Q

What are the risk factors for HIV infection?

A 
Multiple sexual partners
Migration from high prevalence countries (esp. Sub-Saharan Africa)
Failure to use barrier contraception
Presence of other STIs
IV drug use
Sexual contact with high risk males
Blood product transfusion
18
Q

What does sexual health screening for women involve?

A

Swabs taken from vagina - endocervical for chlamydia and gonorrhoea, posterior fornix for TB & BV, group B strep, and candida.
A fresh urine sample is also requested.
For both men and women, blood tests will be offered for syphilis and HIV.

19
Q

What does sexual health screening for men involve?

A

Fine swabs from urethra for gonorrhea and non-specific urethritis. Fresh urine sample for chlamydia.
Some people may be offered a test for HepB and HepC. Gay and bisexual men will be offered HepB vaccination.

20
Q

What methods of emergency contraception are available?

A

The morning after pill. There are two varieties. Levonell contains a single 1.5mg dose of levonorgestrel and is best taken within 24 hours and no later than 72 hours after intercourse. It affects sperm function, endometrial receptivity and may prevent follicular rupture. Vomiting and menstrual disturbances may occur in following cycle.

Ullipristol (ellaOne) - selective progesterone receptor modulator which prevents ovulation and may affect implantation. It can be used up to 120 hours afterwards. It reduces the effectiveness of progesterone containing contraceptives.

Mirena coil if inserted within 5 days of ovulation.

21
Q

What routine tests should be done before termination of pregnancy?

A

FBC, blood group and rhesus status
If clinically indicated, HIV, HBV, HCV and haemoglobinopathies and cervical smear
Screening for chlamydia

22
Q

What is the preferred method of termination <7 weeks gestation?

A

Medical - using mifepristone plus a prostaglandin e.g. misoprostol is the most effective method of abortion and can also be used for gestations 7-9 weeks.

23
Q

What methods of termination are available at 7-13 weeks gestation?

A

Surgical - suction termination

Medical - mifepristone and prostaglandin

24
Q

What methods of termination are available >15 weeks?

A

Medical TOP is the most usual and effective method at 13-24 weeks. Beyond 21 weeks, feticide via injection of KCI should be considered.
Surgical dilatation and evacuation is also possible >15 weeks with skilled practitioners. Cervical preparation may be beneficial.

25
Q

What re the complications of TOP?

A 
Haemorrhage
Infection
Uterine perforation
Cervical trauma
Failure of TOP
Multiple surgical abortions are associated with an increased risk of subsequent preterm delivery
Psychological sequelae are common
26
Q

What is the differential diagnosis for IMB and irregular menstruation?

A

Anovulatory cycles in early and late reproductive years
Pelvic pathology e.g. fibroids, uterine and cervical polyps, chronic pelvic infection, adenomyosis and ovarian cysts.
In older women, particular if there has been a recent change, malignancy should be considered.

27
Q

What investigations should be done for IMB?

A

Speculum and bimanual, cervical smear
Bloods - Hb, clotting, TFTs
TVUS for endometrial thickness, uterine fibroids, ovarian masses and large intrauterine polyp.

28
Q

When should an endometrial biopsy be taken for IMB?

A

If endometrial thickness >10mm or a polyp is suspected, or if a woman is >40 with recent onset menorrhagia or IMB or has not responded to treatment.

29
Q

What is the differential for PCB?

A

Cervical carcinoma
Ectropion
Cervical polyps
Cervicitis, vaginitis

30
Q

What is the clinical definition of menorrhagia?

A

Excessive menstrual loss that interferes with the woman’s physical, emotional, social and material quality of life. Objectively, it’s a blood loss of >80ml.

31
Q

What are the causes of menorrhagia?

A

The majority of women with menorrhagia have no histological abnormality that can be implicated.
Uterine fibroids
Polyps
Chronic pelvic infection
Ovarian tumours
Endometrial and cervical malignancy
Rare: thyroid disease, haemostatic disorders

32
Q

What treatments are available for menorrhagia?

A

First line medical treatment: Mirena coil - reduces menstrual flow by >90%.

Second line: tranexamic acid (antifibrinolytics) and NSAIDs

Third line: Progestogens and GnRH antagonists

Surgical options include polyp removal, endometrial ablation, myomectomy, hysterectomy and uterine artery embolisation.

33
Q

What is the average age of menopause in the UK?

A

50.5 years

34
Q

What risk factors are there for premature ovarian failure?

A

Autoimmune disease
Down’s syndrome
Turner’s syndrome

35
Q

How is menopause diagnosed biochemically?

A

Age >50 with FSH >30 IU/dl

Age <50 - 2 readings required

36
Q

What are common problems of menopause?

A

Vasomotor symptoms - hot flushes ad night sweats
Cardiovascular disease
Urogenital problems - oestrogen deficency can cause vaginal atrophy, urinary problems (frequency, nocturia, urgency, incontinence)
Sexual problems including loss of libido and dyspareunia
Osteoporosis

37
Q

What is the differential for PMB?

A 
Endometrial carcinoma
Endometrial hyperplasia, atypia and polyps
Cervical carcinoma
Atrophic vaginitis
Cervicitis
ovarian carcinoma
Ovarian polyps
38
Q

How should PMB be investigated?

A

Bimanual and speculum
Cervical smear
Transvaginal US
If endometrium is equal to or greater than 4mm, or if there have been recurrent bleeds, endometrial biopsy and hysteroscopy may be required.

39
Q

What is endometriosis?

A

The presence of endometrium outside the uterine cavity.

40
Q

What are common features of endometriosis?

A

41
Q

How may endometriosis be managed?

A

Conservatively - simple analgesia, support groups

Medical - to cause atrophy of the ectopic endometrium - COCP, progestogens, GnRH agonists combined with add back HRT

Surgical - laparoscopic ablation and excision, TAH and BSO.
