Q

What are fibroids?

A

Fibroids AKA uterine leiomyomas = benign tumours of smooth muscle of the uterus
* Affect 40-60% women in later reproductive years - more common in black women
* Fibroids = oestrogen sensitive (they grow in response to oestorgen)

Q

Types of fibroids

What are the 4 types?

A
  • Intramural = within the myometrium - as they grow they change the shape + distort the uterus
  • Subserosal = Just below the outer layer of the uterus - grow large outwards + filling the abdominal cavity
  • Submuscosal = just below the endometrium
  • Pedunculated = on a stalk

Q

How do fibroids present?

A

Symptoms:
* Heavy periods (menorrhagia): particularly submucosal and intramural
* Prolonged menstruation (more than 7 days)
* Pelvic pain (dysmenorrhoea): particularly submucosal + intramural
* Pain during or after sex (dyspareunia)
* Bleeding between peroids (intermenstrual bleeding)
* Due to pelvic pressure or fullness: Urinary frequency or retention + Bloating or constipation

Signs:
* Pelvic examination: firm, enlarged, and irregularly shaped non-tender uterus = characteristic
* Abdominal examination: a central irregular mass may be found in cases of large fibroids
* Reduced fertility

Q

Ix for uterine fibroids

A

A combination of a history + abdominal + bimanual examination = usually significantly aid diagnosis.
* Hysteroscopy for submucosal fibroids → presenting with heavy menstrual bleeding
* Ultrasound (transabdominal + transvaginal) - transvaginal = diagnostic
* FBC (anaemia or polycythaemia) - fibroids can also secrete erythropoietin which may cause polycythaemia

Q

What is the medical + surgical management for uterine fibroids less than 3cm?

A

Medical management (same as heavy menstrual bleeding):
* First line: Mirena coil (must be no distrortoin of uetrus)
* Symptomatic management (NSAIDs + tranexamic acid)
* COCP
* Cyclical oral progestogens

Surgical:
* Endometrial abalation

Q

Why can endometrial curettage cause Asherman’s syndrome?

A
  • Endometrial curettage (scraping) = can damage the basal layer of the endometrium.
  • This damaged tissue may heal abnormally, creating scar tissue (adhesions) connecting areas of the uterus that are generally not connected.
  • There may be adhesions binding the uterine walls together, or within the endocervix, sealing it shut.
  • These adhesions = form physical obstructionsdistort the pelvic organs → resulting in** menstruation abnormalities, infertility, recurrant miscarriages**

Q

What is the main theory that underpins endometriosis?

A

Retrograde menstruation

The endometrial tissue flows backwards through the fallopian tubes and out into the pelvis + peritoneal cavity during menstruation.

The endometrial tissue then seeds itself around the pelvis + peritoneal cavity

Q

What are the other theories behind endometriosis?

A
  • Embryonic cells destined to become endometrial tissue may remain in areas outside the uterus during the development of the fetus, and later develop into ectopic endometrial tissue.
  • There may be spread of endometrial cells through the lymphatic system, in a similar way to the spread of cancer.
  • Cells outside the uterus somehow change, in a process called metaplasia, from typical cells of that organ into endometrial cells.

Q

Why does cyclical abdominal or pelvic pain occur during menstruation in endometriosis?

A
  • Cells of endometrial tissue outside the uterus = respond to hormones (same way as endometrial lining)
  • During menstruation, as the endometrial tissue in the uterus sheds its lining and bleeds, the same thing happens in the endometrial tissue elsewhere in the body.
  • This causes irritation + inflammation of the tissues around the site of endometriosis
  • → results in cyclical, dull, heavy or burning pain

Q

Why can adhesions occur in endometriosis?

A

Q

Hormonal blood tests that indicate PCOS

A
  • Raised luteinising hormone (LH)
  • Raised LH:FSH
  • Raised testosterone
  • Raised insulin
  • Normal or raised oestrogen levels
64
Q

Ix for PCOS

A

Gold standard: transvaginal ultrasound (‘string of pearls’)

Hormonal blood tests:
* ↑ LH
* ↑ LH:FSH
* ↑ Testosterone
* ↓FSH
* ↓ SHBG

SHBG = sex hormone-binding globulin

Transabdominal USS = alternative

65
Q

What is the diagnostic criteria of the transvaginal or pelvic USS - to diagnose PCOS

A

The follicles may be arranged around the periphery of the ovary → giving a “string of pearls” appearance.

The diagnostic criteria are either:

  • 12 or more developing follicles in one ovary
  • Ovarian volume > 10cm3
66
Q

Is a pelvic ultrasound reliable in adolescents in diagnosing PCOS?

A

No!
Transvaginal = gold standard

67
Q

What screening test may be useful for someone diagnosed with PCOS?

