Infant Botulism: Checklist for Timely Clinical Diagnosis and New Possible Risk Factors Originated from a Case Report and Literature Review.

ABSTRACT: Infant botulism is a rare and underdiagnosed disease caused by BoNT-producing clostridia that can temporarily colonize the intestinal lumen of infants less than one year of age. The diagnosis may be challenging because of its rareness, especially in patients showing atypical presentations or concomitant coinfections. In this paper, we report the first infant botulism case associated with Cytomegalovirus coinfection and transient hypogammaglobulinemia and discuss the meaning of these associations in terms of risk factors. Intending to help physicians perform the diagnosis, we also propose a practical clinical and diagnostic criteria checklist based on the revision of the literature.

Project description:AudienceEmergency medicine and pediatric residents, and pediatric emergency medicine (PEM) fellows.IntroductionBotulism is a rare but serious cause of infant hypotonia, vomiting, and respiratory failure. The differential diagnosis and management of a hypotonic infant with progressive weakness leading to respiratory failure is a rare presentation with high morbidity and mortality.1 Infants with botulism generally present with vague complaints that progressively worsen over time.2 Recognition of descending paralysis in an infant as well as signs of respiratory failure are key to preventing an adverse outcome. A key component of botulism treatment is recognizing the need to mobilize local resources to obtain BabyBIG® (botulism immune globulin). This process can and should begin in the emergency department.Educational objectivesAfter this simulation learners should be able to: 1) develop a differential diagnosis for the hypotonic infant, 2) recognize signs and symptoms of infant botulism, 3) recognize respiratory failure and secure the airway with appropriate rapid sequence intubation (RSI) medications, 4) initiate definitive treatment of infant botulism by mobilizing resources to obtain antitoxin, 5) continue supportive management and admit the patient to the pediatric intensive care unit (PICU), 6) understand the pathophysiology and epidemiology of infant botulism, 7) develop communication and leadership skills when evaluating and managing critically ill infants.Educational methodsThis simulation case was performed using a high-fidelity Laerdal SimBaby with intubating capabilities and real-time vital sign monitoring. Additionally, this case can be performed with low fidelity manikins with supplemental scripting and visual stimuli. With minor adjustments, this case could be modified into an oral boards case.Research methodsWe obtained feedback from a convenience sample of random participants after the simulation case and debrief were completed. The sample of emergency medicine residents (N=21) and PEM fellow (N=1) completed 5 questions on a 5-point Likert scale.ResultsThe emergency medicine residents and PEM fellow had mostly favorable feedback regarding the simulation and debriefing. Most strongly agreed or agreed that this would improve their performance in an actual clinical setting.DiscussionInfant botulism is a rare condition, presenting as vague non-specific complaints that worsen over time. It is important to differentiate infant botulism from other causes of weakness, hypotonia, and respiratory failure. This case presents learners with a high acuity, rare case of infant botulism and allows them to work through a complex pediatric patient encounter in a psychologically safe space. The presence of a standardized patient to play the patient's parent is key to assess learners' nontechnical communication skills and to increase fidelity during the simulation.TopicsInfant botulism, pediatric emergency medicine, respiratory failure, hypotonia, toxicology.
