Hypogonadism - Diurnal Variation
Testosterone levels best checked in *AM when Testosterone is highest* Explains AM erection phenomenon Diurnal rhythm lost in poor sleepers, nightshift workers, so on
menstrual cycle side notes
The corpus luteum will undergo spontaneous regression starting 9-11 days after ovulation unless "rescued" by hCG produced by an implanting trophoblast. Involution of the corpus luteum is accompanied by dramatic fall in the production of estrogen, progesterone, and inhibin. This removes the negative feedback suppression of the hypothalamus followed by an increase in GnRH pulse frequency. Because inhibin selectively inhibits FSH release to a greater extent than LH, the decline in inhibin production leads to a greater release of FSH than LH just prior to menstruation. This selective rise in FSH allows a new cohort of follicles to escape atresia and initiates the selection of a new dominant follicle.
what does the fall in progesterone cause
The fall in progesterone destabilizes lysosomal membranes resulting in the release of potent lytic enzymes in the endometrium which bring about the release of prostaglandins and endometrial autolysis. The release of prostaglandin F2a induces rhythmic vasodilation and vasoconstriction of the spiral arteries leading to endometrial ischemia, vascular thrombosis, and myometrial contractions (experienced clinically as menstrual cramps).

hormones of ovulatory cycle
FSH causes 2ry follicles (antral) to develop and proliferate and make estrogen once a Graafian follicle is chosen - alot of LH is released IGF-1 is also needed in the process - binds to insulin like receptors
explanation of glucose and insulin levels during pregnancy
Fasting glucose levels decrease because glucose is transported across the placenta to the fetus by facilitated diffusion, and amino acids actively transported to the fetus are not available for maternal gluconeogenesis. Lipolysis and ketogenesis increase, and fasting ketone and free fatty acid levels are higher. Fatty acids do not cross the placenta. Maternal insulin is bound and degraded by the placenta and does not cross into the fetal compartment. The fetus depends on its own insulin for glucose disposal; fetal insulin is produced by 12 weeks gestation.
when to do fetal testing for Rh
Fetal testing if father is heterozygous or unknown do amniocentesis or Chorionic villus sampling (CVS): Amnio preferred due to less FMH, avoid transplacental passage Fetal blood sampling: consider if amnio negative yet titers rise Cell-free fetal DNA: widely used in UK and Europe - testing the mom's blood

cytology vs biopsy
Surface cells have higher nuclear/cytoplasmic ratio in severe dysplasia than in mild dysplasia. This difference is relied upon in Pap smear evaluation. Pap smear finding of high grade SIL (Squamous Intraepithelial lesion) usually correlates with biopsy finding of CIN III. However, there are cases in which there is a lack of correlation between cytology and biopsy findings. A biopsy is therefore usually done in managing patients with low grade or high grade SIL.
treatment for ovarian surface epithelial tumors (carcinomas)
Surgery: Debulking and Staging (TAH - total abdominal hysterectomy) TAH/BSO, pelvic and peritoneal biopsies, omentectomy, para-aortic and pelvic lymph node dissection for staging Aspiration of ascites, pelvic wash, biopsies from paracolic gutters, surface of diaphragm for staging Adjuvant Chemotherapy: Combination of a platinum compound (carboplatin/cisplatin) and a taxane (paclitaxel/docetaxel)

vaginal cytology after menopause
The vaginal surface becomes thinner, less elastic, and more friable. Fewer vaginal secretions are produced, and production is delayed longer during sexual stimulation *loss of rugal folds*. The most common symptoms of vaginal atrophy are *vaginal dryness, itching, and burning but may include dyspareunia and leukorrhea (yellow malodorous discharge).* Thinning of the mucosal lining of the urethra and bladder may result in urethritis accompanied by frequency, urgency, and dysuria
toxemia of pregnancy: events
There are events of primary importance in this disorder: 1) placental ischemia → 2) HTN → 3) DIC (disseminated intravascular coagulation) The causes of the initial events in toxemia are unknown, but evidence points out to an abnormality of placentation. This may involve both an abnormality in both trophoblast invasion and the development of the physiologic alteration in the maternal vessels required to perfuse the placenta adequately. This results in placental ischemia, the basis of the toxemic placenta.

