Summary: Introduction. Acute urticaria (AU) in children is a common clinical manifestation responsible for admission to the emergency department (ED). We aimed to analyze the epidemiological characteristics of AU in children and to identify predictors of both severity and progression. Material and methods. We evaluated 314 children admitted to the ED with a diagnosis of AU. We analyzed information concerning its onset, duration, severity, possible triggering factors, and the persistence of symptoms after 1, 3, and 6 months. Results.

Background: To systematically review clinical and biochemical characteristics associated with the severity of the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-related disease (COVID-19). Materials and methods: Systematic review of observational studies from PubMed, ISI Web of Science, SCOPUS and Cochrane databases including people affected by COVID-19 and reporting data according to the severity of the disease. Data were combined with odds ratio (OR) and metanalysed.

SARS-CoV-2 infection shows a wide-ranging clinical severity, requiring prognostic markers. We focused on S100B, a calcium-binding protein present in biological fluids, being a reliable biomarker in disorders having inflammatory processes as common basis and RAGE as main receptor. Since Covid-19 is characterized by a potent inflammatory response also involving RAGE, we tested if S100B serum levels were related to disease severity. Serum samples (n = 74) were collected from hospitalized SARS-CoV-2 positive patients admitted to Covid center.

Context: Although health-related quality of life (HRQoL) is a fundamental outcome in oncological clinical trials, its evaluation in the neuroendocrine neoplasm (NEN) research field is still limited.
Objectives: This study assessed the role of clinical severity (i.e., presence or absence of metastasis and lines of therapies) and heterogeneity (i.e., primary site, types of therapy, biology and surgery) of NEN in relation to HRQoL, as well as resilience as a moderator between clinical severity and HRQoL.
Design: Cross-sectional multicentric study.

Background: Whether viral coinfections cause more severe disease than Bordetella pertussis (B. pertussis) alone remains
unclear. We compared clinical disease severity and sought clinical and demographic differences between infants with
B. pertussis infection alone and those with respiratory viral coinfections. We also analyzed how respiratory infections
were distributed during the 2 years study.
Methods: We enrolled 53 infants with pertussis younger than 180 days (median age 58 days, range 17–109 days, 64.

We aimed to study respiratory syncytial virus (RSV) genotype distribution, clinical presentation, and disease severity in infants with bronchiolitis from RSV subtypes and new RSV genotypes. Methods: We prospectively enrolled previously healthy term infants less than one year old hospitalized for bronchiolitis in an Italian University hospital over 12 epidemic seasons. In 312 nasopharyngeal washings positive to RSV, we sequenced the viral genotype and analysed it according to patient data. Strain-specific RSV loads were quantified for 300 specimens.
