stress urinary incontinence
who is this common in?
why does it occur?
explain the pressure differences?
what actions might bring this on?
what are 3 things that could cause this in a person?
common problem in women of all ages and results from weakness or disruption in the pelvic floor muscles leading to poor support of the vesicourethral sphincters
usually: the i_ntraurethral pressure is greater than the intravesicular pressure_ which is called the urethral closure pressure
if i_ntra-abdominal pressure increases_ from things like coughing, laughing, or sneezing and the pressure isn’t equally distributed to the urethra then incontinence occurs
causes of decreased muscle tone: aging, child birth, surgical procedures
urge urinary incontinence
what does the pt feel?
what is this associated with?
what is the definition of this?
what are 2 contributing factors?
3 symptoms?
overactive, nocturia, urinary frequency, detrusor overactivity
loss of urine associated with strong desire to void URGENCY, often associated with overactive bladder
definition: urgency, frequency with or without incontinence in the absence of UTI or obvious pathology
Two contributing factors to overactive bladder:
- CNS and neural control of bladder sensation and emptying, ex: stroke, Parkinsons, MS
- smooth muscle of the bladder itself (myogenic)
incomplete emptying “overflow” urinary incontinence
what are 7 signs of this?
what are two causes?
what are 2 causes in women?
what are 2 causes in men?
intravesical pressure exceeds the maximal urethral pressure because of bladder distension
dribbling, weak urinary stream, frequency, and nocturia, hesitancy, frequency, nocturia, nocturnal enuresis (bedwetting), detrusor underactivity or bladder outlet obstruction
women causes: uterine prolapse, previous incontinence surgery
men: most common is enlarged prostate gland
what are the 3 PE tests you want to do with someone with urinary incontinence?
what are the 4 workup tests you would do?
PE:
- pelvic exam
- digital rectal exam (masses, prostate)
- neuro exam if sudden loss (think cauda equina)
Workup:
- urinalysis
- prostate specific antigen
- post void bladder scan
- urology consult
although urinary incontince tx is dependent on the type, what are 5 tx options you could consider?

what is one really key thing to remember about UTI and pregnant women?
associated with preterm birth, low birth weight, prenatal mortality
screen in 1st trimester with UC
admit them since dangerous with baby
always check urine culture if asymptomatic because the bacteria in the urine can cause the things under A, if + treat with abx
if they get 2+ positive tests with greater than 100,000 positive tests they they will be on suppressive abx for the remainder of the pregnancy
Complicated UTI

dysfunctional uterine bleeding
what is this?
who do you most commonly find it in?
what is the MC cause?
what are the two dx tests you always do on eat pt?
dx of exclusion where abnromal bleeding without pathologic cause has been ruled out in very young or perimenopausal woman
usually an issue with the hypothalmic-pituitary-ovarian hormaone axis
MC: shortly after menarche or during perimenopause because of increased anovulatory cycles (90%) since there is unopposed estrogen it leads to irregular, unpredictable sheeding/bleeding“think: when cycle changes”
DX:
Always run:
CBC and platelents
PREGNANCY TEST
consider: all other testing needed to rule everything else out!!
how do you tx dysfunctional uterine bleeding with acute bleeding or long term bleeding?
2
4
- MC: NSAIDS
Acute:
- oral progestins
- IV estrogen for life threatening bleeding
chronic:
- cycle with low dose COP, patch, or vaginal ring
- cycle with progestin

