RESUMEN
We aimed to identify the spectrum of disease in children with COVID-19, and the risk factors for admission in paediatric intensive care units (PICUs). We conducted a multicentre, prospective study of children with SARS-CoV-2 infection in 76 Spanish hospitals. We included children with COVID-19 or multi-inflammatory syndrome (MIS-C) younger than 18 years old, attended during the first year of the pandemic. We enrolled 1200 children. A total of 666 (55.5%) were hospitalised, and 123 (18.4%) required admission to PICU. Most frequent major clinical syndromes in the cohort were mild syndrome (including upper respiratory tract infection and flu-like syndrome, skin or mucosae problems and asymptomatic), 44.8%; bronchopulmonary syndrome (including pneumonia, bronchitis and asthma flare), 18.5%; fever without a source, 16.2%; MIS-C, 10.6%; and gastrointestinal syndrome, 10%. In hospitalised children, the proportions were 28.5%, 25.7%, 16.5%, 19.1% and 10.2%, respectively. Risk factors associated with PICU admission were age in months (OR: 1.007; 95% CI 1.004 to 1.01), MIS-C (OR: 14.4, 95% CI 8.9 to 23.8), chronic cardiac disease (OR: 4.8, 95% CI 1.8 to 13), asthma or recurrent wheezing (OR: 2.5, 95% CI 1.2 to 5.2) and after excluding MIS-C patients, moderate/severe liver disease (OR: 8.6, 95% CI 1.6 to 47.6). However, asthmatic children were admitted into the PICU due to MIS-C or pneumonia, not due to asthma flare.Conclusion: Hospitalised children with COVID-19 usually present as one of five major clinical phenotypes of decreasing severity. Risk factors for PICU include MIS-C, elevation of inflammation biomarkers, asthma, moderate or severe liver disease and cardiac disease. What is Known: ⢠All studies suggest that children are less susceptible to serious SARS-CoV-2 infection when compared to adults. Most studies describe symptoms at presentation. However, it remains unclear how these symptoms group together into clinically identifiable syndromes and the severity associated with them. What is New: ⢠We have gathered the primary diagnoses into five major syndromes of decreasing severity: MIS-C, bronchopulmonary syndrome, gastrointestinal syndrome, fever without a source and mild syndrome. Classification of the children in one of the syndromes is unique and helps to assess the risk of critical illness and to define the spectrum of the disease instead of just describing symptoms and signs.

INTRODUCTION: An increase in cases of pertussis, mainly in young infants, has been reported in the last few years. The clinical presentation of this disease is very similar to that produced by respiratory syncytial virus (RSV), which makes the diagnosis difficult. OBJECTIVE: To compare the clinical and epidemiological characteristics between Bordetella pertussis and RSV infections in infants admitted to hospital. MATERIAL AND METHODS: An analytical matched case-control study was conducted during the period 2008-2011. Cases were defined as infants admitted with pertussis confirmed by PCR in nasopharyngeal aspirate. Each case was matched by age, sex and date of admission to two controls defined as patients with RSV infection detected by immunochromatography in nasal aspirate. Demographic, clinical, laboratory data were compared. RESULTS: Seventy eight patients (26 cases of pertussis and 52 controls RSV+) were included. Sociodemographic characteristics were similar in both groups. Cases had more days of symptoms prior to admission, longer hospital stays, and increased frequency of epidemic family environment. Apnoea and cyanosis were more frequent. Cases of pertussis were more likely to have apnoea, cyanosis, and lymphocytosis while RSV infections had more frequent fever, vomiting and respiratory distress. CONCLUSIONS: The clinical presentations of pertussis and RSV infection are similar, but there are some characteristics that can help to distinguish between them.

