RESUMO
BACKGROUND Ciguatera poisoning is presently estimated to afflict approximately 16 000 people in the United States each year. Ciguatera toxicity is due to the ingestion of warm-water reef fish that are known to consume dinoflagellates that contain ciguatoxins (CTXs). Historically, the diagnosis of ciguatera poisoning is confirmed in the emergency department when this ingestion is followed by manifestations of neurologic and gastrointestinal organ symptoms. Some individuals also manifest cardiac symptoms. These symptoms can vary within each organ system in type and duration. CASE REPORT In this report, 2 patients (husband and wife) are presented that consumed the same barracuda, resulting in severe ciguatera poisoning diagnosed in the emergency department. One had the complete triad of symptoms of gastrointestinal (GI), neurologic, and cardiac involvement. The other patient lacked neurological symptoms but did experience severe gastrointestinal and cardiac symptoms. It was assumed by the inpatient team, the consulted infectious disease specialist, and, initially, the in-house toxicologist that the lack of neurologic symptoms excluded the diagnosis of ciguatera. CONCLUSIONS If these patients had presented separately, only the former would have been considered to have ciguatera poisoning. These 2 cases demonstrate the misunderstanding among healthcare practitioners of the literature on the diagnostic criteria. Therefore, this article aims to analyze ciguatera diagnosis in the emergency department, which will ultimately guide prognostics and management, particularly for severe cardiac symptoms.

Chicago's lead problem has been shown to disproportionately affect populations of color and lower socioeconomic status (SES). The disproportionate effects on low-income areas and communities of color can be traced back to several key decisions in Chicago's history. A search of the National Library of Medicine's MEDLINE/PubMed as well as Google, and Google Scholar was performed to find all articles relating to lead poisoning in Chicago, lead utilization, Chicago's municipal and political history, and lead physiology between May 2020 and May 2023. Additionally, several studies and textbooks were reviewed regarding the latest advancements in lead poisoning. The study identified several key political moves over the course of Chicago's history that have resulted in disproportionate toxicity in minority populations and those of lower SES. Lead is more readily absorbed in the pediatric population. Additionally, prior regulations had published acceptable blood lead levels (BLLs) in children, but more recent evidence indicates a myriad of detrimental effects in BLLs below that cutoff. There is substantial evidence to suggest that there is no acceptable BLL. Lead toxicity is generally improving nationally but there still exists a considerable need for improvement. Programs should be expanded to ensure that individuals living in communities most at risk of lead exposure have the means to both, replace lead-contaminated infrastructure, and to be able to supply these communities with affordable housing. From a physician and clinician standpoint, knowing the increased risk of lead poisoning in these populations should prompt earlier testing.