- endometrial ablation
what is the most common gynecological malignancy?
endometrial cancer
endometrial cancer
who is this most common in?
what is the most common sxs of this?
dependent on what?
explain the characteristics of the two types?
5
4
what are the 4 dx methods?
MC gynecological cancer
most postmenopausal 75%, 50-60 years old
estrogen dependent cancer
mc sxs, inappropriate uterine bleeding postmenopausal
type 1:
MC type
unopposed estrogens stimulate the endometrium
well differentiated
starts as hyperplasia
curable
type 2:
endometiral atrophy
undifferentiated
clear cell and papillary serous histology
mor agressive and found at later stage
DX:
1. entometrial bx
- transvaginal US >4mm
- hysterscopy with bx
- dilation and cutterage GOLD STANDARD but not more effective, and not therapeutic
what are the tx methods for endometrial cancer? 3
what has a protective effect?
- total hysterectomy
- radiotherapy and chemo at advanced stages
- reccurence is txed with high dose progestins
OCP have protective effect?
what are 6 RF for type 1 endometrial cancer?
- obesity-fat makes weak estrogen which are unopposed after menopause and causes cellular change in uterus
- metabolic syndrome
- diabetes
- polycystic ovarian syndrome
- exogenous unopposed estrogen
- tamoxifen (breast cancer med)
explain the progession of type 1 endometrial cancer? explain the interventions throughout the process
- high weight + unoppposed estrogen+low exercise +low isofalvones leads to unhealthy endometrium
- unhealthy endometrium leads to endometrial hyperplasia (overgrowth of endometrial cells, premalignant and presents with heavy periods)
***intervene here with diet, exercise, weight loss program, hormone therapy
- if no intervention leads to endometrial hyperplasia with atypical cells
**intereven here with hormone therapy and surgery**
- if not intervention wil leads to endometrial adenocarcinoma which is CANCER!!!
explain tx options in:
- endometrial hyperplasia without atypical cells
- endometrial hyperplasia with atpical cells
- endometrial adenocarcinoma
- endometrial hyperplasia without atypical cells: diet, exercise, weight loss program, hormone therapy (progestin pO or mirena so estrogen isn’t unopposed and limits endometrial growth)
- endometrial hyperplasia with atypical cells: hormone therapy and surgery to remove effected areas

painful menstruation
primary
not due to pelvic pathology due to excess of prostaglandins and leukotrienes** leading to **painful uterine contractions, N/V/D
starts 1-2 years after the onset of menarche in teenagers
secondary
due to pelvic pathology so a identifiable condition
25 years and older
endometriosis, adenomyosis, uterine fibroids, PID, IUD
dysmenorrhea

what are the tx options for both?
sxs
primary:
- cramping, bloating, and lower abdominal pain that radiates to the back or thighs
- begins before or during menses for 1-3 days
secondary:
the above PLUS
- bloating
- mennorrhagia/dyspareunia
tx:

what must be present?
what percentage of women get this?
what two tests shoudl you do?
what are the 5 tx options?
cluster of physical, behavioral, mood changes with cyclical occurence during luteal phase of the menstrual cycle
occurs 1-2 weeks prior to mentstraion and ends 1-2 days after the onset of sxs
a symptom free period during the follicular phase, day 1 of menses must exist
75% of women have some symtpms of this
5% have severe sxs and distress that limit their ability to participate in lfe basically
DX:
thryoid to rule out thyroid issues
CBC to rule out anemia
Tx:
1. limit caffine, alcohol, sodium
2. frequent high-complex carb meals

3
3
cessation of menses after 1 year loss of ovarian activity at approximately 51

vaso motor sxs from decreased estrogen production
1. HOT FLASHES upper body, face, chest, and neck
- interfere with sleep
- 75% have them
- last 6 months -2 years depends on person

-can lead to dyspareunia and sexual dysfunction making a low quality of life, self-esteem, and sexual intimacy
3. sleep distrubances
4. new onset depression
menopause
what are the 3 tx options?
- systemic hormone therapy most effective estrogen or progesterone with the lowest effective dose and shortest duration but limited to 5 years or less of use
- SSRIs 2nd
- SNRIs
what must you consider when txing women for menopause with hormone replacement therapy?
use progesterone and estrogen as hormone therapy for this
must consider if woman has uterus or not BEFORE giving hormone therapy
- if no uterus: can use esterogen alone
this is the most effective tx, however, it increases the risk for endometrial cancer so you ONLY use it patients WITHOUT a uterus
- if uterus: must use estrogen AND progesterone
NO icnreased risk for endometrial cancer so can be used in patients with a uterus slightly increases risk for breast cancer so must keep this in mind
how do you dx menopause in woman? what if you wanted to check labs? what are they at increased risk for?
typically a clincial dx
in labs you would use FSH to dx because this would be high as well as LH while the estrogen levels are still low
they are at increased risk for osteoporosis so may want to consider putting them on medicalion to prevent this

