Q

Corpus luteum

A

What the follicle turns into after ovulation
Produces oestrodiol and progesterone
Lasts for 2 weeks producing hormones unless egg is fertilised (stays for about 3 months until placenta takes over)
Degenerates into corpus albicans (doesn’t produce hormones)

Q

Cervicitis

A

the cervix appears red, congested and sometimes oedematous. There may be purulent discharge and the cervix is usually tender to palpation. The most common cause of infection currently is Chlamydia trachomatis. Neisseria gonorrhoeae as a cause of cervicitis should not be forgotten. A rarer cause is Trichomonas vaginalis where the cervix is friable, with prominent papillae and punctate haemorrhages, and is commonly described as a ‘strawberry cervix’. Herpetic cervicitis gives rise to multiple ulcerated regions

55
Q

Causes of menorrhagia

A

Uterine and ovarian pathologies, such as uterine fibroids, endometriosis, and pelvic inflammatory disease.
Systemic diseases and disorders, such as coagulation disorders, hypothyroidism, diabetes mellitus, and liver or kidney disease.

Less than 3cm with suspected / diagnoses adenomyosis

59
Q

Adenomyosis

A

when the tissue that normally lines the uterus (endometrial tissue) grows into the muscular wall of the uterus. The displaced tissue continues to act normally — thickening, breaking down and bleeding — during each menstrual cycle

60
Q

Adenomyosis treatment

A

Hysterectomy

61
Q

Causes of heavy periods

A

conditions affecting your womb, ovaries or hormones, such as polycystic ovary syndrome, fibroids, endometriosis and pelvic inflammatory disease
some medicines and treatments, including some anticoagulant medicines and chemotherapy medicines
stress and depression
Rarely, heavy periods can be a sign of womb cancer.

62
Q

Menorrhagia treatment

A

IUS
COCP
Tranexamic acid
Anti-inflammatory painkillers - mefenamic acid, naproxen

63
Q

Tramexamic acid

A

Helps the blood to clo
Side effects - nausea, diarrhoea, red itchy skin
Generally considered safe for breast feeding mothers
Don’t take whilst pregnant

64
Q

Primary dysmenorrhagia

A

in young females in the absence of any identifiable underlying pelvic pathology. It is thought to be caused by the production of uterine prostaglandins during menstruation, which causes uterine contractions and pain.

65
Q

Secondary dysmorrhagia

A

caused by an underlying pelvic pathology (such as endometriosis, fibroids, or pelvic inflammatory disease [PID]) or by intrauterine device (IUD) insertion

66
Q

Dysmenorrhagia prevalence

A

16-91% of women in reproductive age

67
Q

Primary dysmenorrhea risk factors

A

earlier age at menarche, heavy menstrual flow, nulliparity, and family history of dysmenorrhoea

68
Q

Primary dysmenorrhoea onset

A

6–12 months after the menarche, once cycles are regular.
The pain starts shortly before the onset of menstruation and may last for up to 72 hours, improving as the menses progresses.

69
Q

Features of primary dysmenorrhoea

A

The pain is usually lower abdominal but may radiate to the back and inner thigh. It may be accompanied by non-gynaecological symptoms, such as vomiting, nausea, diarrhoea, fatigue, irritability, dizziness, headache, and lower back pain.
Pelvic examination is normal

70
Q

Onset of secondary dysmenorrhoea

A

often starts after several years of painless periods.
The pain is not consistently related to menstruation alone and may persist after menstruation finishes or may be present throughout the menstrual cycle but is exacerbated by menstruation.

71
Q

Features of secondary dysmenorrhagia

A

Other gynaecological symptoms (such as dyspareunia) are often present.
Pelvic examination may be abnormal, but the absence of abnormal findings does not exclude secondary dysmenorrhoea.

72
Q

Secondary dysmenorrhoea red flags

A

Ascites and/or a pelvic or abdominal mass (where it is clear that this is not due to uterine fibroids).
Abnormal cervix on examination.
Persistent intermenstrual or postcoital bleeding without associated features of PID, such as pelvic pain, deep dyspareunia, and abnormal vaginal or cervical discharge.

73
Q

Treatment of secondary dysmenorrhoea

A

Refer to secondary care - treat underlying cause

74
Q

Treatment of primary dysmenorrhoea

A

A nonsteroidal anti-inflammatory drug (such as ibuprofen) and/or paracetamol will usually provide pain relief.
For women who do not wish to conceive, hormonal contraception is an alternative first-line treatment and has the additional advantage of providing contraception.
Local application of heat (for example, a hot water bottle or heat patch) and transcutaneous electrical nerve stimulation (TENS) may also help to reduce pain.
If symptoms are severe and have not responded to initial treatment within 3–6 months or if there is doubt about the diagnosis, referral to a gynaecologist should be arranged.

