Disrupted Seasonality of Respiratory Viruses: Retrospective Analysis of Pediatric Hospitalizations in Italy from 2019 to 2023.

This multicenter study in Italian hospitals highlights the epidemiologic disruptions in the circulation of the 5 main respiratory viruses from 2019 to 2023. Our data reveal a resurgence of respiratory syncytial virus and influenza during the 2022-2023 winter season, with an earlier peak in cases for both viruses, emphasizing the importance of timely monitoring.

Difficult Intravascular Access in Pediatric Emergency Department: The Ultrasound-Assisted Strategy (DIAPEDUS Study).

Vein line positioning represents one of the first diagnostic and therapeutic steps in Pediatric Emergency Department (PED); however, the outcome of this maneuver is frequently not as expected, especially for difficult-to-access (DIVA) patients. The standard technique (visual-palpatory) has a low success rate; hence ultrasound (US) assistance has been suggested for DIVA patients, although controversial results have been obtained. Our study compared the success rate of an intravascular (IV) access procedure at the first attempt, with and without ultrasound assistance, in pediatric DIVA patients. Secondary objectives were the global success rate, the mean procedural time, the IV device's life span, and the complications rate. We conducted an observational, prospective, monocentric, no-profit cohort study enrolling 110 patients presenting to our ED, aged 0-21 years. All the patients were considered difficult-to-access patients according to the DIVA score (≥4) or history of previous difficult intravascular access. They were randomized into two homogeneous groups: 50 patients with the standard and 60 with the US-assisted technique. We obtained a significantly higher success rate at first attempt with the US-guided technique (90% vs 18%, p ≤ .00001). Moreover, the overall success rate was higher in the US group (95% vs 46%, p < .00001). The mean procedural time resulted significantly less in the US group (2.7 ± 2.2 min vs 10 ± 6.4 min, p < .0001), as well as the overall number of attempts to obtain a stable IV line (1.09 ± 0.34 attempts vs 2.38 ± 1.09 attempts, p < .0001). We experienced some post-procedural complications without differences in the two groups, although none were severe. Our study showed that bedside ultrasound assisting implantation of peripheral venous access in pediatric DIVA patients improves first-time success rate, overall success rate, procedural time, and patient comfort, reducing the number of attempts to obtain a stable IV line.

Clinical course and peculiarities of Parechovirus and Enterovirus central nervous system infections in newborns: a single-center experience.

Parechovirus (HpEV) and Enterovirus (EV) infections in children mostly have a mild course but are particularly fearsome in newborns in whom they may cause aseptic meningitis, encephalitis, and myocarditis. Our study aimed to describe the clinical presentations and peculiarities of CNS infection by HpEV and EV in neonates. This is a single-center retrospective study at Istituto Gaslini, Genoa, Italy. Infants aged ≤ 30 days with a CSF RTq-PCR positive for EV or HpEV from January 1, 2022, to December 1, 2023, were enrolled. Each patient's record included demographic data, blood and CSF tests, brain MRI, therapies, length of stay, ICU admission, complications, and mortality. The two groups were compared to identify any differences and similarities. Twenty-five patients (15 EV and 10 HpEV) with a median age of 15 days were included. EV patients had a more frequent history of prematurity/neonatal respiratory distress syndrome (p = 0.021), more respiratory symptoms on admission (p = 0.012), and higher C-reactive protein (CRP) levels (p = 0.027), whereas ferritin values were significantly increased in HpEV patients (p = 0.001). Eight patients had a pathological brain MRI, equally distributed between the two groups. Three EV patients developed myocarditis and one HpEV necrotizing enterocolitis with HLH-like. No deaths occurred.  Conclusion: EV and HpEV CNS infections are not easily distinguishable by clinical features. In both cases, brain MRI abnormalities are not uncommon, and a severe course of the disease is possible. Hyper-ferritinemia may represent an additional diagnostic clue for HpEV infection, and its monitoring is recommended to intercept HLH early and initiate immunomodulatory treatment. Larger studies are needed to confirm our findings. What is Known: • Parechovirus and Enteroviruses are the most common viral pathogens responsible for sepsis and meningoencephalitis in neonates and young infants. • The clinical course and distinguishing features of Parechovirus and Enterovirus central nervous system infections are not well described. What is New: • Severe disease course, brain MRI abnormalities, and complications are not uncommon in newborns with Parechovirus and Enteroviruses central nervous system infections. • Hyper-ferritinemia may represent an additional diagnostic clue for Parechovirus infection and its monitoring is recommended.