anywhere from 15 mins to 2 hours
explain how hormonal contraception works? 3
1. inhibits secretion of pituitary gonadotropins via NEGATIVE feedback mechanism which prevent follicular follicle development and ovulation
2. alters endometirum (thinning) which may effect implantation by producing unfavorable environment for fertilization
3. thickens cerivcal mucous which inhibits sperm passage/penetration
what are the two most common emergency contraception options?
- levonorgestrel OTC (so convient) “plan B” 50-94% efficacy
- ulipristal Rx “Ella” 98-99% effective **MOST EFFECTIVE oral**
- paraguard *MOST EFFECTIVE METHOD*
how many menstrual cyles does a woman experience on average in her lifetime
about 400
explain the link between estrogen and breast cancer?
nullparity (not having children) increases the risk for breast cancer because it increases the number of menses the woman has thus increasing the amount of unopposed estrogen she is exposed to
this stimulation of cell proliferation during every cycle increases the risk for development of breast cancer
those who have early menarch and late menopause are also at increased risk because it increases the number of menses they have and ultimately exposes them to more estrogen
first pregnancy appears to have a protective effect
COOL FACT: THIS IS WHY NUNS HAVE A HIGH RISK FOR BREAST CANCER!!!
Why is it important that GnRH is released in pulses rather than continuously?
Pulsatile release: maintains normal FSH, LH levels in the blood
as GnRH is released it binds to gonadotrophs and causes released of STORED LH and FSH
**allowing a period of rest between pulses allows the gonadotroph to increase stores aka priiming effect**
continuous release: results in a REDUCTION of the pituitary contens of FSH and LH and their release (since trying to replenish stores)
clinical implications
GnRH agonists and antagonists: down regulate LH and FSH release since it continiously sitmulates receptors and doesn’t allow for the gonadotrophs to replemsih stores
these can be used in certain cancers to lmit the amount of estrogen/progesterone they are exposed to since this is the ultimate product of this process.
**may cause an intial flare in sxs and then down regulate**
- breast cancer
- endometriosis
- prostatic cancer
what are seroids made from? explain their carbon and conversion properities?
steroids are made from cholesterol which comes from acetate
progesterones: 21 carbons
androgens: 19 carbons
estrogens: 18 carbons
converstion of one steroid to another can be accomplished by enzymes that are a part of the cells biosynthetic package where carbons can be taken away but NOT added
aka a progesterone can become an estrogen but an estrogen can’t become a progesterone
what are most steroids produced from?
most likely acetate with the intermediate as cholesterol, however, direct synethesis also occurs with cholesterol that is produced by the liver or supplied by the diet
what is the first step of ALL steroid synthesis? what is this catalyzed by? explain the feedback between this and HMG coA reductase?
FRIST STEP: converstion of cholesterol to pregnenolone “MOTHER OF ALL STEROIDS” since all steroids stem rom this and process which occurs in the mitochondria of ther steroid producinc cell
this process is cataliyzed by mitochondrial cytochrome P450 side chain cleaving also referred to as desmolase 20-22
cholesterol is a negative feedback regulator of HMG CoA reductase….so when cholesterol is high this enzyme decreases, when cholesterol is low this enzyme increases
***THINK ABOUT IT: this is why HMG CoA reductase inhibits work for someone with high cholesterol, it prevents further synthesis!***
explain the solubility of steroids? what consequences does this have? 3 options? explain the difference in affinities?
structually similar to cholesterol since that is what they are derived from so they are
highly fat soluble and poorly water soluable….this means you find them bound to plasma proteins in the blood. MC albumin, sex steroid hormone, and cortisol binding globulin
albumin: low affinity for bound steroids, weak bond
sex hormone binding globulin (SHBG): high affinity for androgens (testosterone) and estrogens but low affinity for progestens and cortisol, strong bond
explain what is meant by bioavaliable steroid?
when you ask for a the lab to quantify the serum steroids it is a combination of BOTH ‘free” unbound steroids and bound steroids (how most are)
