repro and neonatal Flashcards
female repro anatomy
ovaries, oviducts, uterus, cervix, vagina
ovaries
Side of production of unfertilized, eggs, and many hormones
oviducts
eggs passed from the ovaries into the oviducts site of fertilization for the sperm
uterus
composed of left and right horn and uterine body where developing embryo is mature
male reproductive anatomy
testicles, vas deferens, prostate gland, and penis
testicles
sperm production and storage
prostate gland in vas deferens
The sperm is transported to the prostate gland by the vas deferens within the prostate additional fluids are added for transport
vaginitis
inflammation of the vagina
signalment for vaginitis
juvenile or puppy and adults
etiologies of vaginitis
poorly understood
clinical signs of vaginitis
minimal or no signs discharge of vulvar lips Commonly described
adult onset vaginitis is more common…
spayed dogs rather than intact dogs
common complaints associated with vaginitis
vulvar licking, pollakiuria, urinary incontinence
Dx of vaginitis
cytologic examination of vaginal epithelial cells and vaginal discharge, vaginal and urine bacterial cultures, UA, vaginoscopy
Tx vaginitis
depends on bacterial CandS (antibiotics if appropriate)
pseudopregnancy
false pregnancy
etiology of pseudopregnancy
decreasing levels of progesterone and increased levels of prolactin following estrus cycle
clinical signs of false pregnancy
weight gain, enlarged mammary glands, lactation, vaginal discharge, behavior changes, mother activity, restlessness, false labor
Tx false pregnancy
do not require treatment and will resolve in 14-21 days
pyometra
pus in uterus
etiology of pyometra
secondary infection as a result of hormonal changes in reproductive tract the second cystic lining secretes fluids that create an ideal environment for bacteria to grow in
bacteria causing pyometra
streptococcus, klebsiella, Pastorella, Proteus, Moraxella, staphylococcus
what happens if cervix is open or relaxed
bacteria normally found in vagina can enter uterus
signalment for pyometra
intact females, middle, aged to older
clinical signs of pyometra
if cervix is open, possible drain from uterus through vagina to the outside, if cervix is closed, pus will not be able to drain and abdominal distend
more clinical signs of pyometra
fever, abdominal, enlargement, vomiting, lethargy, PU/PD, dehydration, azotemia, vaginal discharge
Dx pyometra
history clinical signs, CBC, radiographs ultrasound
Tx for pyometra
Ovariohysterectomy
dystocia
difficult labor
etiology of dystocia
maternal factors: uterine inertia (lack of coordinated contractions or exhaustion of uterine musculature), narrowed birth canal
fetal factors: large fetuses, abnormal position
signalment for dystocia
any, brachycephalic dogs and siamese cats are predisposed
average gestation for dog and cat
roughly 63 days
stage 1 of labor
female often stops eating, becomes restless, may vomit, rectal temp drops, may find a corner and start making a bed
stage 2 of labor
female starts to contract uterus forcibly, start gradually and increase intensity frequency and duration
stage 3 of labor
expulsion of placenta
signs of distress in pregnant animal
goes beyond proposed due date, no evidence of stage 1, no fetus delivered after an hour of labor, vaginal discharge turns green or bloody, animal in pain, babies are stillborn, alive but seem weak or not normal
treatment for dystocia
animal should be examined for systemic illness, sterile digital vaginal exam to evaluate patency, rads and US, medical management should be considered, Sx might be necessary
clinical signs of vulvar and penile tumors
depend on location, may see mass protruding from vulva or sheath, perineal swelling, discharge, dysuria, constipation
TX for vulvar and penile tumors
Sx removal with OHE reduces in females, Sx removal and chemo maybe benefit male
canine transmissible venereal tumors (CTVT)
common tumor on dogs, multiple SQ nodules on external genitalia, lipsand other parts of body
etiology CTVT
transplant of cancer cells (59 chromosomes instead of 78), cell type is probably a histiocyte
signalment CTVT
any, but young dogs are more common
transmission of CTVT
direct contact (copulation, social behavior, sniffing, and licking) fomites, mechanical vectors
Dx CTVT
appearance: cauliflower like, pedunculated and nodular
Bx: definitive Dx
Tx CTVT
Sx removal with chemo or radiation
Px CTVT
good with appropriate Tx