how come, the dominant follicle has alot of FSH recptors yet makes the highest amount of estrogen? knowing that estrogen turns of the FSH produciton
during this part of the cycle, estrogen switches to positive feedback instead of negative feedback
what happens to the paramesonephric duct in females - in terms of migration and movement
each duct (one on each side) will come to the center and meet each other and touch on the urogenital sinus this induces the urogenital sinus to send a "bud" out into the parameso duct - hellps form the vagina

the epithelium is hormonally responsive so: - SLIGHT INCREASE IN SIZE AT END OF MENSTRUAL CYCLE OR DURING PREGNANCY - REGRESSION OCCURS POSTMENOPAUSALLY LEADING TO HYALINIZATION AND CALCIFICATION
what is hydrosalpinx
the fellopian tubes become filled with fluid, becomes almost like a cystic mass
when will an insult most likely result in a spontaneous abortion?
the first 3 weeks
what makes estrogen?
the follicles
when the oocyte come out of the ovary - what holds it to make sure it doesnt fall into the peritoneal cavity
the glycosaminoglycans - are basically like glue
golgi phase of spermiogenesis followed by the acrosomal phase
the golgi makes vesicles that begin to form the acrosome this part of the sperm will move to the anterior portion of the cell *the one that faces the sertoli cell* at this point the *centrioles move to the back; the flagella begins to grow there*
what are stage 0 breast cancers?
the in situ ones
in mediastinum, the sminiferous tubules connect to
the intratesticular ducts: - Straight tubules: epithelium is sertoli w/some cuboidal - Rete testis: cuboidal cells - Efferent ductules: *lined by alternating cells that have and dont have celia; connect to the epididymis; phygocytose a bad cells the sertoli made; have some smooth muscle and a SCALLOPED LOOK* at this point, the sperm arent even motile, they move by peristaltic movement and the fluid movement
how to tell you are on the chorionic plate?
the membrane is smooth on the maternal side it is irregular due to the invasion
during male gential development what part of developmental nephron systems is retained?
the mesonephric duct is retained (the caudal most excretory tubules that attach to the duct) in female it will degenerate
what does the uroteric bud make?
the metanephric kidney originally empties into the mesonephric duct
what is the decidua/what does it do
the mucous endometrium that undergoes changes during pregnancy keeps the embryo separated from the actual muscle of the uterus
wilms tumor is thought to arrise from
the nephrogenic zone (primitive kidney) sits under the renal capsule supposed to be gone by time of birth, children with NZ remnants seem to develop wilms tumor
pap with HPV infection
the nuclei get bigger with perinuclear clearing (called koilocytosis) aka LGSIL - low grade squamous intraepithelial lesions
most trisomys are derived from
the ovum, over 90% higher risk with higher age (specially women >40) bc it depends on the length of time the follicle stays arrested in meiosis I. Decades of dormancy thought to increase nondisjunction
DHT effects on genitalia
the phallus begins to grow urethral groove fuses/closes scrotal swelling become the scrotum
what happens when decidua is thin?
the placenta can attach to the muscle and wont let go during delivery
what does the placenta have that the embryo lacks in order to make estriol (E2)?
the placenta has sulfatase, to take out the sulfate on DHEA the embryo uses its adrenal cortex to make DHEA-sulfate and the liver to add and OH group.
most important histo factor for wilms tumor
the presence of anaplasia: tripolar mitotic figures and nuclear pleomorphism (nuclei 3x bigger than neighbors' and hyperchromatic)
in the 6th week (undefferentiated) what happens in the abscence of SRY (TDF), no MIF etc
the primitive sex cords degenerate instead of turning into the seminiferous tubules, epithelium doesnt thicken 2nd wave of chords come from the epithelium - the cortical sex chords which get showered by the primordial germ cells: form the follicle
what is DHT responsible for
the prostate gland AND the external genitalia
spermiation
the release of a spermatozoa by a sertoli cell
nonproliferative fibrocystic cysts in breast & metaplasia
the secretory products within the cysts can calcify: shows up on mammogram *apocrine metaplasia*: - cysts becomes lined by polygonal cells with abundant granular eosinophilic cytoplasm
what does paraxial mesoderm give rise to
the somaties sleratomes, dermatomes, myotomes
what part of the fetus invades the blood vessels
the synctyiotrophoblasts
what separates ovarian (serous/mucinous) borderline tumor from cysts?
the the epithelium for borderline is more than a single row of cells, grossly then look like a cystic wall with some outgrowths
umbilical cord vilamentous insertion
the umbilical cord can insert into the fetal membranes instead of the fetal surface of the placenta: - if the veins cross the cervix, can have vasa previa - the vessels are more prone to mechanical damage since they arent really protected
IVF and maternal age
the younger the more viable, like regular pregnancy
what layer surrounds the basal membrane of a primary oocyte?
