What's included in this guide:

Case Sheet

• Full history with "WHY" for every question asked - the reason behind each question, not just what to ask
• Positive and negative history with clinical significance
• Each symptom tied to its pathophysiological basis in twin pregnancy

History Taking Highlights

• Why fundal height > dates: Two fetuses + two placentas + polyhydramnios
• Why ask about ART/ovulation induction: DZ twinning mechanism - superovulation
• Why MZ rate is constant: Not influenced by age/parity/ART - spontaneous splitting
• Why advanced maternal age increases DZ twins: Elevated basal FSH → multi-follicular recruitment

Examination Procedure

• Step-by-step Leopold's maneuvers with interpretation for twins specifically
• Normal vs. abnormal fundal heights at each gestational age with twin-specific expected values
• Two FHRs - how to confirm and differentiate from same heart at two locations

Investigation Values

• Every investigation with normal range, abnormal range, and specific significance in twin pregnancy
• USG findings (Lambda sign, T-sign, chorionicity markers)
• Quintero staging for TTTS

Summary + Diagnosis

• Model summary statement (fill-in format)
• Differential diagnosis table with how to distinguish each

Case Discussion

• Maternal complications - each with mechanism and incidence
• TTTS pathophysiology and Quintero staging in detail
• Management by chorionicity type

Investigations and Management
