Exam 4 - Chapter 18 Flashcards
Pelvic Inflammatory Disease (PID/Salpingitis)
Inflammation of the fallopian tubes, with ovaries at times
Causes: Chlamydia trachomatis (subacute), Neisseria gonorrhoeae (acute), Gardnerella vaginalis, and Trichomonas vaginalis. Occurs in young sexually active women with many partners
Pathology: Edematous tubal serosa, collection of pus forms pyosalpinx, degrading pus forms hydrosalpinx
Symptoms: High fever, lower abdominal pain, cervical motion tenderness, future ectopic pregnancy, infertility
Treatment: Antibiotics
Ectopic Pregnancy
Implantation of the ovum in the fallopian tube
Symptoms: Missed period, other signs of early pregnancy, vaginal bleeding 6 -8 weeks after last period. Upon rupture, bleeding may be excessive Lower abdominal pain may be: • Sharp unilateral • Constant • Diffuse or localized – May be referred to shoulder
Abdominal pain or unexplained hypovolemia + woman of child-bearing age = Ectopic pregnancy
Diethylstilbestrol (DES)
- Known as super-estrogen
- Nonsteroidal estrogens used from 1946–1970 to treat mothers who were prone to spontaneous abortion
- Disorders in daughters of women who received diethylstilbestrol (DES) therapy during pregnancy.
- Precocious Puberty: Puberty before the specified age
- Clear cell adenocarcinoma of the cervix and vaginal adenosis (benign condition characterized by mucosal columnar epithelium-lined changes) in areas normally lined by stratified squamous epithelium (metaplasia), may also occur in these patients
Placental Accreta
Deep penetration of the placental villi into the wall of uterus
Causes: Predisposed by previous C-section scars or endometrial inflammation
Pathology: Defective decidual layer allows placenta to attach directly to myometrium
Symptoms: Massive hemorrhage after delivery
Treatment: Hysterectomy to stop bleeding
Placental Previa
Implantation of the zygote in the lower section of the uterus
Causes: Predisposed by previous C-section scars
Pathology: Attachment of placenta to lower uterine segment of cervix
Symptoms: Painless bleeding, premature labor
Treatment: C-section, bed rest
Abruptio Placentae
Partial/complete premature separation of the placenta which is an obstetric emergency for mother and fetus
Causes: DIC, smoking, cocaine, hypertension
Pathology: Premature separation of the placenta
Symptoms: Painful bleeding with abdominal pain in third trimester. Can result in fetal death
Treatment: Immediate delivary & control bleeding
Abortion
Termination of pregnancy before the 22nd week of gestation
Causes: By physician or RU-486
Symptoms: Cramping, abdominal pain, backache, and vaginal bleeding
RU-486
RU-486 or Mifepristone competes with progesterone for the progesterone receptors.
• Mechanism of action: Without progesterone, the lining of the women’s uterus breaks down and sheds like normal menstrual cycle. In addition, the drug opens the cervix and influence contractions with help of prostaglandin to dislodge and expel the embryo. Ru-486 works only during the first 9 weeks of pregnancy, or up to 63 days from the start of the women’s last menstrual period. After this time, the level of progesterone goes up in a higher level where RU-486 is not effective
Complete Abortion
Spontaneous expulsion of all fetal and placental tissue from uterus prior to 20 weeks gestation. Cervix closed on examination
No further intervention necessary; ultrasound to confirm an empty uterus may be helpful
Incomplete Abortion
Passage of some fetal or placental tissue, but not all, prior to 20 weeks gestation. Cervix dilated on examination
IV hydration, type and screen/cross, immediate suction curettage
Threatened Abortion
Uterine bleeding prior to 20 weeks gestation, without any cervical dilation or effacement
Ultrasound to document fetal viability; modified activity and pelvic rest until bleeding stops
Inevitable Abortion
Uterine bleeding prior to 20 weeks gestation, accompanied by cervical dilation, but no expulsion of fetal or placental tissue through cervical os
Expectant management or evacuation of pregnancy (surgical or medical termination)
Missed Abortion
Fetal death before 20 weeks gestation without expulsion of any fetal or maternal tissue for at least 8 weeks thereafter
Suction curettage or medical termination of pregnancy
Septic Abortion
Any of the abortions above, accompanied by uterine infection
IV antibiotics, followed by suction curettage
Gestational Trophoblastic Disease
Hydatidiform mole (placental abnormality): swelling of the chorionic villi (grapelike clusters). Uterus expands as if a normal pregnancy is present, but the uterus is much larger
Causes: Chromsomal abnormalities
Pathology: Β-hCG much higher than expected for date of gestation. Classically presents in the second trimester as passage of grape-like masses through the vaginal canal. Honeycombed uterus appearance
Diagnosis: Routine ultrasound in the early first trimester. Fetal heart sounds are absent, and a ‘snowstorm’ appearance is classically seen on ultrasound
Two types:
Complete mole: Fetus can not be identified in the ammnotic fluid due to production of androgen. No maternal chromosome only paternal chromosome (46, XX)
Incomplete mole: Some the fetal parts are present. Two sperm fertilize one egg making triploid (69, XXY)
Treatment: Most abort spontaneously, or D&C
Gestational Choriocarcinoma
Malignant tumors of germ cells of the placenta. Rare
Causes: 50% develops from hydatidiform mole, 25% develops from placental cells after abortion and 25%, develops from normal placenta
Pathology: High levels of hCG, necrotic tumor
Symptoms: Excessive vaginal bleeding after removal of mole or delivery of fetus/abortant. Hemoptysis
Treatment: Surgery, chemo
Toxemia of Pregnancy (Preeclampsia and Eclampsia)
This disorder is characterized by severe hypertension that most often occurs de novo during pregnancy or complicates preexisting hypertensive disease. Toxemia characteristically occurs during the third trimester, most often in the first pregnancy
Preeclampsia: Triad of hypertension, edema, and proteinuria during the 3rd trimester. HELLP syndrome (Hemolysis, Elevated Liver enzymes, and Low Platelets)
Eclampsia: all of the above plus seizures
Treatment:
Preeclampsia: Delivery of the fetus, bed rest, treat hypertension
Eclampsia: Medical emergency, treat with magnesium sulfate and diazepam (anti-epileptics)
Supine Hypotensive Syndrome
- Uterus compresses inferior vena cava
- Venous return to heart decreases
- Decreased venous return leads to decreased
cardiac output - BP decreases
Treatment: Place patient on left side to restore venous return
Menorrhagia
Prolonged (>7 days) and or heavy (≥80ml) uterine bleeding occurring at regular intervals
Metrorrhagia
Variable amounts of inter-menstrual bleeding occurring at irregular but frequent intervals
Polymenorrhea
An abnormally short interval (
Oligomenorrhea
An abnormally short interval (
