Gynecology - GU disorders + STIs Flashcards
PID will often present after
a period - blood is a good culture medium
always do cervical motion tenderness as a
1 handed exam! DO NOT put nondominant hand on abdomen when doing it!
Herpes crossing midline - is this primary or secondary infection?
Primary
Herpes DOES not cross midline in recurrences - if it does, suggests primary infection
Labial fusion
Assoc w/ excess androgens
- usually result of exogenous androgen exposure
Most common enzyme deficiency = 21 hydroxylase deficiency —> CAH
Tx = reconstructive surgery
Tx 21 hydroxylase d/o
Exogenous cortisol
Will feedback to decrease ACTH to decrease adrenal gland hormone secretion
Imperforate hymen
Central portion epithelial cells of hymenal membrane fail to degenerate and form hymenal ring
Usually dx at puberty in adolescents who p/w primary amenorrhea and cyclic pelvic pain.
Tx
- surgery to excise the extra tissue, evacuate any obstructed material, and create a normal sized vaginal opening
Transverse vaginal septum
Usually at lower 2/3 of vagina
Failure of mullerian tubercle to be cannalized
P/w primary amenorrhea and cyclical pain
Normal external genitalia
Vagina ends in blind pouch 2/2 septum
Tx = surgery
Vaginal atresia
- lower vagina fails to develop and is replaced by fibrous tissue.
- ovaries, uterus, cervix, and upper vagina are all normal.
- usually happens when urogenital sinus fails to contribute
the lower portion of the vagina - presents during adolescence with primary amenorrhea and cyclic pelvic pain.
PE
- absence of introitus
- presence of vaginal dimple
MRI/US can show large hematocolpos
Confirm nl upper repro tract
Tx
- surgery
- incise fibrous tissue and dissect until nl upper vagina ID’d
- the normal upper vaginal mucosa is then brought down to the introitus and sutured to the hymenal ring
Vaginal agenesis
aka Mayer-Rokitansky-Kuster-Hauser syndrome
Congenital absence of vagina
+
absence/hypoplasia of all or part of the cervix, uterus, and fallopian tubes
Features:
- nl external genitalia
- nl secondary sexual characteristics (breast development, axillary, and pubic hair),
- bl ovarian function.
- phenotypically and genotypically female
Usually present in adolescence with primary amenorrhea.
Tx:
- nonsurgical - create vagina using serial vaginal dilators pessed into perineal body (4mo - several yrs)
- surgery to create neovagina
Fertility
- after surgery, sex is ok
- pt can’t carry preggers - can harvest eggs for gestational surrogate though
Lichen sclerosis of vulva
Inflammatory dermatosis
Symmetric white, thinned skin on labia, perineum adn perianal region
- shrinkage and agglutination of labia minora
Usually in postmenopausal women
3-4% Inc risk vulvar cancer
Sx:
- pruritus
- dyspareunia
- usually no sx
Dx:
- always get bx to r/o vulvar SCC
Tx:
- high potency topical steroids (clobetasol or halobetasol)
Lichen planus of vulva
Multiple shiny, flat, red-purple papules usually on inner aspects of labia minora
- often erosive
Assoc w/ vaginal adhesions and erosive vaginitis
Usually in 50s-60s
Same as lichen sclerosis 3-4% inc risk of cancer
Sx:
- puruitus with mild inflammation –> severe erosions
Tx:
- high potency topical steroids (clobetasol or halobetasol)
Lichen simplex chronicus of vulva
thickened skin w/ accentuated skin markings and exocriations 2/2 chronic itching and scratching
Itching 2/2 many conditions (atopic dermatits, psoriasis, etc)
Tx:
- medium to high potency topical steroid
When do you bx benign lesions of vulva presenting with vulvar itching, irritation, burning?
Ulceration
Unifocal lesions
Uncertain suspicion of lichen sclerosis
Lesions or sx persisting after tx
Use colposcope!
1 tumor found on vulva
Epidermal inclusion cysts
- 2/2 blocked pilosebaceous duct or blocked hair follicle
Fox fordyce disease
Chronic pruritic papular eruption that localizes to areas where apocrine glands are found
Hidradenitis suppurativa
Skin dz most commonly affecting areas of apocrine sweat glands or sebaceous glands
Infected areas –> form multiple abscesses –> need I&D
Where are skene’s glands?
next to urethra meatus
Suspected bartholin’s dcut cyst - what do you do?
If > 40 yo, need to do bx to rule out rare Bartholin’s gland carcinoma
Usually self resolving
If cyst is large, can lead to abscesses and need I&D or word catheter placement
Marsupialization for recurrent duct cysts/abscesses
Warm sitz baths recommended
Gartner’s duct cysts
remnants of mesonephric ducts of wolfiann system
usually in upper part of vagina
DES exposure in utero…resulting risks?
