The Toxicology Conundrums are targeted case-based question-&-answer toxicology quiz posts designed to highlight important principles, pitfalls, and ‘tricks of the trade’ for the clinical assessment and management of poisoned and envenomed patients.
The approach used is based on the “The Toxicology Handbook” (by Lindsay MurrayFrank DalyMark Little, and Mike Cadogan) – with links to other references where appropriate. Remember if you require urgent assistance with poisoning or envenoming – contact the Australia Poisons Information Service [PIC].
