Acute Abdominal/Pelvic Pain in Women 12160
Recurrent mild & unilateral mid-cycle (around day 14) pain prior to ovulation
Pain lasts hours to days
No peritoneal signs
Ultrasound: Not indicated
Rupture of the follicle releases the egg; concomitant release of some blood during process irritates peritoneum
Reassure patients
Ruptured ovarian cyst
Sudden-onset, severe, unilateral lower abdominal pain immediately following strenuous or sexual activity
Nausea & vomiting
Unilateral, tender adnexal mass on examination
Can cause hemoperitoneum often while on anticoagulants
Diffuse severe abdominal pain, pleuritic chest pain, and shoulder pain (due to phrenic nerve irritation)
Gynecologic emergency typically occurring in premenopausal patients
Diffuse abdominal rigidity with rebound and guarding is present
Symptoms arise due to ischemia and eventually necrosis
Decreased hematocrit due to intra-abdominal blood loss
Twisting around its supporting structures (infundibulopelvic ligament or utero-ovarian ligament) which contains ovarian blood supply
Ultrasound + Doppler: Pelvic free fluid and possible adnexal mass if the cyst is incompletely drained
Enlarged ovary with decreased or absent blood flow
Dermoid cysts in particular have a higher likelihood of torsion than other types of ovarian masses
Treatment: prompt surgical laproscopy with detorsion, cystectomy, possibly removal of the adnexa (if necrosis despite restoration)
Untreated torsion may lead to chronic pelvic pain, infertility, hemorrhage, or peritonitis and sepsis

Normal Physiological Changes During Pregnancy 2804
Multiple skin tags
Nocturnal leg pain is also common due to muscle cramping from lactic and pyruvic acid accumulation
Increased Glomerular filtration rate & renal size
Increased cardiac output & renal blood due to progesterone with increased renal excretion
Decreased blood urea nitrogen & serum creatinine
Urinary frequency, nocturia
Increased urine output & sodium excretion
Mild hyponatremia
Hormones reset threshold to to increase ADH release from pituitary
Increased basement membrane permeability --> increased renal protein excretion
Dilutional anemia
Increased Plasma volume & red blood cell mass
Prothrombotic state
Hormone mediated decrease in total protein S antigen & activity; increase in fibrinogen & coagulation factors
Pregnant patients often have mildly decreased (> 70,000/mm3) platelet counts, a condition known as gestational thrombocytopenia
Increased Heart Rate
Decreased systemic vascular resistance
Systolic ejection murmur
Decreased blood pressure
Chronic respiratory alkalosis with metabolic compensation, increased PaO2 & decreased PaCO2 (metab comp with decrease HCO3)
Progesterone directly stimulates central respiratory centers (medulal) to increase tidal volume & minute ventilation
Decreased functional residual volume
Hgb goes down because its a concentration but theres both more plasma and RBCs (just even more plasma)
Tidal volume (VT) increases
Functional residual capacity decreases
Clotting factors increase (VII, VIII, X, von Willebrand) and anticlotting factors decrease (Protein C, Protein S, and Antithrombin III)
↑ Fibrinogen (so “normal” fibrinogen at delivery is likely DIC); ↑ D-Dimer (so dont use D-dimer for thrombosis testing)
Creatinine should decrease through pregnancy. “Normal” values at the upper end of normal should be considered pathologic

hCG 580
Source: Syncytiotrophoblast of placenta
Other functions include promotion of male sexual differentiation and stimulation of the maternal thyroid gland
Production begins at day eight after fertilization, levels double every 48 hours until they peak at six to eight weeks gestation
Placental hormone secretion generally increases over the course of pregnancy, but hCG peaks at 8–10 weeks
Maintains corpus luteum (and thus progesterone) for first 8–10 weeks of pregnancy by acting like LH (otherwise no luteal cell stimulation causes abortion)
After 8–10 weeks, placenta synthesizes its own estriol and progesterone and corpus luteum degenerates
Used to detect pregnancy because it appears early in urine (2 weeks) or via blood (1 week)
Has identical α subunit as LH, FSH, TSH (states of increased hCG can cause hyperthyroidism)
β subunit is unique (pregnancy tests detect β subunit)
hCG is increased in multiple gestations, hydatidiform moles, choriocarcinomas, and Down syndrome
hCG is decreased in ectopic/failing pregnancy, Edward syndrome, and Patau syndrome
Stimulates the production of thyroid hormones by binding to thyrotropin (TSH) recepto rs on thyroid follicular cells
picmonic thumbnail
Estrogen 577
Source: Ovary (17β-estradiol), placenta (estriol), adipose tissue (estrone via aromatization)
Potency: estradiol > estrone > estriol
Induction of prolactin production during pregnancy
Development of genitalia and breast, female fat distribution
Growth of follicle, endometrial proliferation, increased myometrial excitability
Upregulation of estrogen, LH, and progesterone receptors; feedback inhibition of FSH and LH, then LH surge; stimulation of prolactin secretion
Increased transport proteins, SHBG, thyroxine-binding globulin; increased HDL; decreased LDL
50-fold increase in estradiol and estrone
1000-fold increase in estriol (indicator of fetal wellbeing)
Estrogen receptors expressed in cytoplasm; translocate to nucleus when bound by estrogen
Increased GnRH receptor on anterior pituitary
LH stimulates desmolase in theca cells to form androgen from cholesterol
FSH stimulates aromatase in granulosa cells to make androgens into estrogen

