Ciguatera fish poisoning.Am Fam Physician. 1994 Sep 01; 50(3):579-84.AF
Ciguatera fish poisoning is the most common foodborne illness related to fin fish consumption and is endemic throughout the Caribbean and Indo-Pacific regions. The clinical picture is characterized by a variety of gastrointestinal, neurologic and, occasionally, cardiovascular symptoms. Patients with bradycardia and/or hypotension may require urgent care. Neurologic symptoms tend to be the most distinctive and enduring and include sensory changes such as generalized pruritus, circumoral numbness and reversal of hot and cold sensation. Intravenous mannitol has evolved as a unique remedy for patients with acute poisoning, but management of chronic symptoms continues to be problematic. Though difficult to implement, preventive strategies remain the best defense.
