  • Pregnant female with hypertension + proteinuria + edema + malar rash & positive ANA titer(to differentiate preeclampsia from SLE) = is suspicious of SLE  which frequently causes glomerulonephritis which lead to :

          1. Proteinuria

          2. Hematuria

          3. RbCs cast

    • MgSo4 toxicity :

    - Pregnant female + was treated by MgSo4 for severe preeclampsia & eclampsia  after hours of treatment she developed : 1- Depressed tendon reflexes (earliest sign).

    2- Respiratory depression (second sign).

    The most appropriate next step is: Stop MgSo4 & give calcium gluconate.

    • Hypertension before 20 weeks without protienuria, either :

    1- Chronic hypertension  occurred before pregnancy (U/S reveals normal gestaional sac) 2- Hydatiform mole  U/S reveals "snow storm appearance".

      • Hypernatremia + Hypokalemia  Hyperaldosterenism.

      • Follow up for protenuira & higher BP  if occurred it's : chronic HTN with superimposed pre-eclampsia.

      • Hypertension is most serious risk factor of : Placental abruption / IUGR / Oligohydraminos/Preterm labour. Risk Factors :

    Uncontrolled DM

    Placenta previa

    Uterine atony

    Posterm pregnancy

    Macrosomia

    • Prior C.S.

    -Multiparity.

    • Multiple gestation.

    • Maternal age is old.

    - Post-partum hemorrhage - Uterine distention: Multiple gestation , polyhydraminos.

    Repeated post-term pregnancies increase risk.

     Hellp syndrome

    - Triad of :

    1. Thrombocytopenia (low platelet count) .

    2. Microangiopathic hemolytic anemia (↑ indirect bilirubin & RBCs fragments on blood smear)

    3. Increased liver enzymes in a patient with preeclampsia (mild hypertension & mild proteinuria) is defined as HELLP syndrome.

     The most appropriate next step in management in :

    1. Induce labor immediately :

        • In women beyond 34-weeks (fetal lungs are mature).

        • OR presence of signs of fetal or maternal deterioration.

    1. If below 34 weeks  depends on the state of the mother & the fetus: a- Any deterioration : requires Stabilization + Delivery.

    b- BUT if fetal well-being is ascertained + mother is stabilized  Dexamethasone & delivery :

        • After 34 weeks or

        • When fetal lungs become mature.

    • Mild coagulopathy correct spontaneously after delivery.

    • Platelets transfusion is needed only when there is advanced coagulopathy.

    Hemolytic uremic syndrome :

    • Triad of :

      1. Renal failure.

      2. Microangiopathic hemolytic anemia.

      3. Thrombocytopenia.

    • Treatment: Plasmapheresis

    Acute fatty liver of pregnancy (AFLP) :

    Causes : Acute hepatic failure, in the third trimester or early post-partum period.

    (Prolonged PT , PTT + moderate elevation transaminases level.)

    Acute viral hepatitis :

    • Lab : elevation of transaminases level into thousands.

    • Clincally: constitutional symptoms  nausea , vomiting , clay-colored stools , dark-urine , clinical jaundice.

    Idiopathic (immune) thrombocytopenic purpera :

    - Characterized by autoimmune destruction of platelets - Patient manifest with :

    1. Bleeding from skin & gums.

    2. Hypersplinism.

    Gestational diabetes

    1. Screening test 1h 50-g Oral Glucose Challenge Test (OGCT)

      • Screening should be performed between 24 to 28 weeks.

      • Screening is advised at the first prenatal visit in pregnant women with risk factors.

     Without regard to time of day or time of last meal (no fasting state is needed):

    Plasma glucose level is measured 1 hour after a 50-g glucose load

          • Normal Value : < 140 mg/dl

          • Abnormal Value: >= 140 mg/dL identifies 80 % of all women with gestational diabetes.

    - An abnormal screening GCT is followed with a diagnostic : 3-hour 100-g oral glucose tolerance test.

    1. Diagnostic test 3h 100-g oral glucose tolerance test (OGTT)

     After an overnight fast , a fasting blood sugar (FBS) is drawn :

            • If FBS > 125 mg/dl , indicates overt diabetes mellitus No further testing is performed

            • If FBS < 126 mg/dl  Administer a 100-g glucose load, and check glucose levels hourly for 3 hours.

            • If two or more abnormal values : Patient is diagnosed with GDM

            • If only one value is abnormal :Impaired glucose tolerance

            • Treatment :

      1. First treated by: trial of diet control.  aim of fasting glucose is : 75 – 90 mg/dl.

      2. If not responding (fasting > 90 mg/dl): most appropriate step is : Insulin therapy (not continuing the diet control)

    • The baby at risk to be born with :

      3)

       Hyperviscosity ( due to polycythemia)

      1.  Hypoglycemia ( due to high baseline insulin in fetus) 2)  Hypocalcemia ( due to PTH suppression)

    4)  hyperbilirubenemia ( due to breakdown of RBCs)

    Hyperemesis Gravidarum :

    • is a severe form of vomiting usually begins between 4 and 10 weeks (if they begin after week 10 or do not resolve by week 20, then another etiology should be suspected.)

    • While it can be managed successfully with supportive therapy (fluids and nutrition) and generally resolves on its own by mid-pregnancy  Other causes of severe vomiting during pregnancy must be ruled out :

    Gestation Trophoplastic Disease (hydatidiform mole & choriocarcinoma) is one disease to consider in such cases.

    • The classical clinical triad for hydatidiform mole :

      1. Enlarged uterus,

      2. Hyper emesis

      3. Markedly elevated beta HCG ( >100,000).

    The most appropriate initial next step in evaluation of severe vomiting during pregnancy is :

    measuring quantitative B-hCG levels.

     If it is markedly elevated  Ultrasound should then be performed (to exclude molar disease !)

    • Remember that :

     Some degree of nausea & vomiting affect 50 – 90% in pregnant females BUT In hyper emesis gravidarum women have :

          1. Persistence of vomiting

          2. loss of >= 5% of Pre-pregnancy weight 3) Presence of ketonuria.

     Mild increase in ALT, AST/bilirubin/amylase , lipase (from salivary gland due to vomiting)  The differential dx includes:

    1- Pyelonephritis / 2- GTD / 3-Gastroenteritis / 4- Hepatobiliary disease.

    Viral Hepatitis

    - Presents with: fever+ Rt upper quadrant pain . - More dramatic increase in AST , ALT.

    DKA

    • anion gap metabolic acidosis

    • This patient instead presents with:  HCO3 , suggesting alkalosis from vomiting.

    • Presence of urine ketones is due to starvation rather than insulin deficiency.

    Molar pregnancy

    - Presents with: abnormal high level of B-hCG + abnormal U/S

    Hyperthyriodism

    - Can present with hyperemesis BUT with : tachycardia + tremors + diarrhea.

    Prolonged labor :

    • Women with prolonged labor ?!

    1) Check for adequate uterine contractions  2-3 min. lasts 45-60 second.

    - If no adequate contractions : give IV Oxytocin.

