RESUMO
Two otherwise healthy middle-aged males presented with persistent abdominal and lower- back pain, progressive weakness, paraesthesias, fatigue and weight loss over 8-12 months. Extensive work-up failed to localize organ pathology. Both men, strongly aware of the nutritional benefits of fish had a diet dedicated of canned and fresh fish. Raised blood mercury levels confirmed clinical suspicion and serial levels declined with symptom resolution after excluding dietary fish. To gain reported health benefits of fish as a healthy food modest consumption is encouraged. Efforts to monitor fish consumption and mercury residues in fish are recommended in Trinidad and Tobago.

Intravenous mannitol was given to 16 patients with acute ciguatera fish poisoning requiring hospital admission. Thirteen patients (81 percent) presented with sensory and neuromuscular sympthoms; paraaesthesiae and pain and weaknwss in the lower limbs were predominant features. Mannitol had little effect upon gastrointestinal manifestations, but a marked reduction was observed in the expected duration of neurological symptoms. Although these results are empirical and uncontrolled, they suggest that mannitol infusion may be effective in altering the clinical course of acute ciguatera fish poisoning (AU)

This article highlights an outbreak of food poisoning, the result of ingestion of Ciguatoxin-infected fish in a community. The case presentations of the patients involved are used to illustrate the clinical aspects of Ciguatoxin poisoning. The public health aspects of this incident and their relevance to disease surveillance are then discussed. Information of significance to general medical practice in relation to this particular type of fish poisoning, the effect of which could prove fatal in some cases, is also discussed (AU)

Five people who ate fish at an evening meal became ill 6-8 hours later. Early symptoms included diarrhoea, vomiting, leg weakness and parasthesia. Emergency management for three patients took place in a Casualty Department and they were discharged within 8 hours. However, while the patients were recovering, a variety of other symptoms developed but they were able to return to school and work within 1-2 weeks, though symptoms persisted for some weeks thereafter. This small outbreak of ciguatera fish poisoning highlights the need for more information about this disease among the general public and the medical profession (AU)
