Gynae Flashcards
What is PMS?
psychological, emotional and physical symptoms that occur during the luteal phase of the menstrual cycle, particularly in the days prior to the onset of menstruation.
When do PMS symptoms resolve?
When menstruation begins
What causes PMS?
Fluctuation in oestrogen and progesterone. May be due to increased sensitivity to progesterone.
PMS presentation (7)
Low mood Anxiety Fatigue Mood swings Irritability Breast pain Reduced Libido
Can PMS symptoms occur after hysterectomy/endometrial ablation/Mirena Coil? and Why?
Yes, since ovaries continue to function and hormonal cycle continues.
PMS diagnosis?
Symptom diary spanning 2 menstrual cycles.
Definitive diagnosis may be made with GnRH analogues to halt menstrual cycle and see if symptoms resolve.
PMS management? (4)
Lifestyle: Diet, exercise, alcohol, sleep
COCP
SSRI antidepressants
CBT
What COCP is recommended by RCOG?
COCP containing drospirenone (i.e. Yasmin), it contains anti-mineralocorticoid effects, similar to spironolactone

What are fibroids?
Benign smooth muscle tumours of uterus
What is the relationship between fibroids and oestrogen
Oestrogen sensitive -> grow in response to oestrogen
What are the types of fibroids
Intramural, Subserosal, Submucosal, Pedunculated

Abdominal and bimanual examination (palpable pelvic mass/ enlarged non-tender uterus)
Hysteroscopy (submucosal fibroids)
Pelvic ultrasound
MRI (size, shape and supply to fibroids - before uterine artery embolisation)
Fibroids management <3cm ? (7)
Mirena coil
NSAIDs and Tranexamic acid

Cyclical oral progestogens
Endometrial ablation
Resection
Hysterectomy
Fibroids management >3cm? (3)

Myomectomy
Hysterectomy
Name 2 GnRH
Goserelin, leuprorelin
What is red degeneration?
Ischaemia, infarction and necrosis of fibroid due to disrupted blood supply
Red degeneration presentation? (4)
Severe abdominal pain, Low grade fever, tachycardia, vomiting
Red degeneration management?
Rest, Fluids, analgesia
What is endometriosis?
Condition where endometrial tissue present outside uterus
Endometriosis causes?
Unknown, theory is retrograde menstruation where endometrial lining flows backwards through fallopian tubes and into pelvic and peritoneum. Endometrial tissue seeds itself in pelvis and peritoneal cavity.
Pathophysiology of Endometriosis
Ectopic endometrial tissue responds similarly to regular endometrial tissue. During menstruation ectopic tissue also sheds and bleeds causing irritation and inflammation at sites
Endometriosis presentation (7)
Cyclical abdominal/pelvic pain Deep dyspareunia Dysmenorrhea Infertility Haematuria Urinary symptoms Bowel Symptoms
Endometriosis investigations
Pelvic speculum and bimanual examination (vagina, cervix, adnexa tenderness, fixed cervix on BM examination, endometrial tissue visible on speculum examination)
Pelvic ultrasound (large endometriomas and chocolate cysts)
Laparoscopic surgery and biopsy
Endometriosis Staging?
S1-> small superficial lesions
S2->mild but deeper lesions than S1
S3-> Deeper lesions with lesions on ovaries and mild adhesions
S4-> Deep and large lesions affecting ovaries with extensive adhesions
Endometriosis management
Analgesia (NSAIDs, Paracetamol)
COCP, Mirena coil, Progesterone only pill, GnRH agonists, Medroxyprogesterone acetate injection (depo-Provera)
Laparoscopic excision/ablation, Hysterectomy and bilateral salpingo-ophrectomy
What is adenomyosis?
Endometrial tissue inside myometrium
Adenomyosis presentation
Dysmenorrhoea, Menorrhagia, Dyspareunia, potential infertility
Adenomyosis Investigation
Pelvic examination
Transvaginal ultrasound
MRI and transabdominal ultrasound
Histological examination through hysterectomy
Adenomyosis management
Tranexamic acid/Mefenamic acid
Mirena coil, COCP, COP
GnRH analogues, Endometrial ablation, Uterine artery embolisation, Hysterectomy
Complications of Adenomyosis (6)
Infertility, Misscarriage, preterm birth, Small gestational age, PROM, malpresentation
Menopause?
point at which menstruation stops
Age for menopause normally?
51.2 years
Menopause cause
Lack of ovarian follicular function so oestrogen, progesterone low /and FSH and LH high
Pathophysiology of menopause
Decline in development of ovarian follicles. Without growth, there is reduced oestrogen.
Perinmeopausal symptoms
Hot flushes, Irregular periods, joint pain, vaginal dryness and atrophy, reduced libido, emotional lability/low mood
Risks after menopause?
Cardiovascular disease and stroke, Osteoporosis, Pelvic organ prolapse, urinary incontinence
How is menopause diagnosed?
Made only in women over 45, using FSH
Depo-Provera side effects
Weight gain, osteoporosis
Perimenopausal management
HRT, Tibolone (steroid), Clonidine (alpha-adrenergic agonist), CBT, SSRI, Vaginal oestrogen
Premature ovarian insufficiency?
Menopause before the age of 40 years
Premature Ovarian Insufficiency causes
Idiopathic (50%), iatrogenic (chemo, radio, oophrectomy) , autoimmune, genetic, infections
Presentation of premature ovarian insufficiency
Irregular menstrual period, hot flushes, night sweats, vaginal dryness
Diagnosis of Premature ovarian insufficiency
FSH persistently raised on 2 consecutive samples 4 weeks apart (>25IU/L)
Management of Premature ovarian insufficiency
HRT
Clonidine side effects
dry mouth, headaches, dizziness and fatigue
PCOS?
condition causing metabolic and reproductive problems in women
What criteria used to diagnose PCOS and what are they?

Ovarian torsion?
Condition where ovary twists in relation to surrounding connective tissue, fallopian tube and blood supply
