Background: SARS-CoV-2 variations as well as immune protection after previous infections and/or vaccination may have altered the incidence of multisystemic inflammatory syndrome in children (MIS-C). We aimed to report an international time-series analysis of the incidence of MIS-C to determine if there was a shift in the regions or countries included into the study. Methods: This is a multicenter, international, cross-sectional study. We collected the MIS-C incidence from the participant regions and countries for the period July 2020 to November 2021. We assessed the ratio between MIS-C cases and COVID-19 pediatric cases in children <18 years diagnosed 4 weeks earlier (average time for the temporal association observed in this disease) for the study period. We performed a binomial regression analysis for 8 participating sites [Bogotá (Colombia),
Introduction: Clostridium botulinum is known to cause descending paralysis in infants throughout the world. Methodology: The subject of this study was a three-month-old Costa Rican boy who was hospitalized because of poor suction and feeding, hypotonia, and constipation. Clinical history and physical examination findings suggested infant botulism. Samples were sent to the Winnipeg Public Health Laboratory, where Clostridium botulinum toxin A was identified by PCR and culture from the stools, making this the first report of infant botulism in Central America. Conclusions: Although infant botulism is a known disease, the limitations in identifying it in Central America contributes to the misdiagnosis and under-reporting of this disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