    2) Assess cervical dilatation (in first stage):

    - Arrest of cervical dilatation : >= 2 hours for primi & multi TTT due to cephalopelvic disproportion ( maternal

    3) Assess fetal descent (in 2 nd stage) : pelvis abnormality as: prominent ischial spines):

        • Arrest of descent : < 2h for primi / < 1h for multi Low transverse C.S

    (+ 1h if epidural anesthesia)

    Pre-term labor :

        • Uterine contractions >= 4 per 20 min. + cervical changes / after 20 weeks and before 37 weeks.

        • Treatment : Depends on Date of gestation + Morbidities to mother to fetus :

    1) If normal labor  Gestational age between 24 & 34 weeksgive tocolysis to maintain pregnancy for at least 48 h. to allow administration of systemic corticosteroids  decrease risk of RDS.

    In acute pre-term labor , bed rest and tocolysis are continued as long as possible with a long term goal of reaching 34-36 weeks GA.

    2) If the fetus is distressed with repetitive late deceleration indication of : Ceasrean section.

     Because he is not likely to withstand the stress of vaginal labor.

    • Should allow spontaneous labor IF  preterm labor & by U/S there is severe congenital anomaly incompatible with life as : Bilateral Renal Agenesis  decrease AF  Lung hypoplasia (can't live outside uterus).

    Preterm Premature Rupture of Membranes (PPRM) : diagnosed clinically as gush or leakage of fluid.

      • The most important complication : pulmonary hypoplasia.

        -

        If pregnancy < 34 weeks GA + L/D ratio is < 2.0 most important next step is : betamethasone.

        -

        If pregnancy >34 weeks GADelivery is usually recommended.

      • No tocolysis is needed if there is not uterine contractions.

      • AF index is normally ( >5 & <25 )  amnioinfusion is sometimes used in oligohydraminos.

      • As long as Non-stress CTG is normal  NO C.S is indicated.

                • Normal AF pH is : 7.0 – 7.5

                • Normal vaginal pH: 3.8 – 4.5

    More neutral pH of the fluid described in this patient indicates it's of amniotic origin.

     The most appropriate next step in management is : Penicillin prophylaxis.

    • Chorioamnionitis :

      • should be suspected in mothers presenting with prolonged or premature rupture of the membranes + fever + any of the following findings:

              1. Maternal tachycardia ( > 100/min),

              2. F etal tachycardia ( > 160/min)  is a sign of maternal infection NOT fetal distress ! 3- Maternal leukocytosis (> 15,000/mm3),

              1. Uterine tenderness

              2. foul smelling amniotic fluid.

      • Treatment :

    1- First intervention is to tx the mother with broad spectrum antibiotics since it is : polymicrobial infection :

    - Clindamycin IV & - Gentamicin IV.

    2- Concomitantly with immediate delivery of the fetus :

    A) If in question is having regular uterine contractions  oxytocin administration & vaginal delivery. B) If in question there fetal distress  C.S

    Prolonged (postterm) pregnancy :

      • is defined as any pregnancy at or beyond 42 weeks gestational age measured from the last menstrual period.

      • Management with either : 1) Induction of labor  in favorable cervix.

    2) Expectantly  in unfavorable cervix.

      • Twice weekly monitoring with ultrasound is required to evaluate for oligohydramnios in postterm pregnancies because  amniotic fluid can become reduced within 24 to 48 hours.

     Oligohydramnios in these cases is defined as :

              • No vertical pocket of amniotic fluid greater than 2cm or - an AFI of 5cm or less.

    Intrauterine Fetal Demise (iufd) :

              • Fetal death after 20 weeks and before onset of labour (( SUSPECTED BY ABSENCE OF FETAL MOVEMENTS )) - Next most appropriate test used to confirm diagnosis is : Real-time U/S is more reliable tool which shows: absence of fetal movement & cardiac activity.

              • If confirmed , Next stepCoagulation profile to detect DIC ( due to release of thromboplastin from placenta to maternal blood) - Diagnosis :

    Fibrnogen value in low normal level ( e.g 160 with N.level: 150 – 450 mg/dl ) + Platelets in low normal value (<150,000) are early sign of DIC induction of labor , is most appropriate next step.

    Especially if associated with :  Platelet count + PT , PTT + Fibrin splits products.

              • Management :

    1) If any coagulopathy is suspected The most appropriate step is : Induction of labour.(without delay)

    Fresh Frozen Plasma

    If :

    1- Coagulation profile is profoundly abnormal (fibrinogen < 100 mg/dl) 2- If DIC or hemorrhage is evident.

    Platelet transfusion & plasminogen replacement

    If :

    1- Coagulation profile is profoundly abnormal (fibrinogen < 100 mg/dl)

    C.S

    Vaginal Delivery is sufficient to decrease risk of DIC C.S will increase risk of surgery complications

    Expectant Treatment

    Not suitable if low normal level of fibrinogen and platelets  will develop DIC.

    2) If Coagulation profile is normal

    Discuss need for delivery & review options for vaginal versus C.S.

              • Watchful expectancy  labor occurs spontaneously in 80% of cases within 2-3 weeks of IUFD.

              • Induction of labor, either vaginal versus C.S.

    Should have immediate induction of labor

    It's not necessary as ifcoagulation profile if normal  as patient is not in immediate danger

    Recommend C.S as soon as possible

    - It's not necessary as births of term infants are routinely done in women following C.S - The delivery of 30 week IUFD vaginally may possible ( if her cervix is favorable is the question) and would avoid risks of operation.

    Autopsy of the fetus & placenta

      •  should be performed after 1st episode of IUFD , in order to prevent , if possible , a recurrence of the same issue in subsequent pregnancies.

            • There is 1 – 8% risk of recurrent still birth in mothers who have previously experienced IUFD.

            • Serial B-hCG monitoring is indicated if there suspected molar pregnancy.

            • Serial fibrinogen testing  is indicated to detect DIC if IUFD is managed expectantly

    Fetal Growth Restriction (FGR):

    • Smoking cessation : is the single most prevalent preventable cause of IUGR in the united states  which have 3 – 4 fold increase risk of having a growth restricted infant.

    • FGR is suspected when there is at least 3 cm less than the actual gestation age in weeks ( e.g. GA: 30 weeks and fundal height is: 26 cm )

    Symmetrical

    Asymmetrical

    • Insult to the fetus occurs

    • Growth of both head & body is defici

    < 28 weeks .

    ent

    • Insult to the fetus occurs

    • Normal head size & reduced circumference.

    > 28 weeks .

    Abdominal

    - Typically the result of fetal defects su anomalies genetic anomalies or early infections (TORCH).

    ch as genetic

    congenital

    • Results from fetal redistribution of blood flow to vital organs ( such as the brain, heart, placenta) as the expense of less vital organs (abdominal viscera)

    • Maternal factors such as HTN, hypoxemia, smoking, vascular disease and toxic esposures.

    Asymmetric has better prognosis than Symmetric

      • Abdominal circumference is the most reliable index for estimation of fetal size because: it is affected in both symmetric and asymmetric fetal growth restriction.

      • Biparietal diameter will be :

     Normal or close to normal in asymmetric FGR as blood is preferentially shunted to supply the fetal brain  Decreased, in symmetric FGR.

