OBGYN UW1 Flashcards
(195 cards)
HELLP (hemolysis, elevated liver enzymes, low platelets) syndrome presentation during pregnancy
-worsening RUQ pain due to gradual distension of hepatic (Glisson) capsule
-HTN
-proteinuria
life threatening complication of preeclampsia with severe features
-pulmonary edema
-caused by increase SVR, capillary permeability, and pulmonary capillary hydrostatic pressure and decreased serum albumin levels
preeclampsia with severe features presentation
greater or equal 20weeks + HTN (140/90) + HA with vision changes (blurry vision)
increases risk of acute stroke due to endothelial cell damage, dysregulation of cerebral blood flow, cerebral vasospasm, vascular micro thrombi formation
Complete abortion
passage of products through cervix at <20weeks
-cervix then closes
-pain and bleeding subside
-Ultrasound: empty uterus
Transverse lie: presentation and management
-fetal spine perpendiculat to long axis of uterus
-common at early gestational ages
-most spontaneously convert to longitudinal lie and cephalic by term (equal or greater 37w)
-preterm transverse lie manangement: expectantly
acute postpartum urinary retention: presentation and RF
-inability to void and overflow incontinenece due to pudenal nerve injury and bladder atony
-RF: prolonged labor, perineal trauma, regional neuraxial anesthesia
Granulosa cell tumor results in?
Granulosa cells: primary component of ovarian stroma. converts testosterone to estradial via aromatase
-high levels estrogen and inhibin
-malignant proliferation results in high estradial levels that affect breast tissue (tenderness, fibrocystic changes) and uterine lining (postmenopausal thickened endometrium)
-juvenile subtype granulosa cell tumors present with precocious puberty and adnexal mass
What is ulipristal? MOA
-highly effective emergency contraception
-delays ovulaton and impair implantation
-can take up to 120 hours after unprotected sex
What is the most accurate way to deteremine estimated gestation age?
Ultrasound dating with fetal crown-rump measurement in 1T
Signs concerning for breast malignancy (unilateral, blood tinged breast milk or bloody nipple discharge, new breast mass) NBS?
breast imaging
What is cervical insufficiency?
structural weakness of cervix that causes painless cervical dilation and potential 2T pregnancy loss.
managed with prophylactic cerclage performed in 1T to decrease risk of recurrence
RF for cervical insuffiency
prior cone biopsy (cervical conization)- shortens cervix and alters structural integrity
Nonclassic congenital adrenal hyperplasia cause and presentation
-partial 21 hydroxylase deficiency
-reproductive age with hyperandrogenism (hirsutism, acne) and AUB
Cervical cancer cause and presentation
-cause: high risk 16/18 HPV
-an AIDS defining illness
-px: postcoital bleeding, painless ulcerative lesion, painless inguinal lymphadenopathy, irregular bleeding, vaginal discharge, visible raised cervical lesion
confirm: biopsy
Why are estrogen containing contraceptives contraindicated in pts with migraine with aura?
-increase for ischemic stroke
-migraine: episodic, severe, unilateral throbbing HA; photophibia, phonophobia, N/V, aura (focal, reversible, neurologic symptoms that precede or accompany HA)
What is physiologic leukorrhea?
-white, odorless mucoid cervical discharge occurs midcycle due to increasing estrogen prior to ovulation
-microscope: no evidence of inflammation or infection (rare polymorphonuclear leukocytes)
Uterine rupture: px, RF, mx
-Px: ab pain, fetal heart tracing abnormalities, progressively decreasing contraction amplitude, loss of fetal station
-RF: prior uterine surgery (C section)
-Mx: emergency laparotomy and C section
What is androgen insensitivity syndrome?
-nonfunction androgen receptor
-genotypically male (46XY) to appear phenotypically female
-primary amenorrhea (due to lack of female internal genitalia), normal breast and female external genitalia, minimal or no axillary/pubic hair
Benign breast pain signs
-cyclic (a.w menses), bilateral, and diffuse, no mass
-reassure and symptom management (supportive bra, NSAIDs)
Management of uncomplicated (no fever or purulence) perineal lacerations
-common after vaginal delivery
-causes perineal edema and pain with urination
-Mx: conservative (NSAIDs, sitz bath)
Gestational diabetes mellitus screening when?
-at 24-28 weeks
-earlier screening (at initial prenatal visit): for pts with obesity and additional RF for undiagnosed pregestational DM (prior macrosomic infant, PCOS)
What is postpartym thyroiditis?
-form of painless AI thyroiditis within 12 months of delivery
-px: signs of hyperthyroidism (weight loss, tremor, elevated T4 and T3) and low uptake on RAI uptake scan
Stress urinary incontinence occurs due to? txt?
-Weakened pelvic floor muscles that cause urethral hypermobility and reduced bladder support
-intermittent loss of urine from increased intraabdominal pressure (lifting, coughing, laughing, jogging, sex)
-first line txt: pelvic floor muscle (Kegel) exercises or surgical midurethral sling placement
-common in postmenopausal women due to weakened pelvic floor muscles and urogenital mucosa atrophy
Ovarian torsion: px and mx
-rotation of ovary around infundibulopelvic ligament, causing ovarian vessel occlusion and ischemia
-px: n/v, new onset severe unilateral pelvic pain, adnexal tenderness, palpable adnexal mass
-mx: emergency requiring diagnostic laparoscopy