75
Q

Primary amenorrhoea

A

No menses by age 14 in the absence of secondary sexual characteristics
No menses by 16 with secondary sexual characteristics

76
Q

Secondary amenorrhoea

A

Menstruation has previously occurred but has stopped (at least 6 months, longer when menses previously infrequent)

77
Q

Cause of primary amenorrhoea

Secondary sexual characteristics are present

A 
Constitutional delay
Genitourinary malformation
Testicular feminisation
Hyperprolactinaemia
Pregnancy
78
Q

Constitutional delay

A

there is no abnormality but she is a little later than her peers in reaching her menarche. Ask about the age of menarche in her mother and any older sisters. Reassure that the menarche is the last of the characteristics to develop

79
Q

Genitourinary malformation

A

E.g. imperforate hymen, transverse vaginal septum or absence of the uterus or vagina (eg, Müllerian agenesis). Absence of a vagina may have previously gone unnoticed. If a uterus is present but there is no passage to the outside, there may be cyclical lower abdominal pains.

80
Q

Testicular feminisation

A

also called androgen resistance syndrome, this occurs with an XY karyotype. There may be ambiguous genitalia.The external appearance is as a normal adolescent girl but there are no internal female organs. The gonads are testes that produce testosterone. There are no ovaries, Fallopian tubes, uterus or upper vagina. The clinical manifestation is variable according to the degree of androgen sensitivity.

81
Q

Hyperprolactinaemia

A

can be due to many causes, including hypothyroidism and medication, especially phenothiazines. If it is due to a pituitary tumour, the level of prolactin (PRL) is usually very high.

82
Q

Causes of primary amenorrhoea

Secondary sexual characteristics absent

A 
Ovarian failure
Hypothalamic failure
Failure of hypothalamic-pituitary acid
Congenital adrenal hyperplasia (CAH)
Ambiguous genitalia
83
Q

Ovarian failure

A

due to chemotherapy, irradiation, or chromosomal gonadal abnormality (eg, Turner syndrome).

84
Q

Hypothalamic failure

A

this can be due to chronic illness, excessive exercise, stress or being significantly underweight. Anorexia nervosa usually develops after the menarche and represents a regression. Obesity is also more likely to cause secondary amenorrhoea.

85
Q

Failure of hypothalamic-pituitary axis

A

Tumours, irradiation, infection or head injury involving the hypothalamus or pituitary.
Kallmann’s syndrome: characterised by failure of secretion of gonadotropin-releasing hormone (GnRH), tumours of the hypothalamus or pituitary gland along with other causes of hypopituitarism and hydrocephalus.
Other syndromes including empty sella syndrome, Prader-Willi syndrome and Laurence-Moon syndrome.

86
Q

Congenital adrenal hyperplasia (CAH)

A

can cause precocious puberty or at least pseudoprecocious puberty as the development of sexual characteristics is not followed by menstruation

87
Q

Causes of ambiguous genitalia

A

Eg androgen-secreting tumours

5 alpha-reductase deficiency

88
Q

Precocious puberty

A

The appearance of signs of pubertal development at an abnormally early age
Before 8 in girls
Before 9 in boys

89
Q

Most common cause of secondary amenorrhoea

A

Pregnancy (in women of childbearing age)

PCOS, hypothalamic amenorrhoea, hyperprolactinaemia, primary ovarian insufficiency

90
Q

Secondary amenorrhea causes

No signs of androgen excess

A 
pregnancy, lactation and the menopause
Premature ovarian failure
Depot and implant contraception 
Cervical stenosis and intrauterine adhesions (Asherman’s syndrome)
Hypothalamic dysfunction
Loss of weight
Pituitary disease andhyperprol
Thyroid disease
Iatrogenic
‘Post-pill amenorrhoea’
91
Q

No signs of androgen excess

Pregnancy, lactation and the menopause

A

physiological causes. Secondary amenorrhoea is due to pregnancy until proved otherwise. Even denial of sexual activity should be taken with a degree of circumspection.

92
Q

No signs of androgen excess

Premature ovarian failure

A

physiological causes. Secondary amenorrhoea is due to pregnancy until proved otherwise. Even denial of sexual activity should be taken with a degree of circumspection.

93
Q

No signs of androgen excess

Depot and implant contraception

A

often produces amenorrhoea and the progestogen-only contraceptive pill can do so less often. Intrauterine contraceptive devices usually increase menstrual flow but intrauterine contraceptive systems (Mirena® and to a lesser degree Jaydess®) reduce menstrual flow and may stop it.

94
Q

No signs of androgen excess

Asherman’s syndrome

A

Cervical stenosis and intrauterine adhesions

95
Q

No signs of androgen excess

Hypothalamic dysfunction

A

may cause menstruation to cease. Causes include: stress, excessive exercise, eating disorders, depression, chronic systemic illness and tumours.

