Q

What is CIN and different stages and management

A

Dyskaryosis of cervical tissue - pre-invasive
CIN1 - lower 1/3
- most will regress spontaneously
CIN2 <2/3
CIN3 >2/3
- less likely to regress, more likely to progress to invasive squamous cell cancer and quickly in younger women

Smear : CIN2-3:
Inflammatory - repeat in 6m, do swab, colposcopy if 3x abnormal
Borderline dyskaryosis = HPV test. If pos = 6 monthly colposcopy, LLETZ if persistent
If neg = 3y screening

If mod or severe dyskaryosis = colposcopy + LLETZ, then smear and HPV test in 6m. Pos = colp again

Suspected invasion or abnormal glandular cells (adenocarcinoma of cervix) = urgent colposcopy

Colposcopy = visualise transformation zone, give acetic acid which is taken up by neoplastic cells = white = abnormal, then do punch biopsy. Also look for microinvaion - vascular abnormalities

Endometriosis, adenomyosis, adhesions

  • COCP may help if cyclical pain
  • GnRH course can predict success of hysterectomy

Mitelschmerz - mid-cycle menstrual pain in teenagers and older women around time of ovulation

Pelvic congestion: lax pelvic veins seen on laparoscopy get worse when standing or premenstrually.
- Deep post-coital ache

If hyperandrogenergic and testosterone >5, check 17-hydroxyprogesterone to exclude androgen secreting tumour

212
Q

Manage PCOS and long term consequences

A

Weight loss and exercise improve insulin sensitivity
Smoking cessation
Treat dyslipidaemia, hypertension, DM2

Metformin - increases insulin sensitivity in short term, reduces disturbance of menstrual and ovulatory function. Doesn’t cause weight loss
Clomifene - induces ovulation. Risk of multiple pregnancies, ovarian hypersensitivity (esp if assisted contraception) - monitor response on US for first cycle, ovarian cancer
Ovarian drilling needle point diathermy - reduces hormonal production. Risk of future preterm, large babies, gestational diabetes, pre-eclampsia

COCP to increase progesterone and decrease risk of endometrial cancer from unopposed oestrogen

Induce regular withdrawal bleed with norethisterone (/3m) if not on COCP to reduce risk of endometrial cancer

Treat hirsuitism with cyproterone anti-androgen cream

Long term = endometrial cancer, gestational and type 2 diabetes, CVS disease. NO increased risk of ovarian or breast cancer

3-7d after HCG, 12-17d after pregnancy ensues
Prevent with lowest level of gonadotrophs, may need to cancel next cycle

214
Q

Manage OHSS

A

Mild and moderate - bloating, mild/mod pain, ascites on US, ovary 8-12cm:

  • Analgesia - paracetamol (avoid NSAIDs as encourage shift from intra to extracellular space and renal impairment)
  • Avoid strenuous exercise - risk of torsion
  • Continue progesterone luteal support and avoid HCG
  • See fertility team every 2-3d

Severe - clinical ascites, haematocrit >45%, hypoproteinaemia, oliguria, ovary >12cm:

  • Admit, daily FBC/UE/LFT/albumin
  • Analgesia and anti-emetics
  • VTE - stockings and LMWH

Questions to ask in sterilisation - 6

A 
Other methods 
Consent of both partners
Who 
Irreversible
Failure
Side effects
258
Q

HPO in menstruation

A

Hypothalamus has pulsatile release of GnRH which stimulates ant pituitary to release gonadotrophs LH and FSH
These stimulate ovary to release oestrogen and progesterone which have negative feedback on hypothalamus and pituitary

