Q

Cervical Screening

A

Prevention of disease of female genital tract
- Participation by a 35-64 yr old woman = 60-80% reduced risk of cervical cancer over the next five years = 90% reduced risk of advanced cervical cancer
PAP smear is one of the most effective screening tests ever
Major contributor in the significant reduction of both the Incidence and Mortality of cervical cancer

Q

Oral contraceptive pill

A

used by more than 10 million woman worldwide
Uses vary by ocuntry, age, education, and marital status
Functions: decrease menstrual cycle pains, endometrial/ovarian cancer risk, duration and volume of menstrual bleeds –> preventing depletion of iron stores, hence decreased risk of female anaemia
-One of the main contributors to womans health
1/3 UK woman aged 16-49, currently used either Combined pill or Progesterone-only pill

Q

Components of Gynaecological examination

A
  1. General and abdominal examination
  2. Pelvic examination: Use Speculum —> distends vaginal cavity –> can look at cervix
    - Bimanual (Cervix, cervical motion tenderness, uterus and adnexa)
19
Q

Pelvic Examination illustrating infection

A

Chlamydia

  • inflamed cervix with white discharge
  • 8% of woman (1/12)
  • auckland has highest rates
  • Ascends to tubes –> pelvic infectious disease –> chronic –> impact on future fertility
  • therefore prevention via:
    1. Oral contraceptive pill
    2. Being aware that contraception isnt sufficient protection –> male Must use condom
20
Q

Gynaecological Investigations

A
  1. Urine sample
  2. Cervical smear
  3. Vaginal swabs ( t. vaginalis, N. gonorrhoeae, C. trachomatia) Note: increasing resistance to diarrohea in auckland
  4. Biopsy (pipette): insert noting depth of fundus and withdraw plunger until “stopped” to create vaccum
  5. Ultrasound
21
Q

Heavy Menstrual Bleeding

A
  1. Prevalence: 1/5 woman in reproductive age
  2. Health care use: 5% of all GP visits (increasing as people dont know what to do). 35% of all referrals to Gynaecologists. 30% of all gynaecological surgeries (to alleviate/stop heave menstrual bleeding)
  3. Structural Causes: PALM (diseases can effect the shedding of the uterus lining)
    - Polyp, Adenomyosis, Leiomyoma (fibroids), Malignancy and hyperplasia
22
Q

Uterine Fibroids

A

Type of structural cause of heavy menstrual bleeding
1. Epidemiology: Common (15-20%) reproductive age. Estrogen dependant. Regress into postmenopause. OCP proteins (can interfere with fertility?)
2. Pathophysiology: Benign leiomyomata arising from the uterine myometrium
- interfer with blood flow from the uterus
-1:3 woman over 35 years
3. Symptoms: Abnormal uterine bleeding, pelvic discomfort, No pain
–> Fibroids are only a problem if you are EXPERIENCING Pain
Note: Anterior fibroids can affect the bladder

23
Q

Treatment of Uterine Fibroids

A
  1. Conservative: Expectant, unless significant menstrual bleeding problems, pressure symptoms and rarely infertility
  2. Medical: NSAIDS during menstrual period. Mirena if fibroids are small and not submucosal. GnRH analagous
  3. Invasice: a) Myomectomy (fibroid resection)(Hysteroscopic, Abdominal/Laprascopic) b) Hysterectomy c) Uterine Artery Embolisation
    Note: Treatment can differ b/w public and private healthcare, purely due to money insentives
24
Q

Structural Causes of Heavy Menstrual Bleeding

A

Structural Causes: PALM (diseases can effect the shedding of the uterus lining)
- Polyp, Adenomyosis, Leiomyoma (fibroids), Malignancy and hyperplasia

25
Q

Non-structural causes of Heavy menstrual bleeding

A

COEIN

  • Coagulopathy
  • Ovulatory dysfunction
  • Endometrial
  • Iatrogenic
  • Not yet calssified
26
Q

Treatment for Acute Heavy Menstrual Bleeding (HMB)

A
  1. Progestogens: high dose for 10 days
  2. Tranexamic acid:
    a) 5x day Oral dose: 2x 500-625 mg tabs
    b) IV dose: 10mg/kg bd
  3. 3 months of: (continue cycle regulation for 3x months until have stopped bleeding)
    a) Oral contraceptive (days 0-22 of cycle)
    b) Progestogens (day 5-25 of cycle)
27
Q

Functions of Progestogens (on endometrium)

A
  1. Stops estrogen induced growth of the endometrium (stabilises)
  2. Stabilizes endometrial vasculature and blocks unrestrained vessel growth
  3. Initiates the clotting cascade (coagulation promoted)
  4. Homeostatic and anti-fibrinolytic action (PA-I pathway)
  5. Inhibits matrix metallo-proteinase activity
28
Q

