Nelson Pediatric Symptom-Based Diagnosis: Common Diseases and their Mimics
תאריך יציאה לאור
6 באפר׳ 2022
Patients don’t present with a disease; they present with symptoms. Using a practical, symptom-based organization, Nelson Pediatric Symptom-Based Diagnosis: Common Diseases and their Mimics, 2nd Edition, offers authoritative guidance on differential diagnosis and treatment of diseases and disorders in children and adolescents, and covers the symptoms you’re likely to see in practice, their mimics, and uncommon disorders. Drs. Robert M. Kliegman, Heather Toth, Brett J. Bordini, and Donald Basel walk you through what to consider and how to proceed when faced with common symptoms such as cough, fever, headache, autistic-like behaviors, chronic pain, chest pain, gait disturbances, and much more.
