Read, then practice
- Mendelian inheritanceWhen both unaffected parents carry a pathogenic variant for the same autosomal recessive disorder, each pregnancy has a 25% chance of being affected. Recurrence risk is independent across pregnancies.Free chapter
- Pulmonary embolismIn pregnant patients with suspected pulmonary embolism, no signs of DVT, and a normal chest x-ray, a ventilation-perfusion scan is the preferred imaging test; CT pulmonary angiography is used when the chest x-ray is abnormal.Free chapter
- Antepartum hemorrhageIn a patient with painless third-trimester bleeding and unknown placental location, localize the placenta with ultrasonography before performing a digital cervical examination.Free chapter
- Hypertensive disorders of pregnancyEclampsia is treated with intravenous magnesium sulfate (to stop and prevent seizures) plus urgent control of severe-range blood pressure, followed by delivery once the mother is stabilized.Free chapter
- Prenatal careNeural tube closure occurs early enough that folic acid should be started before conception. A prior neural tube defect–affected pregnancy warrants high-dose folic acid because folate-dependent one-carbon transfer supports nucleotide synthesis during early embryonic development.Free chapter
- Teratology and drugs in pregnancyUse a preductal–postductal oxygen saturation difference and echocardiographic evidence of elevated pulmonary pressure with right-to-left shunting to recognize persistent pulmonary hypertension of the newborn. Late-pregnancy SSRI exposure is a risk factor, not diagnostic proof.Free chapter
