Hydroxyurea in Sickle Cell Disease and Invasive Bacterial Infections: A Case-Control Study.

Hydroxyurea decreases painful events among children with sickle cell disease (SCD) but could increase the risk of infections in treated patients through leucopenia. We performed a case-control study, comparing hydroxyurea treatment for SCD in cases with an invasive bacterial infection and in controls without infection. No difference was found.

Assessment of adherence to the 2020 Surviving Sepsis Campaign guidelines for fluid resuscitation in children with suspected septic shock in paediatric emergency departments: a prospective multicentre study.

Background: Paediatric sepsis is the leading cause of death in children under 5 years. No studies have evaluated the application of the Surviving Sepsis Campaign 2020 (SSC-2020) guidelines in paediatric emergency departments (PEDs).

Objective: To assess physician adherence to the SSC-2020 fluid resuscitation guidelines in children with suspected septic shock in PEDs.

Invasive Bacterial Infections in Children With Sickle Cell Disease: 2014-2019.

Background: Children with sickle cell disease (SCD) are at a high risk of invasive bacterial infections (IBI). Universal penicillin prophylaxis and vaccination, especially against Streptococcus pneumoniae, have deeply changed its epidemiology. Analysis of IBI in children with SCD in a post-13-valent pneumococcal vaccine era is limited.

Incidence of Acute Chest Syndrome in Children With Sickle Cell Disease Following Implementation of the 13-Valent Pneumococcal Conjugate Vaccine in France.

Importance: Acute chest syndrome (ACS) is one of the leading acute severe complications of sickle-cell disease (SCD). Although Streptococcus pneumoniae (S pneumoniae) is highly prevalent in children with SCD, its precise role in ACS is unclear. The efficacy of 13-valent pneumococcal conjugate vaccine (PCV13) implementation on ACS is still unknown.

Medical check-up of newly arrived unaccompanied minors: A dedicated pediatric consultation service in a hospital.

Background And Aims: Healthcare for the increasing number of migrants in Europe, and particularly of unaccompanied minors (UMs) seeking asylum, has become a major challenge. We aimed to describe the health issues of UMs managed in a dedicated pediatric consultation service in a care center in Paris.

Methods: All UMs attending a dedicated migrant medical consultation service in Robert Debré Hospital, Paris, France, were included in a single-center retrospective observational study from September 1, 2017, to September 30, 2018.

[Medication and children: Practical situations to address the risks].

Medications are an important source of intoxication or misuse in the pediatric population. It is therefore important to raise parents' awareness on this point. To do so, a team of professionals has set up an e-learning, presented in the form of a slide show.

Contribution of Serological Rapid Diagnostic Tests to the Strategy of Contact Tracing in Households Following SARS-CoV-2 Infection Diagnosis in Children.

The contact tracing and isolation of contagious individuals are cornerstones in the control of the COVID-19 pandemic. Strategies to identify household contacts who should be isolated around index children that tested positive for SARS-CoV-2 remain to be clarified. We aimed to compare contact tracing strategies around an index child positive for SARS-CoV-2 using serological rapid diagnostic testing (RDT, chromatography immunoassay).

[COVID-19 in children: SARS-CoV-2-related inflammatory multisystem syndrome mimicking Kawasaki disease].

SARS-CoV-2 pandemics is characterized by a high level of infectivity and a high mortality among adults at risk (older than 65 years, obesity, diabetes, systemic hypertension). Following a common viral pneumonia, a multisystem inflammatory syndrome sometimes occurs, including an Acute Respiratory Distress Syndrome (ARDS) carrying a high mortality. Unlike most common respiratory viruses, children seem less susceptible to SARS-CoV-2 infection and generally develop a mild disease with low mortality.

Factors Associated With Severe SARS-CoV-2 Infection.

Background: Initial reports on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections in children suggested that very young age and comorbidities may increase risk of severe evolution, but these findings remained to be confirmed. We aimed to analyze the clinical spectrum of hospitalized pediatric SARS-CoV-2 infection and predictors of severe disease evolution.

Methods: We conducted a French national prospective surveillance of children hospitalized with SARS-CoV-2 infection.

Risks of severe hyponatremia in children receiving hypotonic fluids.

Intravenous fluids are frequently used in hospitalized children. Hypotonic fluids have been the standard of care in pediatrics for many years. This might be explained by the empiricism of early recommendations favoring fluids with dextrose, but an insufficient amount of sodium.

Systematic Severe Acute Respiratory Syndrome Coronavirus 2 Screening at Hospital Admission in Children: A French Prospective Multicenter Study.

