Study Notes

Miscarriage

May occur after 13 weeks of pregnancy, with the fetus being expelled from the uterus
Placenta may be partially or completely retained in the uterus, leading to incomplete miscarriage
Symptoms include bleeding, cramping, and pain, which can be similar to an early abortion but may be more severe
Causes include genetic, uterine, or hormonal abnormalities, infections, and tissue rejection
Most miscarriages happen in the first trimester, often due to chromosomal abnormalities in the embryo
Genetic problems in the parents can contribute to miscarriages, especially in cases of repeated miscarriages or family history of birth defects
Progesterone deficiency can also be a cause, and supplementation may be prescribed for women with low progesterone levels
Second trimester miscarriages can be caused by uterine malformations, fibroids, cervical problems, and issues with the umbilical cord or placenta
Exercise, especially prolonged exercise, has been linked to an increased risk of miscarriage before 18 weeks
High caffeine consumption has also been associated with miscarriage, but the link is not statistically significant in every case
While sexual intercourse during the first trimester is often believed to cause miscarriage, this has not been proven
Cocaine use, physical trauma, environmental toxins, and the use of an IUD during conception can increase the risk of miscarriage
Certain antidepressants, such as paroxetine and venlafaxine, can also lead to miscarriage
Miscarriages are diagnosed using ultrasound and examination of expelled tissue, with chromosomal abnormalities being found in about half of miscarriages
Genetic testing of both parents may be recommended in cases of multiple miscarriages
A threatened miscarriage refers to bleeding during pregnancy before viability, where the fetus may still be viable
Incomplete abortion involves the expulsion of part of the fetus, with the remaining parts still inside the uterus
Complete abortion is the expulsion of the entire fetus
An empty sac is a condition where the gestational sac develops, but the embryo is absent or stops growing early
An inevitable miscarriage occurs when the cervix dilates, but the fetus is not yet expelled
Missed miscarriage is when the embryo or fetus dies but the miscarriage has not occurred yet
Treatment for retained products of conception includes misoprostol administration, inpatient observation, and potential surgical evacuation

Ectopic Pregnancy

Occurs when the fertilized egg implants outside the uterine cavity
Most ectopic pregnancies happen in the fallopian tube (tubal pregnancies)
Can also implant in the cervix, ovaries, and abdomen
Ectopic pregnancies are a medical emergency and can lead to death if not treated
Risk factors include pelvic inflammatory disease (PID), infertility, use of intrauterine devices (IUDs), exposure to DES, tubal surgery, intrauterine surgery, smoking, previous ectopic pregnancies, and tubal ligation
Cilial damage and tubal occlusion caused by PID can increase the risk of ectopic pregnancy
Tubal surgery can also increase the risk
Intrauterine adhesions (IUA) can lead to ectopic cervical or tubal pregnancies
Tubal reversal after sterilization carries an increased risk of ectopic pregnancy
History of ectopic pregnancy increases the risk of future occurrences
Smoking and vaginal douching are suspected to contribute to ectopic pregnancy risk
Women exposed to diethylstilbestrol (DES) in utero have an elevated risk of ectopic pregnancy
Low socioeconomic status may be a risk factor for ectopic pregnancy
Diagnosis involves considering ectopic pregnancy as a possible cause of abdominal pain or vaginal bleeding in pregnant women
Ultrasound showing a gestational sac with fetal heart in the fallopian tube is a clear indication
Abnormal rises in β-hCG levels may also suggest ectopic pregnancy
Transvaginal ultrasound is the most effective test
An adnexal mass in the absence of an intrauterine pregnancy on transvaginal sonography highly suggests ectopic pregnancy
An empty uterus with high β-hCG levels may be indicative of ectopic pregnancy
Repeat blood work and ultrasound may be necessary if the diagnosis is uncertain
Laparoscopy or laparotomy can visually confirm the diagnosis, but it may be challenging to find the pregnancy tissue if a tubal abortion or rupture has occurred
Culdocentesis, a test involving the retrieval of fluid from the space between the vagina and rectum, can be used to detect internal bleeding

Ectopic Pregnancy Treatment

Medical treatment with methotrexate is a viable alternative to surgery, especially in early pregnancy
Methotrexate terminates the growth of the embryo
Contraindications include liver, kidney, or blood disease, and an ectopic embryonic mass exceeding 3.5 cm
