SARS-CoV-2 is transmitted mainly via respiratory droplets. A key question in COVID-19 pandemic is whether it could be transmitted via airborne route as well. We report for the first time SARS-CoV-2 nosocomial infections, despite using surgical masks and physical distancing. It may provide a possible evidence for airborne transmission of SARS-CoV-2.

Social distancing and quarantines have major negative psychological implications. Our aim was to study the rate of pediatric hospitalizations due to anorexia nervosa (AN) during the first year of coronavirus disease 2019 (COVID-19) pandemic as compared to previous years, with regard to clinical and laboratory parameters. This is a retrospective study in a tertiary pediatric hospital in Israel. Data regarding inpatient hospitalizations due to AN were retrieved, then epidemiological, clinical, and laboratory parameters compared. During the entire study period, 275 hospitalizations were due to AN: 94 patients were admitted during the 12 months of the pandemic as compared to a yearly mean of 45.25 during 2015–2019, resulting in a 2.4-fold increase ( p < 0.001). The mean admission age and female predominance were similar in the two study groups. The weight of the patients at admission was higher during the COVID-19 period (44.5 kg vs. 41.2 kg, p = 0.004), and fewer patients had clinical signs typical of AN upon physical examination ( p = 0.022). There was a 35% reduction in median hospitalization duration (9 days [IQR 8.21] in 2020–2021 and 14 [IQR 6, 16.75] days in 2015–2019, p = 0.01). No other differences were found. Conclusions : During the first year of the COVID-19 pandemic, there was a significant increase in the number of adolescents hospitalized with AN. Nevertheless, disease characteristics were not more severe as compared to the preceding 5 years. What is Known: • Social distancing and quarantines were announced during the COVID-19 pandemic in numerous countries. These measures have potential negative psychological effects on adolescents. What is New: • During the COVID-19 pandemic period, there was an increase in the number of hospitalizations of adolescents with AN, although disease characteristics were not more severe as compared to the preceding 5 years.

Acute cerebellitis is a rare inflammatory condition. It may have a benign, self-limiting course or present as a fulminant disease resulting in severe cerebellar damage or even sudden death. We present the clinical, laboratory, and radiologic data in 9 children diagnosed with acute cerebellitis, who were identified by database search in our pediatric medical center from January 2000 to November 2014. The main presenting symptom was headache, and the main presenting sign was ataxia. Bilateral diffuse hemispheric involvement was the most common imaging finding at presentation. Mycoplasma pneumoniae was the most common infectious pathogen found. Treatment included steroids in all cases, antibiotics in 4, and intravenous immunoglobulins in 6. Six patients had a full recovery, and 3 had residual neurologic complications. Magnetic resonance imaging (MRI) is the modality of choice for diagnosis. The course of acute cerebellitis varies from a commonly benign and self-limiting disease to an occasionally fulminant disease, resulting in severe cerebellar damage or sudden death.
