Article Synopsis
  • In September 2023, France launched a national immunization campaign using nirsevimab, a monoclonal antibody targeting respiratory syncytial virus (RSV).
  • A case-control study was conducted with 288 infants from 20 pediatric intensive care units (PICUs) to assess the effectiveness of nirsevimab against severe RSV bronchiolitis.
  • The study found nirsevimab to have an effectiveness of 75.9% in the main analysis, with higher estimates of 80.6% and 80.4% in sensitivity analyses, confirming its efficacy observed in previous clinical trials.

Objective: It is now well established that post-intensive care syndrome is frequent in critically ill children after discharge from the pediatric intensive care unit (PICU). Nevertheless, post-intensive care follow-up is highly heterogenous worldwide and is not considered routine care in many countries. The purpose of this viewpoint was to report the reflections of the French PICU society working group on how to implement post-PICU follow-up.

Background: During neonatal and paediatric high-flow nasal cannula therapy, optimising the flow setting is crucial for favourable physiological and clinical outcomes. However, considerable variability exists in clinical practice regarding initial flows and subsequent adjustments for these patients. Our review aimed to summarise the impact of various flows during high-flow nasal cannula treatment in neonates and children.

Aim: To compare the efficacy of intravenous clonazepam (CLZ) for the initial management of convulsive status epilepticus (CSE) in children as a function of the first-line in-hospital dose used.

Method: This monocentric retrospective study included children who received a first dose of CLZ for CSE at Montpellier University Hospital, France, between January 2016 and June 2019. Data from medical records (clinical, treatment, course) were collected and compared as a function of the first CLZ dose used.

Introduction: High-flow nasal cannula (HFNC) is commonly used as first step respiratory support in infants with moderate-to-severe acute viral bronchiolitis (AVB). This device, however, fails to effectively manage respiratory distress in about a third of patients, and data are limited on determinants of patient response. The respiratory rate-oxygenation (ROX) index is a relevant tool to predict the risk for HFNC failure in adult patients with lower respiratory tract infections.

Objective: To reach a consensus on the definition and modalities of weaning from noninvasive ventilation in acute settings.

Design: A modified Delphi survey using closed and open-ended questions.

Setting: Three rounds of consensus determination were sent via electronic mail survey to 33 experts.

Objective: To assess whether music therapy (MT) is effective to reduce pain during daily personal hygiene care (DPHC), a procedure performed in all patients in a pediatric intensive care unit.

Methods: Fifty critically ill children were enrolled in a crossover controlled clinical trial with random ordering of the intervention, that is, passive MT, and standard conditions, and blind assessment of pain on film recordings. The primary outcome was variation of the Face Legs Activity Cry Consolability (FLACC) score (range, 0-10) comparing before and during DPHC.

Objectives: To describe the policies about parent visiting and involvement in care during admission to French PICUs.

Design: A structured questionnaire was emailed to the chief of each of 35 French PICUs. Data about visiting policies, involvement in care, evolution of policies, and general characteristics were collected from April 2021 to May 2021.

Background: Aromatic l-amino acid decarboxylase deficiency (AADCD) is a rare, early-onset, dyskinetic encephalopathy mostly reflecting a defective synthesis of brain dopamine and serotonin. Intracerebral gene delivery (GD) provided a significant improvement among AADCD patients (mean age, ≤6 years).

Objective: We describe the clinical, biological, and imaging evolution of two AADCD patients ages >10 years after GD.

Context: Laryngoscopy is frequently required in neonatal intensive care. Awake laryngoscopy has deleterious effects but practice remains heterogeneous regarding premedication use. The goal of this statement was to provide evidence-based good practice guidance for clinicians regarding premedication before tracheal intubation, less invasive surfactant administration (LISA) and laryngeal mask insertion in neonates.

Purpose: We present guidelines for the management of infants under 12 months of age with severe bronchiolitis with the aim of creating a series of pragmatic recommendations for a patient subgroup that is poorly individualized in national and international guidelines.

Methods: Twenty-five French-speaking experts, all members of the Groupe Francophone de Réanimation et Urgence Pédiatriques (French-speaking group of paediatric intensive and emergency care; GFRUP) (Algeria, Belgium, Canada, France, Switzerland), collaborated from 2021 to 2022 through teleconferences and face-to-face meetings. The guidelines cover five areas: (1) criteria for admission to a pediatric critical care unit, (2) environment and monitoring, (3) feeding and hydration, (4) ventilatory support and (5) adjuvant therapies.

Article Synopsis
  • - This study focused on 15 infants under a year old in intensive care who were suspected to have genetic conditions and underwent rapid trio exome sequencing (rES) from April 2019 to April 2021.
  • - The key finding was that results from rES were available to parents within 16 days for 86% of the participants, and 40% received a confirmed diagnosis.
  • - The study highlights the potential of rES to enhance medical care for critically ill infants, despite some patients not receiving a diagnosis and a few passing away before results were available.

Aim: The aim of this study was to assess the prevalence of discomfort in infants with severe bronchiolitis supported by noninvasive ventilation and to identify its potential risk factors.

Methods: A single-centre retrospective observational study. Discomfort was assessed using the EDIN (Echelle de Douleur et d'Inconfort du Nouveau-né) scale.

Less invasive surfactant administration (LISA) has become increasingly popular in neonatal intensive care units (NICUs), but there are currently no guidelines for the premedication prior to this procedure. The aim of this observational study was to compare the efficacy and tolerance of intravenous administrations of ketamine and propofol before LISA in neonates born before 30 weeks of gestational age (GA). The primary outcome was requirement of intubation within 2 h of the procedure.

Objective: To evaluate the association of early continuous infusions of opioids and/or midazolam with survival and sensorimotor outcomes at age 2 years in very premature infants who were ventilated.

Study Design: This national observational study included premature infants born before 32 weeks of gestation intubated within 1 hour after birth and still intubated at 24 hours from the French EPIPAGE 2 cohort. Infants only treated with bolus were excluded.

Objective: To assess the inspiratory demand in young infants with acute viral bronchiolitis to provide a physiological basis for initial flow setting for patients supported with high flow nasal cannula.

Study Design: Prospective study in 44 infants up to 6 months old with acute viral bronchiolitis, admitted to a pediatric intensive care unit from November 2017 to March 2019. Airflow measurements were performed using spirometry.

Article Synopsis
  • Heterozygous mutations in the KMT2B gene are linked to early-onset dystonia (DYT28), featuring motor problems that start locally and can spread throughout the body, particularly affecting the face and neck.
  • A study of 53 patients with KMT2B mutations revealed new disease presentations and identified various health issues, such as growth retardation and endocrine disorders, as well as a higher impact on patients with more severe genetic variants.
  • Patients who underwent deep brain stimulation for severe dystonia showed significant improvement in motor function and disability over time, with more than half experiencing over 30% improvement at the one-year mark.

Working Hypothesis: No information regarding the weaning practices is currently available and there may be a wide variability of strategies.

Study Design: A cross-sectional electronic survey.
