|
believed to be caused by the increase in lumbar lordosis and the relaxation of the ligaments supporting the joints of the pelvic girdle (as a result of hormones)
|
|
Infants born to patients with Graves disease treated with surgery are at risk for what? why?
|
thyrotoxicosis because of the passage of thyroid stimulating immunoglobulin across the placenta.
|
|
vaginal SCC tx options
|
stage 1 and II less than 2 cm -> surgical
otherwise, radiation therapy also take into account age and comorbid conditions when deciding on surgery vs radiation |
|

Vaginismus def and tx
|
vaginismus = involuntary contraction of the perineal musculature. underlying cause is psychological
tx: relaxation, kegel exercises to relax vaginal muscles, and insertion of dilators,fingers, etc to bring about desensitization |
|
granulosa cell tumor
|
fairly common and represent 10% of all solid malignant ovarian tumors -> secrete excessive estrogen -> precocious puberty!
with virilizing sx, think of excessive androgens |
|
main role of hCG
|
secreted by syncytiotrophoblast and is mainly responsible for the preservation of the corpus luteum during early pregnancy
|
|
Primary amenorrhea with confirmed uterus - next step?
|
last test - 8
|
|
abdominal pain in a young female in the middle of her cycle
|
most likely mittelschmerz (midcycle pain)

|
DES exposure increases risk of what?
|
clear cell adenocarcinoma of the vagina and cervix
cervical anomalies and uterine malformations |
|
magnesium sulfate toxicity in the setting of pre-eclampsia -> alternative tx?
|
calcium gluconate
toxicity: decreased deep tendon reflexes, followed by respiratory depression |
|
epidural anesthesia can cause what side effect and through what mechanism?

hypotension -> blood redistribution to the lower extremities and venous pooling due to sympathetic fiber block that results in vasodilation of the lower extremity vessels
|
|
Plan B - medical name, ideal time frame

Levonorgestrel -> given 120 hours after unprotected intercourse
this is a progestin only method effectiveness greater the earlier medication is administered prevents 7 out of 8 pregnancies |
|
Fetal hydantoin syndrome
|
exposure to anticonvulsant meds
small body size, microcephaly, digital hypoplasia, nail hypoplasia, midfacial hypoplasia, hirsutism, cleft palate, rib anomalies |

oxygen and change maternal position
uterotonic drugs need to be discontinued and maternal hypotension evluated and treated variable decelerations may require amnioinfusion, which consists of infusion of fluid into the amniotic cavity |
|
fibroids
|
most common pelvic tumor seen in women. usually present as pelvic masses with sx due to compression of adjacent organs (constipation, urinary frequency) and heavy, prolonged menstrual bleeding. bleeding between cycles nad postmenopausal bleeding are not typical for leiomyomas
diagnosed with ULTRASOUND (no need for CT) as it has a higher sensitivity than CT for both uterine and ovarian pathology. US also avoids putting pt at risk of radiation. |
|
diagnosing acute appendicitis on a pregnant female
|
US with graded compression technique: noncompression and dilation of the appendix are diagnostic of appendicitis.
if nondiagnostic, MRI can be performed |
|
ruptured ectopic pregnancy
|
typically with diffuse abdominal pain, cervical and adnexal tenderness, lightheadedness, and hemodynamic instability. mgmt includes urgent surgical evaluation.
|
|
rubella vaccine for pregnancy
|
women generally advised to avoid live vaccines immediately before and during a pregnancy. wild type rubella has been a/w significant adverse fetal effects, but hte vaccine strain has not.
women who are inadvertently given rubella vacination bbefore or during pregnancy do not require additional intervention and may proceed with routine prenatal care. |
|
ruptured ovarian cyst
|
p/w acute onset of unilateral pelvic pain immediatley after strenuous activity or sexual intercourse. Pelvic US can confirm the dx by showing free fluid in the pelvis.
supportive care (eg analgesics) is recommended for uncomplicated cyst rupture; complicated cyst rupture may require surgical intervention) |
|
ovarian and adnexal torsion
|
most commonly in women of reproductive age. primary risk factor is ovarian enlargement (pregnancy, tumors). pts develop sudden onset of unilateral lower abdominal pain (usually right sided), N/V.
dx confirmed with US using color DOppler. mgmt includes laparascopic surgery distinguished from ruptured ovarian cyst bc it has following features: usually after strenuous physical activity, accompanied by light bleeding, NO significant N/V. |