      • Femoral length : Used to estimate fetal size BUT as not accurate as AC.

    E arly pregnancy bleeding :

    • Maintenance of airway , breathing , circulation is always first priority in any patient came to ER with antepartum hemorrhage  Most appropriate next step is: obtain venous access with 2 large bore cannulas (Hemodynamic resuscitation) in any patient hemodynamically unstable " Hypotension / tachycardia / cold exteremities

    1. Ectopic Pregnancy : ( presents with unilateral adenxal tenderness + normal vital signs"non-ruptured" )

      • Patient present with +ve pregnancy test  3 differential diagnosis :

    Early viable intrauterine pregnancy

    Ectopic pregnancy

    Non-Viable intrauterine pregnancy (complete abortion)

    Initial test is U/S  if undetermined : next step is serial B-hCG measurements :

    Doubling every 48 hour

    Increase at slower rate

          • Transabdominal U/S detect gestational sac at 6 weeks when B-hCG > 6,500 IU/ml.

          • Transvaginal U/S detect gestational sac when at 5 weeks when B-hCG 1,500 – 2,000 IU/ml.

    • If the B-hCG < 1.000 IU/mlboth B-hCG & transvaginal U/S should be repeated in 2-3 days (providing the patient is

    hemodynamically stable)

    • Once B-hCG between 1,500 – 6,500 IU/ml  next appropriate step is to do : Transvaginal U/S , with 3 possibilities : 1) If revealed intrauterine sac : Normal pregnancy.

      1. If revealed adenxal sac : Ectopic pregnancy

      2. If neither are revealed , next step is serial B-HCG measurements ( repeat B-hCG in 48 hours) :

            • If doubling every 48 h. suggest : normal pregnancy

            • Slower rise in B-hCG suggest : abnormal pregnancy.

    Laparoscopy

    - Despite being the gold standard for diagnosis of ectopic  B-hCG & transvaginal U/S are enough for diagnosis.

    Methotrexate

    • is used for medical management of non-ruptured ectopic pregnancy providing : 1- Sac < 3.5 cm

      1. B-hCG < 6.000 UI/ml

      2. Non-viable fetus

      3. No history of folic supplementation

    • Given at 4 – 7 days  if no decrease in B-hCG > 15%  repeat another course at 11-14 days  if no decrease in B-hCG > 15% : Surgry (Salpingectomy / or Salpingestomy).

    D & C

    - It's indicated when:

    1- Pregnancy has been confirmed to be non-viable via serial B-hCG AND 2- Location of pregnancy cannot be determined by : U/S.

    1. Abortion:

    • Threatened abortion  Any hemorrhage occurring before 20th weeks of gestation with : Live fetus + closed cervix. - The most appropriate next step in management is : Reassurance & outpatient follow up.

    • Inevitable abortion Vaginal bleeding, Colicky lower abdominal (suprapubic ) pain that radiate to back + - Dilated cervix & products of conception can be seen through it.

      • U/S shows: ruptured sac with absence of fetal cardiac motion.

      • Most appropriate next step in management is: IV fluids + suction curettage + RhoGAM administration if Rh-ve

    Suction curettage is the treatment of choice in inevitable abortion because the pregnancy can't be maintained  need to be evacuated , So any choices as conservative treatment is not enough.

    • Incomplete abortion  Vaginal bleeding, lower abdominal cramps that radiate to back +

      • Dilated cervix + Evacuation of some fetal tissue - U/S shows: retained some products of conception .  Complete abortion

      • Colicky suprapubic pain(uterine contractions) + dilated cervix & passage of whole fetal tissue along vagina with moderate bleeding( No retained products of conception)  followed by ceasing of pain & closing of cervix.

      • P hysical examination shows: Closed cervix + blood pooled in vaginal vault. - U/S shows: empty uterus

    • Missed abortion :

      • Spontaneous abortion < 20 weeks GA & fetal weight < 500 gm.

      • Fetal demise + retained products of conception + closed cervix

      • Loss of pregnancy symptoms ( nausea & vomiting , breast tenderness )+ brown vaginal discharge.

      • The most appropriate next step in diagnosis of spontaneous abortion is transvaginal U/S to : 1) Document presence of uterine contents.

    2) Visualize heart motion.

      • Most appropriate next step in management is removal of contents of conception with either: 1) Surgical: Dilatation & Curettage.

        1. Medical : Misoprostol

        2. Expectantly , with serial imaging to ensure complete expulsion of the contents.

    • Septic abortion :

      • Female came to emergency department with 2 days history of: fever + shaking chills + lower abdominal pain WITH a history of abortion 3 days ago.

      • Physical examination :

          • Lower abdominal tenderness

          • Enlarged , tender uterus with a dilated cervix = with purulent , offensive discharge coming from it.

      • Treatment:

     The most appropriate sequence in management is :

    Cervical & blood culture , antibiotics , gentle suction curettage (in sequence)

    First obtain blood and cervical/endometrial cultures, then give IV broad spectrum antibiotics Immediate surgical evacuation by gentle suction curettage ( vigoruous curettage may cause uterine perforation) of the uterine contents is then required in order to remove the infectious nidus.

    • Physicians can refuse to perform elective abortions for personal or professional reasons. If you refuse to perform any procedure then you should: refer the patient to another physician who can and will.

    Diethylstillbestrol (DES):

    • Synthetic preparation possessing estrogen proprieties, which was widely used between 1947 & 1971 for treatment of threatened abortion.

    • Female offspring of women who ingested DES during their pregnancy are at increased risk of developing : 1- clear cell adenocarcinoma of the vagina & cervix .

      1. Carvical anomalies.

      2. Vaginal malformations.

     The most important risk factor for squamous cell carcinoma of cervix & vagina : HPV.

    3- hydatiform mole :

    • The increased in BP that appears before 20 weeks gestation is either : chronic HTN or hydatiform mole.

    • Gestational hypertension (formerly known as pregnancy-induced hypertension) is idiopathic hypertension without significant proteinuria (< 300 mg/L) that begins in the second half of pregnancy, during labor, or within 48 hours of delivery.

    • Some patients may go on to develop preeclampsia.

    • Retrospective diagnosis is made 1–12 weeks after delivery.

    A ntepartum hemorrhage :

    • Maintenance of airway , breathing , circulation is always first priority in any patient came to ER with antepartum hemorrhage  Most appropriate next step is: obtain venous access with 2 large bore cannulas (Hemodynamic resuscitation) in any patient hemodynamically unstable " Hypotension / tachycardia / cold exteremities

    • Placental abruption (antepartum hemorrhage) :

      • Premature placental separation initiated by hemorrhage in the decidua basalis.

      • High index of suspicion in patients presenting with Painful 3rd trimester bleeding "dark-red" (maternal in origin) , (bleeding can be concealed in 20% of cases) with normal U/S , with :

          1. Uterine tenderness

          2. Uterine hyperactivity

          3. Uterine tone is increased

    N.B: absence of blood of pelvic exam doesn't rule out this condition

      • U/S detects as few as 25% of all placental abruptions  role of U/S in ante-partum hemorrhage is primarily to rule out placenta previa and NOT to diagnose placental abruption.

