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.

Background: The health and safety hazards related to button batteries (BB) have been extensively studied, highlighting that the presence of a button battery in the esophagus is a life-threatening emergency. However, complications related to bowel BB are poorly evaluated and not well known. The objective of this review of the literature was to describe severe cases of BB that have passed the pylorus., Case Report: This case, from the PilBouTox cohort, is the first report of small-bowel occlusion following ingestion of an LR44 BB (diameter: 11.4 mm) by a 7-month-old infant with a history of intestinal resections. In this case, the BB was ingested without a witness. The initial presentation mimicked acute gastroenteritis evolving into hypovolemic shock. An X-ray revealed a foreign body stuck in the small bowel causing an intestinal occlusion and local necrosis without perforation. The patient's history of intestinal stenosis and intestinal surgery were the contributing factor of impaction., Systematic Literature Review: The review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. The research was conducted on September 12, 2022 through five database and the U.S. Poison Control Center website. An additional 12 severe cases of intestinal or colonic injury after ingestion of a single BB were identified. Of these, 11 were related to small BBs (< 15 mm) that impacted Meckel's diverticulum and one was related to postoperative stenosis., Conclusion: In view of the findings, the indications for digestive endoscopy for extraction of a BB in the stomach should include a history of intestinal stenosis or intestinal surgery so as to avoid delayed intestinal perforation or occlusion and prolonged hospitalization., Competing Interests: Declaration of Competing Interest The authors have no competing financial interest or personal relationship that may be considered a potential competing interest., (Copyright © 2023.

Consumption of mushrooms can become unsafe for the consumer in case of confusion. Some fungi of Cortinarius genus contain the nephrotoxic mycotoxin orellanine responsible for their toxicity. Related case poisoning diagnosis is a challenge for both clinicians and analysts because of a long latency period between intake and toxic syndrome, the lack of available information in literature and the numerous pitfalls of orellanine identification/quantification in biological samples. In this situation, we propose an analytical method designed for the orellanine detection and/or quantification in biological matrices such as plasma, urine and whole blood, in a context of related intoxication suspected case. Using 1 mL biological sample volume, this liquid chromatographic with high-resolution mass spectrometry detection method (i) exhibits a limit of quantification for orellanine of 0.5 µg/L in plasma and urine and (ii) enables orellanine detection in whole blood with a limit of detection of 0.5 µg/L. This validated analytical method was successfully applied to 10 suspected intoxication cases., (© The Author(s) 2022. Published by Oxford University Press. All rights reserved.

In this study, we aimed to identify the factors related to esophageal impaction following button battery (BB) ingestion in children. PilBouTox, a prospective multicentric observational cohort study, was conducted from French Poison Control Centers between June 1, 2016 and May 31, 2018. Children (0-12 years old) with BB ingestion were included. After ingestion, patients were monitored for 21 days or more if they remained symptomatic (maximum 1 year). Causes of ingestion, clinical manifestations, medical management, and the outcomes were recorded. In total, 415 patients were included; among them, 35 had esophageal impaction and 14 had severe complications or died. Seven symptoms were closely related (relative risk (RR) > 30) to esophageal impaction: anorexia, drooling, dyspnea, fever, hemodynamic instability, pallor, and pain. Furthermore, BBs > 15 mm were related to esophageal impaction (RR = 19, CI 95% [4.1; 88]). The absence of initial symptoms was a protective factor for esophageal impaction (RR = 0.013, CI 95% [0.002; 0.1]). Nine symptoms were closely related (RR > 30) to major effects and death: dyspnea, cough, dysphagia, drooling, fever, hemodynamic instability, pain, pallor, and vomiting. Seven symptoms were related to esophageal impaction and their rapid recognition could help to ensure that the patient is taken to a health care facility. Nine factors were related to the major effects of BB ingestion. We recommended an X-ray as soon as possible to determine the position of the BB.Trial Registry: Clinical Trial ID: NCT03708250, https://clinicaltrials.gov/ct2/show/NCT03708250., (© 2022.

Introduction: In recent years, the number of patients managed by poison control centres (PCCs) has increased without a proportional increase in the number of physicians. To improve efficiency without neglecting patient follow-up, some PCCs have begun using text messages. We evaluated the difference in response rates between text messaging and traditional telephone follow-up., Materials and Methods: This retrospective, monocentric, non-randomised cohort study was conducted using data from calls made by the New Aquitaine PCC between February 27, 2019, and March 31, 2019. Patients were contacted up to three times by a phone call or short message service (SMS)., Results: For the analysis, 823 patients were included. At the end of follow-up, the response rates were similar in the phone call and SMS group (94 vs. 94%; p  = 0.76) with median [interquartile range] response times of 0 min [0; 27 min] and 29 min [6; 120 min], respectively. The response rates did not differ in subgroups stratified according to sex, self-poisoning vs. relative response, age class, and solicitation during working hours vs. outside of working hours (all p  > 0.5). Moreover, health practitioners required 2.4-fold more time to call than to send text messages ( p  < 0.001), and all practitioners were satisfied or very satisfied with text messaging implementation., Conclusion: Patients had good adherence to text messages. Text messages are easy to use, rapid, and allow the physician to easily prioritise follow-up without occupying the emergency line. Additionally, the costs of installation and maintenance are low for text message systems; these low costs facilitate the implementation of such services in various medical situations.
