Implications of sedation during the use of noninvasive ventilation in children with acute respiratory failure (SEDANIV Study).

Background: The objective of this study was to analyze the effects of sedation administration on clinical parameters, comfort status, intubation requirements, and the pediatric intensive care unit (PICU) length of stay (LOS) in children with acute respiratory failure (ARF) receiving noninvasive ventilation (NIV).

Methods: Thirteen PICUs in Spain participated in a prospective, multicenter, observational trial from January to December 2021. Children with ARF under the age of five who were receiving NIV were included.

Characteristics and management of patients with SARS-CoV2 infection admitted to pediatric intensive care units: Data analysis of the Spanish national multicenter registry.

Introduction: The purpose of this study is to describe the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV2) disease characteristics and management in children admitted to the pediatric intensive care units (PICU).

Methods: The present study was based on a national multicentric prospective registry including PICU patients with SARS-CoV2 infection or symptoms of multisystem inflammatory syndrome in children (MIS-C).

Results: A total of 298 patients were admitted to 41 different Spanish PICUs.

Treatments for multi-system inflammatory syndrome in children - discharge, fever, and second-line therapies.

Scarce evidence exists about the best treatment for multi-system inflammatory syndrome (MIS-C). We analyzed the effects of steroids, intravenous immunoglobulin (IVIG), and their combination on the probability of discharge over time, the probability of switching to second-line treatment over time, and the persistence of fever 2 days after treatment. We did a retrospective study to investigate the effect of different treatments on children with MIS-C from 1 March 2020 to 1 June 2021.

Evaluation of the PECARN rule for traumatic brain injury applied to infants younger than 3 months and creation of a modified, age-specific rule.

Unlabelled: Infants < 3 months with minor head trauma (MHT) are a particularly vulnerable group, though few studies have focused specifically on these patients. We aimed to evaluate the application of the PECARN prediction rule, designed for clinically important traumatic brain injury (ciTBI) in children < 2 years in infants < 3 months, and create a specific prediction rule for this population. We conducted a prospective multicenter observational study in 13 pediatric emergency departments (PEDs) in Spain.

Safety and Acceptance of COVID-19 Vaccination After Multisystem Inflammatory Syndrome in Children (MIS-C) in Spain.

In this cohort of 42 adolescents with a previous multisystem inflammatory syndrome (MIS-C) diagnosis, 32 (76.2%) were vaccinated with COVID-19 vaccines, with a low incidence of relevant adverse events. More importantly, no new MIS-C or myocarditis occurred after a median of 10 weeks (range 5.

Ten years since the introduction of therapeutic hypothermia in neonates with perinatal hypoxic-ischaemic encephalopathy in Spain.

Introduction: More than a decade has passed since therapeutic hypothermia (TH) was introduced in Spain; this is the only neuroprotective intervention that has become standard practice in the treatment of perinatal hypoxic-ischaemic encephalopathy (HIE). This article aims to provide a current picture of the technique and to address the controversies surrounding its use.

Development: In the last 10 years, TH has been successfully implemented in the vast majority of tertiary hospitals in Spain, and more than 85% of newborns with moderate or severe HIE currently receive the treatment.

Clinical spectrum of COVID-19 and risk factors associated with severity in Spanish children.

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.

Dynamics of Reverse Transcription-Polymerase Chain Reaction and Serologic Test Results in Children with SARS-CoV-2 Infection.

Objectives: To determine the time to reverse transcription-polymerase chain reaction (RT-PCR) negativity after the first positive RT-PCR test, factors associated with longer time to RT-PCR negativity, proportion of children seroconverting after proven severe acute respiratory syndrome coronavirus 2 infection, and factors associated with the lack of seroconversion.

Study Design: The Epidemiological Study of Coronavirus in Children of the Spanish Society of Pediatrics is a multicenter study conducted in Spanish children to assess the characteristics of coronavirus disease 2019. In a subset of patients, 3 serial RT-PCR tests on nasopharyngeal swab specimens were performed after the first RT-PCR test, and immunoglobulin G serology for severe acute respiratory syndrome coronavirus 2 antibodies was performed in the acute and follow-up (<14 and ≥14 days after diagnosis) phase.

Headache: pregnancy and breastfeeding. Recommendations of the Spanish Society of Neurology's Headache Study Group.

Introduction: Headache is one of the most common neurological complaints, and is most frequent during reproductive age. As a result, we are routinely faced with pregnant or breastfeeding women with this symptom in clinical practice. It is important to know which pharmacological choices are the safest, which should not be used, and when we should suspect secondary headache.

A Bayesian Model to Predict COVID-19 Severity in Children.

Background: We aimed to identify risk factors causing critical disease in hospitalized children with COVID-19 and to build a predictive model to anticipate the probability of need for critical care.

Methods: We conducted a multicenter, prospective study of children with SARS-CoV-2 infection in 52 Spanish hospitals. The primary outcome was the need for critical care.

Ventricular Repolarization Parameters and Coronary Involvement in Kawasaki Disease.