A

Oral glucose tolerance test (OGTT)

68
Q

Why is insulin resistance an important part of PCOS?

A

When someone is resistant to insuiln:
* Pancreas produces more insulininsulin = promotes the release of androgens from the ovaries + adrenal glands
* Therefore → ↑insulin = ↑androgens (e.g. testosterone)

  • Insulin = also suppresses SHBG production from liver
  • SHBG = normally binds to androgens → suppressing their function
  • ↓ SHBG = promotes hyperandrogenism in PCOS
  • ↑ Insulin levels = suppresses follicle development in ovaries → leading to anovulation + multiple partially developed follicles (seen as polycystic ovaries on scan)
69
Q

Mx for PCOS

A

First line: Lifestyle modifications
* Weight loss can restore ovulation + improve insulin resistance + symptoms

Second line:
* Metformin (can help regulate cycles + improve fertilty)
* Oral contraceptive pills (COCP): regulate menstrual cycles, reduce symptoms of hyperandrogenism like acne and hirsutism, and reduce the risk of endometrial cancer
* Clomiphene: used to induce ovulation in women with PCOS who are trying to conceive
* Ovarian drilling: laparoscopic surgical procedure creates multiple holes in the ovaries by diathermy, inducing ovulation and improving fertility

70
Q

What is the triad for PCOS (Rotterdam criteria)?

A
  • Anovulation
  • Hyperandrogenism
  • Polycystic ovaries on USS
71
Q

Functional ovarian cysts related t the fluctuating hormones of the menstrual cycle are very common in which women?

A

Premenopausal women

72
Q

What is the difference in concern between ovarian cysts in premenopausal and postmenopausal women?

A

The majority of ovarian cysts in:
* Premenopausal women → benign
* Postmenopausal women → malignancy risk → further investigation

73
Q

Why can’t a patient with just multiple ovarian cysts or a ‘string of pearls appearance cannot be diagnosed with PCOS?

A

PCOS diagnosis requires at least 2:
* Anovulation
* Hyperandrogenism
* Polycystic ovaries on ultrasound

74
Q

How do ovarian cysts present?

A
  • Mostly asymptomatic

Vague symptoms of:
* Pelvic pain
* Bloating
* Fullness in the abdomen
* A palpable pelvic mass (particularly with very large cysts such as mucinous cystadenomas)

75
Q

When can ovarian cysts present with acute pelvic pain?

A
  • Ovarian torson
  • Haemorrhage
  • Rupture of cyst
76
Q

What are the 2 functional cysts?

A
  • Follicular cysts
  • Corpus luteum cysts
77
Q

What is a follicular cyst?

A

Follicular cyst = functional cyst
Follicular cysts = represent the developing follicle
* Follicle fails to rupture + release the egg → cyst persists

  • Harmless, tend to disappear after a few menstrual cycles
  • Thin walls + no internal structures

Follicular cysts = most common ovarian cyst

78
Q

What are corpus luteum cysts?

A

Corpus luteum cysts = Functional cyst
* Occur when the corpus lutem = fails to break down → then fills with fluid
* Cause pelvic discomfort, pain + delayed menstruation
* Often seen in early pregnancy

79
Q

Name some other ovarian cysts that aren’t functional

A
  • Serous cystadenoma = benign tumours of epithelial cells
  • Mucinous cystadenoma = benign tumours of epithelial cells → HUGE - take up lots of space in the pelvis and admoen
  • Endometrioma = lumps of endometrial tissue within the ovary - occurs in patients with endometriosis, can cause pain + disrupt ovulation
  • Dermoid cysts / Germ Cell Tumours = benign ovarian tumours - = ** ** (come from germ cells), contain various tissue types (e.g. skin, teeth, hair, bone) → associated with ovarian torsion
  • Sex Cord-Stromal Tumours = benign or malignant - They arise from the stroma (connective tissue) or sex cords (embryonic structures associated with the follicles). There are several types, including Sertoli–Leydig cell tumours and granulosa cell tumours.
80
Q

What are the signs and symptoms that suggest an ovarian cyst is malignant?
(From history and examination)

A

Signs:
* Weight loss
* Ascites
* Lymphadenopathy
* Abdominal bloating

Symptoms:
* Reduced appetite
* Early satiety
* Pain

81
Q

Risk factors for ovarian malignancy

A
  • Age
  • Postmenopause
  • Increased number of ovulations
  • Obesity
  • HRT
  • Smoking
  • Breastfeeding (protective)
  • Familt history of BRCA1 + BRCA2 genes

The number of times a woman has ovulated during her life correlates with her risk of ovarian cancer. More ovulations increases the risk of ovarian cancer - like breast cancer

82
Q

What factros will reduce the number of ovulations
(Protective in breast and ovarian cancer)

A
  • Later onset of periods (menarche)
  • Early menopause
  • Any pregnancies
  • COCP use
83
Q

A premenopausal women is found to have a simple ovarian cyst less than 5cm. Does she need further investigations?

