Ciguatera Fish Poisoning (CFP) is the most frequently reported seafood-toxin illness in the world. It causes substantial human health, social, and economic impacts. The illness produces a complex array of gastrointestinal, neurological and neuropsychological, and cardiovascular symptoms, which may last days, weeks, or months. This paper is a general review of CFP including the human health effects of exposure to ciguatoxins (CTXs), diagnosis, human pathophysiology of CFP, treatment, detection of CTXs in fish, epidemiology of the illness, global dimensions, prevention, future directions, and recommendations for clinicians and patients. It updates and expands upon the previous review of CFP published by Friedman et al. (2008) and addresses new insights and relevant emerging global themes such as climate and environmental change, international market issues, and socioeconomic impacts of CFP. It also provides a proposed universal case definition for CFP designed to account for the variability in symptom presentation across different geographic regions. Information that is important but unchanged since the previous review has been reiterated. This article is intended for a broad audience, including resource and fishery managers, commercial and recreational fishers, public health officials, medical professionals, and other interested parties.

Ciguatera Fish Poisoning (CFP) is the most frequently reported seafood-toxin illness in the world, and it causes substantial physical and functional impact. It produces a myriad of gastrointestinal, neurologic and/or cardiovascular symptoms which last days to Mar. Drugs 2008, 6457 weeks, or even months. Although there are reports of symptom amelioration with some interventions (e.g. IV mannitol), the appropriate treatment for CFP remains unclear to many physicians. We review the literature on the treatments for CFP, including randomized controlled studies and anecdotal reports. The article is intended to clarify treatment options, and provide information about management and prevention of CFP, for emergency room physicians, poison control information providers, other health care providers, and patients.

This study examined the course of clinically significant cognitive change in hematopoietic stem cell transplant (HSCT), using a Reliable Change Index (RCI). Neuropsychological evaluations were administered to 117 patients before HSCT. Thirty-three received subsequent evaluations 6 and 28 weeks later. Of 117 patients, 39% were classified as impaired before HSCT. Of the 33 receiving subsequent evaluations, 47% showed reliable decline at 6-weeks; of these, 33% showed reliable decline again at 28-weeks. Mood and QOL did not account for declines. Verbal learning, psychomotor speed, and executive function showed greatest vulnerability to pre-HSCT impairment, and verbal learning showed greatest likelihood of further, subsequent decline. In conclusion, a subgroup of patients showed cognitive impairment before HSCT, indicating that factors other than HSCT contributed to cognitive deficits. Another subgroup showed further decline after HSCT. This study demonstrated the utility of the RCI in describing cognitive change in HSCT patients.
