Q

What is uterine artery embolisation?

A

**MEDICAL EMERGENCY** Ovary **twists** in relation to the **adnexa** (surrounding connective tissue, fallopian tube & blood supply)
31
What is the pathophysiology of ovarian torsion?
* Usually due to **ovarian mass** >5cm / normal ovaries in younger girls before menarche (longer **infundibulopelvic ligaments** that can twist more easily) * Twisting of adnexa & blood supply to ovary = **ischaemia** * If torsion persists = **necrosis** = function lost

What is the pathophysiology behind pelvic pain in endometriosis? ## Footnote Pelvic pain = Main Sx
* Cells of endometrial tissue **outside uterus** respond to hormones in same way as tissue **inside** the uterus * During menstruation endometrial tissue in uterus **sheds lining** & **bleeds** - same happens in endometrial tissue **elsewhere in body** * This causes **irritation** & **inflammation** of tissues around sites of endometriosis * Results in **cyclical**, **dull**, **heavy**/**burning pain** that occurs during menstruation
111
How does endometriosis cause adhesions?
* Localised **bleeding** & **inflammation** - causes damage and deveopment of **scar tissue** that binds organs together * Adhesions lead to **chronic**, **non-cyclical pain** that can be sharp/stabbing/pulling & associated w/ nausea

115
What is adenomyosis?
**Endometrial tissue** inside the **myometrium** * **Hormone-dependent**, Sx tend to resolve after menopause (like endometriosis/fibroids) * Can occur alone, or alongside endometriosis/fibroids * More common in **later reproductive years** & those that have had **multiple pregnancies**

121
What is atrophic vaginitis
**dryness and atrophy** of the vaginal mucosa related to a lack of oestrogen.
122
Why does atrophic vaginitis usually occur in menopause
**LACK OF OESTROGEN during menopause** - usually Epithelial lining in the vagina and urinary tract responds to oestrogen by getting thicker, producing secretions and being elastic -less oestrogen means tissue is more prone to inflammation and infection
123
Presentation of atrophic vaginitis
Itching Dryness Dyspareunia (discomfort or pain during sex) Bleeding due to localised inflammation **Post menopausal women:** Recurrent UTI Stress incontinence Pelvic organ prolapse
124

-thickened rough dark skin typically on elbows and armpits -due to INSULIN RESISTANCE
132
What are DDX for hirsutism
-PCOS -ovarian/adrenal tumours -cushings -congential adrenal hyperplasia -medications e.g phenytoin, ciclosporin, anabolic steroids, corticosteroids, artificial testosterone
133
How does insulin resistance occur in PCOS
**Insulin resistance is both a symptom and a driver for PCOS** -Insulin resistance means pancreas has to produce more insulin to get the same response -**insulin also promotes androgen release e.g testosterone** + suppresses **sex hormone binding globulin** which usually suppresses androgens -this can lead to hyperandrogenism in women with PCOS and poor development of follicles in the ovaries
134
Ix for PCOS
Blood tests: -**raised LH** -**raised LH-FSH ratio (high LH compared to FSH)** -raised testosterone -raised insulin -normal/raised oestrogen -low sex hormone binding globulin Exclude other pathology -prolactin -TSH Pelvic ultrasound GOLD STANDARD - Transvaginal ultrasound for observing ovaries - **string of peals appearance** 2hr oral glucose tolerance test- test for insulin resistance

138
How does PCOS increase the risk for endometrial cancer
-in PCOS patients dont experience regular menstruation -so endometrial lining continues to proliferate under the influence of oestrogen and **does not shed** -resulting in endometrial hyperplasia a pre cancerous stage of endometrial cancer
139
Management of the risk of endometrial cancer in PCOS
Mirena coil: thin the lining of the uterus Inducing a period: -cyclical progestrogens e.g medroxyporgesterone acetate once a day For 14 days -COCP
140
How do you manage the infertility in PCOS
First step: Weight loss If this fails: Letrazole(aromatase inhbitor) first line drug - increases FSH and LH levels Laparscopic ovarian drilling IVF Metformin - increases insulin sensitivity
141
Management for hirsutism in PCOS
Weight loss **Co-Cyprindiol**- COCP for the treatment of hirsutism and acne Topical eflornithine - 6/8 weeks Electrolysis Laser hair removal Spironolactone Finasteride - decreases testosterone Flutamide Cypoterone acetate - anti androgen and progestin
142
Management of acne in PCOS
first line - COCP Co-cyprindiol may be the best option as it has anti-androgen effects Topical adapalene Topical Abx Topical azelaic acid Oral tetracycline
143

Significantly increased risk of VTE

179
What is classed as premature menopause
Menopause before the age of 40
180
What are the changes to the sex hormones during menopause
Oestrogen - low Progesterone - low LH + FSH - high due to lack of negative feedback
181
What is the physiology of menopause
begins with a decline in the development of the ovarian follicles. Without the growth of follicles, causes reduced production of oestrogen. Oestrogen has negative feedback effect on the pituitary gland, suppressing the quantity of LH and FSH produced. As the level of oestrogen falls in the perimenopausal period, there is an absence of negative feedback on the pituitary gland, and increasing levels of LH and FSH. Leads to irregular menstrual cycles
182