A

No!

84
Q

What is the tumour marker for epithelial cell ovarian cancer?

A

CA125

It contributes to the overall impression of whether an ovarian cyst is related to cancer and forms part of the risk of malignancy index

145
Q

Define premature menopause

A

Premature menopause = menopause before the age of 40 years

Premature menopause = result of premature ovarian insufficiency

146
Q

What is menopaused caused by?

A

Menopause = caused by a lack of ovarian follicular function → resulting in changes in sex hormones associated with the menstrual cycle:

  • Oestrogen + progesterone = low
  • LH + FSH = high (in response to an absence of negative feedback from oestrogen)
147
Q

Physiology of menopause

A
  • Inside the ovaries, the process of primordial follicles maturing into primary + secondary follicles = always occurring, independent of the menstrual cycle

At the start of the menstrual cycle:
* FSH = stimulates further development of the secondary follicles.
* As the follicles grow, the granulosa cells that surround them secrete increasing amounts of oestrogen.
* The process of the menopause = begins with a decline in the development of the ovarian follicles.
* Without the growth of follicles → reduced production of oestrogen.
* Oestrogen = has a negative feedback effect on the pituitary glandsuppressing the quantity of LH + FSH produced

As the level of oestrogen falls in the perimenopausal period → there is an absence of negative feedback on the pituitary gland → increasing levels of LH + FSH

The failing follicular development means ovulation does not occur (= anovulation) → resulting in irregular menstrual cycles
* Without oestrogen → endometrium does not develop → leading to a lack of menstruation (amenorrhoea).
* Lower levels of oestrogen = also cause the perimenopausal symptoms.

148
Q

Name some perimenopausal symptoms

A

A lack of oestrogen in the perimenopausal period leads to symptoms of:

  • Hot flushes
  • Emotional lability or low mood
  • Premenstrual syndrome
  • Irregular periods
  • Joint pains
  • Heavier or lighter periods
  • Vaginal dryness and atrophy
  • Reduced libido
149

  • Urinary incontinence
150
Q

Diagnosis (possible Ix) for menopause

A
  • Over 45: Perimenopause + menopause diagnosis can be made without Ix

* Women under 40 years with suspected premature menopause
* Women aged 40 – 45 years with menopausal symptoms or a change in the menstrual cycle

151
Q
A
152
Q

Management of perimenopausal symptoms

A

Vasomotor symptoms = likely to resolve after 2 – 5 years without any treatment. Management of symptoms depends on the severity, personal circumstances and response to treatment. Options include:

  • No treatment
  • Hormone replacement therapy (HRT)
  • Tibolone = a synthetic steroid hormone that acts as continuous combined HRT (only after 12 months of amenorrhoea)
  • Clonidine = which act as agonists of alpha-adrenergic and imidazoline receptors
  • Cognitive behavioural therapy (CBT)
  • SSRI antidepressants (fluoxetine or citalopram)
  • Testosterone - can be used to treat reduced libido (usually as a gel or cream)
  • Vaginal oestrogen cream or tablets, to help with vaginal dryness + atrophy (can be used alongside systemic HRT)
  • Vaginal moisturisers (Sylk, Replens and YES)
153
Q

Fertility gradually declines after 40 years of age. However, women should still consider themselves fertile. Pregnancy after 40 is associated with increased risks and complications. Women need to use effective contraception for….

A
  • Two years after the last menstrual period in women under 50
  • One year after the last menstrual period in women over 50
154
Q

Can hormonal contraceptives affect the menopause, in terms of when it occurs and how long it lasts?

A

No!
But it can suppress + mask symptoms - which can make diagnosing menopause in women on hormonal contraception more difficult

155
Q

Name some good contraception options (UKMEC 1, meaning no restrictions) for women approaching the menopause

A
  • Barrier methods
  • Mirena or copper coil
  • Progesterone only pill
  • Progesterone implant
  • Progesterone depot injection (under 45 years)
  • Sterilisation
156
Q

At what age can the COCP be used up to?

A

50 years old

The combined oral contraceptive pill is UKMEC 2 (the advantages generally outweigh the risks) after aged 40, and can be used up to age 50 years if there are no other contraindications. Consider combined oral contraceptive pills containing norethisterone or levonorgestrel in women over 40, due to the relatively lower risk of venous thromboembolism compared with other options.

157
Q

What are the 2 key side effects of the progesterone depot injection (e.g. Depo-Proverva)?

A
  • Weight gain
  • Reduced bone mineral density (osteoporosis)

These side effects are unique to the depot and do not occur with other forms of contraception. Reduced bone mineral density makes the depot unsuitable for women over 45 years.