To assess the relevance of systematic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) screening of all children admitted to hospital, we conducted a prospective multicenter study including 438 consecutive hospitalized children. A symptom-based SARS-CoV-2 testing strategy failed to identify 45% (95% confidence interval, 24%-68%) of hospitalized children infected by SARS-CoV-2. To limit intrahospital transmission, a systematic screening of children admitted to hospital should be considered.

Emergence of Kawasaki disease related to SARS-CoV-2 infection in an epicentre of the French COVID-19 epidemic: a time-series analysis.

Background: Kawasaki disease is an acute febrile systemic childhood vasculitis, which is suspected to be triggered by respiratory viral infections. We aimed to examine whether the ongoing COVID-19 epidemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is associated with an increase in the incidence of Kawasaki disease.

Methods: We did a quasi-experimental interrupted time series analysis over the past 15 years in a tertiary paediatric centre in the Paris region, a French epicentre of the COVID-19 outbreak.

Management of Febrile Urinary Tract Infection With or Without Bacteraemia in Children: A French Case-Control Retrospective Study.

Febrile urinary tract infections (FUTIs) are common among children, and are associated with a bacteraemia between 4 and 7% of cases. No data is available concerning the management of children with a bacteraemic FUTI. To compare the antibiotic treatment (parenteral and total duration) among children with bacteraemic and non-bacteraemic FUTIs, and the mean hospital length of stay (LOS); to describe clinical, microbiological and imaging features of children with bacteraemic and non-bacteraemic FUTIs and observed management modifications when the blood culture was positive.

Respiratory pathogens and acute chest syndrome in children with sickle cell disease.

Background: Acute chest syndromes (ACS) may be associated with upper respiratory tract infections, but the epidemiology of viral and intracellular respiratory pathogens in children with sickle cell disease (SCD) is not precisely known. The aim of this study was to describe the epidemiology of viral and intracellular respiratory pathogens in children with SCD presenting with fever and/or ACS.

Materials And Methods: An observational, prospective, single-centre cohort study with nested case-control analysis was conducted on children with SCD admitted from October 2016 to October 2017 for fever and/or ACS to the paediatric department of Robert Debré university hospital, Paris, France.

Nitrous oxide and vitamin B12 in sickle cell disease: Not a laughing situation.

Nitrous oxide (NO) is widely used as an anesthetic or an analgesic. NO prolonged and recurrent administration is known to affect vitamin B12 metabolism with subsequent clinical consequences. We report herein the case of a 13-year-old girl with sickle cell disease exhibiting severe neurological and biochemical signs of functional vitamin B12 deficiency due to prolonged and repeated exposure to NO.

Implementation of a large-scale simulation-based cardiovascular clinical examination course for undergraduate medical students - a pilot study.

Background: We report the implementation of a large-scale simulation-based cardiovascular diagnostics course for undergraduate medical students.

Methods: A simulation-based course was integrated into the curriculum of second-year medical students (> 400 students/year). The first session aimed at teaching cardiac auscultation skills on mannequins and the second at teaching blood pressure measurement, peripheral arterial examination, and the clinical examination of heart failure in a technical skill-based manner and in a scenario.

Enteric fever among children: 50 cases in a French tertiary care centre.

Background: Enteric fever in France is primarily travel-associated. Characteristics of paediatric cases are scarce and information from field studies in endemic countries might not be generalizable to non-endemic countries.

Methods: In this retrospective study, we reviewed all cases of typhoid and paratyphoid fever treated in a French paediatric tertiary care centre from 1993 to 2015.

Kawasaki disease: abnormal initial echocardiogram is associated with resistance to IV Ig and development of coronary artery lesions.

Background: Kawasaki disease (KD) is an acute febrile systemic vasculitis that affects small and medium blood vessels. Intensified treatments for the most severely affected patients have been proposed recently, and the early identification of KD patients at high risk for coronary artery aneurysms (CAA) is crucial. However, the risk scoring systems developed in Japan have not been validated in European populations, and little data is available concerning the link between initial echocardiogram findings other than high z-scores and cardiac prognosis.

Likely False-Positive Pneumococcal Antigen Test BinaxNOW Due to Parvimonas micra: A Four-Case Series.

We retrospectively report four cases from two hospitals of nonpneumococcal pleural empyema with a likely false-positive result on the pneumococcal antigen test BinaxNOW (PATB) (Alere) performed in pleural fluid samples in patients with aspiration pneumonia risk factors. To determine whether the positive reaction was due to cross-reactivity, we separately tested the isolates from the pleural fluid samples, along with collection and reference strains. All patients had polymicrobial aerobic and anaerobic positive cultures, including Parvimonas micra in every case.
