Q

Investigating chronic pelvic pain?

A

Daily pain diary for 2-3 menstrual cycles to help identify any provoking factors or temporal associations

Q

How common is dyspareunia?

A

1 in 13 women in the UK - 7.5%

24
Q

What is the broad ligament?
What is it made up of?

A

A flat sheet of peritoneum associated with the uterus and ovaries
Made up of mesometrium, mesovarium and mesosalpinx

25
Q

What is the ovarian ligament connected to?

A

Connects the ovary to the side of the uterus
It lies within the broad ligament

26
Q

What is the function of the suspensory ligament of the ovary?

A

It extendards outwards from the ovary to the lateral abdo and wall
Contains the ovarian vessels and nerves

27
Q

Function of the round ligament?

A

Originates at the uterine horns and attaches to the labia majora, passing through the inguinal canal
Supports and anchors the uterus

(This often causes pelvic pain during pregnancy)

28
Q

Ligaments of the pelvis?

A

Iliolumbar ligament
Sacrospinous ligament
Sacrotuberous ligament

29
Q

What is pelvic venous congestion syndrome?

A

When varicose veins develop around the ovaries
Causes chronic pelvic pain unrelated to menstruation or pregnancy

30
Q

What is vaginismus?

A

The body’s automatic reaction to the fear of vaginal penetration
Involuntary muscle spasms in the vagina when something enters it

31
Q

Possible treatments for vaginismus?

A

Psychosexual therapy
Relaxation techniques
Pelvic floor exercises
Sensation focus
Vaginal trainers

32
Q

What can cause vaginismus?

A

fearing that your vagina is too small
a bad first sexual experience
an unpleasant medical examination
believing sex is shameful or wrong
a painful medical condition, like thrush

33
Q

Features of sexual abuse in a child?

A

pregnancy
sexually transmitted infections, recurrent UTIs
sexually precocious behaviour
anal fissure, bruising
reflex anal dilatation
enuresis and encopresis
behavioural problems, self-harm
recurrent symptoms e.g. headaches, abdominal pain

34
Q

What is lichen simplex?
Whats its characterised by?
What causes it?

A

A chronic itchy skin disorder
Characterised by well demarcated, erythematous patches and plaques of thick, leathery skin

Q

What is lichen sclerosus?
Where does it usually affect?
Who normally gets it?

A

An inflammatory condition that usually affects the genitalia
More common in elderly females

36
Q

How does lichen sclerosus present?

A

White patches that may scar
Prominent itch
May result in dyspareunia or dysuria

37
Q

Management and follow up of lichen sclerosus?

A

Topical steroids and emollients

Follow up due to increased risk of vulval cancer. If there is clinical suspicion of VIN or cancer then biopsy

38
Q

What is lichen planus?
How does it present?

A

A skin disorder of unknown aetiology, likely immune-mediated

Itchy, papular rash common on palms, soles, genitalia and flexor surfaces of arms.
Rash is often polygonal in shape with white-lines on the surface (wickhams striae)
Koebner phenomenon may be seen
Oral involvement in 50% - white-lace pattern on buccal mucosa
Thinning of nail plate and longitudinal ridging

39
Q

Management of lichen planus?

A

Potent topical steroids
Benzydamine mouthwash or spray for oral lichen planus

40
Q

What is Bartholin’s cyst?

A

When the ducts become blocked and the Bartholin’s glands expand to form a cyst
Sometimes linked to STIs or other bacterial infections

41
Q

Who do Bartholin’s cyst most typically affect?

A

Sexually active women aged 20-30

42
Q

Why are Bartholin’s cyst unlikely in children and after menopause?

A

Bartholin’s glands dont usually start functioning until puberty
They also commonly shrink after menopause

43
Q

Types of benign ovarian cysts?

A

Physiological cysts
Benign germ cell tumours
Benign epithelial tumours
Benign sex cord stromal tumours

44
Q

What should you do with any complex ovarian cyst?

A

Biopsy to exclude malignancy

45
Q

Name of benign germ cell tumour?

A

Dermoid cyst - aka mature cystic teratomas!

46
Q

What is the most common benign ovarian tumour in a woman under the age of 30?

A

Dermoid cysts (mature cystic teratoma)

47
Q

most common benign epithelial ovarian tumours?

A

Serous cystadenoma
Mutinous cystadenoma

Less common - brenner tumour

48
Q

2 types of physiological ovarian cysts?

A

Follicular cyst
Corpus luteum cyst

49
Q

benign sex cord stromal oavrian tumour

A

Fibroma - most common
Sertoli-leydig tumour

50
Q

What is the most common type of ovarian cyst?

A

Follicular cysts

51
Q

What causes follicular cysts?
Prognosis?

A

Non-rupture of the dominant follicule, or failure of atresia in a non-dominant follicle

Commonly regress after several menstrual cycles

52
Q

What is a corpus luteum cyst?
Is it more or less likely to present with intraperitoneal bleeding than follicular cysts?

A

If the corpus luteum doesnt break down as usual then it can fill with blood or fluid and form a cyst
More likely!

Q

What is an endometrioma?

A

Aka a chocolate cyst
Present in those with endometriosis
There is bleeding into the cyst resulting in that appearance

Q

Outline features of the ovarian cysts in PCOS?

A

When the ovaries contain more than 12 antral follicles or an ovarian volume greater than 10ml
Classic ‘ring of pearls’ sign if seen on USS

55
Q

What are theca lutein cysts?
