Background: Most children admitted to a paediatric intensive care unit (PICU) now survive because of improvements in care. Many studies have identified the psychological, functional, cognitive and social impact of PICU admission on a child and their family. However, expert recommendations on follow-up are lacking.

Introduction: In children, respiratory distress due to upper airway obstruction (UAO) is a common complication of extubation. The quantitative cuff-leak test (qtCLT) is a simple, rapid and non-invasive test that has not been extensively studied in children. The objective of the ongoing study whose protocol is reported here is to investigate how well the qtCLT predicts UAO-related postextubation respiratory distress in paediatric intensive care unit (PICU) patients.

Article Synopsis
  • A study evaluated the effectiveness of the BioFire Pneumonia plus Panel, a rapid-multiplex PCR assay, in diagnosing lower-respiratory-tract infections in critically ill pediatric patients compared to traditional culturing methods.
  • It included 36 patients with varying types of pneumonia and found that the PCR assay had high sensitivity (92%) and specificity (95%), with a notable agreement between the two methods (κ = 0.74).
  • The PCR assay also provided faster results (about 3.9 hours) than the reference method (about 60.5 hours), potentially leading to better-targeted antibiotic treatments and reduced unnecessary antibiotic use.

Background: Sickle cell disease (SCD) is one of the most frequent inherited diseases in the world. Over the last decades, in high-income countries, an important decrease in mortality have been observed due to the improvement of care. However, children with SCD can become critically ill and require admission in Pediatric Intensive Care Units (PICU).

PEDIATRIC NECROTIZING SOFT-TISSUE INFECTIONS. Necrotizing soft-tissue infections (NSTI) include necrotizing forms of fasciitis, myositis, and cellulitis. In children, these are extremely rare conditions with an estimated annual incidence of less than 0.

Congenital central hypoventilation syndrome (CCHS) is an autosomal dominant disease that is caused by heterozygous mutations in the paired-like homeobox 2B gene (PHOX2B). Madani et al. described an abnormally high degree of not only central apnea but also obstructive and mixed apnea in Phox2bnewborn mice.

Article Synopsis
  • Toxic shock syndrome (TSS) is a serious but rare illness that can lead to significant health problems, especially in children, and the study aimed to test the effectiveness and safety of intravenous immunoglobulin (IG) therapy compared to a control treatment in pediatric patients.
  • The study involved a randomized clinical trial with 28 participants aged 1 month to 18 years, assessing the feasibility of the trial based on inclusion rates, protocol compliance, and data completeness over a follow-up period of one year.
  • The results indicated that while the trial was feasible with a high inclusion rate and low missing data, there was no significant difference in clinical outcomes between the IG and control groups, although more adverse events were noted in the control group.

Background: Use of continuous renal replacement therapy in children receiving anti-infective drugs may lead to inappropriate concentrations with risks related to treatment failure, toxicity and emergence of multidrug-resistant bacteria. We aimed to describe anti-infective prescribing practices in critically ill children undergoing continuous renal replacement therapy.

Methods: An online survey to assess continuous renal replacement therapy, anti-infective prescribing and therapeutic drug monitoring practices was sent by e-mail to physicians working in pediatric intensive care units through the French-speaking Group of Pediatric Intensive Care and Emergency medicine (GFRUP).

Background: Staphylococcus aureus (SA) is one of the main pathogens responsible for healthcare-associated infection (HCAI) in pediatrics. The aim of this study was to describe the prevalence of SA-HCAI among colonized patients and the factors associated with it in the pediatric intensive care unit (PICU).

Methods: We designed a 6-year retrospective cohort study of a PICU in a French university children's hospital including all children admitted to the PICU from January 1, 2011, to December 31, 2016, who had SA colonization on PICU admission.

Background: Hyperammonemic encephalopathy caused by spp. and infection has been reported in immunocompromised patients undergoing lung transplant, but data are scarce in patients with hematological malignancies.

Case Presentation: We describe the cases of 3 female patients aged 11-16 years old, developing initially mild neurologic symptoms, rapidly evolving to coma and associated with very high ammonia levels, while undergoing intensive treatment for acute leukemia (chemotherapy: 2 and hematopoietic stem cell transplant: 1).

Article Synopsis
  • The study focused on managing children with Plasmodium falciparum hyperparasitemia (≥10%) in French hospitals, as per pediatric guidelines, aiming to understand their clinical course and treatment approaches.
  • Conducted over eight hospitals from 2007 to 2014, the research analyzed data from 61 non-immune children, comparing outcomes of those treated in pediatric intensive care units versus other settings.
  • Findings revealed that most children (77%) were treated outside intensive care, primarily with oral antimalarial medication, with no reported deaths, highlighting the importance of thorough clinical evaluation and hospital supervision for effective management.

Objectives: This study aimed to assess the incidence of amikacin plasma peak concentration (C) below 60 mg·L in critically ill children receiving an amikacin dosing regimen of 30 mg kg·day. Secondary objectives were to identify factors associated with low C and to assess the incidence of acute kidney injury (AKI).

Methods: A retrospective observational study was performed in two French pediatric intensive care units.

Tisagenlecleucel therapy has shown promising efficacy for relapsed/refractory (R/R) B-cell precursor acute lymphoblastic leukemia (BCP-ALL). However, relapses occur in 30-50% of patients. Determinants for CD19 versus CD19 relapses are poorly characterized.

Objectives: A protocol has been written and distributed in May 2017 to all prescribers in a pediatric hospital to standardize and to secure the prescriptions of enoxaparin and tinzaparin considered as two high risk medications. The aim of this study is to evaluate the impact of the protocol on those prescriptions in a pediatric population.

Methods: This is a monocentric retrospective study comparing prescriptions of this two low-molecular-weight heparins for patients under 18 years old in 2016 and 2018, thus before and after the protocol redaction.

CAR-T cell-related encephalopathy syndrome (CRES) reflects the potential neurotoxicity of this therapeutic approach and must be considered in the presence of any neurological symptom after the infusion of the CAR-T. This is the second most common adverse event under this therapy and its incidence varies between 12 and 55%. The median time of the onset of the first neurologic symptoms is 4days after CAR-T infusion.

Since the 2007 French guidelines on imported Falciparum malaria, the epidemiology, treatment, and prevention of malaria have changed considerably requiring guidelines for all Plasmodium species to be updated. Over the past decade, the incidence of imported malaria has decreased in all age groups, reflecting the decrease in the incidence of malaria in endemic areas. The rates of severe pediatric cases have increased as in adults, but fatalities are rare.

The cytokine release syndrome (CRS) is the most common complication after adoptive immunotherapies such as chimeric antigen receptor T cells (CAR-T). The incidence varies from 30 to 100% depending on the CAR-T construct, cell doses and the underlying disease. Severe cases may involve 10 to 30% of patients.

The "Praecox Feeling" (PF) is a classical concept referring to a characteristic feeling of bizarreness experienced by a psychiatrist while encountering a person with schizophrenia. Although the PF used to be considered a core symptom of the schizophrenia spectrum, it fell into disuse since the spread of operationalized diagnostic methods (Diagnostic and Statistical Manual of Mental Disorders/International Classification of Diseases systems). In contemporary research on schizophrenia, it remains largely unaddressed.
