Q

Regarding histology, how is endometriosis diagnosed.

A

Positive histology confirms but negative does not exclue. Histology can exclude rare instances of malignancy in cases of ovarian endometrioma and in deeply infiltrating disease.

Q

Is TVS useful in endometriosis?

A

This has limited value in diagnosis but is a useful tool to make and exclude the diagnosis of an ovarian endometrioma.

Q

What is the treatment for endometriosis?

A

Counselling plus analgesia (NSAIDS) and hormonal suppression of ovarian function for 6 months reduces endometriosis-associated pain (oestrogen and progesterone protect against bone mineral density loss)
You can also give progestogens or the COCP to treat endometriosis.

Q

What is the clinical definition of chronic pelvic pain?

A

Intermittent or constant pain in the lower abdomen or pelvis of at least 6 months duration. It does not occur exclusively with menstruation or intercourse and not associated with pregnancy.

23
Q

What is the gold standard investigation for chronic pelvic pain?

A

Diagnostic laparoscopy

24
Q

What imaging techniques are appropriate in the diagnosis of chronic pelvic pain?

A

Transvaginal scanning to screen for assess of adnexal massess.

25
Q

Which imagining techniques are useful in the diagnosis of adenomyosis?

A

TV scan and MRI

26
Q

How do you treat chronic pelvic pain?

A

Trial with COCP or a GnRH agonist for 3-6 months before having a diagnostic laparscopy

27
Q

How does the COCP work?

A

It induces negative feedback resulting in lower levels of FSH, inhibiting follicular development and preventing an increase in estradiol levels. Progestogen negative feedback and the lack of oestrogen positive feedback on LH secretion prevent a mid-cycle LH surge.

28
Q

How many day packs are the cyclical combined HRT therapies provided and how is this split up in terms of hormones.

A

28 day packs- the first 14 days contain oestogen only and the following 14 days contain oestrogen and progesterone.

29
Q

What is the purposeful effect of HRT on the endometrium?

A

Ideally in the first 14 days the endometrium would be proliferative and in the next 14 days it would be secretory.

30
Q

What is decidua?

A

This is a change in the uterine lining (becomes decidualised) due to a pregnancy. This is regardless of whether the embryonal tissue has implanted in the uterine lining or not and therefore this is how the endometrium would appear in a tubal pregnancy for example. This is a normal hormonal effect and it occurs regardless of the implantation site.

31
Q

Post menopausal bleeding in a woman with no other risk factors is most likely due to what?

A

Atrophic endometrium

32
Q

A tumour of the endometrium is most likely what?

A

Adenocarcinoma

33
Q

So, from days 1-14 of the cycle, what stage is the endometrium in?

A

Proliferative phase

34
Q

What is the first line investigation for a pituitary adenoma?

A

ct scan following hyperprolactinaemia

35
Q

In women who have a first degree relative with a venous thrombo-embolism, what blood test should be used to screen them before giving them the COCP?

A

thrombophilia screen

36
Q

What is the common presentation in a woman with asherman’s syndrome?

A

amenorrhoea, hypomenorrhoea

37
Q

What is D&C?

A

Dilatation and curretage- the cervix is dilated with a steel rod increasing in size, the endometrium is then curetted.

38
Q

When is D&C used?

A

For abnormal uterine bleeding, treatment of missed and incomplete miscarriages and for abortion.

39
Q

Which drugs are used for abortion?

A

Misoprostal and Mifepristone

40
Q

What are the features of nausea and vomiting in pregnancy?

A

It seldom persists beyond 14 weeks and is more common in multiparous women.

41
Q

What is hyperemesis gravidarum?

A

This is when nausea and vomiting in early pregnancy are so sever to cause severe dehydration, weight loss or electrolyte disturbance.

42
Q

What may predispose to hyperemesis gravidarum and must be ruled out?

A

Urinary infection, multiple or molar pregnancy must all be excluded.

43
Q

How is hyperemesis gravidarum treated?

A

IV rehydration, and anti-emetics such as metoclopramide, cyclizine and even ondansetron and thiamine (to prevent neuro complications of vitamin depletion such as Wernicke’s encephalopathy).

44
Q

What is a hydratiform mole?

A

trophoblastic tissue, which is part of the blastocyst invades the endometrium and proliferates in a more aggressive way than normal.

45
Q

What are the two types of hydratiform mole?

A

Complete and partial

46
Q

What is a complete mole?

A

This is entirely paternal in origin, usually when one sperm fertilises an empty oocyte and undergoes mitosis- the result is a diploid tissue usually 46XX.

47
Q

What is a partial mole?

A

This is usually triploid, derived from two sperms and one oocyte- there is variable evidence of a fetus. 69 XXY/ 92XXXY

48
Q

If invasion of the mole is only within the uterus, what is it referred to as?

A

Invasive mole

49
Q

If the mole is invasive with metastasis, what is it called?

A

Choriocarcinoma

50
Q

If there is a persistence of elevation of hCG, what is the condition referred to as?

A

Gestational trophoblastic neoplasia (GTN)

51
Q

Who is gestational trophoblastic disease most common in? ( this inclludes hydratiform mole, invasive mole, choriocarcinoma and the very rare placental site trophoblastic tumour)

A

Women of extremes of gestational age and it is twice as common in Asians.

52
Q

What are the clinical features of gestational trophoblastic disease?

A

Large uterus, early pre-eclampsia and hyperthyroidism. Vaginal bleeding is usual and there may be severe vomiting (hyperemesis).

53
Q

What is seen on ultrasound in GTD?

A

‘snowstorm’ appearance of the swollen villi with complete moles. (grapes)

54
Q

How is diagnosis of GTD confirmed?

A

Histologically.

55
Q

How is GTD managed?

A

Suction curettage (ERPC), followed by serial hCGs. A continued rise is suggestive of malignancy.
