Q

Ectopic pregnancy

A

RF = Previous ectopic / PID / Surgery to fallopian tubes / Coils / Old age / Smoking

Presentation - typically 6-8 weeks gestation with missed period - constant lower abdo pain (RIF / LIF), Vaginal bleeding, abdominal tenderness +/- pain radiation to the L shoulder
O/E bimanual palpation reveals cervical motion tenderness

!TIP - always ask about anemia symptoms e.g dizziness, syncope etc

Investigation
* * Pregnancy test - Women may have a +ve pregnancy test. Normally HCG doubles every 48hrs so a rise <63% after 48 hours indicates an ectopic (a fall of >50% indicates miscarriage)
* Gold standard =** transvaginal ultrasound**

USS will show a ‘blob/bagel’ sign which does not move with the ovaries- gestational sac containing a yolksac or fetal pole in the fallopian tube

Q

Management of Ectopic pregnancy

A
  1. Expectant management - if <35mm unruptured ectopic with no visible heartbeat, no significant pain and HCG <1500
  2. Medical management (Methotrexate IM) - if HCG < 5000 & same as above
  3. Surgical management (Salpingectomy 1st line, Salpingotomy if risk of infertility)- if pain, adnexal mass >35mm, Visible heartbeat or HCG >5000

!NOTE - rhesus -ve women having surgical removal need Anti-D prophylaxis

Q

Miscarriage

A

Sx = Painless vaginal bleeding

Types;
* Threatened = vaginal bleeding with closed cervix but alive fetus
* Inevitable = Vaginal bleeding + open cervical os
* Incomplete = Retained products of conception after miscarriage
* Complete = gestational sac present but no embryo

Investigations;
1. 1st line = **Ultrasound **

Q

Features to look for on USS in early pregnancy + indicators of miscarriage

A
  1. Mean gestational sac diameter - *should be >25mm - this is when you would expect to see a fetal pole
  2. Fetal pole + crown rump length - this should be 7mm - this is when you would expect to see a heartbeat
  3. Fetal heartbeat - Pregnancy is viable when heartbeat is visible

Note - if no fetal pole is seen but sac >25mm then repeat scan in 1 week before confirming miscarriage. Also if crown-rump length >7mm but no heartbeat or crown-rump length <7mm with a heartbeat repeat in 1 week before confirmation.

Q

1967 Abortion act / 1990 Human Fertilisation + Embryology act

A
  • 24 weeks is the latest gestational age where abortion is legal
  • A woman can abort <24 weeks if continuing pregnancy involves greater risk to physical/mental health of the woman or existing children of the family
  • A woman can abort at any time in pregnancy if continuing the pregnancy is likely to risk the life of the woman or cause grave physical/mental effects OR the child is at substantial risk of severe handicap

2 registered medical practitioners must sign. Must be carried out by registered practitioner on NHS hospital or premise.

Q

Medical ToP

A
  • Most appropriate earlier in pregnancy. uses a combination of
    1. Mifepristone (anti-progestogen) - relaxes cervix
    2. Misoprostol (prostaglandin analogue) - taken 2 days later. Stimulates uterine contractions. Every 3 hours until expulsion is achieved.

Q

Hyperemesis gravidarum

A

Diagnosis = Protracted N&V + >5% weight loss or Dehydration or Electrolyte imbalance

Severity = assesed using the PUQE

Management;
* Antiemetics - 1st line is prochlorperazine, then cyclizine/promethazine, then ondansetron, then metaclopramide

* Fatigue
* Dark urine + pale stools
* Jaundice

Investigations -LFTs show hepatic picture with raised ALT, AST and GGT (ALP will also rise but this is normal in pregnancy)

* Many are asymptomatic
* Painless vaginal bleeding - typically 36+ weeks

Grading;
1 - placenta is lower than uterus but not reaching internal os
2 - Placenta reaches but does not cover internal os
3 - placenta is partially obstructing internal os
4 - Placenta is completely covering internal os

Invx = usually picked up on 20 week anomaly scan

Management;
- Repeat USS at 32 + 36 weeks

Q

Placental abruption

A
  • When the placenta separates from wall of uterus during pregnancy resulting in antepartum haemorrhage

Presentation
* Sudden & severe abdo pain
* Vaginal bleeding
* Shock (hypotension + tachycardia) - *pt may have no clear sign if concealed abruption.
* CTG abnormalities

O/E the pt may have a “woody” appearance to the abdomen (suggesting haemorrhage)
Invx; largely a clinical diagnosis - Can do USS to rule out praevia as a cause of bleed

Management;
* If < 36 weeks + fetal distress = C section (if not fetal distress just monitor)
* If > 36wks = vaginal delivery or C section if fetal distress

*NOTE - ensure to give maternal corticosteroids if delivering < 34 weeks + give Anti-D prophylaxis if woman is rhesus -ve.

Q

Placenta accreta

A

Where the placenta implants deeper into the myometrium (makes it difficulte to deliver the placenta)

Typically asymptomatic but may present with some bleeding in 3rd trimester.
Diagnosis = picked up on USS or at birth when placental delivery is difficult. MRI can be used to asses depth and width of invasion.

Mx;
* Planned C secrion between 35 - 36 + 6 weeks (give corticosteroids)
* If extensive disease then hysterectomy may be recommended during surgery or can try and do uterus preserving surgery.

