Clinical teaching and practical ideas for your next study session.
Before Methotrexate: Is the Adnexal Finding Really Ectopic?
An empty uterus, a slow β-hCG rise, and an adnexal finding raise concern—but do they establish ectopic pregnancy? Learn what evidence should guide the next step before methotrexate.
POI Etiology Workup After Diagnosis: How to Handle the Four-Lab SAQ When TSH and TPO Differ
A four-lab POI SAQ tests whether you can separate diagnosis from causation. Learn the current core workup, the TSH-versus-TPO trap, and a focused retrieval exercise.
OHSS Hospitalization: Why Hypotension and Hemoconcentration Matter More Than Ovarian Size
The admission decision in ovarian hyperstimulation syndrome is driven less by ovarian diameter than by effective circulating volume, organ function, symptom control, and the safety of outpatient monitoring. Learn why hypotension, tachycardia, hemoconcentration, oliguria, and respiratory compromise change disposition.
An 80-CGG-Repeat FMR1 Result at 11 Weeks: Choose the Test That Answers the Right Question
An increased nuchal translucency and a family history suggestive of Fragile X create two separate diagnostic questions. This case discussion shows why cfDNA cannot answer the FMR1 question and how to choose between CVS and amniocentesis while evaluating the NT finding in parallel.
Lisinopril in Pregnancy: Stop the Drug, Not the Blood-Pressure Plan
When pregnancy is recognized during lisinopril therapy, separate three decisions: stop ongoing ACE-inhibitor exposure, preserve maternal blood-pressure control, and interpret fetal risk according to gestational timing.
Raloxifene for Osteopenia: Why “Estrogen-Like in Bone” Does Not Mean Menopause Treatment
A T-score of -1.8 is osteopenia, not an automatic indication for medication. Learn why raloxifene preserves bone and reduces vertebral fracture risk without providing hot-flash relief or causing clinically important endometrial stimulation—and how that should guide patient selection.
At 8 Weeks After a Prior Neural Tube Defect Pregnancy: What Can Still Change?
A first prenatal visit after a prior myelomeningocele requires separating the folic-acid prevention window that may have passed from still-actionable care for chronic hypertension, obesity, dating, and fetal surveillance.
PCOS and Endometrial Cancer: When Protection, Not Screening, Is the Board Answer
The board-ready PCOS distinction is not simply increased cancer risk. It is recognizing chronic anovulation, absent progesterone, endometrial proliferation, and when protection—not routine screening—is the next move.
Emergency Contraception by the Clock: How Ovulation Timing Chooses LNG, UPA, or the Copper IUD
Emergency contraception is not one mechanism in three interchangeable options. The decisive board-level question is how close the patient is to ovulation—and whether an oral method can still delay it or the patient needs a method that acts independently of ovarian suppression.
When the Parent Answers: A Board-Ready Case in Adolescent Contraception, Confidentiality, STI Screening, and HPV Vaccination
A practical case discussion on adolescent confidentiality, coercion-sensitive contraceptive counseling, STI screening, and HPV vaccination.
ADAMTS13 First: A Board-Ready Approach to TTP, HELLP, and Pregnancy-Associated TMA
When severe thrombocytopenia and hemolysis appear in pregnancy, use a syndrome-first algorithm, ADAMTS13 intelligently, and targeted retrieval practice to separate TTP from HELLP and complement-mediated TMA.
When Thrombocytopenia and Hemolysis Are Not HELLP: Distinguishing TTP, aHUS, and Severe Preeclampsia in Pregnancy
A practical, mechanism-based approach to pregnancy-associated thrombotic microangiopathy, with emphasis on ADAMTS13, renal injury, delivery response, and urgent management.