INTRODUCTION: Endemic coronaviruses have been found in acute bronchiolitis, mainly as a coinfecting virus. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been responsible for respiratory illness in hospitalized children. The characteristics of patients with bronchiolitis have not been extensively described. METHODS: Cross-sectional study of patients with bronchiolitis and SARS-CoV-2 infection enrolled in a prospective multicenter cohort of children hospitalized with COVID-19 in Spain from March 1, 2020 to February 28, 2021. RESULTS: Twelve of 666 children infected with SARS-CoV-2 who required hospital admission met the diagnostic criteria for bronchiolitis (1.8%). Median age was 1.9 months (range: 0.4-10.1). Six cases had household contact with a confirmed or probable COVID-19 case. Main complaints were cough (11 patients), rhinorrhea (10), difficulty breathing (8), and fever (8). Eleven cases were classified as mild or moderate and one as severe. Laboratory tests performed in seven patients did not evidence anemia, lymphopenia, or high C-reactive protein levels. Chest X-rays were performed in six children, and one case showed remarkable findings. Coinfection with metapneumovirus was detected in the patient with the most severe course; Bordetella pertussis was detected in another patient. Seven patients required oxygen therapy. Albuterol was administered in four patients. One patient was admitted to the pediatric intensive care unit. Median length of admission was 4 days (range: 3-14). No patient died or showed any sequelae at discharge. Two patients developed recurrent bronchospasms. CONCLUSION: SARS-CoV-2 infection does not seem to be a main trigger of severe bronchiolitis, and children with this condition should be managed according to clinical practice guidelines.

OBJECTIVES: To evaluate the performance of oral saliva swab (OSS) reverse transcription PCR (RT-PCR) compared with RT-PCR and antigen rapid diagnostic test (Ag-RDT) on nasopharyngeal swabs (NPS) for SARS-CoV-2 in children. DESIGN: Cross-sectional multicentre diagnostic study. SETTING: Study nested in a prospective, observational cohort (EPICO-AEP) performed between February and March 2021 including 10 hospitals in Spain. PATIENTS: Children from 0 to 18 years with symptoms compatible with Covid-19 of ≤5 days of duration were included. Two NPS samples (Ag-RDT and RT-PCR) and one OSS sample for RT-PCR were collected. MAIN OUTCOME: Performance of Ag-RDT and RT-PCR on NPS and RT-PCR on OSS sample for SARS-CoV-2. RESULTS: 1174 children were included, aged 3.8 years (IQR 1.7-9.0); 73/1174 (6.2%) patients tested positive by at least one of the techniques. Sensitivity and specificity of OSS RT-PCR were 72.1% (95% CI 59.7 to 81.9) and 99.6% (95% CI 99 to 99.9), respectively, versus 61.8% (95% CI 49.1 to 73) and 99.9% (95% CI 99.4 to 100) for the Ag-RDT. Kappa index was 0.79 (95% CI 0.72 to 0.88) for OSS RT-PCR and 0.74 (95% CI 0.65 to 0.84) for Ag-RDT versus NPS RT-PCR. CONCLUSIONS: RT-PCR on the OSS sample is an accurate option for SARS-CoV-2 testing in children. A less intrusive technique for younger patients, who usually are tested frequently, might increase the number of patients tested.

Rothia mucilaginosa, previously known as Stomatococcus mucilaginosus, is a Gram-positive coccus that is part of the oropharyngeal microbiota and upper respiratory tract. It is mainly related to infections in immunosuppressed patients. Given its complex microbiological identification, its prevalence may be underestimated. We describe in this article a case of bacteraemia by Rothia in an immunocompetent paediatric patient without epidemiological or medical relevant history. In the available literature no cases of bacteraemia by Rothia mucilaginosa in immunocompetent paediatric patients have been reported. Given the characteristics of our patient, the publication of this case is of interest. Once the diagnosis of Rothia mucilaginosa has been made, the correct functioning of the immune system of the patient should be checked.

BACKGROUND: We assessed the effectiveness of a handwashing program using hand sanitizer to prevent school absenteeism due to upper respiratory infections (URIs). METHODS: This was a randomized, controlled, and open study on a sample of 1341 children 4-12 years old, attending 5 state schools in Almería (Spain), with an 8-month follow-up. The experimental group (EG) washed their hands with soap and water, together with using hand sanitizer, and the control group followed their usual handwashing procedures. Absenteeism rates due to URIs were compared between the 2 groups through a multivariate Poisson regression analysis. The percent of days missed in both groups were compared with a z test. RESULTS: Overall, 1271 cases of school absenteeism due to URIs were registered. Schoolchildren from the EG had a 38% lower risk of absenteeism due to URIs, incidence rate ratio: 0.62, 95% confidence interval: 0.55-0.70, and a decrease in absenteeism of 0.45 episodes/child/academic year, p < .001. Pupils missed 2734 school days due to URIs and the percentage of days absent was significantly lower in the EG, p < .001. CONCLUSIONS: Use of hand sanitizer plus handwashing with soap accompanied by educational support is an effective measure to reduce absenteeism due to URIs.

