Absent Uterus and Vaginal Agenesis
Malnutrition
When should you investigate Primary Amenorrhoea
at 14 with no breast development, or at 16
What causes Secondary Amenorrhoea
Ovarian Failure-Surgery, Radiotherapy, Chemotherapy and X chromsome disorders
Hypothalamic-Pituitary-Ovarian Axis Malfunction - Exercise, Stress and Weight Loss
Hyperprolactaemia- Hypothyroidism, renal/liver failure, drugs, pituitary tumours
Ovarian Caurses- PCOS and Ovarian Tumours
Uterine Causes - Pregnancy and Ashermans Syndrome
Treatment for Amenorrhoea
Manage cause - eg hypothyroidism, tumours, PCOS etc.
Ovarian failure - no treatment give HRT
Manage Lifestyle for axis dysfunction - gain weight, reduce exercise and reduce stress
Clomifene can encourage ovulation
COCP components
Ethinylestradiol + Norethisterone or Levonorgestrel
What gene mutation can increase risk of fibroids
Fumarate Hydratase (can also cause benign smooth muscle tumours of the skin and increase risk of renal cancer)
What is a fibroid
It is a benign smooth muscle tumour
What are the 4 types of Fibroids
Subserosal
Submucosal
Pedunculated
Intramural
What is a subserosal fibroid
A fibroid in the uterine wall bulging out under the visceral peritonium
What is a submucosal fibroid
A fibroid under the endometrium
What is an intramural fibroid
A fibroid in the muscular wall of the uterus
What is a pedunculated fibroid
A fibroid attached to the uterine wall by a peduncle
What are fibroids associated with
FH
increasing age
Afro-Caribbean
Gene mutation - Fumarate Hydratase
What are fibroids dependent on
Oestrogen
What causes fibroids to increase in size
Pregnancy or COCP
What causes fibroids to atrophy
Menopause
What are the symptoms of fibroids
asymptomatic menorrhagia and anaemia pain Abdominal mass if large Fertility problems
What investigations are used for fibroids
US or Hysterscopy
Treatment of fibroids
No treatment if asymptomatic
If causing menorrhagia but no other symptoms - IUS
GnRH or Ullipristal Acetate can be used to shrink fibroids prior to surgery but not long term use
Myomectomy - to remove fibroids
uterine artery embolisation
Hysterectomy - only if women has finished family
What can be used to medically shrink fibroids before surgery
GnRH or Ullipristal Acetate
What is red degeneration
(most common in pregnancy) When a fibroid outgrows its blood supply, or torsion of fibroid and its blood supply - leads to thrombosis of vessels and venous engorgement and inflammation:
Symptoms: Abdominal pain, vomiting, low grade fever
US aids diagnosis
treatment: expectant (bed rest and analgesia) relsolves 4-7 days
What is an ovarian cyst
A fluid filled sac on or in the ovary
What are the two broad groups of ovarian cysts
Functional Cysts or Neoplastic Cysts
What are the types of Functional cysts
Caused by disruption to normal cyclic activity
there are follicular cysts or luteal cysts (Associated with PCOS
What are the types of Neoplastic cysts
Mature cystic Teratomas
Endometriomas
Malignant ovarian tumours
What are the symptoms of Ovarian cysts
Most are asymptomatic
But if they are they cause: dull, aching pain, dyspareunia and feeling of pressure, (pain may be cyclical if . endometrioma)
What are the 3 complications of ovarian cysts
Haemorrhage/Bleeding
Torsion
Rupture
What symptoms do you get with ovarian cyst complications
3s’s: Severe, Sudden, Sharp pain
In Torsion: pain, vomiting and low grade fever
In Rupture: Signs of shock: high HR, low BP and haemoperitonium (causes shoulder pain)
What investigations would you do for someone with ovarian cysts
TVS or AUS if indefinite do a MRI
Screen for CA125
Gold standard for type of cyst is US guided biopsy/aspiration or histological analysis on removal
What is the treatment of cysts in pre-menopausal women
Try and preserve womens fertility wherever possible
If cyst under <5cm, non malignant or asymptomatic- Observe and don’t surgically treat
If cyst over 5cm, malignant or symptomatic perform laparoscopic ovarian cystectomy or oopherectomy
What is the treatment of cysts in post-menopausal women
Calcualate risk of malignancy index - CA125, menopause status and US findings
Low risk, under <5cm can be managed with observation and CA125
High risk of malignancy, >5cm or causing complications - bilateral laproscopic oopherectomy and staging
What is the treatment of ruptured cysts
Uncomplicated Rupture (clinically stable): expectant management and NSAIDS Complicated Rupture: cyst that is haemorraging severely - give IV fluids or blood transfusion (treat symptoms of shock) surgery may be needed to remove cyst or ovary and stop bleeding
What is the treatment of torsion
Laproscopic surgery may be needed since lack of blood flow can damage ovaries
What is an ectopic pregnancy and where is most common?
A fertilised ovum outside the uterine cavity and is most common in the ampulla of the fallopian tube
What are the predisposing factors of Ectopic Pregancy?
Damage to fallopian tubes (PID and prev. surgery) Previous ectopic endometriosis Smoking POP or IUCD IVF or subfertility Tube Ligation

