25
Risk factors for pelvic inflammatory disease
Earlier untreated sexually transmitted disease, or having multiple sex partners
26
pelvic inflammatory disease develops when
Pathogens ascend from an infected cervix to infect fallopian tubes
27
Main sexually transmitted infections
Gonorrhoea and chlamydia
28
Aerobic bacteria alter vaginal pH =
Decrease integrity of mucus blocking cervical canal
29
TX pelvic inflammatory disease
Broad spectrum antibiotics to ensure all causative agents are eliminated
30
Salpingitis
Inflammation of fallopian tubes -changes columnar epithelia of upper reproductive tract
31
Salpingitis causes
Local edema and possibly necrosis
32
Gonorrhoea and chlamydia in Salpingitis
G: attach to fallopian tubes and secrete a toxin that damages mucosa C: enters damaged cells and replicates = pathogens burst cell membrane causing scarring
33
Chronic consequences of PID
Infertility, tubul obstruction, ectopic pregnancy
34
Vaginitis
Vaginal inflammation with inc of WBC
35
Vaginosis
Vaginal irritations without WBC
36
Causes of vaginitis
Overgrowth of normal flora -STI -low estrogen levels during menopause
37
vaginitis is related to alterations in
Vaginal pH -normal levels of 4 to 4.5 depending on cervical secretions and presence of normal flora -changes in pH = predisposition to infection
38
Diagnosis of vaginitis
Change in colour and amount of menstrual discharge
39
TX for vaginitis
Support acidic environment -probiotics encourage proliferation of normal vaginal flora
40
Cervicitis
Inflammation of cervix
41
Diagnosis fo Cervicitis
1. Purulent discharge (pus) 2. Mucopurulent discharge (pus and mucus)
42
Mucopurulent Cervicitis
Infection becomes red and edematous (related to or affected by edema) -drains from external cervix -pelvic pain -bleeding may be present
43
Mucopurulent Cervicitis is a symptom of
Pelvic inflammatory disease
44
Women under 26 yoa should receive
TX for PID while waiting for exudate examination
45
Benign ovarian cysts occur in
Reproductive years around puberty and menopause
46
Benign ovarian cysts are related to
Hormone imbalances -reason for 1/3 gynaecological hospital admissions
47
Two causes for Benign ovarian cysts
Ovary/follicular cysts and corpus luteum cysts
48
During normal menstrual cycle ___ follicles are stimulates
120 -but only one reaches ovulation
49
Follicular cyst
Dominant follicle does not rupture normally, or non dominant follicles do not regress
50
Ovary cysts
Development occurs when no dominant follicle develops and completes maturation process
51
Corpus luteum cysts
May form from granulosa cells left behind after ovulation
52
Endometriosis
Presence of functional endometrial tissue outside uterus -ovaries, fallopian tubes, bladder
53
Problem with functional endometrial tissue outside uterus
Tissue still responds to menstrual cycle hormonal fluctuations -causing infertility and pain
54
Endometriosis causes
-high levels of estrogen -cells switching fates during development -new bv to support lesions (angiogenesis) -stem cells play role -ectopic pregnancy
55
Second leading cause of death in women, with an 1 in 8 chance of development
Breast cancer
56
On average per day, __ canadian women will be diagnosed with breast cancer and ___ will die from the cancer
75, 14
57
In 2022 ___ men will be diagnosed with breast cancer, and __ will likely die from breast cancer
240, 55
58
Four hypothesis for breast cancer
1. Ovarian androgen (testosterone) excess 2. Blood elevation in both estrogen and progesterone 3. Estrogen alone : estrogen circulating in breast cancer in post menopausal women 4. Local biosynthesis of estrogen in breast tissue
59
Diagnosis of breast cancer
Clinical breast exam, mammography, biopsy
60
Risk factors for breast cancer in women
BRCA1 and BRCA2 gene mutation -normally these protect against cancer but mutations lead to cancer Family history Menstruation before 12 yoa Menopause after 55 yoa Nulliparou (no children) Oral contraceptives Obesity
61
Hormonal factors of breast cancer in women
-progesterone affects early first pregnancy or removal of ovaries and pituitary gland -inc risk associated with early menarche, late menopause, nulliparity
62
Gynecomastia
Overdevelopment of breast tissue in males -results in hormonal alterations
63
Who is at risk for Gynecomastia
Klinefelters syndrome -males with an extra X chromosome
64
Hormonal imbalance in Gynecomastia
Estrogen is very low or testosterone is very low
65
In young males Gynecomastia resolves in
4-6 months
66
Males > 60 yoa risks/Gynecomastia
-BRCA1 and BRCA2 mutations -nipple crusting and discharge -enlarged auxiliary nodes
67
TX for Gynecomastia
Modified mastectomy with hormone therapy