bioavaliable steroid referrs to both the bound and unbound steroid present
what is the free angrogen index?
meaures the amoutn of bioavaliable testosterone in a person
this can help to explain a pt who presents with hirsuitism or features suggesting androgen excess
explain the relationship between sex binding hormone globulin and testosterone levels between males and females?
the majority of steroids are bound with proteins in the blood. many are bound with albumin, but many are bound with sex hormone binding globulin (SHBG)
when bound with SHBG the steroid becomes inactivated.
In men, more percent of testosterone is bound to ALBUMIN and therefore dissociates quickly, where in women is bound to SHBG and therefore is inactivated!
This explains the higher andronization of males than females because the testosterone is more bioavaliable
do changes is steroid levels greatly effect the serume concentrations/steroid effects?
not usually…..the carrier proteins like abumin and sex hormon binding globulin are always in excess of steroids, so if there are massive increases they can accound for this and it will have little effect on the body
the problem arises when there isn’t enough binding proteins like ablumin or SHBG where the slight changes in hormones show their effects more readily and is seen in conditions like liver diseases
are sex steroids like progesterone, testosterone, and estrogen kept at high or low plasma levels? why?
very low (much lower than cholesterol) with binding proteins like albumin and sex hormone binding globulins
want to keep these low because they are like cholesterol and are lipid soluble, this means that they can readily enter the cell
if these were present in high concentrations in the plamsa, they could readily enter the cell and disrupt the membrane integrity!
this is why even small levels of plasma steroids are present in the bound protein form
where are steroid hormone receptors found? and what are they bound to? what happens once they are stimulated?
found intracellular in both the nucleus and the cytoplasm often bound to heat shock proteins, that when stimulated by a steroid disocciate and bind to non steroid ligands like Thyroid hormones or vitamins
once stimulated: they undergo conformational change that allows them to recognize hormone-resonse elements (HREs) in the DNA which then allows for protein transcription/production
where are most sex steroids produced? exception? role of target organs? what enzyme?
most sex steroid hormones (progesterone, estrogen, and testosterone)** are made in the **gonads** with the exception of a **pregnant female
however it has been made clear the target organs have the ability to** **participate in INTERCONVERSION of one steroid to another thus they can take a ciculating hormone and transform it enzymatically into another steroid to use LOCALLY via its biosynthetic package of enzymes
EX:
5alpha-reductase converts testosterone to 5alpha-dihydrotestosterone “DHT” which is stronger!
what is the clinical correlation between 5alpha-reducatase and DHT levels? what percent of tesosterone is involved in this?
5alpha reducatse converts testosterone to DHT which is a stronger vesion of testosterone
5-8 % of total testosterone is converted to this
5alpha-reductase inhibitors, AKA FINASTRIDE, PREVENT the conversion of testosterone to DHT which can support the development of benign prostatic hypertrophy so reducing this enzyme in men helps to shrink enlarged prostates, can also help with baldness since DHT also contributes to this
hypothalamo-pituitary-gonadal axis
what is the pathway for production of steroids? how are they released?
HYPOTHALAMUS: RELEASES GnRH
TRAVELS VIA HYPOPHYSEAL PORTAL VEINS TO
ANTERIOR PITUITARY RELEASE FSH AND LH
TRAVELS VIA BLOOD TO
THECAL/GRANULOSA CELLS RELEASE ESTROGEN, PROGESTERONE, TESTOSTERONE
keep in mind GnRH and FSH/LH released in CHICORDIAL PULSES!!
hypothalmic gonadotrophic releasing hormone
what is this?
where is it encoded?
why is it difficult to measure?
neurohormone
encoded on chromosome 8 on single gene
serum levels: difficult to obtain since its release is confined to the hypophyseal portal blood supply and it has a short halflife 2-4 mins
FSH/LH
what is anothe rname for these?
what are they made of?
which is cleared fast which is cleared slow?
“gonadotrophins” since they effect gonad steroid synthesis in BOTH sexes
