Q

How does the cervix change during the menstrual cycle? (follicular phase + luteal phase)

A

Follicular phase –> ^ mucus production by cervix. Around ovulation, becomes more stringy + runny to facilitate sperm access.
Luteal phase –> becomes thicker + more elastic to protect the foetus from any microbes coming up vagina (mucus plug).

Q

Purpose of the corpus luteum? (which marks the Luteal Phase- 14days)

A

Corpus Luteum continuously produces progesterone –> stabilises endometrium, makes more viable for embryo to implant, ^endometrium’s secretions, lipids, glycogen + blood supply.

Q

What is adenomyosis and what are the key characteristics?

A

Ectopic endometrial tissue WITHIN the uterus (embedded in the myometrium).
Therefore- uterus will be bigger (symmetrical lumps on bimanual), painful ‘vague pain’ and heavy bleeding!

Q

Q

What causes vaginal atrophy, and how can it be managed?

Q

In PMB, investigating the endometrial thickness with USS- what are the cut off points for biopsy?

A

If >3mm (or >5mm on HRT!) then biopsy required! (as ^likelihood of endometrial ca.)
This DOESNT apply to women on Tamoxifen who have a thickened endometrium and require a hysteroscopy.

Q

Physiology of the Menopause?

A

(usually- developing follicles in ovaries produce estradiol)
As menopause approaches - ^anovulation, so progesterone levels drop.
Therefore, ^FSH +LH levels (as less estradiol, so less -ve feedback to anterior pituitary)

63
What are some risk factors for endometrial cancer?
(increased oestrogen, decreased progesterone) - Obesity! - Nulliparity - Early menarche, late menopause - Tamoxifen (oestrogen antagonist in breast, but agonist in uterus) - Oestrogen-only HRT (safest is the oestrogen-only patch) - HNPCC (FHx of breast, ovarian or colon)

72
Mode of action of Tamoxifen in pre and post menopausal women?
- Premenopausal: anti-oestrogenic effect (PROTECTIVE on breast + endometrial tissue) - Postmenopausal: still anti-oestrogenic effect on breast, however OESTROGENIC effect on endometrium, therefore ^risk endometrial ca.
73
What is the largest risk for a woman developing cancer?
OBESITY!!! | NOT HRT
74
Management of an unwanted pregnancy?
- hCG to confirm - USS (gestational age, viability, exclude molar/ectopic) - Bloods: Hb, ABO + Rhesus (women who are rh-ve will require anti-D) - Azithromycin 1g (prevents infection) - Counselling

78
What are some complications of TOP?
- Retained products of conceptions (persistent bleeding) - Failure: so importance of follow up. - Infection: prophylactic abx + advise warning signs. - Haemorrhage: more in later gestation. - Perforation of uterus/ cervical trauma: reduced by prostaglandins before to soften cervix. - Future fertility: not affected. - Psychological sequelae: no evidence, may need support.
79
When to refer for subfertility?
<36 and 1 yr of trying | >36 or abnormal Hx (amenorrhoea/PID)/ Ix in primary care and <1 year of trying.
80
What is the leading cause of subfertility in women?

82
General subfertility investigations in women?
- Midluteal progesterone (7 days before period- confirms presence of ovulation) - Chlamydia/STI test - USS of area - FSH, LH + oestrodiol levels - Thyroid + prolactin levels - Hysteroscopy (if expecting structural problems/ polyp on USS) - Rubella immune or not
83

87
What is the gold standard to test Tubal Infertility?
Laparoscopy: Lap + Dye ! | can also do hysterosalpingography
88
What is the management for anovulation?
Clomifene Citrate! (anti-oestrogen, causes release of FSH +LH. Trues to stimulate monthly ovulation) If also PCOS --> give Metformin too!!
89
Obs/Gynae Hx taking in urinary incontinence?
- Premenopausal (more likely URGE), or postmenopausal (more likely STRESS/ bigger issue like prolapse) - Vaginal atrophy causes urinary freq + UTIs - Problems with sex? (pain=endometriosis, prolapse etc) - Vaginal deliveries? (hints at more stress)
90
PMHx taking in urinary incontinence?
- Prolapse sx (mass/pain during sex) - Constipation - Chronic cough - Diabetes? - Neuro problems
91
Investigations in urinary incontinence?
- BMI - Urine dip - Abdo exam for any obvious masses - Cough whilst lying (look for leakage/prolapse) - Speculum (vaginal atrophy/fibroids) - Do smear if appropriate
92
How do anticholinergics and vaginal oestrogens work? (urge incontinence)
Anticholinergics: relax the bladder by blocking vagus nerve. | Vaginal oestrogens: post-menopausal women (if vaginal atrophy as the problem)
93
What physio can be used in urinary incontinence?
Pelvic floor exercises. At least 8 contractions 3xday, for 3months.
94
What is a medical treatment for stress incontinence?
Duloxetine ! (helps with tightening sphincter) | Also can use Bulkamid as urethral bulking agent (not as bad as surgery but still not great)
95
Percutaneious posterior nerve stimulation (PPNS)?
Posterior tibial nerve L4-S3, once a week for 12wks.
96
What if there is a mixture between stress and urge incontinence?
Always treat urge incontinence first because treating stress can make the symptoms of urge worse.
97
What does the Baden-Walker System grade?
It grades the extent of prolapse. | max possible descent: procidentia
98
Treatment for prolapse?
- Conservative mx: weight loss, avoid heavy lifting, pelvic floor exercises. - Pessary (reinforces position of everything) - Surgery (anterior/post repair, vaginal hysterectomy, sacrosponous fixation)
99
What is the risk of surgery for prolapse or stress incontinence?
It can just make urge incontinence worse !!!