Epidemiological and clinical evolution of multisystem inflammatory syndrome in children throughout the SARS-CoV-2 pandemic in a tertiary Italian children's hospital.

Multisystem inflammatory syndrome in children (MIS-C) is a potentially life-threatening disease temporally linked to SARS-CoV-2 whose incidence and clinical presentation may have been altered by the different SARS-CoV-2 variants and by vaccination. METHODS: We retrospectively collected the data of all MIS-C cases admitted to the Gaslini Children's Hospital, the hub for SARS-CoV-2 related diseases in Liguria region, Italy, from 01 October 2020, to 30 November 2022, evaluating the ratio between MIS-C cases and (1) COVID-19 paediatric cases in our region, (2) emergency department admissions and (3) emergency department febrile patients. We also compared MIS-C incidence in pre- post-vaccination periods. RESULTS: We observed a significant global decline in the incidence of MIS-Cover the four variant periods and after the starting of vaccination whereas clinical features, therapeutic management and severity did not significantly vary. CONCLUSIONS: In our setting, we demonstrated a significant decrease of MIS-C incidence according to the predominant variant and including not vaccinated children. Regardless of variant type, the patients showed similar phenotypes and severity throughout the pandemic. SARS-CoV-2 variants as well as immune protection after previous infections and/or vaccination may have interacted by playing different roles and reducing the incidence of MIS-C.

Individual, environmental and demographic factors may play a role in the prognosis of fatal and non-fatal paediatric drowning.

AIM: Drowning is a leading cause of unintentional death. Ongoing efforts are dedicated to preventing these tragic incidents. Our aim was to evaluate whether demographic, environmental and epidemiological characteristics of drowned children influence their prognosis. METHODS: Single-centre retrospective study spanning 12 years. Each patient's record included: age, sex, place of residence, presence of siblings, season of incident, location of event, associated trauma, loss of consciousness, need for cardiopulmonary resuscitation, intubation, admission to intensive care unit, length of stay and mortality. RESULTS: We enrolled 60 patients, with a mean age of 5.9 ± 3.4 years; 63.5% were male. Children who did not reside near the sea were significantly older than those who did (p = 0.01) and faced a higher risk of experiencing sea-related drowning (p = 0.05). No patients died. Loss of consciousness and need for cardiopulmonary resuscitation were recorded in 30 and 19 patients respectively. Seven patients sustained trauma. Only one patient requiring intubation. Pool-related drowning were associated with a higher incidence of needing cardiopulmonary resuscitation (p = 0.02). The need for cardiopulmonary resuscitation (p = 0.05) and the occurrence of trauma (p = 0.02) were identified as risk factors for a longer hospitalisation. CONCLUSION: Prevention and early initiation of cardiopulmonary resuscitation are essential for achieving a favourable prognosis. Identifying demographic and environmental risk factors may help identify other effective preventive measures.

Characteristics of COVID-19 patients up to 6 months of age admitted to a paediatric emergency department.

Very young age could be a potential risk factor for community-acquired severe acute respiratory syndrome coronavirus 2, due to immature immune systems. We retrospectively enrolled 39 infants up to 6 months of age who had presented to our tertiary Italian children's hospital emergency room between 9 March 2020 and 8 March 2021 and tested positive for the virus. Of those, 38 had a non-specific mild or asymptomatic clinical course and only one patient was admitted to intensive care with severe symptoms. We concluded that very young infants with COVID-19 had a generally favourable disease course.

The impact of COVID-19 lockdown on infectious diseases epidemiology: The experience of a tertiary Italian Pediatric Emergency Department.