both contain alpha (identical) and beta subunits (different)
gylcosylated with sugar
FSH is cleared more slowly since it has more carbohydrates and this explains why when looking at infertility you check this because it provides more of a picture while LH is cleared fast and only provides a snapshot
inhibins
activins
effect FSH release from anterior pituitary
inhibins: allows only one follicle to be selected as graafian
activin: allows for developement
why is it important to consider CNS injury/damage in infertility?
GnRH is considered the most important final common mediator of ovulation
because the hypothalmus is the first step in the
hypothalamo-pituitary-gonadal axis process to release GnRH
OVULATION is needed for PREGNANCY so must have these pieces working if you want to get pregnant!!
CNS can lead to infetility issues
follicular phase
what does this refer to?
when does it occur?
2 key points?
OVARY from first day of menses to ovulation ~10-16 days
Key points:
- new antra follicles are recruited to proliferate
- one of these will be selected as the graafian follicle
proliferative phase
where does this occur?
when does this occur?
what are the 2 main things that occur?
UTERUS from the first day of menses to ovulation
- the uterus is under the influence of increase estrogen and the stratum functionalis of the endometrium proliferates from 1-2 mm to 8-10 mm in thickness
- increase in estrogen promotes the formation of progesterone receptors in the uterus so it can respond to progesterone in the post ovulatory phase of the cycle
luteal phase
when/where does this occur?
what are the 2 things that occur?
OVARY after ovulation until onset of next menses (assuming pregnancy doesn’t occur
- corpus luteum (formerly graafian follicle) is functional unit of the luteal phase and produces increased levels of progesterone
- occurs 13-15 post ovulation
secretory phase
where does this occur?
when?
what is it marked by? goal?
if no implantation?
UTERUS after ovulation until next menses
- high levels of prosterone secreted from corpus luteum have a “quieting’ effect on the unterine endometrium and facilitate
- secretions from the uterine endometrial glands to make condusive for implantation of a blastocyst
- if no implantation: the corpus luteum dies and the endometrial tissue looses its blood supply since loss of progesterone production and causes necrosis of linging and sloughing!! MENSES and the begining of a new cycle
embryonic ovary
what is the final goal of this step?
explain the 4 phases of this developement?
- oogonia undergo MITOSIS for 3-4 months
- Enter meiosis I and are called OOCYTES
- they become arrested in PROPHASE of the first meiotic division
- start to be surrounded with PRE-granulosa cells and is termed
primordial follicle
folliculogensis
explain folliculogensis up until the formation of the graafian follicle?
explain gonadotropin dependent and indepent phases?
5 steps
- pulsatile LH and FSH released at puberty“awaken” the primordial follicles
- primoridial follicles become primary follicles with zona pellucida that serves as attachment for the granulosa cells
- primary follicles become secondary occytes or “pre-antral follicles” where the granulosa cells increase in size and the thecal layer forms
***up until this point the the development has occured INDEPENDENT OF GONADOTROPINS***
- LH and FSH increase in response to decreasing estrogen and progesterone from the previous cycle stimulating the pre-antral follicle to tern into a tertiary follicle
- one of these is selected as the graafian follicle
explain the postive and negative feedback cycles that are seen in the menstrual cycle?
low levels of estradiol 17 B feedback NEGATIVELY on FSH and LH release at both the level of both the pituitary and the hypothalamus in the early follicular phase and in the luteal phase
HOWEVER, in the late follicular phase very high plasma levels of estradiol 17 B promote a POSITIVE feedback on both the pituitary and hypothalamus which is necessary to facilitate the midcycle surge of FSH/LH just prior to ovulation
explain how hormonal contraception methods play into the negative and postivie feedback mechanisms of the menstrual cycle?
if you use low levels of estrogen “low estrogen pill” it is inhibitory on FSH and LH and so you never get the LH surge which prompts ovulation! this means the ooccyte is never released into the fallopian tube
