Coexistence of junctional epidermolysis bullosa, autosomal recessive deafness type 57, and Angelman syndrome: A case report.

Key Clinical Message: The presence of more than one genetic/genomic disorder is not uncommon. It is therefore essential to continuously consider new signs and symptoms over time. Administration of gene therapy could be extremely difficult in particular situations.

Lower Respiratory Tract Infection and Genus Enterovirus in Children Requiring Intensive Care: Clinical Manifestations and Impact of Viral Co-Infections.

Infection by rhinovirus (RV) and enterovirus (EV) in children ranges from asymptomatic infection to severe lower respiratory tract infection (LRTI). This cohort study evaluates the clinical impact of RV/EV species, alone or in codetection with other viruses, in young children with severe LRTI. Seventy-one patients aged less than 5 years and admitted to the Paediatric Intensive Care Unit (PICU) of a reference children's hospital with RV or EV (RV/EV) LRTI were prospectively included from 1/2018 to 3/2020.

A study of paediatric patients with complex chronic conditions admitted to a paediatric department over a 12 month period.

Introduction: The number of patients with complex chronic conditions (CCC) has increased in the last 20 years or so. There is limited data as regards the prevalence of CCC in the paediatric population and its impact on hospital admissions. The main objectives of this study are to determine the proportion of CCC in the paediatric hospital population and compare them with other groups of patients admitted (acute and chronic).

Similarities and differences between the immunopathogenesis of COVID-19-related pediatric multisystem inflammatory syndrome and Kawasaki disease.

Multisystem inflammatory syndrome associated with the SARS-CoV-2 pandemic has recently been described in children (MIS-C), partially overlapping with Kawasaki disease (KD). We hypothesized that (a) MIS-C and prepandemic KD cytokine profiles may be unique and justify the clinical differences observed, and (b) SARS-CoV-2-specific immune complexes (ICs) may explain the immunopathology of MIS-C. Seventy-four children were included: 14 with MIS-C, 9 patients positive for SARS-CoV-2 by PCR without MIS-C (COVID), 14 with prepandemic KD, and 37 healthy controls (HCs).

Cholecystitis and nephrotic syndrome complicating Epstein-Barr virus primary infection.

Epstein-Barr virus (EBV) infection results in a spectrum of clinical manifestations. The host immune response to EBV plays a key role in the extent and degree of clinical features, which in children under 4 years of age are usually mild, non-specific and self-limiting. A 2-year-old boy in whom no known immune disorder could be found presented with acute acalculous cholecystitis, renal dysfunction with massive proteinuria, ascites, pleural effusion, minimal peripheral oedema and a severe systemic inflammatory response.

Efficacy and safety of TNF-alpha antagonists in children with juvenile idiopathic arthritis who started treatment under 4 years of age.

The aims of the study were to assess efficacy and safety of TNF-alpha antagonists (anti-TNF) in a cohort of patients with juvenile idiopathic arthritis (JIA) who began treatment under 4 years old and to assess relapse rate after methotrexate and/or anti-TNF withdrawal. We made a retrospective charts review of our non-systemic JIA patients treated with anti-TNF under 4 years of age between January 2006 and April 2013. Demographics, epidemiologic, clinical, laboratory data and rate of relapse after treatment withdrawal due to clinical remission were collected.

Frequency of apnea and respiratory viruses in infants with bronchiolitis.

The frequency of apnea in infants <12 months of age admitted with acute bronchiolitis was 5.16% (95% confidence interval: 3.94-6.

Non-systemic juvenile idiopathic arthritis outcome after reaching clinical remission with anti-TNF-α therapy: a clinical practice observational study of patients who discontinued treatment.

TNF-alpha-blocking agents (anti-TNF) used in juvenile idiopathic arthritis (JIA) are well established; however, time to withdraw is unclear. Neither prolonged nor tapering treatment seems to influence risk of relapse. Our aim was to assess relapse percentage after anti-TNF withdrawal of our non-systemic JIA patients after reaching clinical remission.

Analysis of human metapneumovirus and human bocavirus viral load.

Viral load (VL) of human metapneumovirus and human bocavirus in infants <12 months admitted for bronchiolitis was analyzed. VL correlated with length of hospital stay in both viruses, human metapneumovirus VL with the duration oxygen therapy and human bocavirus VL inversely with days of respiratory effort before admission. Infants coinfected by other viruses were younger, but no differences were seen regarding VL.

Clinical risk factors are more relevant than respiratory viruses in predicting bronchiolitis severity.

Background: The role of respiratory viruses in the pathogenesis of bronchiolitis was re-evaluated with the use of molecular methods such as PCR for virus detection. Whether specific viruses or the classical clinical risk factors are more important in determining severe bronchiolitis is not well established.

Aim: To analyze the specific viruses and clinical variables that can predict severe bronchiolitis at admission.

Prevalence of human metapneumovirus among hospitalized children younger than 1 year in Catalonia, Spain.

Human metapneumovirus was discovered recently respiratory virus implicated in both upper and lower respiratory tract infection. In children, the clinical symptoms of human metapneumovirus are similar to those produced by respiratory syncytial virus, ranging from mild to severe diseases such as bronchiolitis and pneumonia. The aim of the present study was to describe the prevalence of human metapneumovirus and other common respiratory viruses among admitted to hospital infants.
