Q

What is the pearl index?

A

The Pearl Index is the most common technique used to describe the efficacy of a method of contraception. The Pearl Index describes the number of pregnancies that would be seen if one hundred women were to use the contraceptive method in question for one year. 0.2 = 2/1000/year.

Q

What is the treatment for a vaginal vault prolapse?

A

The treatment for vaginal vault prolapse is sacrocolpoplexy. This procedure suspends the vaginal apex to the sacral promontory. This support is usually afforded by the uterosacral ligaments.???? But this apparently uses mesh, so most appropriate may be sacrospinous fixation.

Q

Explain how and when a diagnostic hysteroscopy may be completed.

A

How: Diagnostic hysteroscopy is when the uterine cavity is inspected with a rigid or flexible hysteroscope passed through the cervical canal. The uterine cavity is distended using carbon dioxide or saline. Anaesthetic options? Nothing, cervical local anaesthetic block, general anaesthetic.

When: Used as an adjunct to endometrial biopsy or if menstrual problems don’t respond to medical tx.

Q

How is a hysteroscopic surgery completed?

A

An operating hysteroscope is used (small instruments are passed down a parallel channel). Usual procedures involve TransCervical Resection of Endometrium (TCRE) or TransCervical Resection of Fibroids (TCRF) - if the fibroid is intracavity. Also for the removal of intracavity fibroids. Also for resection of the uterine septum. Usually, cutting diathermy and glycine irrigation fluid is used.

Q

Why are the fallopian tubes (bilateral salpingectomy) often removed when a hysterectomy is performed?

A

To reduce the risk of ovarian cancer as ovarian cancer often originates from the fimbral end of the fallopian tube (spreads along the peritoneal surface) and there is no use in having fallopian tubes with no uterus.

Q

How is uterine artery embolisation carried out?

A

(For fibroids). With the patient under conscious sedation and local anaesthesia, a catheter is inserted into the femoral artery (bilateral catheters are sometimes used). Fluoroscopic guidance is used to manipulate the catheter into the uterine artery. Small embolisation particles/sclerosing agents are injected through the catheter into the arteries supplying the fibroids, with the aim of causing thrombosis and consequent fibroid infarction.

43
Q

What are the different surgical options for repair of pelvic organ prolapse?

A

• A pelvic floor repair if you have prolapse of the anterior or posterior walls of the vagina
(cystocele or rectocele); this is where the walls of your vagina are tightened up to support the
pelvic organs. This is usually done through your vagina so you do not need a cut in your abdomen.

• Operations that aim to lift up and attach your uterus or vagina to a bone towards the sacrum or the sacrospinous ligament (sacrocolpopexy or sacrospinous fixation). These
may be done by keyhole surgery.

• A vaginal hysterectomy (removal of the uterus) is sometimes performed for uterine prolapse.
Your gynaecologist might recommend that this be performed at the same time as a pelvic
floor repair.

• Closing off your vagina (colpocleisis) may be considered but only if you are in very poor medical
health or if you have had several operations previously that have been unsuccessful. Vaginal
intercourse is no longer possible after this operation.

44
Q

How is an anterior repair for a cystocele specifically completed?

A

Excision of prolapsed vaginal wall and plication of bladder base and fascia. Vagina wall excision is then closed.

45
Q

How is an posterior repair for a rectocele specifically completed?

A

Levator ani plicated between vaginal wall and rectum.

46
Q

What are the complications of anterior repair and posterior repair operations?

A

Retention of urine, overtightening of the vagina

47
Q

What is the surgical tx for urinary stress incontinence?

A

Burch colposuspension - dissection through an abdominal incision in the extraperitoneal space over bladder and anterior vaginal wall. The vaginal wall on either side of the bladder neck is hitched up to the iliopectineal ligament on either side of the symphysis pubis with non-absorbable sutures.

54
Q

Why do we do urodynamics testing?

A

For diagnosis
To determine if more stress or urgency as this will change management
To investigate problems with voiding

55
Q

How is urodynamic testing carried out?

A

1) Uroflowmetry - measures how much urine is in your bladder and how fast the urine comes out, also known as flow rate. You wee into a special commode.
2) Postvoid residual measurement - measures how much urine is left in your bladder after you urinate. If you have 100–150 milliliters of urine or more left in your bladder, your bladder is not emptying completely. This test can be conducted with an ultrasound NIH external link or by feeding a catheter into your bladder to drain and measure remaining urine.

3) Cystometric test - measures:
- how much urine your bladder can hold
- how much pressure builds up inside your bladder as it stores urine
- how full your bladder is when you start feeling the urge to urinate

First, a catheter is used to empty your bladder completely. Then a special, smaller catheter is placed in the bladder. This catheter has a pressure-measuring device called a manometer. Another catheter may be placed in the rectum or vagina to record pressure there.

Once you completely empty your bladder, it is filled slowly with warm water. You’ll be asked to describe how the bladder feels and when you feel the need to start urinating. When you start feeling that urge, the volume of water and the bladder pressure are recorded.