also prevents the lining of the endometrium from proliferating since this also suppresses progesterone
explains what happens to the LH and FSH receptors during the mentrual cycle?
early to mid follicularp phase:
1. LH receptors are only found on the thecal cells (outer layer) of the dominant follicle
- FSH only found on granulosa cells
mid to late follilcular phase:
- LH receptos begin to appear along with FSH receptors on the granulosa cells of the selected follicle
******MAKES IT MORE RESPONSICE TO THE LH SURGE WHICH STIMULATES OVULATION AND THE DEVELOPMENT OF THE CORPUS LUTEUM POST OVULATION****
luteal phase summary
describe all the aspects of this
the increase from the LH surge “lutinizes” (give the ability to make progesterone to the corpus luteum through stimulation of the LH receptors on the thecal and granulosa cells
causes massive** **progesterone release and some estrogen which prepares the endometrium for implantation by quieting it and:
- increasing blood flow
- increasing nuitrient secretions
- decreasing contractions of uterus
massive release of progesterone and some estrogen inhibits the FSH and LH release via GnRH inhibition via NEGATIVE FEEDBACK
if no pregnancy the CL begins to die (Cl needs FSH to LH to live and you have suppressed it so much through negative feedback there isn’t enough to support it) and the plasma estrogen and progesterone decrease, causes NECROSIS OF ENDOMETRIAL LINING AND NECROSIS
starting the cycle over with the increase if estrogen and progsterone in follicular phase
explain what happens in the luteal phase if fertilization occurs?
the blastocyst implants on the endometrial wall and forms placental membranes that secrete human choronic gonadotropin
HCG has a very similar structure to LH so it can therefore rescue the corpus luteum by binding with LH receptors
this means the PROGESTERONE PRODUCTION CONTINUES UNTIL WEEK 9-10 WHERE THE STEROID SYNTHESIS SWTICHES OVER TO THE PLACENTA
aka luteal-placental transition period
explain the hormonal interaction seen in polycystic ovarian syndrome?
7 steps
explain how this factors into exposure to unopposed estrogen exposure?
caused by an abnormal hypothalamus-pituitary ovarian axis
1. increased LH realeased compared to FSH
2. increase androstenedione and testosterone by the thecal cells of the ovary
3. androstienedione is converted to estrogen in the tissues, and is a weak estrogen
4. this STIMULATES LH release and inhibits FSH release
5. the low levels of FSH prevent the follciles from fully developing and ovulation doesn’t occur
6. the androstienedione that accumulates from the LH binding to the thecal cells continues to increase the androgen present cause HIRSUITISM and ACNE
7.this is a viscious cycle that cause anovulation and also the cystic formation of the ovaries
***INSULIN PLAYS ROLE BECAUSE IT IS THOUGHT TO CONTRIBUTE TO HIGH ANDROGEN LEVELS AND MAKE THE SITUATION WORSE!!!****
this explains why they are at risk for unopposed estrogens because since there is no ovulation (or corpus luteum development) there is no increase in progesterone which leaves the estrogen unopposed and increased risk for endometrial cancer!

gestational diabetes
explain the pathophys of why this occurs?
- levels of diabetogenic placental steroid and peptic hormones rise linearly through 2nd and 3rd trimester
- lead to increase of glucose levels in blood
3. progressive increase in tissue resistance to maternal insulin, body dose this intentionally because if the mothers tissues are resistant to insulin, she won’t take up the glucose and it will pass through the placenta to nourish the baby, mechanism to make sure the fetus gets nuitrients
3. resistance leads to increase of insulin levels which doesn’t help because the tissues are resistant
4. insulin contributes to post prandial hyperglycemia since it isn’t functioning and can’t take up the sugar!!
5. when post prandial maternal glucose levels rise excessively it causes fetal hyperglycemia** (since it has all passed through placent to fetus) **and fetal hyperinsulinemia (since increases production to deal with massive glucose infux)
6.hyper insulinemia promotes storage excess (since the amount avalible from mom is almost never ending compared to volume of blood avaliable in baby)
7. increased nuitrients lead to macrosomia in baby (enlargement and delayed pulmonary maturation)
pelvic inflammatory disease
