Lecture 7: Menstruation, Contraception, and Vaginal Infections Flashcards
1
Q
Menarche
A
First period
- starts at age of 12. range is (11-14.5)
- influenced by factors like race, genetics, nutritional status, body mass
2
Q
Period cycle
A
- Avg cycle is 28 days
- Range is 24-38 days,
- Generally 3-7 days
3
Q
Dysmenorrhea
A
painful menstruation
- prevalence is highest in adolescence, 93% affected
- generally develops within 6-12 months of menarche
4
Q
Premenstrual Syndrome
A
physical disorder or physical/emotional/behavioral changes that occur during luteal phase
5
Q
Amenorrhea
A
absence of menstruation
6
Q
Menorrhagia
A
abnormally heavy or prolonged bleeding
7
Q
metrorrhagia
A
abnormal bleeding from uterus
8
Q
oligomenorrhea
A
infrequent menstrual flow
9
Q
Primary dysmenorrhea
A
- appropriate to use self-care measures to treat
- as soon as 6-12 months after menarche but typically several years after
- no pain during other parts of cycle,
- more likely to be regular with normal blood loss
- NSAIDS help
10
Q
Prostaglandins
A
stimulate uterine contractions to expel menstrual fluid and control bleeding as the endometrium sloughs
11
Q
Leukotreines
A
cause vasoconstriction and uterine contractions
12
Q
Dysmenorrhea Risk factors contributing to it
A
- young age
- nulliparity
- early menarche (prior to age 12)
- heavy menstrual flow
- tobacco smoking
- low fish consumption
- BMI above 30 or below 20
- PMS symptoms
- stress, anxiety, depression
13
Q
Secondary Dysmenorrhea
A
- mid to late 20s or older, usually 30s and 40s
- more likely irregular menses, menorrhagia or metrorrhagia is more common
- pattern and duration of pain can vary with cause these changes in pattern or intensity may indicate secondary disease
- There may be pain during other parts of the menstrual cycle
- NSAIDS don’t really help
14
Q
Primary Dysmenorrhea symptoms
A
fatigue, headache, nausea, change in appetite, backache, dizziness, irritability, depression
15
Q
Secondary Dysmenorrhea symptoms
A
vary according to cause but may include dyspareunia (genital pain) and pelvic tenderness
16
Q
Ovulation
A
each month, an egg matures in the ovaries and is released through the fallopian tube into the uterus
17
Q
Implantation
A
- if the egg is fertilized by the sperm, it implants on the wall of the uterus
- Leads to pregnancy
18
Q
Egg is not fertilized
A
- it then exits the body through the cervix and vagina
- Leads to menstruation
19
Q
Menstruation
A
- Hormone levels drop and the endometrium (uterine lining) breaks down
20
Q
Primary Dysmenorrhea Exclusions for Self-Care

- most effective when taken on schedule
22
Q
Using Acetaminophen for dysmenorrhea
A

25
PMS
Premenstrual Syndrome
26
PMS Pathiophysiology
- fluctuations in estrogen and progesterone caused by normal ovarian function are the cyclic triggers for symptoms

Lower beta- endorphin levels
lower tolerance for discomfort and pain
28
PMS symptoms

32
Premenstrual dysphoric disorder (PMDD)
five or more symptoms, physical or mood, that are present the last week of the luteal phase with at least one symptom being significant depression, anxiety, affective lability or anger. Severity of symptoms interfere with work, school, social activities and social relationships. Symptoms should be absent the week after menses and must not be an exacerbation of another disorder like panic disorder

