellow discharge, vulvar and vaginal erythema, strawberry cervix.
Dx?

A

Trichomonal vaginitis.

42
Q

Once ovarian torsion is confirmed, what should be done?

A

Conserve ovary via a speedy detorsion

43
Q

Suspicions of PCOS as patient displays risks for it. What screening test to do?

A

Lipid levels

HbA1C

44
Q

How to prevent congenital rubella syndrome

A

Ensuring a patient’s rubella antibody titre is greater than 10 IU/ml. If she is non reactive, immunization should be deferred until after delivery due to inability of rubella vaccine virus to cross placenta and infect the fetus

45
Q

When should high risk pregnant patients be screened for DM

A

If they test negative in initial screening, they should be screened again towards the end of second trimester between 24th & 28th weeks

A

False

Methyldopa is safe

47
Q

Pregnant woman with mild preeclampsia at 37 weeks gestation. Next step?

A

Vaginal examination and calc of Bishop score.
Bishop score 6: labour should be induced
Lower score: cervix should be ripened first

48
Q

Late decelerations are consistent with what?

A

Uteroplacental insufficiency.

Management should include intrauterine resuscitation first. If no improvement, delivery.

49
Q

3rd stage of labour?

A

Delivery of placenta. If placenta isnt delivered by 30 mins, Dx of retained placenta.

Mgm of Retained placenta: uterotonics + watchful waiting and/or cord traction for 15 mins.

50
Q

Tx of women in pre term labour

1- tocolytic agent (CCB) IF they are having contractions
2- Glucocorticoid to avoid RDS in neonate
3- Antibiotics to avoid GBS

Q

How is Tocolytic therapy useful?

A

In delaying delivery up to 48h in situations of pre term labour with contractions to allow max benefit of glucocorticoids to avoid RDS in neonates. In pts in pre term labour <30 weeks, prostaglandin synthetase inhibitors i.e. indomethacin are 1st line tocolytics

52
Q

Oral progesterone pill
Any contraception that includes estrogen isnt recommended since estrogen reduces breast milk production.

  • Prior uterine surgery
  • Prior classic CSXN
  • Cardiac Dx
  • Birth canal obstruction
  • Maternal death
  • Cervical cancer
  • Active genital herpes
  • HIV viral load > 1000

Fetal:

  • Acute fetal distress
  • Malpresentation
  • Cord prolapse
  • Macrosomia
  • Placental abruption
  • Placenta previa
  • Passenger pelvic disproportion
55
Q

Oligohydramnios is associated with which fetal condition?

A

Talipes equinovarus (club foot)

58
Q

A

1- Threatened: presents with vaginal bleeding +/- cramping, cervix is closed, Ultra sound shows viable fetus

2- Inevitable: Vaginal bleeding, crampy pelvic pain, cervix is dilated.

3- Incomplete: extremely heavy bleeding & cramping. Passage of tissues may have been noticed, cervix is open.

4- Complete: history of bleeding & cramping, passage of placenta & sac, resolution of Sx, cervix is closed

5- Missed: no Sx, fetus died in utero, cervix is closed. U/S shows too small fetus & no fetal heart rate

6- Habitual: > 3 consecutive spontaneous abortions

7- Septic: infection of contents of uterus