You may be asked to cough or strain during this procedure to see if the bladder pressure changes or if you leak urine.

A cystometric test can also identify if your bladder contracts when it’s not supposed to.

57
Q

What drugs are contraindicated for Ulipristal Acetate use as emergency contraception?

A

Drugs that induce hepatic enzyme activity (e.g. carbamazepine, eslicarbazepine acetate, nevirapine, oxcarbazepine, phenytoin, phenobarbital, primidone, ritonavir, St John’s wort, topiramate and, above all, rifabutin and rifampicin), and possibly also griseofulvin. Also drugs that reduce hepatic activity such as itraconazole may increase plasma concentrations for longer.

58
Q

Is keppra (levetiracetam) a contra-indication for Ulipristal Acetate?

A

No - it is not an enzyme inducer. There are no contraindications for it’s use.

59
Q

When can Levonelle (Levonorgestrel) be used?

A

It can be used within 72 hours (12-24 hours preferably), 1.5mg dose.

60
Q

How effective is Levonelle (Levonorgestrel)?

A

Levonorgestrel is thought to prevent: up to 95% of pregnancies if taken within 24 hours. up to 85% if taken within 25-48 hours. up to 58% if taken within 49-72 hours.

61
Q

When can Ulipristal Acetate be used as emergency contraception?

A

5 days /120 hrs after coitus. 30mg one dose. Not used if patient is on enzyme inducing drugs or asthmatic + needing glucocorticoids.

62
Q

Why can Ulipristal not be used in asthmatics for emergency contraception?

A

Use in women with severe asthma insufficiently controlled by oral glucocorticoids is not recommended. Ulipristal acetate has a steroid structure and acts as a selective progesterone receptor modulator with predominantly inhibitory effects on the progesterone receptor. Reduces the effect of glucocorticoids? Worsening asthma?

63
Q

What questions must a doctor ask of a young woman coming in for emergency contraception?

A

They must establish the details of what happened. Age of partner? Regular or casual partner? Did you know them? Was alcohol involved? Was drugs involved? Were you forced? Did you use protection? Are you on contraception? Is this the first time this has happened? Has this happened before? Do your parents know?

64
Q

What is the management for a young woman coming in for emergency contraception?

A

1) Emergency contraception
2) Ongoing contraception
3) STI screen +/- Abx
4) Safeguarding/Information

65
Q

How does Levonorgestrel work?

A

1) Inhibits ovulation
2) Thickens cervical mucus - creating a physical barrier between sperm and egg meeting/sperm from entering uterus
3) Thins the endometrium - preventing implantation of the pregnancy

66
Q

What are likely differentials for menorrhagia?

A

1) FIBROIDS
2) Endometriosis
3) Cervical/endometrial polyp
4) Dysfunctional uterine bleeding
5) PID

7) Endometrial carcinoma
8) Contraception?
Non gynae: Blood dyscrasia? (von Willebrand), hypothyroidism

67
Q

What are the 3 ways of managing a Breech presentation?

A

1) External Cephalic Version - ctg and scan, then lie on bed and trained drs and midwives press on tummy and then get you to sit up (gravity), which will hopefully cause baby to turn into a head down first position. Give Anti-D Ig. Give terbutaline if tense and contracting.
2) Elective c-section
3) Elective vaginal breech delivery *NO INDUCTION of labour, EPIDURAL may increase risk, continuous fetal monitoring*

68
Q

When do we offer ECV to mothers with a breech baby?

A

36 weeks for primips, 37 weeks for multiparous women

69
Q

What stage of pregnancy do women create a birth plan?

A

34 weeks

70
Q

What are the risks of a vaginal breech delivery?

A

Increased risk of fetal death, head entrapment, cerebral palsy, healthcare professionals also have less experience currently

71
Q

What are the risks of a C-section?

A

Increased immediate complications for mother, risk of complications in future pregnancy, including the risks of opting for VBAC, the increased risk of complications at repeat caesarean section and the risk of an abnormally invasive placenta.
For subsequent pregnancies, having had a planned caesarean (compared with planned vaginal) birth causesa three-fold increase in uterine scarring; more than half of all women with at least one prior caesareansection have another.25The risks of blood transfusion, endometritis, hysterectomy and death are increasedin women with a previous caesarean section (irrespective of whether they attempt a VBAC) whencompared with those who have previously delivered vaginally.22The risk of scar rupture during attemptedvaginal birth after one caesarean section is approximately 0.5%.22,26,27In developing countries, particularlywhere birth outside hospital is usual and access to healthcare is poor, the effect on maternal outcomes islikely to be considerably greater.28A further maternal issue is that of placenta praevia and placenta accreta,29or abnormally invasiveplacentation, for which prior caesarean delivery is the principal risk factor. The risk of abnormally invasiveplacentation increases from 0.31% with one prior caesarean section to 2.33% with four30and the incidenceis rising. The risk is higher after elective compared with emergency caesarean section.31 This complicationcan lead to massive haemorrhage, hysterectomy, urinary tract injury and maternal death.

