Público ISBD Título : Introduction to the minisymposium: pediatric infectious diseases in Latin America Tipo de documento : documento electrónico Autores : Cadavid, Lina, Autor ; Ugas Charcape, Carlos F, Autor ; Fazecas, Tatiana, Autor Fecha de publicación : 2025 Títulos uniformes : Pediatric Radiology Idioma : Inglés (eng) Resumen : We are pleased to present the Minisymposium on Pediatric Infectious Diseases in Latin America, featuring six pictorial reviews of key imaging fndings in neglected tropical diseases and tuberculosis. This work highlights pressing regional health challenges, including congenital ZIKV infection, hydatid disease, ascariasis, leishmaniasis, chikungunya, dengue, and CNS and osteoarticular tuberculosis. Neglected tropical diseases disproportionately afect the world’s poorest populations, with over 700,000 deaths annually. Despite recent declines, Latin America reports high incidences, particularly in tropical areas. The COVID-19 pandemic disrupted progress, reducing community interventions and access to care. Meanwhile, tuberculosis, a persistent public health issue, has recently resurged in some countries in the region. Zika virus outbreaks have highlighted its congenital CNS efects, including microcephaly, calcifcations, cerebral atrophy, and corpus callosum anomalies. Ascariasis, prevalent in areas with poor hygiene, often causes gastrointestinal or pulmonary symptoms, with imaging fndings such as real-time movement of echogenic defects on ultrasound and ground-glass or alveolar infltrates on CT. Leishmaniasis often presents with nonspecifc fndings, Dengue can cause hepatosplenomegaly, pleural efusions, gallbladder wall edema, and ascites, with severe cases leading to hemorrhagic manifestations or CNS involvement. Chikungunya typically presents with arthralgia, arthritis, and synovitis. Hydatid disease, afecting multiple organs, relies on imaging for diagnosis, with ultrasound, CT, and MRI crucial for identifying cysts and complications. Tuberculosis in children manifests in the CNS as tuberculomas or meningitis. Osteoarticular tuberculosis accounts for 10–20% of extrapulmonary cases, with common presentations including spondylitis, arthritis, and osteomyelitis. We deeply appreciate Dr. Epelman for inspiring this project, the frst to feature exclusively Latin American authors. Her invaluable guidance made this initiative possible. Through this minisymposium, the Sociedad Latinoamericana de Radiología Pediátrica (SLARP) fulflls its mission to promote regional research and share insights on globally relevant yet underexplored topics, engaging readers worldwidesuch as hepatosplenomegaly and lymphadenopathy.

Pulmonary imaging in coronavirus disease 2019 (COVID-19): a series of 140 Latin American children / Lina Marcela Cadavid Álvarez

Objective: The purpose of the study was to analyze the imaging findings of pulmonary COVID-19 in a large pediatric series. Materials and methods: Children with SARS-CoV-2 infection confirmed by either quantitative reverse transcription-polymerase chain reaction from nasopharyngeal swabs or presence of circulating immunoglobulin M (IgM) antibodies and who underwent chest radiograph or CT or both were included in this retrospective multicenter study. Three pediatric radiologists independently reviewed radiographs and CTs to identify the presence, localization, distribution and extension of pulmonary lesions. Results: We included 140 children (71 female; median age 6.3 years, interquartile range 1.6–12.1 years) in the study. Peribronchial thickening (93%), ground-glass opacities (79%) and vascular engorgement (63%) were the most frequent findings on 131 radiographs. Ground-glass opacities (91%), vascular engorgement (84%) and peribronchial thickening (72%) were the most frequent findings on 32 CTs. Peribronchial thickening (100%), ground-glass opacities (83%) and pulmonary vascular engorgement (79%) were common radiograph findings in asymptomatic children (n=25). Ground-glass opacity and consolidation were significantly higher in children who needed intensive care admission or died (92% and 48%), in contrast with children with a favorable outcome (71% and 24%, respectively; P Mención de responsabilidad : Carlos F.
