Q

How should bleeding in early pregnancy be managed?

A

> 6 weeks gestation (or of uncertain gestation) + bleeding = referral to early pregnancy assessment service, transvaginal USS to identify the location of the pregnancy and whether there is a fetal pole and heartbeat

< 6 weeks gestation + bleeding, but NO pain or risk factors for ectopic pregnancy, then they can be managed expectantly.

These women should be advised:
to return if bleeding continues or pain develops
to repeat a urine pregnancy test after 7–10 days and to return if it is positive
a negative pregnancy test means that the pregnancy has miscarried

Who gets screened for cervical cancer? How are the samples tested?
A smear test is offered to all women between the ages of 25-64 years 25-49 years: 3-yearly screening 50-64 years: 5-yearly screening HPV first system, i.e. a sample is tested for high-risk strains of human papillomavirus (hrHPV) first and cytological examination is only performed if this is positive
28
What are the 'special situations' in cervical cancer screening?
cervical screening in pregnancy is usually delayed until 3 months post-partum unless missed screening or previous abnormal smears women who have never been sexually active have a very low risk of developing cervical cancer therefore they may wish to opt out of screening women with HIV or significant immuncompromise should have annual smears
29
What is the test of cure (TOC) pathway for cervical cancer screening?
individuals who have been treated for CIN1, CIN2, or CIN3 should be invited 6 months after treatment for a test of cure repeat cervical sample in the community
30
hrHPV +ve and cytologically abnormal =
patient referred for colposcopy
31
hrHPV +ve but cytologically normal =
the test is repeated at 12 months if the repeat test is now hrHPV -ve → return to normal recall if the repeat test is still hrHPV +ve and cytology still normal → further repeat test 12 months later: If hrHPV -ve at 24 months → return to normal recall if hrHPV +ve at 24 months → colposcopy
32
What should be done if the smear sample for cervical cancer screening is inadequate
repeat the sample within 3 months if two consecutive inadequate samples then → colposcopy
33
What is the most common treatment for cervical intraepithelial neoplasia?
Large loop excision of transformation zone (LLETZ)
34
What is a cervical ectropion?
In a cervical ectropion, elevated oestrogen levels (ovulatory phase, pregnancy, COCP use) result in larger area of columnar epithelium (that lines the cervical canal) being present on the ectocervix. Can be asymptomatic or present with vaginal discharge / post-coital bleeding.
35
What tx can be used if a cervical ectropion causes troublesome sxs?
Ablative treatment (for example 'cold coagulation')

45
What is the investigation of choice for ectopic pregnancy?
transvaginal USS
46
How should ectopic pregnancies be managed?
<35mm, unruptured = Expectant management - closely monitoring the patient over 48 hours and if B-hCG levels rise again or symptoms manifest intervention is performed <35mm, ruptured = Medical management - methotrexate >35mm = Surgical management - salpingectomy first line or salpingotomy for women with other risk factors for infertility e.g. contralateral tube damage
47
In which anatomical location are ectopic pregnancies at higher risk of rupture?
the isthmus

postmenopausal bleeding usually light and intermittent initially before becoming heavier premenopausal women may develop menorrhagia or intermenstrual bleeding pain is not common and typically signifies extensive disease vaginal discharge is unusual
52
What are the investigations for suspected endometrial cancer?
All women >= 55 years who present with postmenopausal bleeding should be referred using suspected cancer pathway trans-vaginal USS - a normal endometrial thickness (< 4 mm) has a high negative predictive value hysteroscopy with endometrial biopsy
53
How is endometrial cancer managed?
mainstay is surgery localised disease is treated with total abdominal hysterectomy with bilateral salpingo-oophorectomy patients with high-risk disease may have postop radiotherapy
54
What is endometrial hyperplasia?
abnormal proliferation of the endometrium in excess of the normal proliferation that occurs during the menstrual cycle may present w intermenstrual bleeding
55
How should endometrial hyperplasia be managed?
without atypia: high dose progestogens with repeat sampling in 3-4 months, can use IUS with atypia: hysterectomy is usually advised
56

reduced organ mobility, tender nodularity in the posterior vaginal fornix and visible vaginal endometriotic lesions may be seen on laprascopy
60
How should endometriosis be investigated and managed?
laparoscopy is the gold-standard investigation Mx: NSAIDs / paracetamol for symptomatic relief COCP or progestogens e.g. medroxyprogesterone acetate can be added Secondary treatments: GnRH analogues - induce a 'pseudomenopause' surgery
61

62
Uterine fibroids are sensitive to oestrogen and can therefore grow during pregnancy. If they grow faster than their blood supply this can cause fibroid degeneration. How does this present?

