One-liner
This comprehensive review emphasizes high-yield pediatric topics including immunodeficiency syndromes (Bruton's, SCID, CGD), abdominal masses (Wilms vs Neuroblastoma), vasculitides (Kawasaki, HSP), and common musculoskeletal/neurological presentations like sleep disorders and congenital torticollis.
High-yield summary
- Sleep Disorders: Sleep Terror Disorder occurs during N3 sleep with zero recollection of the event; contrast this with Nightmare Disorder, which involves vivid recollections during REM sleep. Reassurance is often the initial management step for parasomnias.
- Immunodeficiency Syndromes: Remember the "bug pattern": Encapsulated bacteria suggest a B cell problem (e.g., Bruton's agammaglobulinemia); T cell deficiencies are associated with severe infections and developmental issues (e.g., SCID, DiGeorge Syndrome).
- Abdominal Masses: Wilms Tumor is derived from renal parenchyma and classically presents with the triad of hypertension, hematuria, and a flank mass. Neuroblastoma is derived from neural crest cells, often produces catecholamines, and masses are typically calcified or cross the midline.
- Vasculitis: Kawasaki Disease requires IVIG and high-dose ASA; monitor for coronary artery aneurysms via echo. Henoch-Schönlein Purpura (HSP) presents with palpable purpura on buttocks/lower extremities, abdominal pain, joint pain, and hematuria (IgA nephropathy).
- Lyme Disease: The preferred treatment is Doxycycline, but for children < 8 years old, Amoxicillin is used to prevent permanent tooth discoloration.
Learning objectives
- Differentiate between various pediatric abdominal masses (Wilms vs Neuroblastoma).
- Identify the appropriate antibiotic and treatment for common childhood infections (e.g., Lyme, osteomyelitis).
- Recognize the clinical presentation and initial management of major vasculitides (Kawasaki, HSP).
- Master the differential diagnosis of congenital musculoskeletal findings (Torticollis, Nursemaid Elbow).
- Correlate genetic/syndromic features with specific developmental or physical anomalies.