Objectives: To evaluate electrocardiogram markers to predict coronary involvement in patients with Kawasaki disease by assessing measures of ventricular repolarization parameters on the 12-lead electrocardiogram.

Study Design: This cross-sectional study included 180 Spanish and Japanese patients ≤14 years of age with Kawasaki disease, with or without coronary involvement, from 2011 to 2016. We manually measured the Tp-Te/QT ratio and QTc interval (with Bazett's formula) in 12-lead electrocardiogram in the acute and recovery period and explored their potential association with coronary involvement.

Pathogenic variants of DNAJC12 and evaluation of the encoded cochaperone as a genetic modifier of hyperphenylalaninemia.

Biallelic variants of the gene DNAJC12, which encodes a cochaperone, were recently described in patients with hyperphenylalaninemia (HPA). This paper reports the retrospective genetic analysis of a cohort of unsolved cases of HPA. Biallelic variants of DNAJC12 were identified in 20 patients (generally neurologically asymptomatic) previously diagnosed with phenylalanine hydroxylase (PAH) deficiency (phenylketonuria [PKU]).

[Epilepsias de origen metabólico en el neonato].

Neurometabolic diseases that manifest seizures and epilepsy are a large group of inherited disorders. They can present at any age from the neonatal period to adolescence. The epileptic manifestations can be very varied and, in general, they are epilepsies refractory to antiepileptic drugs.

[Early diagnosis of phenylketonuria. Physiopathology of the neuronal damage and therapeutic options].

Phenylketonuria, also known as PKU, is the most frequent congenital inborn error of metabolism. The severe form or classic PKU untreated causes intellectual disability, although with the early detection programs in the neonatal period, diagnosis and treatment prevent the appearance of the symptoms. Despite early diagnosis and treatment we have observed some neurotoxicity in treated PKU patients.

Headache: pregnancy and breastfeeding Recommendations of the Spanish Society of Neurology's Headache Study Group.

Introduction: Headache is one of the most common neurological complaints, and is most frequent during reproductive age. As a result, we are routinely faced with pregnant or breastfeeding women with this symptom in clinical practice. It is important to know which pharmacological choices are the safest, which should not be used, and when we should suspect secondary headache.

[Fetal alcohol spectrum disorder. An underdiagnosed neuro-development disorder of uncertain prognosis].

Prenatal exposure to alcohol is the cause of cognitive and behavioural disorders grouped under the term fetal alcohol spectrum disorders (FASD). The long-term evolution of subjects with FASD is often unfavourable, especially in social and academic fields. Executive dysfunction is a hallmark deficit for children with FASD with increased rates of externalizing behaviours, such as aggressiveness and frequently delinquency in adolescence and adulthood.

The changing epidemiology of invasive pneumococcal disease after PCV13 vaccination in a country with intermediate vaccination coverage.

Background: We studied the impact of 13-valent pneumococcal conjugate vaccine (PCV13) on the incidence of invasive pneumococcal disease (IPD) and serotype distribution in a region with intermediate levels of vaccination (around 64% in children aged <2 years).

Methods: Surveillance data on IPD cases reported by microbiologists participating in the Microbiological Reporting System of Catalonia during 2006-2014 were analysed. We compared estimated incidence rate (IR) ratios for serotypes included in PCV7, PCV10non7, PCV13non10 and non-PCV13 between the PCV7 (2006-2009) and PCV13 periods (2010-2014).

How and when to refer patients diagnosed with primary headache and craniofacial neuralgia in the Emergency department or Primary Care: Recommendations of the Spanish Society of Neurology's Headache Study Group.

Introduction: When a patient is diagnosed with primary headache or craniofacial neuralgia in the emergency department or in primary care, and is referred to a neurologist due to the complexity of the case, it is useful to know whether additional examination should be sought and the priority (urgent, preferential or normal) with which the patient should be seen. This will avoid unnecessary delays in patients with disabling headache and where organic causes are suspected. In order to issue recommendations on this matter, the Spanish Society of Neurology's Headache Study Group has decided to create a series of agreed recommendations constituting a referral protocol for patients with headache and/or craniofacial neuralgia.

[Hospital emergency room diagnosis of acute appendicitis in patients aged 2 to 20 years: the INFURG-SEMES score from the emergency infections study of the Spanish Society of Emergency Medicine].

Objectives: To develop the INFURG-SEMES scale (based on the emergency infections study of the Spanish Society of Emergency Medicine) using clinical and laboratory data to diagnose acute appendicitis (AA) in patients aged 2 to 20 years who were evaluated in hospital emergency departments and to compare its diagnostic yield to that of the Alvarado score.

Material And Methods: Prospective observational cohort study enrolling consecutive patients between the ages of 2 and 20 years who came to 4 hospital emergency departments with abdominal pain suggestive of AA and of less than 72 hours' duration. We collected demographic, clinical, analytic (white blood cell count, differential counts, and C-reactive protein [CRP] levels), and radiographic data (ultrasound and/or computed tomography scans).
