What is the specific key diagnostic feature of Esophageal Eosinophilia?
Biopsy showing >15 eosinophils per high power field in the esophagus.
Why is this the key diagnostic feature of Esophageal Eosinophilia?
The presence of a high number of eosinophils in the esophageal tissue confirms the diagnosis of eosinophilic esophagitis, distinguishing it from other causes of esophagitis.
What are the differentials for Esophageal Eosinophilia, and why are they considered?
GERD: Often responds to acid suppression and shows different histological findings. Esophageal Stricture: Structural narrowing, may have different histological findings.

What are the differentials for Postpartum Hemorrhage, and why are they considered?
Atonic Uterus: Most common cause of postpartum hemorrhage, treated with uterine massage. Retained Placenta: Suspected if the placenta is not delivered within a reasonable time post-birth.
Why are these differentials considered for Postpartum Hemorrhage?
Uterine atony is the leading cause of postpartum hemorrhage, where the uterus fails to contract adequately after delivery. Retained placenta can also prevent proper uterine contraction, leading to continued bleeding. Both require prompt intervention to prevent severe blood loss.
What is the specific initial investigation for Postpartum Hemorrhage?
Physical examination to determine if the placenta has been delivered.
Why is this the initial investigation for Postpartum Hemorrhage?
Determining the status of the placenta is critical for deciding the next steps in management, whether it involves uterine massage, manual removal, or other interventions to control bleeding.