      • Treatment :

        • If patient is unstable (hypotensive, tachycardia) + continued bleeding + FHR is alarming :

            1. Obstetrical indications OR Unfavorable cervix (early stage) Emergency (immediate NOW!) C.S .

            2. If labor is at advancing stage  Vaginal delivery with induction of labor (vaginal) may be tried.

        • If mother is stable , fetus is at term & doing well , labor has already started & progress  Vaginal delivery with augmentaion of labor, if necessary.

    Stable mother + away from term : Conservative treatment (rarely needed).

    Uterine rupture

    (Clinical presentation is highly variable and need

    high index of suspicion)

    TTT: delivery by emergency C.S

    • Can be difficult to distinguish from placental abruption (especially when there is history of C.S).

    • Symptoms of uterine ruptured are preceded with: agitation/tachycardia/hyperventilation.

    -- Intense abdominal pain + mild or massive vaginal bleeding

    -- after rupture occurs , slight relieve followed by return of pain may occur -- Vitally : patient usually present with signs of hypovolmic shock !

    -- Presenting part may retract (Loss of fetus station!!) and no longer palpated on pelvix exam / where fetal limbs may easily palpated by abdominal examination. - It's : 1- mostly problem during active labor NOT during antepartum.

    • Risk with low transverse C.S is 1% / with classic vertical C.S 9% 2- If antepartum: usually with history of abdominal trauma.

    Placenta previa

    Abnormal insertion of the placenta on the lower uterine segment near or over cervical os.

    • Presents with: bright red, Painless vaginal bleeding in 3rd trimester (maternal in origin).

    Typically NO uterine tenderness.

    • Treatment if complete: (depends on severity of bleeding & age of pregnancy) :

      1. If stable mother at term  Scheduled C.S

      2. If stable mother not at term  expectant management & may corticosteroids with amniocentesis at 36 weeks  deliver if lung is mature.

    3) In unstable mother + continued bleeding + late deceleration 

    emergency C.S

    Vasa previa

    Rare condition in which the fetal blood vessels traverse the fetal membranes across the lower segment of the uterus between the baby and internal cervical os (velamentous cord insertion).

    Presents with :

    - Painless anterpartum (3rd trimester) /intrapartum hemorrhage (after natural or artificial rupture of membranes "amniotomy" + associated with rapid deterioration of FHR from tachycardia to bradychardia to a sinusoidal pattern (maternal vital signs are normal) : immediately after rupture of membranes, the baseline FHR increases to 160 beats/min.

    and then drop to 70 beats/min. with repeatitve late deceleration.

    The most likely cause of the current condition is : ruptured fetal umbilical vessels.

    • If fetal bleeding is suspected: an Apt test – which differentiate maternal from fetal blood – can be performed to confirm diagnosis.

    • The condition is associated with a high fetal mortality rate "75%" due to fetal exsanguination.

    • Treatment: immediate C.S delivery ("crash-C.S").

    Postpartum problems :

    1 - Postpartum hemorrhage :

    Uterine atony

    Pos-partum hemorrhage at 1st 24 h is : The most common cause 80% is , It's important to make quick diagnosis by palpation of :

        1. Firmness of uterus  Soft "boogy" sensation

        1. Location of uterus  Poorly contracted uterus ( will read that uterine funds is at the umbilicus ).

    • If bleeding is persistent after ttt : other causes should be excluded :

    Cervical & vaginal laceration

    Examine  If any : repair

    Clotting disorder

    • Medical or family history of a clotting disorder.

    • It can be associated with HELLP syndrome / or AF embolism

    Inverted uterus

    1. First step is General supportive measures :

    Fundal or bimanual message / IV / Crystalloid infusion / notification of blood bank

    Oxytocin infusion

    1. N ext most appropriate step in this is  Uterotonic agents : / Carboprost / methylergonovine.

    C.S Hystrectomy

    1- Abnormal adherent placenta 2- Rupture uterus 3- All attempts failed !.

    D & C

    If there is retained placenta :

    - U/S : echogenic mass / Absence of normal endometrial step (less common) - Non-intact placenta on examination.

    Uterine artey embolization

    Or

    Uterine or IIA ligation

    - Vitally stable patient (no excessive bleeding)  failed all attempts , and want to preserve fertility ****alternative to hystrectomy

    Uterine packing

    - Uterine atony is the cause AND Oxytocin is not controlling it

    2- Puerperal infection :

    • Puerperal infection : Woman with a fever greater than 38 C (100.4 F) outside of the first 24 hours postpartum.

    urine analysis & urine culture.

      • Post-Partum UTI : (after 1st 24 – 48 hour postpartum) : ask for

    Uterine tenderness + foul-smelling lochia

      • Postpartum endometritis: ( 2nd – 3rd postpartum day ) with : .

      • Risk factors :

        1. Prolong rupture of membranes (>24 hour),

        2. Prolonged labor ( >12 hours),

        3. C-section

        4. Intrauterine pressure catheters or fetal scalp electrodes.

    Polymicrobial infection

      • The most common cause of this condition is : (gram –ve/+ve, aerobic , anaerobic).

      • The most appropriate therapy is :

    1) Clindamycin (IV) combined with

    2) Gentamicin (IV)

    Chlamydia Trachomatis

    • Most common cause of mucopurulent cervicitis - A common cause of PID

    • Uncommon cause of endometrititis  if it's would be many days after labor not in first 48 – 72 h.

    Group B streptococcal infection

    • Common cause of : endometritis + neonatal sepsis

    • Women screened & ttt before labor for it

    • it's part of the polymicrobial infection

    N.gonorrhea

    Can be a gram –ve of polymicrobial infection in < 10% of cases

    S.aures

    Not commonly isolated

    S.epidermidis

    Can be part of polymicrobial infection

    Reassurance

    • Low grade fever + Leukocytosis + Chills + bloody vaginal discharge ( lochia rubra) " after 2 -3 days discharge become pale and called lochia serosa , then yellow or white and called lochia alba //// IF THERE IS FOUL-SMELL LOCHIA suspect ENDOMETRITITS" are common during first 24 hour of the post-partum period  most appropriate next step is : .

    3- Postpartum DVT :

    • Complaint: A woman , one week postpartum presents with: dull pain in her Lt. or Rt.leg for about 3 days - Physical examination: Swollen , tender , mildly erythematous leg.

    • Doppler: reveals a thrombus in the superficial part of the femoral vein of the left leg (It's called "Superficial femoral vein" BUT it's deep vein)

      Anticoagulation with heparin.

    • The most appropriate next step in management is :

    IVC filters

    - are only indicated in :

    1. patients with recurrent DVT in spite of anticoagulation.

    2. There are contraindications to anticoagulation.

    Thrombolytics

    • Is rarely used for DVT.

    • Occasionally, targeted thrombolytic therapy can be used , BUT it's usually reserved for upper extremity deep venous thrombosis.