BACKGROUND: Staphylococcus aureus is a major cause of bacteremia in children and is associated with high morbidity. Complete data are lacking on the incidence, related risk factors and mortality associated with this infection. METHODS: Descriptive study including patients younger than 16 years admitted to a tertiary reference hospital, with blood cultures exclusively positive for S. aureus. Four study periods were established: period 1, 1995-1999; period 2, 2000-2002; period 3, 2006-2008 and period 4, 2010-2012. RESULTS: In total, 269 episodes of S. aureus bacteremia (SAB) occurred in 242 patients. Over the total time studied, the incidence increased from 1.3 to 3.3 cases per 1000 patients hospitalized (relative risk: 2.71; 95% confidence interval: 1.85-3.95) and mortality decreased from 18% to 6% (P = 0.008). There were no differences in the resistance patterns of S. aureus strains. The prevalence of methicillin-resistant S. aureus (MRSA) increased from 3% to 13% between periods 1 and 2 and decreased from 14% to 3% between periods 3 and 4 (P = 0.011). The 30-day cumulative mortality was 3.3%, and the SAB-related mortality was 1.5%. Nosocomial acquisition and age 12-16 years were factors independently related with death on multivariate analysis. CONCLUSIONS: The incidence of SAB tripled during the years studied but remained stable in the last period. Antimicrobial resistances did not increase. Although a decrease in mortality was documented, approximately half the 30-day cumulative mortality was caused by SAB.

BACKGROUND: Acute gastroenteritis (AGE) is one of the most common diseases among children and an important cause of school absenteeism. The aim of this study was to assess the effectiveness of a handwashing program using hand sanitizers for the prevention of school absenteeism due to AGE. METHODS: A randomized, controlled and open study of a sample of 1341 children between 4 and 12 years of age, attending 5 state schools in Almería (Spain), with an 8-month follow up (academic year). The experimental group (EG) washed their hands with soap and water, complementing this with the use of a hand sanitizer, and the control group (CG) followed the usual handwashing procedure. Absenteeism rates due GI were compared between the 2 groups through the multivariate Poisson regression analysis. Percent days absent in both groups were compared with a Z-test. RESULTS: 446 cases of school absenteeism due to AGE were registered. The school children from the EG had a 36% lower risk of absenteeism due to AGE (IRR: 0.64, 95% confidence interval: 0.52-0.78) and a decrease in absenteeism of 0.13 episodes/child/academic year (0.27 of EG vs 0.40 CG/episodes/child/academic year, P < 0.001). Pupils missed 725 school days due to AGE and absent days was significantly lower in the EG (EG: 0.31%, 95% confidence interval: 0.28-0.35 vs. CG: 0.44%, 95% confidence interval: 0.40-0.48, P < 0.001). CONCLUSIONS: The use of hand sanitizer as a complement to handwashing with soap is an efficient measure to reduce absent days and the number of school absenteeism cases due to AGE.

Deficiency in the interleukin12/INFgamma pathway is a genetic condition that predisposes to some infections, including nontuberculous mycobacteria infection and extraintestinal salmonellosis. We report 2 cases in sisters who were diagnosed with a genetic defect caused by a new mutation in Interleukin-12 receptor ß1 chain (IL12Rß1) leading to different clinical presentations and responses to therapy.

BACKGROUND: School absenteeism because of infections is one of the most important problems facing both public and private primary schools. The aim of the study was to assess the impact of infections on school absenteeism and their reduction with a handwashing program using hand sanitizer. METHODS: The study was an 8-month-long, randomized, controlled open study (N = 1,609 children, aged 4-12 years old) at 5 state schools in Almeria (Spain). The experimental group (EG) washed their hands with soap and water, complemented with the use of hand sanitizer, and the control group (CG) followed the usual handwashing procedure. The total number of episodes and days missed as well as those because of upper respiratory infections and gastrointestinal infections were compared in both groups with a Z-test. RESULTS: The students were absent 12,386 days in 7,945 episodes. The incidence of total absent episodes and percent of missed days, including those because of upper respiratory infections and gastrointestinal infections, were significantly lower in the EG than the CG (P < .001), and this was maintained through the flu pandemic period. CONCLUSION: School absenteeism because of infections in schools is reduced when a hand hygiene program utilizing sanitizing gels is properly carried out, especially during the flu season.