Cervical lesions (cervical hoods, cervical collars, cervical hypoplasia, etc)
Cervical insufficiency in preggers
Clear cell adenocarcionma of cervix
Most cervical cysts are
Dilated retention cysts called nabothian cysts
Caused by intermittent blockage of endocervical gland
Usually no sx
Origins of reproductive structures
All arise from mullerian system except ovaries (from genital ridge) and lower 1/3 of vagina (from urogenital diaphragm)
Many uterine abnormalities can be associated with
Inguinal hernias
Urinary tract anomalies
Uterine septae vs bicorunate uterus in preggers
Uterine septae
- usually suffer from recurrent 1st trimester loss as septae is not vascularized so placenta can’t implant
Bicornuate uterus
- second trimester pregnancy loss, malpresentation, preterm labor and delivery
Uterine leiomyoma
Benign proliferations of smooth muscle cells of myometrium
Usually happen in women of childbearing age
Regress during menopause
Hormonally response to estrogen and progesterone
Classification of leiomyomas
Characteristics
Submucosal (beneath endometrium)
- usually assoc w/ heavy or prolonged bleeding
Intramural (in muscular wall of uterus)
- most common
Subserosal (beneath uterine serosa)
Fibroids vs adenomyosis
Fibroids have pseudocapsule
- compressed areolar tissue + smooth muscle cells
- little blood vessels
- as fibroids enlarge, can outgrow blood supply, infarct, and degenerate, causing pain
Adenomyosis tends to be more diffusely organized in myometrium
MRI to distinguish between the two!
Ways to dx fibroids?
Pelvic US
Can also use HSG, saline infusion sonogram, and hysteroscopy for location and size of uterine fibroids
- good for submucosal ones
Medical therapies for Uterine Leiomyomas
GO PAN AM
GnRH agonists (leuprolide, nafarelin) OCPs
Progestins (mirena IUD, medroxyprogesterone)
Antifibrinolytics (tranexamic acid)
NSAIDs
Androgenic steroids (danazol) Mifepristone
Indications for surgical intervention for uterine leiomyomas
Abnl uterine bleeding —–> anemia
Severe pelvic pain or secondary amenorrhea
Uterine size > 12 wk obscuring eval of adnexa
Urinary freq, retention, hydronephrosis
Growth after menopause
Recurrent miscarriage or infertility
Rapid increase in size
Tx:
- uterine artery embolization (not for those wanting more fertility and large and pedunculated fibroids)
- MRI-guided high intensity ultrasound (premenopausal, done with kids)
- myomectomy (want fertility)
- hysterectomy
Endometrial polyps
Benign overgrowths of endometrial glands and stroma over vascular core
Usually in 40s-50s
Tamoxifen women at risk
Present w/ abnl vaginal bleeding
Eval w/ US, sonohysterogram, hysteroscopy
Tx - can be malignant or premalignant so remove in all postmenopausal; premenopausal remove too
Endometrial hyperplasia
Source of abnl uterine bleeding
Abnl prolif of both glandular adn stromal elements of endometrium
Can happen when endometrium exposed to continuous estrogen w/o progesterone
Risk endometrial carcionma
Dx:
- bx in office
- D&C
Risks for endometrial hyperplasia
Unexposed estrogen exposure
Obesity Nulliparity Late menopause exogenous estrogen w/o progesterone Tamoxifen use HTN DM Lynch II syndrome
Tx endometrial hyperplasia
Simple + complex atypia
- progestin therapy (depoprovera or provera)
- repeat EMB for regression
Atypical hyperplasia
- D&C eval
- hysterectomy if no kids in future
- if want kids, progestin management, repeat EMB at 3 months —–> if persistence after 9 months, hysterectomy recs
Functional cysts of the ovaries
Follicular (most common)
Corpus luteum
Follicular cysts of ovary
Most common
Happen after failure of follicle to rupture during follicular maturation phase of menstrual cycle
Usually resolve spontaneously in 2-3 months
Simple cysts < 2.5cm are physiologi
Corpus luteum cysts of ovary
Occur during luteal phase
Happen when corpus luteum fails to regress after 14d and becomes enlarged or hemorrhagic
Can rupture!
Theca lutein cysts of ovary
Large bilateral cysts filled w/ clear straw colored fluid
2/2 stim from abnormally high bhCG (eg molar preggers, choriocarcionma, ovulating induction)
Endometriomas
Ectopic endometrial tissue within ovary
Aka “chocolate cysts”
Endometriosis
1 dx in eval of infertility in couples
Endometrial tissue outside of the uterus
Sx:
cyclic pelvic pain beginning 1 or 2 weeks before menses, peaking 1 to 2 days before the onset of menses, and subsiding at the onset of menses or shortly thereafter.