theca cells
mature corpus luteum histo
thecal cells become thecal leutin cells granulosa cells become granulosa leutin cells
effects of estrogen on the body
there are estrogen receptors almost everywhere in the body
what happens at the time of menopause follicle-wise
there are no follicles left
what always happens in twin gestation? vascular wise
there is always anastamosis between the two placental disks The presence of vascular anastomoses is the anatomic basis for twin to twin transfusion - when one baby has too much blood, the other not enough
annovulatory cycle simply
there is no ovulation -> no corpus leuteum -> no production of progesterone so only constant estrogen affecting the EM -> growth until it outgrows its blood supply and bleeds
characteristic complaint of a patient with Kallman's syndrome
they can't smell anything
what do granulosa cells do when body switches to more LH secretion than FSH?
they continue to produce estrogen, but now under the control of the steroid made by the theca interna
what happens during the process of development between the sperm?
they form cytoplasmic bridges so they are talking to each other while they develop
what do cytotrophoblasts do
they migrate all the way across the endometrium and form a layer next the maternal decidual cells is the layer that holds the embryo to the uterus - called the basal plate also remodels the blood vessels
problem with tamoxifen and roloxifen?
they still have the thrombotic effects that we try to avoid from estrogen
SRY leads to
thickening of epithelium around the genital ridge becoming - tunica albuginea primary cords detach from the epithelium (inside) and get populated by primordial germ cells - where the seminiferous tubules will form differentiation of sertoli and leydig cells
complications of prostate nodular hyperplasia
thickening of the muscle of bladder UTI's hydronephritis bladder diverticuli
giving a pt prostaglandin E1
this drug it doesnt matter what you are doing, even if spinal cord isnt working if given to the penis tissue it should relax and SM and allow an erection
where does testicular cancer metastasis go?
to where the testes came from, goes to the posterior abdomen
Surface inclusion cysts are formed by
trapped ovarian surface epithelium and play important role in the pathogenesis of ovarian cancer
Wilm's tumor histo
triphasic tumor 1) small round blue cell component: blastema 2)epithelial component-immature tubules (most often) and glomeruli 3)mesenchymal stromal component
what happens to the endometrium if there is implantation
trophoblasts in the ovary differentiate to make syncytiotrophoblast and cytotrophoblast lacuna get invaded, glands get invaded
what glands make milk
tubualveolar glands, drain into the lobules that lead to the lactiferous ducts
what carcinoma has apocrine snouts? what are they?
tubular carcinomas are small projections into the lumen of the cytoplasm
spermatogonia are inside a _____
tubule surrounded *loose connective tissue w/ many fibroblasts* as we get close to basal lamina fibroblasts assume properties of *smooth muscle cells: called myoid cells* on top of basal lamina - stratified epithelium sometimes called a *germinal epithelium* lying right on the basal lamina is the spermatogonia (adluminal compartment): turn to spermatocytes as they move towards the lumen
colloid carcinoma (mucionous carcinoma) of the breast
tumor cells "float" in white mucinous material older women, slow growing well circumscribed and soft excellent prognosis associated with hypermethylation of BRCA1 promoter in 55% of cases
Leiomyomas (macroscopic and microscopic)
tumor is well circumscribed composed of smooth muscle and connective tissue (sometimes the smooth muscle gets replaced by fibroblasts: *hyalinized leiommyomas*) *cigar shaped nuclei*
acute endometritis (inflammation0
uncommon, its usually combined with chronic endometritis Vaginal discharge, infertility, uterine tenderness, asymptomatic most commonly due to Retained placental tissue (Post-abortion / partum) can be due to an ascending infection from vagina Tx: Removal of retained tissue, antibiotics
non-invasive ways to assess hemolytic anemia of the baby?
use doppler ultrasound anemic babies will try to move the blood faster and therefore will show more flow in the doppler
applications of cytopathology
used to screen for the early detection of asymptomatic cancer, including organs such as the uterine cervix (the pap smear), bladder (urine cytology), lung (sputum cytology), and endometrium (endometrial brushings). for surveillance to detect recurrent cancer diagnosis of benign neoplasms, cysts, inflammatory conditions and infections
trisomy 13 and 18
usually not compatible with post natal life cleft lip and palate, clubbing, plydactyl, microopthamia
what happens to chromosomally abnormal embryos
usually they miscarry
what do E1 and E2 do in HPV?