    • Pregnancy female G2+P1  with obestatric history of intrapartum placental abruption in previous pregnancy  she received Anti-D immunoglobulin at 28 weeks and immediate post-partum 

    • In her current pregnancy , you decide to determine her antibody titres and it was lifetime membership. 1:34 (>1:16)  the most likely

    explanation of the positive antibody screen (anti-D immunization in this patient) is :

    Low dose of anti-D immunoglobulin postpartum

    • T he qualitative test used to determine presence of feto-maternal hemorrhage is: rosette test.

      • If negative  standard dose of anti-D immunoglobulin should be given

      • If positive the amount of hemorrhage can be evaluated using : - Kleihauer-Betke stain or

        • Fetal red cell stain using flow cytometry

    And the Anti-D imm unoglobulin dose should be corrected accordingly.

    No Prophylaxis early in this pregnancy

    No need for early prophylaxis , because risk of alloimmunization before 28 weeks is low

    Too early administration of Anti-D postpartum

    Too late (after 72 Hour) administration of Anti-D post partum , may result in failure of anti-D immunoglobulin prophylaxis.

    Low dose of Anti-D at 28 weeks of pregnancy

    Standard dose of Anti-D immunoglobulin should be administrated at 28 weeks of uncomplicated pregnany

        • Educational objective :

      • After events associated with excessive feto-maternal hemorrhage (as placental abruption) , the failure to correct the dose of anti-D immunoglobulin may result in maternal alloimmunization.

    ABO Alloimmunization incompatibility :

    O ccur in 1st pregnancy (Primigravida) in contrast to Rh in 2nd pregnancy Patient is missing a blood type , have antibodies to the missing antigens.

    ----

    Mother with blood group O AND Father with blood group AB  will develop baby with blood group either A or B (both differ from mother group )  so resulting in formation of IgG antibodies in the mother wich cross the placenta resulting in "Hemolytic Disease of the Newborn (HDN)" which is :

    Mild disease in most newborns

    ( than Rh factor does)

    Affected infants are asymptomatic in at birth or with absent or mild anemia and develop neonatal jaundice , which is usually successfully treated with phototherapy.

    Urinary Tract infection

    Shorter Urethral length in females than males

    • Most common reason for higher incidence of UTI in female than males are: .

    • Asymptomatic bacteruria :

      • Pregnancy prenatal visit  Asymptomatic & showed in urine culture : clean-catch urine culture >100.000 colony- forming units.(mostly E.Coli)

      • Pregnancy is at risk of developing UTI because enlarged uterus compression resulting in stasis of urine AND Smooth muscle relaxation & ureteral dilatation caused by progesterone.

        Acute Pyelonephritis

      • If It's not treated  The patient is at risk of developing: (in 30 – 40% of cases) , which may cause : 1) Septicemia 2) preterm labor 3) low birth weight babies

      • Treatment : The most appropriate initial pharmacotherapy for this patient is :

    Amoxicillin or Nitrofurantoin or Cephalexin (first generation) for 7 days

    (3 days are nor sufficient).

    Appendicitis in Pregnancy :

        • Presenting with nausea , vomiting , AND MOST COMMONLY: Rt. lower-quadrant pain  change according GA due to upward displacement of appendix.

        • Leukocytosis can be elevated in BOTH : appendicitis & normal pregnancy

    Abdominal U/S

            • The most appropriate next step for diagnosis is : with a graded compression technique  Noncompression & dilatation of appendix are diagnostic.

            • If U/S is not diagnostic: MRI

            • If U/S is not diagnostic & MRI is not available : CT (there is risk on fetus)

            • A diagnostic laparoscopy with laparoscopic appendectomy maybe option BUT

            • Lower, midline vertical laparotomy is a more common procedure, especially when diagnosis is uncertain.

    Anti-phospholipid antibody syndrome :

    Patient with findings suggestive of SLE ( Bilateral malar rash , photosensitivity , hematuria ) + past history of abortions  are at increased risk of subsequent abortions  the main pathophysiological feature for this are:

    SLE autoantibodies ( Lupus anticoagulant + Anti cardiolipin antibodies )

      • Which result in venous thromboembolic events in placenta.

    Amniotic Fluid embolism (AFE):

      • Pregnant female undergone amniocentesis  immediate after procedure she developed :

          1. Loss of conciseness

          2. B reathlessness / Cyanosis + O2 saturation is 75% (Respiratory failure) on 100% O2 flow.

          3. Generalized tonic-clonic seizures.

          4. Hypotension & tachycardia ( cardiogenic shock )

          5. Generalized purpuric rash ( DIC )

    Intubation & mechanical ventilation.

      • The first step in management of AFE is respiratory support  If mask ventilation didn't correct hypoxia , the most appropriate next step is :

    Intravenous fluid

    Once airway is secured & breathing is adequate  IV fluid to correct hypotension.

    LWMH

    Would be an appropriate choice if the patient had pulmonary thromboembolism / BUT this is a scenario of AFE.

    IV Diazepam

    Securing airway & airway should be done first before controlling seizure.

    Intrahepatic cholestasis of pregnancy (ICP) :

    • ICP is a functional disorder of bile formation that develops in the second and third trimesters of pregnancy.

    • The condition is characterized by intense pruritus and increased serum bile acid concentrations.

    • Etiology:

    unclear, but it is thought that genetic & hormonal factors (eg, higher levels of estrogen or progesterone) influence that.

    • Clinical manifestations:

      • intense, intolerable generalized pruritus that is especially significant on palms & soles and worsens at night.

      • Evidence of skin excorations may be present.

      • Jaundice exists in 3rd trimester of pregnancy (in 10-20% of patients).

    • Laboratory evaluation:

      • Serum total bile acids are typically increased and may be the only finding.

      • Liver function studies are suggestive of cholestasis :

    • Diagnosis of ICP by exclusion :

      • It is founded on the presence of pruritus and elevated levels of serum bile acids and/or aminotransferases in the absence of other diseases that could cause such findings. lifetime membership.

    Ursodeoxycholic acid

    • Treatment : is based on Symptom relief & preventing complications in the mother and fetus : is most promising, (as it increases bile flow and can relieve pruritus).

    • Prognosis :

    A) Mother :

        • Good, as the condition resolves shortly after delivery WITH NO hepatic sequelae.

        • It may recur in subsequent pregnancies, and affected women are also at increased risk of developing gallstones.

    B) Fetus :

        • ICP pregnancy poses more danger to the fetus than to the mother, as :

          1. fetal prematurity.

          2. meconium-stained amniotic fluid.

          3. intrauterine demise.

     Therefore, the preferred approach in managing the pregnancies of women with ICP includes an : early delivery once fetal lung maturity is established.

    Complete Blood Count .

    • If non-African descent, with presence of thalasemia anemia in her family is suspected (at risk of hemoglobinopathies that may affect their offspring during pregnancy or after birth) , came for preconception counseling  the most appropriate initial screening test is :

      • If no abnormality is found  No further testing.

      • If there is anemia & reduced MCV  Further testing is required.

    Hb electrophoresis in this patient

    It would be obtained in this patient if the CBC is :

    Anemic + MCV+ Proof of normal iron intake.

    Hb electrophoresis in this patient & her husband

    If offered if an abnormal Hb level is diagnosed in the patient.

