Severe morel mushroom poisonings in France - a nationwide French poison centres study 2010-2020.

INTRODUCTION: In 2023, two fatalities attributed to the ingestion of uncooked morels (Morchella spp.) were reported in the United States; both patients developed severe gastrointestinal symptoms. Morel-induced gastrointestinal toxicity is well recognized, but no deaths had been reported until 2023, suggesting a potential shift in the severity of morel poisoning. METHODS: Using the Poisoning Severity Score, we analyzed the severity of symptomatic cases of morel ingestion recorded in the French National Database of Poisonings from 2010 to 2020. RESULTS: We found 446 cases of exposure in which morels were the sole mushroom species involved. Of these, 83.6 per cent and 53.3 per cent developed gastrointestinal and neurological symptoms, respectively. Eight patients developed shock attributed to severe gastrointestinal symptoms, resulting in two deaths. DISCUSSION: Morel ingestion can lead to severe complications. As in the United States, the deaths reported in this study were attributed to imported cultivated morels. The shift, since 2006, towards a predominance of cultivated over wild morel sales may have played a role in the reporting of severe cases of morel poisoning. CONCLUSIONS: Reports of severe morel poisoning highlight the need for cautious consumption, particularly of raw or undercooked preparations. Emerging complications signal potential changes in toxicity. Surveillance and awareness are key to reducing the risks of consuming morels.

Short message service as a tool for mass follow-up of patients requesting a poison centre: a retrospective comparative study in France.

INTRODUCTION: The short message service is an alternative to telephone follow-up of exposure cases reported to poison centres. The aim of this study was to compare the proportion of exposure cases successfully followed up and the respective cost of telephone and short message service follow-up between two poison centres, one using both methods of follow-up (Paris centre) and the other using telephone follow-up only (Nancy centre). METHODS: In 2021, we included cases eligible for short message service follow-up at both centres. Eligibility criteria were calls from the public reporting non-toxic or minor toxic exposure not requiring medical consultation. We collected the follow-up type (telephone/short message service) and outcome (success/failure). The cost of each type of follow-up was estimated. RESULTS: In 2021, 16,867 and 11,107 exposure cases were eligible for short message service follow-up at the Paris and Nancy centres, respectively. The Paris centre followed up 86.2 per cent of cases by short message service, and the remainder by telephone, while the Nancy centre followed up all cases by telephone. The Paris centre had a greater follow-up rate compared to the Nancy centre (93.0 per cent versus 43.6 per cent; P < 0.0001). Overall, the success rates were similar between the two centres (P = 0.06), with short message service and telephone follow-up showing comparable success rates (88.1 per cent versus 88.7 per cent; P = 0.25). On average, telephone follow-up took almost twice as long (1.51 min versus 0.85 min) and cost 1.3 times more (0.59 euros versus 0.45 euros) than short message service follow-up. DISCUSSION: Short message service follow-up allows more patients to be successfully followed up at a lower cost compared to telephone-only follow-up, albeit with potential differences in information quality. CONCLUSIONS: Short message service follow-up is a promising tool for poison centres to follow up with patients. Further studies are needed to assess the quality of the data collected and caller satisfaction.