If natural birth (i.e was not pre diagnosed) but delayed placental delivery pt may need hysterectomy.

1. Rupture of membranes followed by
2. Vaginal bleeding and
3. Fetal distress

Diagnosis = Sometimes picked up antenatally with USS. Often presents during labour with vaginal bleeding or during vaginal examination.

Mx = Carries v high fetal morality due to risk of asphyxiation or hypoxia.
If pre-diagnosed then Elective C section at 34-36weeks (+ corticosteroids).

145
Q

Nobathain cysts

A

Fluid filed csysts on the surface of the cervix. Usually up to 1cm in size.

152
Q

Androgen insensitivity syndrome

A

Condition where cells are unable to respond to androgen hormones due to a lack of androgen receptors.

160
Q

Signs & Symptoms in endometrial cancer

A

Postmenopausal bleeding is endometrial cancer until proven otherwise.

  • Postcoital bleeding
  • abnormal vaginal discharge
  • instrumental bleeding
  • haematuria
  • anemia
  • Raised platelet count
161
Q

Investigations for endometrial cancer

A

2ww referal for Transvaginal USS if;
* postmenopausal bleeding >12m after last period
* Age >55yrs with unexplained vaginal discharge, visible haemturia, raised platelets, anemia or raised glucose.

Transvaginal USS = to assess endometrial thickness (should be<4mm)

164
Q

What are the risks associated with HRT

A

Endometrial cancer (only if oestrogen-only HRT)
VTE
Stroke + CAD
Ovarian cancer

*NOTE. -The risks are not increased in women <50yrs & there is no risk of endometrial cancer in women without a uterus.
Oestrogen only HRT does not inc risk of CAD.

165
Q

MOA & SE’s of Clonidine

A

Alpha-2 adrenergic receptor agonist

It lowers BP and HR & is helpful for vasomotor symptoms + hot flushes

SE = dry mouth, headaches, dizziness, fatigue. Sudden withdrawl may result in rapid BP increase.

166
Q

Steps to choosing the most suitable HRT

A
  1. Do they have local or systemic symptoms? - local can be treated with topical oestrogen
  2. Do they have a uterus? no uterus = oestrogen only. Uterus = combined for endometrial protection (mirena coil licensed for 4yrs)
  3. Have they had a period in the past 12 months? perimenopausal = cyclical combined HRT with breakthrough bleed, postmenopausal = continuous.
167
Q

Side effects of HRT

170
Q

COCP

A

99% effective with perect use (91% with typical use)
Licensed up to age 50yrs.
Usually has a breakthrough bleed

MOA = Prevents ovulation, thickens cervical mucus + inhibits the proliferation of the endometrium.

Options;
1. 1st line contraceptive = microgynon or leostrin (as levonorgestrol has lower VTE risk)
2. 1st line for premenstrual syndrome = Yasmin continuous use (drospirenone has anti-androgen & anti-mineralocorticoid activity so helps with bloating + mood changes)
3. 1st line for Acne / Hirtuism = Dianette (cyproterone acetate hs anti-androgen effects - but higher VTE risk so stop after 3 months)

171
Q

Contraindications to the COCP

A
  1. Uncontrolled HTN (>160/100)
  2. Migraine + aura
  3. VTE history / vascular disease / IHD / Cardiomyopathy / AF
  4. Age >35yrs + Smokes >15 per day
  5. Liver cirrhosis or tumours
  6. SLE & Antiphospholipid syndrome
  7. BMI >35
172
Q

173
Q

POP

A

99% effective (91% with typical use)
Much fewer contraindications - only UKMEC4 is active breast cancer

Types;
1. Traditional POP (e.g norgestron) - doesn’t inhibit ovulation, cannot be delayed >3 hours
2. Desorgestrel (e.g cerazette) = can be taken 12hrs later

MOA = inhibits ovulation, thickens cervical mucus, inhibits proliferation of endometrium + reduces ciliary action in fallopian tubes

SE’s: 40% have regular bleeding and 40% have troublesome bleeding. Breast tenderness, headaches, acne.
Increases risk of ovarian cysts, ectopic pregnancy _ breast cancer.

174
Q

Advice for additional contraception when starting the POP

A

Day 1-5 = immediate protection
Day 5+ = additional contraception for 48hrs.

If starting a POP when currently on COCP - best to change on day 1-7 of hormone free period as no additional contraception needed. If switching when taking the active pills then additional contraception needed for 48hrs.

175
Q

Progesterone Depot

A

99% effective but 94% with typical use.
Injection every 12 weeks (ideally day 1-5 as immediate protection, if not 7 days extra protection required)

Contraindications: UKMEC4 is breast cancer.
Heart disease, vaginal bleeding, liver cirrhosis etc all contraindications too.

SE = May take up to 12months for fertility to reutn. Weight gain, acne, bleeding, osteoporosis (not licensed in women >50yrs)

Beneftis = improves dysmenorrhoea + endometriosis symptoms. Also reduces risk of ovarian + endometrial cancer.

176
Q

Progesterone implant

A

99% effective.

Pros = no restrictions for use in obese pts or those with VTE risk. no effect on bone mineral density and can make periods stop altogether.