    Iron level , TIBC , ferritin level

    If CBC is abnormal , and MCV is decreased  additional testing is required :

    • They are normal in Thalasemia

    • They are abnormal in iron deficiency anemia

    • Pregnant female in 3rd trimester of pregnancy + complaining of dull, low back pain : the pain in minimal in the morning, but increases at the end of the day  the most likely cause of this patient complaint is :

    Increased lumber lordosis

    - The main cause of this pain is : 1- Increased lumber lordosis

    2- Relaxation of the ligaments supporting the sacroiliac and other joints of the pelvic girdle  due to hormonal factors

    • Mitral stenosis is classically presents during pregnancy due to increase blood volume most commonly due to Rheumatic Heart disease.

    Cervical Incompetence (C.I) :

    • Risk factors :

      1. LEEP

      2. Multiple gestation

      3. DES exposure

      4. Previous history of pre-term birth.

    1. Previous history of 2nd trimester pregnancy loss

  • On pelvic examination , the cervix is closed but shorter than normal  most appropriate next step in management is :

    2. Performing Elective cervical cerclage  at 13 – 16 weeks.

    Hypothyroidism :

    levothyroxine dose is increased

    • In most hypothyroid patients who become pregnant , (mostly during 1st trimester).

    • Total T3 , T4 are elevated in pregnancy because of an increase in Thyroid Binding Globulin (TBG) levels.

      • TSH level is checked :

        1. Before pregnancy  if TSH is normal : NO need to increase the levothyroxine dosage before pregnancy.

        2. During pregnancy  TSH is checked more frequent during pregnancy , usually 2 – 3 months.

      • The requirements for L-Thyroxine in patient receiving Estrogen Replacement Therapy (ERT) in increased.

    Causes :

        1. Increased metabolism of thyroid hormones due to induction of P450 (CYP3A4) in liver.

        2. Increased level if thyroid-binding globulin (TBG).

        3. Increased volume of distribution of thyroid hormones

    • Thyroid function tests :

    - Thyroid function during pregnancy is affected by 2 mechanisms :

    1. Increase in thyroid binding globulin (TBG) concentration :

      •  circulating estrogen during pregnancy   in production of TBG  result in an increase in the TBG-bound

    total T3 & T4 / Normal free T3 , T4 / normal TSH

    T3 & T4  as a result ,  TBG leads to : .

    1. Stimulation of TSH receptor by chorionic gonadotropin (hCG) :

      • The elevated level of hCG in pregnancy can also cause a mild stimulation of the TSH receptor  resulting in a small  in free T3 & T4 , and normal TSH (mild  in 10-20%).

    • Infants born to patient with Grave's disease treated with surgery are at risk for thyrotoxicosis because of :

    persistent

    Thyroid Stimulating Immunogobulin (TSI) in the mother.

    Passage of the

    Epidural anesthesia side effects :

    Blood venous pooling

      1. Sympathetic block  V.D of lower extremity vessels (not upper trunk)  decrease cardiac output Hypotension ( in 10% of cases).

      1. Urinary retention : caused by bladder denervation.

        • This incontinence is only transient and lasts until the effect of the anesthetic wears off and the bladder regains normal function.

        • Abdominal examination: soft, non tender abdomen (distended bladder).

        • Post void residual urine volumes are : high (OVERFLOW INCONT.)  e.g.: 400 ml.

          intermittent “in and out “ catheterizations

        • The most appropriate treatment for her incontinence is:

    until the pt is able to void on her own.

    • False labor contractions :

      • Start in last 4 – 8 weeks of pregnancy

      • Occurs in lower abdomen + irregular + No shortening interval + No increase in intensity ( may regular and increase in intensity in last month) + MOST IMPORTANT IN FALSE LABR : closed cervix (NO progressive cervical changes) + relieve by sedation.

    • S imple(risk 8%) or complex(29%) endometrial hyperplasia WITH atypia  TTT is Hystrectomy if no desired future fertility/ BUT if desired fertility  cyclic progestin with 3-6 month biopsy.

    Low dose OCP  appropriate for prevention of hyperplasia in anovulatory conditions (PCO) "not sufficient if occurred"

    Tamoxifen

    Raloxifene

    Tamoxifen  Exaggerate menopausal symptoms EXCEPT: it  osteoporosis risk +  cardiovascular risk.

    It's first line agent for prevention of osteoporosis (even more effective than biphosphonates)

    - Increase risk of Endometrial cancer (agonist effect) - Increase risk of thromboembolism.

    • DON'T increase risk of Endometrial cancer.

    • Increase risk of thromboembolism So,

    Contraindicated If there is a history of DVT.

    repeat pap smear (cytology) in 1 year

    Cervical cancer screening : Women age 21-24 years with : ASC-US OR LSIL.

    In those young age :

    • HPV infection is transient &

    • Malignant transformation is rare.

    HOWEVER , colposcopy is recommended for any :

    1. ASC-H .

    2. Atypical glandular cells.

    3. HSIL.

     Thus colposcopy is not performed unless the patient : demonstrates ASC on 3 consecutive Pap smears.

    HPV DNA testing

    Routine Cervical Cancer Screening : guidelines recommend

    1. In women 21 – 29 years :

      • Cytology every 3 years .

    1. In Women >= 30 years :

      • Cytology every 3 years OR

      • Combination of Cytology + Pap DNA testing every 5 years.

    Women age >=25 years with : ASC-US is recommended.

    - This help triage high-risk HPV-positive patients and leads to fewer colposcopies :

    • If HPV is positive : colposcopy will be required.

    High grade Squamous Intraepithelial Lesions (HSIL) diagnosed by Pap smear during pregnancy

    • The management of any women with "HSIL" is Colposcopy & directed biopsy ( The aim of colposcopy during pregnancy is to exclude Invasive cervical cancer) :

    Repeat colposcopy & biopsy 6-8 weeks after delivery.

      • If directed biopsy is negative the best next step is :

    LEEP (excisional procedur

    Repeat Pap smear

    Repeating pap smear will not change management of the patient  a repeat colposcopy is still required after delivery.

    V aginal cancer :

    • Squamous cell carcinoma  is the most common form of vaginal cancer.

    • Risk increase with age (mostly >60 years).

    • Most common symptoms : vaginal bleeding & malodorous vaginal discharge.

    • Definitive diagnosis is made by: biopsy.

    • Treatment (depends on staging) :

      • Stage I & II ( no extension to the pelvic wall and no metastases ) :

        • if tumor less than 2 cm in size  may removed surgically

          radiotherapy

        • if tumor more than 2 cm in size  treated by .

    The point in some questions is that patient may present with very old age & co-morbid conditions (poor surgical candidate) even if < 2 cm Radiation alone is sufficient.

      • Stage III & IV & tumors > 4 cm :

    Bilateral solid ovarian masses discovered incidentally in a multiparius African-American pregnant woman most likely signify a pregnancy luteoma. This is a benign self-limited condition and requires no treatment.

    If US shows unilateral solid: do a laparotomy or laparoscopic biopsy to rule out malignancy.

    Adenomyosis :

    • Typically multiparous woman < 40 year old.