- explain that EC does not protect against STIs and is not 100%
62
Vaginal Canal
Acidic (4-4.5 pH) - prevents infections but acidity decreases with age
- colonized by many organisms but the most common is lactobacillus
63
Acidity and Colonization impacted by
1. hormonal fluctuations
2. drug therapy
3. Douching/feminine hygiene deodorant products
4. number of sex partners
64
Bacterial vaginosis
33% of vaginal symptoms, generally in younger and sexually active females
- No OTC treatment
65
Bacterial vaginosis (BV) Symptoms
- Thin, watery, off-white or discolored sometimes foamy discharge
- unpleasant fishy odor
- odor may increase after intercourse or menses
66
BV differentiating signs
Vaginal Irritation, dysuria, itching occur LESS frequently with BV than VVC or trichomoniasis, higher level of discharge than in VVC, foul odor is so common that lack of odor rules out this infections
67
BV Causes (Etiology)
polymicrobial infection, results from imbalance in normal vaginal flora with increased Gardnerella vaginalis and anaerobic bacteria species
Risk Factors:
- new partners
- african american race
- IUDs
- douching
- receptive oral sex
- tobacco use
- prior pregnancy
68
Trichomoniasis
- 15-20% of vaginal infections
- STI
- No OTC treatment
69
Trichomoniasis symptoms
copious, malodorous, yellow-green, frothy discharge, dysuria, no symptoms initially in 50% of affected women, men may be reservoirs asymptomatically
70
Trichomoniasis differentiating symptoms
- Erythema( reddening of skin) and vulvar edema( swelling of tissue) can occur, yellow discharge
- greater likelihood it is trichomoniasis over BV or VVC
71
Trichomoniasis risk factors
- STI caused by Trichomoniasis vaginalis
- multiple sex partners
- new partners
- nonuse of barrier contraceptives
- presence of other STIs
72
Vulvovaginal candidiasis (VVC)
- 20-25% of vaginal infections
- no identifiable cause for most infections
- OTC treatments available
73
VVC symptoms
- thick white "cottage cheese" discharge
- no odor to discharge
- normal pH
74
VVC differentiating symptoms
- Presence of erythema
- itching and/or vulvar edema AND absence of malodor ( unpleasant smell) increase likelihood
- thick "cheesy" discharge is a classic predictive sign
75
VVC Causes (Etiology)
- Cause by yeast fungal
- Caused by Candida albicans
- Candida glabrata
- Candida tropicalis and Saccharomyces
76
VVC risk factors
- antibiotic use
- immune suppressant use
- possibly pregnancy
- possible during and after menopause
- onset of regular sexual activity
- receptive oral sex
77
VVC Diagnosis
- no alteration of vaginal pH
- must wait 72 hours to test if contraceptive spermicide or antifungal product use
- must wait 48 hours after sex/douching
- wait 5 days after a period
- if pH is more than 4.5
it's less likely to be VVC
78
VVC Treatment
- Selt-treatment can be done if: symptoms are infrequent ( no more than 3 in the last year or 1 in the last 2 months
- a medical professional diagnosed at least 1 previous episode of VVC
- current symptoms are mild-moderate and consistent w the characteristics signs and symptoms of VVC
- if pH is 4.5 or lower
79
VVC exclusions to self care
- Pregnancy
- girls <12 years old
- concurrent symptoms: fever or pain in lower abdomen, back or shoulder
- Medications that can predispose to VVC: corticosteroids, anti-cancer meds
- Medical disorders that can predispose to VC DM, HIV
Recurrent VVC: more than 3 infections a year or infection in the past 2 months
80
VVC Pharmacological options
Butoconazole, clotrimazole, miconazole, tioconazole are all equally effective (80-90%),
- adverse reactions: vulvovaginal burning, itching, irritation (3-7%)
- best if used at nighttime to avoid leakage
- creams may be applied to vulva for itching in addition to any of the internal options
- symptomatic relief may occur within 2-3 days but complete resolution may take longer
81
Butoconazole dosing
2% cream: insert vaginally for a single dose
82
Clotrimazole dosing
- 1 % cream: insert vaginally for 7 days, apply to vulva 2x daily for itching
- 100mg tablet: insert tablet vaginally for 7 days
- 2% cream: insert vaginally for 3 days
83

- 200mg suppository: insert vaginally for 3 days
- 100mg suppository: insert vaginally for 7 days
84
Tioconazole dosing
6.5% ointment: insert vaginally for a single dose
85
VVC counseling points
- safe and effective to use during menstruation - you can wait until period is done to treat
- avoid tampons and douching use for 3 days after
- refrain from sexual intercourse, use of latex condoms or spermicides during and 3 days after
- a sanitary pad or panty liner is recommended to avoid underwear staining

- Boric Acid: 600mg capsule 1-2x daily for 2 weeks
87
VVC special populations
- under 12: refer, may indicate sexual abuse
- pregnancy: self-care not appropriate, if MD indicates OTC use clotrimazole or miconazole
- safe for breastfeeding and elderly
88
