RESUMO
BACKGROUND: It has been speculated that the SARS-CoV-2 was already widespread in western countries before February 2020. METHODS: We gauged this hypothesis by analysing the nasal swab of infants with either bronchiolitis or a non-infectious disease admitted to the Ospedale Maggiore, Milan (one of the first epicentres of SARS-CoV-2 outbreak in Europe) from November 2019. RESULTS: The SARS-CoV-2 RNA was never detected in 218 infants with bronchiolitis (95 females, median age 4.9 months) and 49 infants (22 females, median age 5.6 months) with a non-infectious disease between November 2019 and February 2020. On the contrary, two infants hospitalised for bronchiolitis between March and April 2020 tested positive for SARS-CoV-2. CONCLUSIONS: This study does not support the hypothesis that SARS-CoV-2 was already circulating among infants before the official outbreak of SARS-CoV-2 infection. However, it shows for the first time that SARS-CoV-2 might cause bronchiolitis requiring hospitalisation.

Rhomboencephalitis is a potentially life-threatening condition due to inflammation of the hindbrain with an unpredictable outcome depending on the wide spectrum of etiologies and the promptness of diagnosis and treatment. A 23-month-old Caucasian male presented with fever, clouding of consciousness, and trunk ataxia. Three weeks earlier he received active immunization against varicella-zoster virus. Routine laboratory tests were unremarkable. Cerebrospinal fluid showed might elevation of leukocytes. The infection panel was negative. Brain magnetic resonance showed signal hyperintensity in the dorsal portion of the pons, which was consistent with a rhomboencephalitis. Autoimmune pathogenesis was supposed and a high dose of steroids was started. The patient's neurologic status progressively improved till full recovery and complete regression of previous magnetic resonance lesions after 1 year. Nevertheless, longer follow-up is needed in order not to miss any possible signs of an underlying autoimmune neurologic disorder.
