Nasal provocation tests in the diagnosis of urticaria induced by acetylsalicylic acid

Ciguatera fish poisoning is the most common form of toxin-related food poisoning in the United States. Originating from dinoflagellates living on coral reefs, it is spread up the food and affects humans who ingest the ciguatoxic fish. Ciguatera is primarily endemic in tropical regions of the world. It is a self-limiting disease that presents with characteristic gastrointestinal, neurological, and cardiovascular symptoms. Recent advances in testing procedures and symptom recognition has improved ciguatoxin identification and clinical management. However, there is still a need for better diagnostic, preventive, and reporting protocols to more accurately study and understand this diverse and temporarily debilitating clinical syndrome.
