Episode Title:
🔑 Pediatric Rickets Simplified — Types, Features, Mnemonics & PYQs
Episode Description (for Spotify):
Rickets keeps coming back in NEET-PG & INI-CET — both in short stems and clinical vignettes. In this episode, we break it down into bite-sized, exam-friendly pearls with easy mnemonics:
📌 What You’ll Learn:
1. Definition & Basics
• Rickets = defective mineralization of growth plate (children).
• Osteomalacia = defective mineralization of osteoid (adults).
2. Types of Rickets
• Nutritional (Vit D deficiency) → most common.
• Vitamin D–dependent (Type I & II)
• Vitamin D–resistant (Hereditary hypophosphatemic rickets)
• Renal rickets (CKD, renal tubular acidosis).
3. Clinical Features (Mnemonic: RICKETS)
• Rosary (rachitic rosary at costochondral junction)
• Inward bowing of legs (genu varum/valgum)
• Craniotabes + delayed closure of fontanelle
• Kyphoscoliosis & knock knees
• Epiphyseal widening + cupping/fraying of metaphysis
• Tetany (hypocalcemia)
• Stomach protrusion (potbelly, Harrison’s sulcus)
4. Radiology Mnemonic: WFR
• Widened growth plates
• Fraying of metaphysis
• Rachitic rosary
5. Important Lab Patterns
• Nutritional Rickets: ↓Ca, ↓PO₄, ↑ALP, ↑PTH
• Vit D–dependent I: ↓1α-hydroxylase → low calcitriol
• Vit D–dependent II: End-organ resistance → high calcitriol
• Hypophosphatemic: Low phosphate, normal calcium
6. Memory Pegs for Types:
• Type I: Hydroxylase defect — think “I can’t Hydroxylate.”
• Type II: Receptor defect — think “II = Resistant.”
7. PYQ Connections
• NEET-PG 2021: child with frontal bossing + rachitic rosary → diagnosis?
• INI-CET 2022: lab values with low phosphate, normal calcium → hypophosphatemic rickets.
• NEET-PG 2018: child with multiple fractures, vit D supplementation not working → Vit D-dependent Type II.
🧠Key Takeaway:
“One table (Ca, PO₄, ALP, PTH) + one mnemonic (RICKETS) = 3–4 sure-shot questions.”