    Other symptoms: hematochezia / hematuria / premenstrual or postmenstrual spotting.

    • Examination: * Tender posterior vaginal fornex (rectovaginal tenderness)

        • Tenderness on motion of uterus ( due to presence of ectopic endometrial tissue ).

        • Tender adenxal mass /or firm nodularity in broad ligaments / uterosacral ligament in cul-de-sac.

    • Ultrasound: may demonstrate homogenous endomterioma on ovary (DON'T confuse if there is fertility + ovarian mass)

    5- Breast cancer.

    reexamination

    • A young woman who presents with a breast lump can be : asked to return after her menstrual period for (which may reveal regression of the mass) if no obvious signs of malignancy are present.

    Breast engorgement :

    • is common in the first 24 to 72 hours after childbirth secondary to milk accumulation / peaks 3-5 days postpartum and improves spontaneously in most patients.

    • Complaints: feel breast fullness, tenderness and warmth.

    • Treatment (symptom control): you can do cool compresses, acetaminophen, NSAIDS.

    Mastitis

    • Cellulitis of the periglandular tissue caused by nipple trauma from breast-feeding coupled with introduction of S. aureus from the infant’s nostrils into the nipple ducts.

    • Symptoms : often begin 2–4 weeks postpartum;

    • Examination: unilateral; and include focal breast tenderness, erythema, edema, warmth, and possible purulent nipple drainage.

    • Differentiate from simple breast engorgement :

     Infection is suggested by focal symptoms, a breast milk culture, ↑ WBC count, and fever.

    - Treatment:

    • Continued breast-feeding & PO antibiotics (e.g., penicillin, dicloxacillin, erythromycin).

    • Incision and drainage of breast abscess if present.

    Breast abscess

    - Similar to mastitis BUT: with a palpable, flactuant mass . - Treatment: Incision & drainage + antibiotics.

    Plugged ducts

    • Similar to mastitis BUT: lack fever or systemic symptoms.

    • Treatment: They are treated by improving the quality of breastfeeding.

    Persistently plugged ducts resulting in galactocele may be treated with aspiration.

    Superficial vein thrombosis

    Cause: tenderness & localized erythema BUT : is unlikely to cause bilateral tense breasts.

    Menstrual Physiology & disorders :

    • Initial menstrual cycles in pubertal females (first 1 – 2 years) are anovulatory :

    They are irregular and may with menorrhagia ( prolonged or heavy menstruation, typically lasting longer than 7 days or exceeding 80 mL ).

    Anovulation

     The most likely cause of her symptoms is: .

    This is due to immaturity of the developing hypothalamic-pituitary-gonadal axis, that does not produce adequate quantities and proportions of the hormones (i.e. FSH and LH) required to induce ovulation.

    Bleeding disorders (coagluopathies)

    Result in: unusually heavy menses (not irregular) that may frequently require blood transfusion.

    • Midcylce pain (mittleschmerz) :

      • Abdominal pain in a young female with regular menstrual periods (not taking OCPs = ovulating), in the

    middle of her cycle (LMP was2 weeks ago ) with a benign history and clinical examination is most likely :

      • Lower abdominal pain radiating to the thighs & back, begins hours before menstruation = 1ry dysmenorrhea.

      • It is caused by increased levels of prostaglandins

      • Treatment :

        1. NSAIDs are the most effective for treatment;

        2. Oral contraceptive pills inhibit ovulation and are also effective.

    • Luteal phase defect

      • Luteal phase defect is confirmed by endometrial biopsy.

      • Luteal phase defect is first attempted with progesterone supplements.

      • Clomiphene citrate or hMG can be tried if progesterone gives no results.

     Clomiphene citrate (estrogen analogue) acts by binding to hypothalamic estrogen receptors and suppressing the inhibitory effect estrogen has on GnRH production.

      • Major complication of ovulation induction are:

          1. Multiple gestation

          2. OHSS (ovarian hyperstimulation syndrome):

    • Atrophic Vaginitis : - Clinical Diagnosis , typically : Vaginal Dryness , Dyspareunia , Dysuria , Pruritis, Urinary frequeucny.

      • Examination: pale , dry , smooth vaginal epithelium , scarce pubic hair , loss of labial fat bad.

      • Differential Diagnosis: many symptoms can also be seen in UTI IF Urine dipstick is normal rules out UTI.

      • Treatments:

              1. First step in management in mild atrophic vaginitis vaginal lubricants.

                Vaginal Estrogen Replacement.

                Contraceptive pills :

              2. First step in management in Severe atrophic vaginitis 

      • Even though OCPs may worsen diabetes they do not precipitate diabetes in a non-diabetic patient.

    they will worsen patient's hypertension.

      • OCPs are steroid compounds  therefore cause Na & water retention; 

    reassurance

      • Weight gain is not a side effect of combined OCP  .

    BUT  weight gain have been reported with use of medroxyprogesterone use ( so, don't switch OCPs to it)

      • As for breast cancer, the risk does not seem to change with their use.

    • Postpartum contraceptions :

      • Contraceptive methods than can be used in postpartum period include :

        1. Progetin-only contraceptives : preferred in lactating women ( + no DVT complications of combined pills)

        2. Sterlization (tubal ligation) : Not preferred if mentioned she only need contraception for short time NOT perminant !

        3. Barrier methods.

        4. IUD.

    • Emergency contraceptive :

      Levonorgestrel

      •  is the recommended method up to 120 hour after intercourse.

    Prostaglandin E2 suppository is used as 2nd trimester abortifacient

    Infertility :

    • Infertile young female with :

        • History of stressful life , excessive exercise , eating disorders.

        • Failure to conceive.

        • Irregular menses or 2ry amenorrhea.

        • FSH & LH are both decreased

          • This suggest diagnosis of hypogondaotropic Hypogonadism : hypothalamic dysfunction with insufficient

    Pulsatile GnRH release   FSH , LH

    Decreased bone mineral density.

          • The patient is at great risk for : (osteoporosis)

            Pulsatile GnRH release.

          • Treatment : 1) First line is to cut down the stress 2) If this failed , the next management step is :

    Hysterosalpingogram

     So, testing of ovulation by : mid-luteal phase progesterone / serum prolactin level / Serum testosterone / serum inhibin B Is not likely to identify the cause of infertility ,,, so the most appropriate next step is : .

    Serum inhibin B : is used to determine ovulatory reserve. It will be decreased in older women who have a decreased capacity to ovulate.

      • I nability to conceive after > 1 year of frequent intercourse. (for those >35)  definition of infertility is shortened to >6 months).

    semen analysis

      • The best initial next step in management of a couples with infertility is : as initial screening test.

      • After excluding male factors of infertility (20-30%)  then go ahead for female evaluation !

    • Female , infertile , with a strong desire to get pregnant  may result in some hormonal changes mimicking those of pregnancy : Amenorrhea / enlargement of breasts & abdomen / morning sickness / weight gain / sensation of fetal movement / reported +ve pregnancy test ( but at office will be –ve)

      pseudocyesis

      • The most likely diagnosis is : a form of conversion disorder & need psychiatric evaluation.

