This compendium includes over 50 high-yield topics authored by a distinguished panel of national experts, ensuring both depth and breadth. The inclusion of pediatric toxicology as a dedicated section acknowledges the growing burden of toxic exposures and poisoning, especially in under-resourced regions, and aims to provide life-saving clarity in such scenarios. Special care has been taken to ensure clarity of definitions, logical structuring of clinical algorithms, and consistency in therapeutic approaches. These features, combined with flowcharts and concise guidance, make the book not just a reference, but a reliable companion in the emergency room.