259
Q

Process of menstruation

A

Day 1 = first day of menstruation. FSH levels high for 4 days, stimulating primary follicle to develop. This then make oestrogen which stimulates glandular proliferative endometrium and cervical mucus receptive to sperm (clear and stringy) and controls release of LH and FSH
By 14 days before end of cycle, oestrogen high enough to stimulate LH surge which stimulates ovulation. Primary follicle then becomes corpus luteum which secretes progesterone, preparing endometrium for implantation - convoluted glands in excretory phase, and makes mucus viscid hostile to sperm
If it doesn’t get fertilised in 14d, corpus luteum breaks down and hormone levels drop, stimulating spiral arteries in lining to constrict and shed lining
If it is fertilised = high levels of chorionic gonadotropin and embroil embeds in decidua

260
Q

How to delay ovulation

A

Norethisterone from 3d before bleeding due until to acceptable level
Or 2 packets of COCP with no break

261
Q

263
Q

Causes of subfertility in order - 5

A 
[UMATE]
Unexplained 
Male factor
Anovulation
Tubal
Endometriosis
264
Q

History and exam for subfertility

A 
Women:
- menstrual
- pain, sti
- surgery
Men:
- undescended testes
- mumps
- ed
Both:
- smoking
- alcohol
- children

Exam:

  • BMI - reduced fertility and cannot get trt
  • evidence of endocrine eg pcos
  • evidence of pelvic pathology eg endometriosis or fibroids
  • cervical smear if due, STI screen
265
Q

Investigate subfertility - primary and secondary care

A

Primary care:

  • baseline hormone profile - FSH and LH at start of cycle
  • progesterone surge 7d before menses (midluteal)
  • TSH, prolactin, testosterone
  • rubella
  • chlamydia
  • semen analysis - lifestyle changes and vit c supplements then reanalyse in 3m

Secondary care:
- TVUS for adnexal mass, submucosal fibroid, endometrial polyp, PCOS
- laparoscopy and dye test for tubal patency
- hysterosalpingogram with contrast and x-ray or sonogram with TVUS - dye into cervix for uterine and tubal abn
— chlamydia screen first and stat azithromycin

266
Q

Lifestyle modification for subfertility management

A

Alcohol, smoking

Sex 2-3x/w, not timed

267
Q

Management of subfertility in woman

A

Clomifene citrate - antioestrogen, increases FSH by negative feedback to pituitary
SE: ?multiple pregnancy, ovarian hyperstimulation - monitor with US, SE - labile mood, flushing
- 6-12 cycles (?ovarian cancer link)

Laparoscopic ovarian drilling for PCOS reduces LH and restores feedback mechanisms

Gonadotrophins if clomifene resistant or low oestrogen wth normal FSH

Metformin may stimulate ovulation in PCOS

Surgery: tubal catetherisation of hysteroscopic cannulation, but high rates of ectopic.
Treat endometriosis, adhesions (adhesiolysis)

268
Q

Indications and good prognosis signs for IVF

  1. Palpate size if <20w, measure SFH from 20w
  2. Number of foetuses
  3. Foetal lie - longitudinal, oblique, transverse
    - presentation = occipitoposterior, occipitoanterior or occipitotransverse
  4. Presentation - cephalic, breach
  5. Head engagement - /5 with Pawlik’s grip between lower pole of uterus

Watch patient’s face for pain

Difficult if: polyhydramnios, maternal size, tense abdo muscles

277

Reduced >28w = CTG
- if RF for IUGR, still birth or still reduced movements= US for growth, liquor volume and umbilical artery Doppler

279
Q

Effect of hormones in pregnancy on woman

A

Progesterone reduce smooth muscle excitability, relaxing gut, ureters and uterus. Also raises temperature
Oestrogen increases breast and nipple growth and fluid retention
Thyroid growth from colloid production
Prolactin increases throughout pregnancy

280
Q

A

CO increases from increase in SV and HR
Peripheral resistance falls from hormonal changes
Aorta-caval compression can reduce CO
BP (diastolic) decreases in 2nd trimester then back to normal by 3rd
Varicose veins
Vasodilation and hypotension = renin and angiotensin release for BP regulation