    Polycystic Ovary Syndrome :

      • Presence of any 2 of the following 3 signs & symptoms :

        1. Clinical ( i.e hirsuitism , acne , male pattern baldness "androgenic alopecia") AND/Or Biochemical ( i.e. hight serum androgen , increase LH/FSH ratio)

        2. Amnorrhea or oligomenorrhea

        3. Pelvic U/S with cystic ovaries (small cysts are noted around the ovaries in a classic " string of pearls" appearance.

    2h oral glucose tolerance test (OGTT):

      • All patients with clinical symptoms suggestive of PCOS, is recommended to have :

     2 hour glucose > 140  presumptive of Impaired glucose tolerance (insulin resistence)  2 hour glucose > 200  consistent with diabetes mellitus type II.

    Metformin

      • Any women with PCOS & impaired glucose tolerance  The following is indicated: Which has following benefits :

            1. Helps preventing DM type II

            2. Helps losing weight (most PCOS are obese)

            3. In conjugation with clomiphene citrate, it helps to induce ovulation ( however not FDA approved just for this purpose.

            4. It has modest effect on suppression androgen production thus help correcting hirsuitism. - PCOs at increased risk of:

            1. 50% are obese.

            2. Insulin resistence & DM type II 3- Cardiovascular disease.

    4- Endometrial cancer ( monitoring of CA-125 used to monitor therapy for ovarian cancer NOT endometrial) - Treatment of :

    Clomiphene Citrate

    Infertility : Because ovaries are functional  the most appropriate therapy is: +- Metformin.

    (because:lower vagina originates from urogenital sinus).

    • Karyotype: female (46, XX) Phenotype: Female

    • Serum testosterone levels: are in range typical for females.

    - Treatment :

    These patients should be treated with :

    surgical elongation of the vagina.

    - The combination of :

    1. primary amenorrhea,

    2. bilateral inguinal masses,

    3. normal breast development (why? Because testes secret some

    estrogen, unopposed to testosterone)

    WITHOUT pubic or axillary hair.

    • Irregular menstrual cycles in women shortly after menarch :

    Insufficient gonadotropin secretion

        • Young female with her menses has just started BUT it's irregular (anovulatory) + administration of progesterone results in withdrawal bleeding in 3 days (menses after progesterone chalange)  the most likely explination for her irregular menses is :

        • This is due to immaturity of the developing H-P-G axis that doesn't produce adequate quantities of the hormones FSH & LH required to induce ovulation.

        • In absence of ovulation ( which results in Corpus Luteum formation progesterone production which maintain endometrium ) , the endometrium builds up under influence of estrogen , but without influence of progesterone , the cue to slough endomterium is lacking and menstrual-like bleeding occurs due to estrogen breakthrough bleeding.

    Marked estrogen deficiency

    Menses due to progesterone challenge wouldn't occur in the setting of estrogen deficiency as estrogen is required to build up endometrium.

    Metformin

    Promote ovulation in PCOS , as insulin resistance affect normal ovulation.

    GnRH agonist

    • Pulsatile form  induce ovulation ( need ovulatory reserve )

    • Chronic therapy  suppress ovulation

    Progesterone

    Correct : Luteal phase defect .

    • Anovulation secondary to Morbid Obesity :

      • Female , with morbid obesity , is complaining of irregular menses followed by amnorrhea (e.g for 9 month) with :

          • Serum TSH , prolactin normal

          • FSH , LH  normal

    The ovaries are still producing estrogen , BUT progesterone is not being produced at normal post ovulation levels  therefore, progesterone withdrawal menses at the end of the cycle doesn't occur.

    Menopause

    • Defined as 1 year of no menses (not 9 month).

    • FSH , LH are 

    Pituitary dysfunction

    - FSH , LH are  (< 5mIU/mL)

    Premature Ovarian Failure

    • Occur in women < 40 year old.

    Post-tubal ligation syndrome

    • Dysmenorrhea / heavy bleeding or spotting / changes in length or regularity of menstrual cycle.

    • Long periods of amenorrhea is not usually reported !

    Estrogen deficiency.

    • Secondary amenorrhea in athlete female :

      • A marathon runner female presents with 2ry amenorrhea  most likely etiology is :

          • In female athletes, there is a relative caloric deficiency secondary to in adequate nutritional intake as compared to the amount of energy expended.

          • Women with this condition is have shown to have  level of LH , GnRH  resulting in estrogen deficiency

     So, these women at increased risk of all conditions associated with estrogen deficiency, including:

    infertility , vaginal atrophy , breast atrophy , osteopenia.

    • Hyperprolactinemia :

    Prolactin production is :

      • Stimulated by : serotonin & TRH(TRH is increased in 1ry hypothyroidism Prolactin  amenorrhea & galactorrhea) .

      • Inhibited by : dopamine.

    Riseperidone side effects :

      • It's dopamine & serotonin antagonist that can cause: weight gain / hyperprolactinemia  which leads to

    amenorrhea & galactorrhea.

    Galactorrhea :

    1- Bilateral nipple discharge that is : Clear / Milky / yellow/brown/green discharge.

    The most appropriate next step in management is :

    AND possible MRI of the brain to rule out prolactinoma.

     Another most common cause of bilateral nipple discharge is pregnancy  FIRST , you exclude it if mentioned in the question that LMP was about one week ago lifetime membership. then look for the cause :

    - Causes :

    a- Prolactinoma, b- Hypothyroidism c- Overstimulation of the nipple d- OCPs e- medications which lower dopamine levels are common causes of galactorrhea.

    Mammography

    Used for both :

    1. Screening breast cancer

    2. Evaluation certain cases of breast lump & discharge  it would be indicated if :

      • Breast lump

      • positive guaiac or grossly bloody nipple discharge.

    U/S

    Is one test can be used to evaluate a breast mass , useful at :

    1. discerning fluid-filled masses from solid masses.

    2. Evaluating the dense breast tissue of the younger women.

    3. In guided biopsies.

    It's not a part of the work-up for galactorrhea.

    Cytological examination

    Indicated in : Uniductal & guaiac positive nipple discharge Not indicated in guaiac negative discharge.

    Surgical Evaluation

    Would be indicated in this patient if she had :

    • Breast lump

    • positive guaiac or grossly bloody nipple discharge.

    • Lactation suppression :

      Tight fitting bra & ice packs & avoid stimulation of

      nipples & analgesics to control pain.

      • Female just delivered  with death of her fetus  breast engorgement (warm , firm , tender to palpation)  the following is the most appropriate next step in management:

    NO ROLE OF MEDICATIONS IN SUPRESSION OF BREAT MILD PRODUCTION

    Frequent emptying of breast

    Will only maintain mild production  make condition worse

    Estrogen therapy

    Used in past for mild suppression  risk of thromboembolism

    Bromocryptine

    Was commonly used BUT not longer FDA approved because of side effects

    • Age-related decrease ovarian reserve :

      decreased ovarian reserve.

      • The most common cause of decreased fertility in women in their 4th decade who are still experiencing menstrual cycles (to exclude premature ovarian failure which is 2ry amenorrhea before 40 years) is