67
Menorrhagia was previously defined as total blood loss > 80 ml per menses, but it was difficult to quantify, so the mx has therefore shifted towards what the woman considers to be excessive How should menorrhagia be investigated and managed?
Ix: FBC, transvaginal USS if symptoms suggest structural abnormality Mx: Does not require contraception = - mefenamic acid 500 mg tds (particularly if there is dysmenorrhoea as well) or tranexamic acid 1 g tds. Both are started on the first day of the period Requires contraception = - IUS (Mirena) should be considered first-line - COCP - long-acting progestogens
68
Hormone replacement therapy (HRT) involves the use of a small dose of oestrogen (combined with a progestogen in women with a uterus) to help alleviate menopausal symptoms. What are the potential side effects?
nausea breast tenderness fluid retention and weight gain
69
What are the risks of HRT?
increased risk of breast cancer increased risk of ovarian cancer increased risk of endometrial cancer (oestrogen by itself should not be given as HRT to women with a womb, reduced by the addition of a progestogen but not eliminated completely) increased risk of VTE (unless transdermal) increased risk of stroke increased risk of IHD if taken more than 10 years after menopause
70
What is Hyperemesis gravidarum? What are the risk factors?

74
Women with hyperemesis gravidarum may develop dehydration, weight loss and electrolyte imbalances. Other complications include:
AKI Wernicke's encephalopathy oesophagitis, Mallory-Weiss tear venous thromboembolism
75

84
Give some risk factors for ovarian cancer
family history: mutations of the BRCA1/ BRCA2 gene many ovulations: early menarche, late menopause, nulliparity
85

abdominal distension and bloating abdominal and pelvic pain early satiety urinary symptoms e.g. Urgency diarrhoea CA125 and USS
86
Which ovarian cysts should be biopsied to exclude malignancy?
complex - multi loculated
87
Give the two types of functional ovarian cysts
Follicular cysts (commonest ) due to non-rupture of the dominant follicle or failure of atresia in a non-dominant follicle commonly regress after several menstrual cycles Corpus luteum cyst more likely to present with intraperitoneal bleeding than follicular cysts
88
Give an example of a benign germ cell tumour that can form on the ovary
Dermoid cyst (mature cystic teratoma) lined with epithelial tissue and hence may contain skin appendages, hair and teeth usually asymptomatic torsion is more likely than with other ovarian tumours
89
Give an example of benign epithelial tumours that can form on the ovary
Serous cystadenoma the most common benign epithelial tumour which bears a resemblance to the most common type of ovarian cancer (serous carcinoma) Mucinous cystadenoma they are typically large and may become massive if ruptures may cause pseudomyxoma peritonei
90
How should ovarian cysts be managed?
Premenopausal women a conservative approach can be taken for younger women (esp < 35 years) as malignancy is less common. If the cyst is small (e.g. < 5 cm) and 'simple' then it is likely to be benign. A repeat USS should be arranged for 8-12 weeks Postmenopausal women physiological cysts are unlikely any postmenopausal woman with an ovarian cyst should be referred to gynaecology for assessment
91
What is Ovarian hyperstimulation syndrome (OHSS)?
a complication seen in some forms of infertility treatment Mild Abdominal pain and bloating Moderate• Nausea and vomiting Ultrasound evidence of ascites • Severe Clinical evidence of ascites Oliguria Critical Anuria Tense ascites Thromboembolism ARDS
92
What is ovarian torsion? How does it present?
partial or complete torsion of the ovary on it's supporting ligaments that may compromise the blood supply If the fallopian tube is also involved then it is referred to as adnexal torsion sudden onset deep-seated colicky abdominal pain Associated with vomiting and distress fever may be seen in a minority (possibly secondary to adnexal necrosis) Vaginal examination may reveal adnexial tenderness
93
What are the risk factors for ovarian torsion?
ovarian mass: present in 90% of cases being of a reproductive age pregnancy ovarian hyperstimulation syndrome
94
What may you see on USS for ovarian torsion? How would you investigate and manage further?
free fluid or a whirlpool sign Laparoscopy is usually both diagnostic and therapeutic - surgical detorsion