283
Q

Resp, GI, renal and skin changes in pregnancy

A

SOB, ventilation increases, maternal pCO2 lower to allow removal of foetal CO2
GI reduced motility so constipation and delayed emptying, and lower oesophageal sphincter relaxes = heart burn

18-22w: anomalies - cardiac, renal, neural tube
- skull shape and interior, spine, abdo, heart, arms and legs, face and lips
- fatal abnormalities are bilateral renal agenesis, some cardiac, some trisomy 18/13
Echo if high risk of cardiac abn eg hx, suspected abnormality, drugs, monochorionic twins

<28w - deliver at 26 degrees, don’t dry, put into plastic bag, place under heat, don’t cut cord for 3m, hold 20cm below introitus to increase haematocrit and reduces oxygen requirements and IVH but increases phototherapy need

308
Q

Definition of onset of labour

A

Contractions become regular and cervical effacement and dilatation become progressive
1 - onset of contractions
2 - cervical effacement and dilatation
3 - rupture of membranes
4 - descent of presenting part through birth canal

309
Q

Stages of labour

A

First - latent = irregular painful contractions, cervix effacing and dilates up to 4cm. Established = regular contractions from 4-10cm (0.5cm/h).
Takes 8-18h for primip, 5-12h for nullip
Monitor:
- foetal hr /15m
- contractions /30m - should be 3-4/10m, 1m each
- pulse /h
- assess dilatation and position of head /4h
- urine for ketones/protein /4h
- bp and temp /4h

Second

  • passive (if epidural, to reduce chance of instrumental delivery). Complete dilatation but no pushing.
  • active - pushing with abdo muscles and Valhalla manoeuvre. Use oxytocin if plateau. Should deliver within 3h of active phase starting
  • contractions /30m
  • pulse and bp /h
  • temp /4h

Third - placental delivery (1h), uterus contracts to <24w. Signs = lengthening of cord, rush of blood, uterus rises.
Can give ergometrine and oxytocin (syntometrin) once ant shoulder delivered - decreases PPH, need for transfusion and postnatal anaemia
- can cause MI, dont use in htn, pre eclampsia, liver or renal disease
- SE nv, headache

310
Q

  • premature
356
Q

Degrees of tear in labour and management

A

First - perineum skin only. Heals without stitches in a few days, can sting on urination
Second - includes perineum muscle and may extend into vagina. Will need stitches, heal in a few weeks
Third - extends to anal sphincter. Needs repair with anaesthesia, may cause faecal incontinence and painful sex
Fourth - extends to rectal mucosa, likely to need more specialised repair. Cause faecal incontinence and painful sex

Management:
Ice, warm water, sit on cushion
Laxatives, numbing spray
Tell doctor if persisting, severe or getting worse

357
Q

Diagnosis of transverse lie

A

A

Delayed 3rd stage - >30m to deliver

  1. Placenta adherens - myometrium doesn’t contract behind it
  2. Trapped placenta - trapped behind closed cervix
  3. Partial accretion - still embedded

If had rush of blood and lengthening of cord, rub uterus up and pull and twist cord
IV oxytocin if bleeding
May need surgical removal

Risks: infection, PPH

  • mild bleed - admit, do inv, high risk serial scans then CS at 37-38w
  • big bleed - raise legs, fluids, blood transfusion, CS, maintain UO

Placenta praevia - placenta in lower segment of uterus, covering os
- major or minor
- normally diagnosed at 20w scan. Scan again at 32w if major, 36w if minor

- soft and non tender uterus, painless bleed, can be heavy
- assoc with smoking, iugr, polyhydramnios, maternal age, fibroids, D&C
- if foetal head engaged = not praevia

Placenta abruption - placenta partially/completely separates from uterus before labour

  • painful, woody uterus, with contractions
  • foetal hr absent or distressed, normal lie
  • concealed or revealed, shock out of keeping with visible blood
  • DIC from thromboplastin release
  • assoc with pre-eclampsia and htn
  • CS if signs of distress

Vasa praevia - foetal vessels near/over os and can rupture