72
Q

What is the efficacy of ulipristal acetate (ella1)?

A

Around 98-99% - more effective within the 72-120 hr window than Levonelle

73
Q

What are the 4 stages of endometriosis?

A

Stage 1 or minimal: There a few small implants or small wounds or lesions. They may be found on your organs or the tissue lining your pelvis or abdomen. There’s little to no scar tissue.
Stage 2 or mild: There are more implants than in stage 1. They’re also deeper in the tissue, and there may be some scar tissue.
Stage 3 or moderate: There are many deep implants. You may also have small endometriomas on one or both ovaries, and thick bands of scar tissue called adhesions.
Stage 4 or severe: This is the most widespread. You have many deep implants and thick adhesions. There are also large endometriomas on one or both ovaries.

Laparoscopy with fimbrial biopsy and culture

88
Q

How can acute PID lead to chronic PID?

A
  • Persisting infection
  • Tx failure
  • Reinfection through sexual partners
89
Q

What are the features of chronic PID?

A

Dense pelvic adhesions
Hydrosalpinx
Pyosalpinx
Obstructed fallopian tubes

Causing: cervical excitation, adnexal discomfort

90
Q

What is the tx for chronic PID?

A

1) Analgesics
2) Abx - ceftriaxone, doxycycline, metronidazole

Atrophic vaginitis
Ectropion/erosion
Polyp
Cervical carcinoma - usually with abnormal vaginal bleeding too

92

A

Ix: Obs, FBC - WBC, CRP
Microscopy and culture of abscess material - sterile /polymicrobial
In women over 40, biopsy of vulval lesion - may be a bartholin gland cancer

A

Mucous cyst
Vulval haematoma
Vulval fibroma
Vulval lipoma
Cyst of canal of Nuck
Epidermal inclusion cyst
Malignant lesion of Bartholin’s gland
Genital/vulval warts (condylomata acuminata)
Vulval carcinoma
Vulval intraepithelial neoplasia
Congenital vaginal cyst

95
Q

What is the tx for Bartholin’s cyst?

A

Asymptomatic - conservative management - wash with warm water only
soak with warm flannel
warm compresses
sitz baths

Symptomatic -
Medical treatment - Broad spectrum Abx - trimethoprim/sulfamexazole or amoxicillin/clavulanate + clindamycin
Surgical tx - Marsupialisation
Catheter drainage - word catheter

Bartholin’s abscess -
Conservative management +/- incision and drainage
Broad spec Abx
After infection/inflammation controlled: Marsupialisation/catheter drainage

96
Q

What is VIN?

A

Vulval intraepithelial neoplasia (premalignant condition of the vulva).
Divided into 2 types: usual and differentiated.
Usual is most common - can be warty, basaloid or mixed - more common in women 35-55. HPV, CIN, cigarette smoking and chronic immunosuppression are RF.

97
Q

What is the tx for VIN?

A

Conservative: Emollients
Medical: mild topical steroid
Surgical: local surgical excision - relieves sx, confirms histology and excludes invasive disease.

98
Q

What are the Ix for vulval carcinoma?

A

Bloods: FBC, U&E, G&S
Imaging: CXR
Other: ECG
Biopsy of lesion

99
Q

How do the progesterone implants work as contraceptives?

A

Both versions slowly releases the progestogen hormone etonogestrel. They are typically inserted in the proximal non-dominant arm, just overlying the tricep. The main mechanism of action is preventing ovulation. They also work by thickening the cervical mucus.

Implanon has been replaced by nexplanon - (newer - better - more superficial insertion)

100
Q

What is the most effective form of contraception?

A

The contraceptive implant (nexplanon)

Has a failure rate of 0.7/1000

101
Q

What are the adverse effects, drug interactions and contraindications to the contraceptive implant (Nexplanon)?

A

Adverse effects

irregular/heavy bleeding is the main problem: this is sometimes managed using a co-prescription of the combined oral contraceptive pill. It should be remembered to do a speculum exam/STI check if the bleeding continues

‘progestogen effects’: headache, nausea, breast pain

Interactions

enzyme-inducing drugs such as certain antiepileptic and rifampicin may reduce the efficacy of Nexplanon

the FSRH advises that women should be advised to switch to a method unaffected by enzyme-inducing drugs or to use additional contraception until 28 days after stopping the treatment

Contraindications

UKMEC 3*: ischaemic heart disease/stroke (for continuation, if initiation then UKMEC 2), unexplained, suspicious vaginal bleeding, past breast cancer, severe liver cirrhosis, liver cancer

UKMEC 4**: current breast cancer

102
Q

Explain how tamoxifen can cause endometrial hyperplasia?

A

Tamoxifen is used for oestrogen receptor-positive breast cancer, in the breast, it has anti-oestrogenic effects. However, on the endometrium, it has pro-oestrogenic effects. This effect, if unopposed by progesterone, can result in endometrial hyperplasia.

103
Q

What is the vaginal pH in bacterial vaginosis infection?