96
Q

No signs of androgen excess

Loss of weight

A

especially if rapid. Body mass index (BMI) is rarely above 19 where this is the case, and at least 10% of normal body weight has been lost. Anorexia nervosa and other eating disorders including bulimia nervosa should be considered. The female athlete triad is well recognised. It consists of eating disorder, amenorrhoea and osteoporosis, predisposing to stress fractures. The triad affects not just distance runners but gymnasts and dancers

97
Q

No signs of androgen excess

Pituitary disease and hyperprolactinaemia

A

prolactinomas cause raised prolactin levels and subsequent amenorrhoea. Medication (for example, phenothiazines, methyldopa, cimetidine, opiates and metoclopramide) may raise prolactin levels. Recreational drugs may also cause this; prolonged amenorrhoea is very common in heroin abusers. They are usually underweight but there may also be a pharmacological effect. The pituitary gland may be damaged by tumours, trauma, cranial irradiation, sarcoidosis or tuberculosis. Sheehan’s syndrome is acute pituitary infarction due to postpartum haemorrhage.

98
Q

Sheehan’s syndrome

A

acute pituitary infarction due to postpartum haemorrhage.

99
Q

No signs of androgen excess

Thyroid disease

A

either hypothyroidism or hyperthyroidism may affect menstruation.

100
Q

No signs of androgen excess

Iatrogenic

A

apart from medication discussed above (those which raise prolactin and hormonal medication), other iatrogenic causes include surgery (hysterectomy, endometrial ablation, ovarian surgery), irradiation and chemotherapy.

101
Q

No signs of androgen excess

‘Post-pill amenorrhoea’

A

this occurs when stopping oral contraceptives does not lead to a resumption of a normal menstrual cycle. It usually settles spontaneously in around three months but, if not, it requires investigation. It may be that the cause of amenorrhoea started whilst taking the contraceptives which induced an artificial cycle, masking the issue until they were stopped.

102
Q

Signs of androgen excess

Features

A

Eg hirsuism, acne, virilisation

103
Q

Secondary amenorrhoea causes

Signs of androgen excess

A

Polycystic ovary syndrome (PCOS)
Cushing’s syndrome
Late-onset congenital adrenal hyperplasia
Adrenal or ovarian carcinoma

104
Q

Androgen excess

PCOS

A

PCOS accounts for as many as 30% of cases of amenorrhoea. Both androgens and oestrogens may be normal or slightly raised so that, whilst there are signs of virilisation, there is no evidence of oestrogen deficiency. They are usually, but not always, overweight and may have insulin resistance. Fat is very important in the metabolism of the steroid sex hormones and it accounts for both the excess in PCOS and the deficiency in anorexia.

105
Q

Androgen excess

Cushing’s syndrome

A

may be spontaneous or iatrogenic

106
Q

Androgen excess

Late-onset congenital adrenal hyperplasia

A

Produces androgens

107
Q

Androgen excess

Adrenal or ovarian carcinoma

A

Can produce androgens

108
Q

Key amenorrhoea questions

A 
Duration of amenorrhoea.
Contraception, recent and current.
Vasomotor symptoms.
Galactorrhoea.
Exercise habits.
Stresses.
Medication history.
Past medical history.
109
Q

Amenorrhoea investigations

A

Pregnancy test (if appropriate). Urinary or serum hCG is measured.
Follicle-stimulating hormone (FSH) and luteinising hormone (LH). FSH and LH are raised in ovarian failure; an FSH level ≥20 IU/l in a woman aged under 40 with secondary amenorrhoea indicates ovarian failure.
Prolactin. (Raised in 7.5% of women with amenorrhoea), measure at least twice
Total testosterone and sex hormone-binding globulin
TFTs - Low T4 with low thyroid-stimulating hormone (TSH) suggests pituitary failure.
Pelvic ultrasound

110
Q

Some of the extra potential amenorrhoea investigations

A

Karyotyping may be required to exclude Turner syndrome, testicular feminisation and rarer conditions such as XXX
Where chronic illness is suspected, investigation follows clinical findings.
MRI or CT where pituitary tumour is suspected or for investigation of adrenal or ovarian tumours.
Hysteroscopy may be required for Asherman’s syndrome.

111
Q

When do you need an FSH blood test to diagnose menopause

A

(Must not be taking combined oestrogen and progestogen contraception or high-dose progestogen as reduced accuracy of results)
Women aged over 45 years with atypical symptoms.
Women between 40–45 years with menopausal symptoms, including a change in their menstrual cycle.
Women younger than 40 years in whom premature menopause is suspected.

112
Q

How is menopause clinically diagnosed normally

A

Age + symptoms
