Neonatal severe COVID-19 infection complicated by Staphilococcus aureus could be misinterpreted as MIS-C?: case report and review of literature.

At 23 days of life a neonate presented to the emergency room with crying and decreased oral intake. His parents were positive to SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), but he turned out negative. After one week he was admitted to NICU (neonatal intensive care unit) for respiratory failure, and nasopharyngeal swab (PCR test: polymerase chain reaction test) was positive for SARS-CoV-2. On examination the child had fever, tachy-dyspnea, reduced oxygen saturation, tachycardia, abdominal distension and tenderness, irritability and hypertonia. Blood exam showed respiratory acidosis, lymphocytopenia, hypoalbuminemia and coagulopathy; CRP (C reactive protein), procalcitonin, D-dimer, ferritin and NT-proBNP (N-terminal prohormone of brain natriuretic peptide) were elevated. Chest X-ray revealed bilateral interstitial infi ltration and abdomen ultrasound a thin fl uid effusion; echocardiography was normal. SARS-CoV-2 PCR tests on CSF (cerebrospinal fluid) and stool were also positive. He was started on non-invasive intermittent positive pressure respiratory ventilation, treated with antibiotic therapy, methylprednisolone, intravenous immunoglobulins, and antiplatelet therapy. Rapid clinical improvement was seen with remission of fever after eight days. The child complicated with bacterial super-infection presenting as pleural empyema. As presented in our case, it is not always easy to differentiate between severe forms of COVID-19 and MIS-C. Due to the rarity of these presentations in neonates, multicentric collaboration is needed to identify the specifi c characteristics of the two forms, better defi ne diagnostic criteria, and treatment options.

Disease Characteristics and Psychiatric Comorbidities in Adolescents with Anorexia Nervosa Hospitalized During COVID-19 Pandemic.

BACKGROUND: Since the beginning of COVID-19 pandemic, an increase in new diagnoses and pediatric hospital admission for anorexia nervosa (AN) or atypical AN in adolescents have been reported, suggesting an adverse effect of COVID-19 on youth mental health. We hypothesized possible differences in prevalence of hospitalization and/or disease severity, related to socio-economic status and/or ethnicity. METHODS: Retrospectively, patients were divided into two subgroups and compared according to the date of first hospital admission: "pre SARS-COV2 era" group (n. 45, 8th March 2016-8th March 2020) and "SARS-COV2 era" group (n. 43, 9th March 2020-8th March 2022). RESULTS: During the two years of the SARS-COV2 era, we reported an increase in hospital admission incidence more than doubled respect to the "pre-SARS-COV2 era". The "SARS-COV2 era group" showed a more rapid weight loss (p = 0.005), a minor duration of weight loss from lifetime maximum to admission (p = 0.019) and needed most frequently treatments with intravenous fluids (p < 0.0001), oral dietetic supplements (p <0.001) and enteral nutrition by nasogastric tube (p = 0.002). The same group presented higher prevalence of psychiatric comorbidities (63% vs. 22%, p < 0.0001) and required most frequently treatments with psychotropic drugs (56% vs. 24%, p = 0.002). We found higher family socioeconomic status (SES) in our patients with AN in both the periods and we did not find a shift in social class distribution over time. CONCLUSIONS: Our study confirms a significant increase in incidence of hospitalization and of psychiatric comorbidity in the pediatric population with AN during the second year of COVID-19 pandemic, regardless of SES or ethnic background. Further studies are needed to understand potential mechanisms that during COVID-19 pandemic trigger eating disorder symptoms.