usually they repress E6/7 when the virus integrates into the genome, E1/2 are lost in the process causing increased E 6/7
endometroid adenocarcinoma histo
very crowded glands see *cribriform glands*= small glands inside the bigger glands cannot trace individual glands *invasion of smooth muscle* of the endometrium
what do we use to stimulate eggs before IVF
we use gonadotropins to stimulate eggs to mature basically put a year worth of maturation into 1 cycle
Luteal Placental Shift During Pregnancy
when the corpus luteum stops making progesterone and the placenta takes over
Premature Ovarian Insufficiency
when the ovary no longer functions Chromosomal abnormalities Genetic (FMR-1) high FSH and LH Early oocyte depletion - severe infection, chemo, RT, or idiopathic
bone and estrogen
when there is no estrogen, there is more osteoclast activity
where in the cervix are most cases of squamous metaplasia
whenre endocervix meets the ectocervix (columnar to stratified squamous)
what part of the cervix is more prone to cervical dysplasia/cancer?
where it turns from columnar epithelium to stratified squamous
adluminal compartment
where the sperm lies not including the spermatogonia
GPR54 (KISS 1R)
which encodes a G-protein coupled receptor, appears to have an important role in the *initiation of puberty* via its effect on hypothalamic GnRH
explanation of enlargement/dysplasia/invasion
with HPV infection: see the koilocytes, basal cells ok dysplasia: basal cells become abnormal, some large some small invasion: going into stroma, dysplasia not a necessary precursor
why do they get hot flashes?
without estrogen the *thermoneutral zone* narrows so at lower temperature they begin to sweat and they might start shivering at a higher temperature as before
what would you find in SQCC of the lung when doing a Respiratory Tract smear: Sputum, Washings or Brushings
would find cells with pink cytoplasm - meaning squamous cells secreting keratin and therfore concluding that it is SQCC
are there genetic factore for the decrease in estrogen sensitivity of the hypo?
yes, proven by: Monozygotic twins-2.2mo between menses, Dizygotic twins-8.2 mo between also geographic area, stress, and body fat have a role
atretic follicle histo
zona becomes a solid pink band (bc its hard to digest)

■Male factor— 26 percent ■Ovulatory dysfunction — 21 percent ■Tubal damage — 14 percent ■Endometriosis — 6 percent ■Coital problems — 6 percent ■Cervical factor — 3 percent ■Uterine + Unexplained — 28
CARCINOMA IN MALE BREAST
♦ 1:100 ♦ strongly associated with brca2 in some families but not brca1 ♦ dcis and lcis are rare (so in situ is rare) ♦ same subtypes as female, more likely to have estrogen receptors ♦ due to scant amount of breast tissue rapidly infiltrates skin and thoracic wall ♦ men present at higher stages but when matched for stage prognosis is similar
ER, PR AND HER-2-NEU in breast cancer
♦ 2/3 of breast cancers are er+ or er/pr+. er+/pr+ have better prognosis. ♦ her-2-neu proto oncogene overexpression correlates with poor prognosis. overexpressed in 20-30% of breast cancer. human epidermal growth factor receptor
breast cancer clinical findings
♦ can cause retraction and dimpling of skin ♦ lymphatic involvement can cause lymphedema and skin thickening = peau d'orange ♦ involvement of lymphatics with redness and tenderness = inflammatory carcinoma, associated with high incidence of systemic metastases
male breast problems
♦ gynecomastia ♦ relative increase in adrenal estrogens ♦ cirrhosis of liver, drugs, alcohol, marijuana, heroin, anabolic steroids ♦ subareolar enlargement ♦ hyperplasia of the ductal lining with proliferation of hyaline collagenous connective tissue
breast cancer prognostic factors
♦ lymph node metastases: most important prognostic factor ♦ tumor size ♦ histologic subtype: tubular and colloid have best prognosis ♦ lymphovascular invasion ♦ tumor grade ♦ estrogen and progesterone receptors (bc we can just block the receptors) ♦ her-2-neu
spread of breast cancer
♦ spread by lymphohematogenous route ♦ outer quadrants = axillary nodes ♦ inner quadrants = internal mammary nodes ♦ supraclavicular ♦ 1/3 have metastasis at presentation ♦ distant metastases: lungs, bone, liver, adrenal, brain, meninges
