One-liner
This episode covers high-yield newborn topics including Fanconi syndrome/Type 2 RTA, congenital syndromes like Turner and CHARGE, differentiating midline vs. lateral neck masses (Thyroglossal vs. Branchial), neonatal GI emergencies (midgut volvulus, meconium ileus), and common physical exam findings (Pectus excavatum, acrocyanosis).
High-yield summary
- Fanconi Syndrome: Presents with Type 2 RTA (hypokalemic NAGMA, urine pH <5.5) and often associated with radial ray deficiency (e.g., absent radius). Also look for Caffeoli spots.
- Congenital Neck Masses: Midline masses that move with swallowing suggest a Thyroglossal duct cyst (endodermal origin); lateral masses do not move with swallowing and suggest a Branchial cleft cyst (ectodermal origin).
- Neonatal GI Emergencies: Bilious vomiting + double bubble sign suggests duodenal atresia; bilious vomiting + triple bubble sign suggests gastric atresia. Midgut volvulus is associated with malrotation.
- Skeletal/Soft Tissue: Pectus excavatum causes restrictive lung disease due to chest wall restriction, while Poland syndrome involves unilateral absence of pectoralis muscles and ribs.
- Neonatal Skin Findings: Mongolian spots are benign dermal pigmentation in African-American infants; acrocyanosis is normal peripheral cyanosis due to immature vasomotor regulation.
Learning objectives
- Differentiate between various congenital neck masses based on their embryological origin and movement patterns.
- Recognize the classic triad associated with Fanconi syndrome (Type 2 RTA, skeletal anomalies, skin findings).
- Interpret neonatal abdominal imaging findings to differentiate duodenal atresia from gastric atresia or midgut volvulus.
- Apply knowledge of congenital musculoskeletal defects (e.g., Pectus excavatum, Poland syndrome) and their associated physiological consequences (restrictive lung disease).
- Differentiate between benign newborn skin/soft tissue findings (Mongolian spot, acrocyanosis, hemangioma) and concerning pathology.
