**Question:** "Panda facies" is commonly seen after

A. neonatal sepsis
B. meningitis
C. Kawasaki disease
D. viral infections

**Core Concept:**

Panda facies is a term used to describe the characteristic facial features seen in children with Kawasaki disease, a systemic vasculitis affecting small and medium-sized arteries. The disease primarily affects children under 5 years of age and can lead to coronary artery aneurysms if not promptly treated. The term "Panda" comes from the characteristic bilateral swelling of the eyelids (edema) and the darker skin discoloration around the eyes (infraorbital edema), resembling a panda's face.

**Why the Correct Answer is Right:**

Kawasaki disease is the correct answer because it is the condition that leads to panda facies due to its characteristic vasculitis involving the blood vessels around the eyes, resulting in the described facial features. Kawasaki disease can cause coronary artery aneurysms if not treated promptly, which highlights the importance of recognizing and diagnosing this condition.

**Why Each Wrong Option is Incorrect:**

A. Neonatal sepsis: Sepsis can cause inflammation and tissue edema, but it does not lead to the specific facial features of panda facies.
B. Meningitis: Meningitis primarily affects the meninges and central nervous system, not the facial vessels, making it an incorrect choice for panda facies.
D. Viral infections: Various viral infections can cause inflammation and edema, but none of them result in the specific facial features of panda facies. Panda facies is unique to Kawasaki disease.

**Clinical Pearl:**

The term "Panda facies" serves as a useful mnemonic to remember the characteristic facial features of Kawasaki disease, which can aid in prompt diagnosis and treatment of this potentially life-threatening condition. Early recognition and treatment with intravenous immunoglobulin (IVIG) and aspirin can prevent coronary artery complications and improve outcomes for the child.