Acute Mastitis, Periductal Mastitis and Mammary Duct Extasia (
Acute mastitis
Staph Aureus infection
Associated with breast feeding (fissures develop in nipple and bacteria enter)
Erythematous breast, purulent nipple discharge, may have abscess
Continue breastfeeding, dicloxacillin
Periductal mastitis
Usually seen in smokers
Smoking causes relative Vit A decifiency, Vit A deficiency causes squamous metaplasia of periductal cells
Cells produce keratin and block the duct resulting inflammation
Subareolar mass with nipple retraction - due to inflammation and fibrosis
Mammary duct ectasia (dialation)
Chronic inflammation that causes dilation (ectasia) of subareolar duct
Periareolar mass with green-brown nipple discharge
Plasma cells on biopsy
Rare; classically arises in muliparous postmenopausal women

Epithelial Ovarian Carcinoma 12052
Epithelial ovarian carcinoma refers to a malignancy involving the ovary, fallopian tube, and peritoneum
Clinical Presentation
Acute: Shortness of breath, obstipation/constipation with vomiting, abdominal distension, ascites, decreased bowel sounds
Subacute: Pelvic/abdominal pain, bloating, early satiety
Firm, non-mobile pelvic mass with nodularity in a postmenopausal patient is concerning for EOC
Asymptomatic adnexal mass
Occurs primarily in postmenopausal women and women with BRCA mutations
Laboratory findings
Increase CA-125
CA-125 testing has particularly low specificity in premenopausal women, not used during initial evaluation
Useful mainly in postmenopausal women and is not recommended for the initial evaluation of an adnexal mass in premenopausal patients
Ultrasound findings
Solid mass
Thick septations
Pelvic ultrasonography is the first-line test for evaluation of a palpable adnexal mass
Exploratory laparotomy
The ovaries, uterus, omentum, and any cancerous lesion will be removed and pelvic and paraaortic lymph nodes will be dissected
Chemotherapy with platinum-based agents is initiated after surgery
O: Paclitaxel
The ideal time for surgery is in the early second trimester
Chemotherapy can be admin istered in the second and third trimesters , although recommendations vary depending on the tumor type
Don't biopsy, risk of seeding
Risk factors
Family history
Genet ic mutations (BRCA 1, BRCA2)
Age ≥50
Hormone replacement therapy
Endomet riosis
Inferti lity
Early menarche /late menopause
Protective factors
Oral contraceptive pills

Contraindications to External Cephalic Version 3118
Offered at 37 weeks
External cephalic version (ECV) involves maneuvers to convert a breech into a vertex presentation for delivery
ECVs has potential to cause fetal distress, perform only when arrangements have been made for a back-up emergency cesarean delivery
Internal podalic for twin delivery to convert the second twin from a transverse/oblique to a breech for subsequent delivery
Indications for cesarean delivery regardless of fetal lie (eg, failure to progress during labor, non-reassuring fetal status)
Placental abnormalities (eg, placenta previa or abruption)
Ruptured membranes
Hyperextended fetal head
Fetal or uterine anomaly
Multiple gestation
Abnormal fetal heart tracings
Classical C section as its not advised to proceed with vaginal birth afterwards
Active labor is a relative contraindication for external cephalic version

Syphilis - Diagnostic Serology 4792
Negative screening but strong clinical evidence of primary syphilis (chancre) --> empiric intramuscular benzathine penicillin G
Repeat nontrep serology in 2-4 weeks (establish baseline titers); 4-fold titer decrease at 6-12 months --> adequate treatment
First prenatal visit testing, if one is positive then confirm with the other (high false positive rate)
Penicillin allergy should have a penicillin skin test to evaluate for the presence of an lgE-mediated response
If positive, desensitize patient to penicillin before treatment with intramuscular penicillin G benzathine
1 dose weekly for 3 weeks
Nontreponemal (RPR, VDRL)
Antibody to cardiolipin-cholesterol-lecithin antigen
Quantitative (titers)
Possible negative result in early infection
Nontreponemal tests may have higher false-negative rates (20%-30%) in patients with primary syphilis
Decrease in titers confirms treatment
Treponemal (FT A-ABS, TP-EIA)
Antibody to treponemal antigens
Qualitative (reactive/nonreactive)
Greater sensitivity in early infection
Positive even after treatment