Function of Tranexamic Acid

A

Normal: Anticoagulation/anti-clotting release occurs in initial days of menstruation –> allows clot breakdown so inner lining can be shed –> blood easily flows out
HMB: Excessive Anticoagulation/anti-clotting factor release –> Excessive clot breakdown –> Excessive HMB
Therefore HMB Clotting treatment: (decreased clot breakdown)
HMB –> prescribe Tranxemic acid (anti-fibrinolytic) –> decreased plasminogen conversion into plasmin –> decreased degradation of fibrin clot –> decreased ease of blood flow –> HMB

29
Q

Clotting diagram

A

Fibrinogen –Thrombin –> Fibrin clot

Fibrin Clot – (Plasminogen –> Plasmin) –> Fibrin Degradation

30
Q

Endometrial Ablation

A

Endometrial Ablation is required if no pathology and compliant medical management has failed for atleast 3 months

  • Minor procedure: destroys (abalates) the uterine lining / endometrium
  • Short recovery time
  • 80% satisfaction rate
  • 25% have repeat procedure or subsequent hysterectomy
31
Q

Options if initial HMB medical management has been compliantly followed, and no pathology, has failed for 3 months

A
  1. Endometrial ablation

2. Hysterectomy

32
Q

Hysterectomy

A

Endometrial Ablation is required if no pathology and compliant medical management has failed for atleast 3 months

  • Major procedure (removes all/majority of uterus)
  • Significant possible consequences: Bleeding, infection, Re-operation, Chronic Pelvic pain
  • Required 6-8 weeks recovery (regardless of route)
  • High satisfaction rate overall
33
Q

Stress Incontinence

A
  • Increased intra-abdominal pressure –> external intra-abd pressure exceeds outwards pressure of uterine wall –> *Relaxed pelvic Floor –> bladder closing mechanism not working well –> urine leaks
  • repair can occur
  • increased abdominal pain
  • e.g. netballers, bballers, women lifting something
  • 45-50 year old woman
34
Q

Urge incontinence

A

Infection –> Neurological disorder –> Bladder has become over sensitive –> Constant feeling of needing to/urge to pee
- Alcohol and Drugs = take away irritability of nerve which regulate bladder function

35
Q

Overflow incontinence

A

Urethral blockage –> Bladder unable to empty properly

36
Q

Painful conditions of Gynaecology

A 
Dysmenorrhea (period pain)
Dyspareunia (sex pain)
Oculation bleeding
Ectopic pregnancy
Torsion of the overy (180 degrees --> blood supply closed)
Miscarriage
Endometriosis
37
Q

Painful Gynaecological condition of Dysmenorrhea

A

Painful menstrual periods
Prevalance 45-72%
Menarche + 3 years: first three years of menstrual cycle = 1/2 of young girls have dysmenorrhea
Analgesics 39% (NSAIDS: ibprofen))

38
Q

Endometriosis

A 
Upto 1/10 women which MUST BE IN REPRODUCTIVE AGE
- Most painful condition on Gynaecology
6x pain types assoc w. endometriosis:
1. Painful periods (dysmenorrhoea)
2. Painful sex (dyspareunia)
3. Pain on opening bowels (dyschezia) --> Bloating
4. Pain on passing urine (dysuria)
5. Mid cycle/Ovulatory
6. Chronic Pelvic Pain
39
Q

Diagnosis of Endometriosis

A

Can only diagnose Endometriosis via an Invasive procedure under general anaesthetic (Lasparoscopy)
- Black spots are typical for endometriosus
Want to avoid invasive procedure –> therefore try and confirm via other methods that it is actually endometriosis
- Oral contraceptive pill for atleast 6 months
- No elevation: Is either 1. Pain due to a Non-gynaecological cause 2. Endometriosis assoc. pain

40
Q

Endometriosis Aetiology

A 
Disease characterised by function extra-uterine endometrium
i.e. Endometrium sheds --> but some travels through uterine tubes (instead of towards cervix) and inserts into abdominal cavity --> implantation --> tries to cycle/develop in same way as it's brother/sister cells do in the womb ( functional extra-uterine endometrium)
RETROGRADE menstruation (VASCULAR/LYMPHATIC spread)
41
Q

Endometriosis Treatment

A
  1. Explanation and multidisciplinary approach
  2. Pain management - Holistic approach
  3. Medical: Progestogen hormonal suppression of endometrial cells –> Inhibit any further activation of endometriotic lesions
    - Mirena
  4. Surgical: Laparoscopic excision of endometrial deposits
  5. Definitive surgery: Hysterectomy and Bilateral Salpringo- oopherectomy
42
Q

When can you have endometriosis

A

When you are within Reproductive lifespan (for however long within the life span)

  • therefore not before menarche or after menopause
  • Chronic condition
43
Q

Endometriosis Prognosis

A

Tendency to progress and recur after medical treatment
May even recur after radical surgery, although rare
Regression in pregnancy and in postmenopause

44
Q

Most common Gynaecological conditions

A

Heavy menstrual bleeding
Fibroids
Continence issues
Endometriosis