asymptomatic/ very mild symptoms
clinically stable
What is done in expectant/observant management ectopic pregnancy
Watch hCG levels fall. If they fall at an unacceptable rate precede to active intervention
What is the criteria for first line medical management ectopic pregnancy
hCG < 1500 (if hCG <5000 can choose surgical or medical intervention as long as all other criteria is met)
no significant pain
adnexal mass <3.5cm and no fetal heart beat
No intrauterine pregnancy on scan
What is medical management of ectopic pregnancy
One dose Methotrexate (observe on day 4 and 7 if hCG has fallen by <15% give second dose)
REMEMBER: ensure they are on reliable contraception for 3 months after as its teratogenic
Analgesia can help with the pain
What is the criteria for surgical intervention
hCG >5000 (if hCG under <5000 but all criteria met below precede to surgical management not medical)
significant pain
adnexal mass >3.5cm and a fetal heart beat
No intrauterine pregnancy

Salpingectomy if other fallopian tube is healthy
Salpingostomy if other fallopian tube is unhealthy to preserve fertility
What is the definition of endometriosis
Endometrial tissue present outside the uterus hormonally driven by oestrogen
What is the commonest location of endometriosis
Endometrioma (chocolate cyst)
What is the cause of endometriosis
Unknown: But 3 theories:
- Retrograde menstruation causes adhesions, growth and invasion
- Metaplasia of Mesothelial tissue e.g nose and lungs
- Immunity impairment: retrograde endometrial cells fail to be destroyed by immune response
What are the symptoms of endometriosis
Some people may be asymptomatic Cyclical Constant chronic pain from adhesions causing chronic inflammation Dysmennorhoea Deep Dyspareunia ( due to involvement of uterosacral ligaments) Dysuria Dyschezia Sub-fertility
What would you find on examination of endometriosis
May be no findings
Speculum: may reveal cervical and vaginal lesions
Bimanual examination: Fixed Retroverted uterus, Adrenal masses or tenderness and tender nodules over Uterosacral ligaments
What investigations would you carry out for endometriosis
TVS may show endometrioma but little else
MRI is useful for bowel involvement
CA125 may be raised
Gold Standard is Laparoscopy for biopsy
What is the treatment for endometriosis
Medical Management Pain relief: NSAIDs e.g. Mefenamic Acid 1st line: COCP or Mirena (IUS) 2nd Line: Progestogen e.g Norethisterone 3rd line: GnRH analogues with HRT therapy Surgical Intervention: Laproscopy using ablation and excision to destroy endometriosis Hysterectomy last resort

What is the process for women with borderline/mild cervical dyskaryosis
Perform HPV test is +ve send for colposcopy
What is the process for women with moderate/severe cervical dyskaryosis
Send straight for colposcopy
Risk factors for CIN
Type of HPV Early age of intercourse Increased number of sexual partners Not using condoms Increased exposure time to HPV Immunocompromised- HIV, transplant, immunosuppressed Smoking
What is an example of primary prevention of CIN
HPV Vaccination is primary prevention
How is CIN investigated using Colposcopy
- Cervix is examined
2. Transformation zone is painted with acetic acid (5%) neoplastic cells take more up so abnormal areas are highlighted
How is CIN managed
Large Loop Excision of Transformation Zone (LLETZ)
- CIN1 (low grade) - should regress without treatment offer 6 month colposcopy and LLETZ if persistant
- > CIN1 (high grade) - spontaneous regression much less likely - excision with LLETZ recommended if high risk HPV after LLETZ - offer 6 monthly smears

Bimanual Examination: hard and rough cervix
Speculum Examination: irregular mass and bleeding on contact
Colposcopy: high/dense uptake of acetic acid, irregular cervix surface
Investigations of cervical cancer
LLETZ for biopsy is contraindicated as it causes heavy bleeding
FBC, U&Es and LFTs
