Q

what are the two types of dysfunctional uterine bleeding?

A

51
Q

what is the pathophysiology of anovulatory uterine bleeding?

A

as there is NO ovulation, CL does NOT produce progesterone.

Endometrium thickens due to unopposed E2 and then outgrows its blood supply, causing necrosis and subsequent shedding.

52
Q

A 
ovulatory= secretory endometrium
anovulatory= proliferative endometrium
53

Fe deficiency anaemia

Infertility

Endometrial hyperplasia + Ca in DUB anovulatory type

Q

on bimanual examination, you notice that the uterus is FIXED and retroverted. what must you consider?

A

endometriosis or PID

55
Q

what does a positive test for cervical excitation during gynae examination often indicate?

A

blood or infection in the pelvis

56
Q

what is the gold standard test to diagnose exclude endometrial hyperplasia/carcinoma?

A

hysterotomy, dilation and curettage

however, NOT first line ix. (really should be using pipelle)

57
Q

risks of performing endometrial sampling?

A

risk of uterine perforation, infection, gas embolism

58
Q

what is your line of action (in terms of ix) with a 58 year old post menopausal woman who presents with vaginal bleeding?

A

working diagnosis- endometrial cancer

  1. transvaginal u/s and endometrial sampling pipelle
  2. if both normal, watch and wait
  3. if abnormal then proceed to hysterotomy, D and C
59
Q

what is normal endometrial thickness on transvaginal u/s?

A

less than 4mm

60
Q

what is the commonest cause of menorrhagia amongst teenage girls?

A

anovulatory dysfunctional uterine bleeding

61
Q

what is the difference between mefanamic acid and tranexamic acid?

A

mefanamic acid= prostaglandin inhibitor

tranexamic acid= anti-fibronolytic agent (inhibits clot breakdown)

62
Q

what are some treatment/management options for heavy menstrual bleeding?

A

prostaglandin inhibitor, antifibronolytic agents
OCP
Depot provera
Mirena

surgical- endometrial ablation or hysterectomy

63
Q

what are some causes of intermenstrual bleeding in a young woman?

A
  1. E2 falls during the menstrual cycle causing a mini E2 withdrawal bleed
  2. Structural cause: Polyps/endometriosis
64
Q

what might persistent post-coital bleeding indicate?

A

cervical dysplasia or cervicitis

65
Q

What is the most common cause of post-coital bleeding?

A

cervical ectropium

66
Q

what causes cervical ectropium?

A

increase E2 levels during puberty

size of ectropium may be increased by OCP and multiparity

67
Q

what are two things we need to consider before deciding to treat endometriosis?

A

plans for fertility

patient’s symptoms

68
Q

what is the medical management of endometriosis?

A

69
Q

how is an endometrial biopsy taken?

A

through a suction pipelle inserted through the cervix to sample fragments of endometrial tissue

70
Q

what are some characteristic u/s results that might indicate ovarian torsion?

A

U/s doppler- reduction of blood flow to the ovary; ring of oedema around the ovary

71
Q

what is the most common coagulopathy which can cause abnormal uterine bleeding

A

VWF deficiency

72
Q

what is the mechanism by which hypothyroidism causes abnormal uterine bleeding?

A

low thyroid levels –> increase CORT levels –> induces E2 –> irregular bleeding/growth of endometrium

73

A

Endometrial disorders in the absence of pelvic pathology

74