INTRODUCTION: The aim of this study was to describe the rate and types of community-acquired respiratory infections observed in a pediatric ED during the SARS-CoV-2 related lockdown in Italy and to compare data with the same period of previous year. METHODS: A retrospective analysis of medical charts of patients arrived at the ED of Gaslini Children's Hospital from 10th March 2020 to 30th April 2019 and the same frame of 2020 were performed. We compared two groups by demographics, duration of fever before ED admission, triage code, number of patients hospitalized after ED evaluation. We calculated proportion and incidence rate for airborne infections, fever, and urinary tract infections (UTI), appendicitis, and gastroenteritis for control. RESULTS: 1362 children arrived at the ED during the lockdown compared to 5628 in the same period of 2019 (-75,8%). No difference was noticed (27.7% vs 28.4%) in the total amount of infectious episodes. A significant reduction in rate of incidence and proportion were observed for upper respiratory tract infections (21,4% vs 28%), otitis (2,6% vs 16,2%), streptococcal infections (0,5% vs 5,2%) and bronchiolitis (2,1% vs 5,7%). Conversely, FUO (27,8 vs 11,1%), infectious mononucleosis (2,6% vs 0,4%), UTI (7,4% vs 2,9%) and appendicitis (6,8% vs 1,1%) significantly increased. Median time from the onset of fever and arrival in ED was significantly lower in 2020 group. CONCLUSION: Our results demonstrated a reduction in community-acquired respiratory infections during the lockdown for COVID-19. The increase in rate of FUO and febrile conditions, together with the short time from fever onset and ED visit could be related to the fear for a SARS-CoV-2 infection.

Development of stratification criteria of green codes in a pediatric emergency department: a pilot study.

BACKGROUND: The aim of this study was to find stratification criteria in a group of children assigned to the green triage category at an emergency department (ED). METHODS: We analyzed a sample of patients admitted to the ED of Gaslini Children's Hospital in Genoa between February 2014 and January 2015 who had been given a green code on triage. We analyzed the following parameters: age, sex, nationality, reason for admission, number and type of the procedures performed, length of stay in the ED, destination on discharge, color code and diagnosis on discharge. RESULTS: Of the 2875 patients enrolled, 258 (8.97%) were hospitalized, 135 (4.70%) were placed in short intensive observation, 1609 (55.97%) were discharged from the ED without any intervention, 829 (28.83%) were discharged after undergoing procedures (blood tests, microbiology investigation, imaging, specialist evaluation) and 44 (1.5%) spontaneously left the ED. Among the patients who were hospitalized and those kept under short intensive observation, the most frequent discharge diagnosis was gastrointestinal disease; among those patients discharged with and without undergoing procedures, the most frequent diagnosis was respiratory disease. The mean age of patients admitted to hospital and of those discharged without undergoing procedures was 46 months, while the mean ages of patients kept under short intensive observation and of those discharged after undergoing procedures were 54 and 61 months, respectively. CONCLUSIONS: These preliminary results suggest that one of the main criteria of stratification of green codes on triage is the association between 2 variables: age and pathology.

The usefulness of point-of-care ultrasound in dehydrated patients in a pediatric emergency department.

BACKGROUNDS: Dehydration is among the most common causes of Pediatric Emergency Department admission; however, no clinical signs, symptoms, or biomarkers have demonstrated sufficient sensitivity, specificity, or reliability to predict dehydration. METHODS: We conducted a prospective, monocentric, observational study at Giannina Gaslini Hospital, a tertiary care pediatric hospital. Our study aimed to compare inferior vena cava ultrasound measurement with volume depletion biomarkers to understand if point-of-care ultrasound could help grade, evaluate, and better manage dehydration in children presenting to the pediatric emergency department. We enrolled patients under the age of 14 who required blood tests in the suspect of dehydration; for each patient, we collected values of venous pH, natremia, bicarbonatemia, uric acid, chloremia, and blood urea nitrogen. For each patient, we performed two ultrasound scans to calculate the Inferior Vena Cava/Aorta area ratio and to assess the IVC collapsibility index; moreover, we described the presence of the "kiss sign" (100% IVC walls collapsing during the inspiratory phase). RESULTS: Patients with the "kiss sign" (25/65 patients, 38.5% of the total) showed worse blood tests, in particular, uric acid levels (p = 0.0003), bicarbonatemia (p = 0.001) and natriemia (p = 0.0003). Moreover, patients with the "kiss sign" showed a high frequency of ≥ 2 pathological blood tests (p = 0.0002). We found no statistical significant difference when comparing the IVC/Ao ratio and IVC-CI with the considered blood tests. CONCLUSIONS: The "kiss sign" seems to be related to worse hydration state, whereas IVC/Ao and IVC-CI are not. In an emergency setting, where physicians must take diagnostic-therapeutic decisions quickly, the presence of the "kiss sign" in patients suspected to be dehydrated can be a helpful tool in their management.
