|
Define menorrhagia
Name some causes |
Heavy menstrual bleeding > 80mls per period
OR periods lasting > 7 days Endometrial polyps Dysfunctional uterine bleeding Endometrial hyperplasia Fibroids Adenomyosis Endometriosis Chronic PID |
|
Define dysmenorrhea
Name some causes |
Menstrual pain in absence of organic disease (primary)
Menstrual pain due to organic disease (secondary) Endometriosis, fibroids, PID, adenomyosis, PCOS |
|
Define dysfunctional uterine bleeding
|
Abnormal bleeding not attributable to organic (anatomic/systemic) disease
DUB is a diagnosis of exclusion |
|
Define oligomenorrhea
|
irregular cycle more than 35 days in length
|
|
Describe a normal menstrual cycle
Days, amount of blood |
28 days - lasting 3-5 days, 30-50mls
|
|
Differential diagnosis for abnormal uterine bleeding that is typically cyclic
|
Anatomic or physical lesion (Polyp, Fibroid, Adenomyosis, Neoplasm, foreign body)
Haemostatic defect Infection Trauma local disturbances in prostaglandins |
|
Differential diagnosis for abnormal uterine bleeding that is unpredictable
|
PCOS
Thyroid dysfunction Elevated prolactin Rare oestrogen producing tumours Stress Wt loss Exercise Liver and kidney disease |
|
Define metorrhagia
|
bleeding at irregular intervals, particularly between expected menstrual periods
|
|
Define polymenorrhea
|
vaginal bleeding occurring at intervals < 21 days
|
|
Treatment for dysfunctional uterine bleeding?
|
If acute haemorrhage - give IV oestrogen to stop bleeding (raises DVT risk)
Chronic DUB - NSAIDs (decreases blood loss by 20-50%) In anovulatory women - hormonal therapy via oestrogen and progesterone OCPs, Mirena Surgical - DC, if fertility is no longer needed can have uterine endometrial ablation to destroy uterine tissues, hysterectomy - definitive treatment |
|
Main causes of dysfunctional uterine bleeding
|
Anovulation 90%
Dysfunction of corpus luteum and inadequate progesterone production or an atrophic endometrium (i.e. secondary to OCP) |
|
Definition of endometriosis
|
The presence of endometrial tissue (glands and stroma) outside of the uterine cavity
It affects 10-15% of menstruating women |
|
Pathogenesis of endometriosis
|
Not fully understood
1. Retrograde theory of Sampson: seeding of endometrial cells by transtubal regurgitation during menstruation 2. Immunologic theroy - altered immunity may limit clearance of transplanted endometrial cells from pelvic cavity 3. Undefined endogenous biochemical factor may induce undifferentiated peritoneal cells to develop into endometrial tissue 4. Lymphatic flow from uterus to ovary 5. Vascular or lymphatic dissemination of cells |
|
Risk factors for endometriosis
|
FHx
Obstructive anomalies of the genital tract Nulliparity Age > 25 years |
|
Which sites does endometriosis occur?
|
Ovaries
broad ligament - vesicoperitoneal fold periteonal surface of the cul-de-sac (uterosacral ligaments) rectosigmoid colon appendix |
|
Symptoms of endometriosis
|
Dysmenorrhea
Dyspareunia Dyschezia (difficulty defecating) Dysuria, frequency, haematuria Infertility |
|
What investigations should be done in suspected endometriosis
|
Definitive diagnosis - direct visualisation of lesions at laparoscopy + biopsy and histologic exam of specimens
CA125 may be elevated |
|
Medical treatment of endometriosis
|
NSAIDs - reducing pain
Pseudopregnancy - OCP; depoprovera Psuedomenopause - danazol - weak androgen; leuprolide - GnRH agonist Medical treatments have common adverse effects and do not improve fertility (second line only < 6 months due to osteoporosis |
|
Surgical treatment of endometriosis
|
Conservative laparoscopy using laser, electrocautery +/- laparotomy
- best time to become pregnany is immediate after above surgery Bilateral salpingo-oophorectomy +/- hysterectomy Beneficial for infertility, possibly better long term results, but expensive and invasive |
|
Common causes of dyspareunia
|
Intraoital - inadequate lubircation, vaginismus, rigid/intact hymen, vulvovaginitis (atrophic, chemica, infectious)
Lichen sclerosis Midvaginal - urethritis, short vagina, trigonitis (squamous metaplastic changes that occur in the bladder) Deep - endometriosis, adenomyosis (extension of endometrial glands and stroma into the myometrium), leimyomata, PID, uterine retroversion, ovarian cyst |
|
List the causes of infection in the upper/lower genital tract
|
Lower:
Vulvovaginitis: Candidiasis; Bacterial vaginosis - Gardnerella vaginalis; Trichomoniasis (sexually transmitted) - trichomonoas vaginalis; Chlamydia; Gonorrhea; HSV; syphillis Upper: PID: (in order of frequency) Chlamydia, Gonorrhea, Endogenous flora (E. Coli, Staph, Strep, Enterococcus, Bacteroides - associated with instrumentation), Actinomyces israelii (associated with IUDs) |
|
Symptoms of PID
|
2/3 asymptomatic
Common: fever, lower abdominal pain and tenderness, abnormal discharge - cervical or vaginal Uncommon: N/V, dysuria, AUB Chronic (often due to chlamydia): constant pain, dyspareunia, palpable mass, ON examination - must have cervical motion or adenxal tenderness |
|
Causes of acute pelvic pain
|
Complications of pregnancy: ectopic, miscarriage
Acute infection: endometritis, acute PID, tubo-ovarian abscess, pelvic thrombophlebitis Adnexal mass: ovarian torsion, ruptured ovarian cyst, endometriosis, |
|
Causes of chronic pelvic pain
Continous pain > 6 months |
Gynae:
Chronic PID; endometriosis; adenomyosis; fibroids Surgical Chronic appendicitis; diverticulitis, IBD, IBS, calculi |
|
How do you treat PID?
|
FOXY DOXY
Cefoxitin and doxycyline |
|
Investigations in chronic pelvic pain?
|
FBC - infection, anaemia
Transvaginal and abdominal US B-HCG CA-125 Alpha fetoprotein and LDH |
|
How do you screen for chlamydia and gonorrhea
|
