Sore throat represents one of the main causes of antibiotic overprescription in children. Its management is still a matter of debate, with countries considering streptococcal pharyngotonsillitis a benign and self-limiting condition and others advocating for its antibiotic treatment to prevent suppurative complications and acute rheumatic fever. Italian paediatricians frequently prescribe antibiotics on a clinical basis regardless of microbiological results.

Article Synopsis
  • A survey was conducted among 32 senior clinicians across 20 European countries to understand current practices in postnatal prophylaxis (PNP) and infant feeding guidelines.
  • Twenty-three clinicians responded, revealing that all countries use risk stratification for PNP, but methods and regimens widely differ, with zidovudine being the most commonly used drug.
  • There is significant variation in guidelines regarding infant feeding for babies born to HIV-positive parents, highlighting the need for harmonization in policies to minimize HIV transmission and support informed feeding choices.

Background: COVID-19 is generally milder in children than in adults, however severe infection has been described in some patients. Few data are available on use of Remdesivir (RDV) in children, as most clinical trials focused on adult patients. We report a multicenter study conducted in 10 Italian Hospitals to investigate the safety of RDV in children affected by COVID-19.

Article Synopsis
  • * Three main management strategies emerged: one endorsing antibiotics to prevent acute rheumatic fever, another viewing pharyngitis as self-limiting, and a third adjusting treatment based on individual risk for rheumatic fever.
  • * The findings highlight inconsistencies across international guidelines, suggesting the need for a unified global approach and further research on cost-effectiveness and local GABHS epidemiology.

  • A study was conducted to evaluate the safety and immune response of a new RSV vaccine (ChAd155-RSV) in infants aged 6-7 months, comparing different doses and an active comparator.* -
  • The trial involved 201 infants, with results indicating that the vaccine had a safety profile comparable to existing childhood vaccines, and did not lead to adverse respiratory effects associated with RSV infections.* -
  • Higher doses of the ChAd155-RSV vaccine produced stronger immune responses, with increased antibody levels observed after vaccination, especially following the second dose.*

Background: US Food and Drug Administration has issued Emergency Use Authorizations for hundreds of serological assays to support Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) diagnosis. The aim of this study is to evaluate, for the first time in children, the performance of three widely utilized SARS-CoV-2 serology commercial assays, Diesse Diagnostics (IgG, IgA, IgM) and Roche Diagnostics, both Roche Nucleocapsid (N) IgG and Roche Spike (S) IgG assays.

Methods: Sensitivity and 95% confidence intervals (CIs) were estimated for each of the three different serological tests and mixed and direct comparison were performed.

Background: Two sequelae of pediatric COVID-19 have been identified, the multisystem inflammatory syndrome in children (MIS-C) and the long COVID. Long COVID is much less precisely defined and includes all the persistent or new clinical manifestations evidenced in subjects previously infected by SARS-CoV-2 beyond the period of the acute infection and that cannot be explained by an alternative diagnosis. In this Intersociety Consensus, present knowledge on pediatric long COVID as well as how to identify and manage children with long COVID are discussed.

Surgical site infections (SSIs), which are a potential complications in surgical procedures, are associated with prolonged hospital stays and increased postoperative mortality rates, and they also have a significant economic impact on health systems. Data in literature regarding risk factors for SSIs in pediatric age are scarce, with consequent difficulties in the management of SSI prophylaxis and with antibiotic prescribing attitudes in the various surgical procedures that often tend to follow individual opinions. The lack of pediatric studies is even more evident when we consider surgeries performed in subjects with underlying conditions that may pose an increased risk of complications.

Article Synopsis
  • The rapid spread of SARS-CoV-2 has necessitated quick advancements in treatment options, particularly the approval of monoclonal antibodies (mAbs) for patients aged 12 and older with specific risk factors.
  • Two specific combinations of mAbs, Bamlanivimab+Etesevimab and Casirivimab+Imdevimab, have shown effectiveness in treating adult patients in the early stages of COVID-19, but data on their use in children remains scarce.
  • A consensus document created by the Italian Society of Pediatrics aims to clarify which pediatric patients are at greater risk of severe COVID-19 based on existing literature, helping clinicians to better determine who should receive mAbs treatments.

Importance: Severe gastrointestinal (GI) manifestations have been sporadically reported in children with COVID-19; however, their frequency and clinical outcome are unknown.

Objective: To describe the clinical, radiological, and histopathologic characteristics of children with COVID-19 presenting with severe GI manifestations to identify factors associated with a severe outcome.

Design, Setting, And Participants: A multicenter retrospective cohort study (February 25, 2020, to January 20, 2021) enrolled inpatient and outpatient children (aged <18 years) with acute SARS-CoV-2 infection, confirmed by positive real-time reverse-transcriptase-polymerase chain reaction on nasopharyngeal swab or fulfilling the US Centers for Disease Control and Prevention criteria for multisystem inflammatory syndrome in children (MIS-C).

  • Recurrent respiratory infections (RRIs) are common in children, affecting about 25% of those under 1 year and 6% in the first 6 years, typically resolved by age 12.
  • While most cases are mild, RRIs can significantly impact quality of life for both children and their families, leading to higher medical and social costs.
  • This consensus document seeks to clarify the definition of RRIs and provide guidelines for physicians regarding their diagnosis, management, and prevention.

Background: Acute hematogenous osteomyelitis (AHOM) is an insidious infection of the bone that more frequently affects young males. The etiology, mainly bacterial, is often related to the patient's age, but it is frequently missed, owing to the low sensitivity of microbiological cultures. Thus, the evaluation of inflammatory biomarkers and imaging usually guide the diagnosis and follow-up of the infection.

Article Synopsis
  • This study investigates the characteristics of SARS-CoV-2 infections in children and adolescents, focusing on the factors that lead to more severe cases.
  • Conducted across multiple centers in Italy, it included 759 kids under 18, finding that most showed symptoms, with fever being the most prevalent.
  • Key findings indicate that complications and severe outcomes are linked to comorbidities and younger age groups, especially those with additional viral infections, underscoring the need for better management strategies.

Background: Although eHealth technology makes it possible to improve the management of complex health care systems and follow up on chronic patients, it is not without challenges, thus requiring the development of efficient programs and graphic user interface (GUI) features. Similar information technology tools are crucial, as health care populations are going to have to endure social distancing measures in the forthcoming months and years.

Objective: This study aims to provide adequate and personalized support to complex health care populations by developing a specific web-based mobile app.
