[Pulmonary actinomycosis caused by Actinomycesodontolyticus in a two-year-old child].

Introduction: Pulmonary actinomycosis due to Actinomyces Odontolyticus is a rare and seldom reported pathology in pediatrics. The unspecific radio-clinical symptomatology and the slow growth of the germ make the diagnosis difficult.

Case Report: A 2-year-old boy is admitted to the emergency room for acute respiratory distress in a context of febrile bronchitis that had been evolving for 10days.

[Pediatric neuroborreliosis : diagnosis and treatment].

Neuroborreliosis is the second most frequent presentation of Lyme disease in children. Isolated facial palsy is the most classical manifestation of neuroborreliosis, but another clinical picture can be found in children: subacute meningitis, radiculoneuritis, or rarely severe neurological manifestations (transverse myelitis, encephalitis). Diagnosis and treatment guidelines of neuroborreliosis in children will be reviewed here.

COVID-19 in children and adolescents in Europe: a multinational, multicentre cohort study.

Background: To date, few data on paediatric COVID-19 have been published, and most reports originate from China. This study aimed to capture key data on children and adolescents with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection across Europe to inform physicians and health-care service planning during the ongoing pandemic.

Methods: This multicentre cohort study involved 82 participating health-care institutions across 25 European countries, using a well established research network-the Paediatric Tuberculosis Network European Trials Group (ptbnet)-that mainly comprises paediatric infectious diseases specialists and paediatric pulmonologists.
