Congenital hydrocephalus: new Mendelian mutations and evidence for oligogenic inheritance.

Background: Congenital hydrocephalus is characterized by ventriculomegaly, defined as a dilatation of cerebral ventricles, and thought to be due to impaired cerebrospinal fluid (CSF) homeostasis. Primary congenital hydrocephalus is a subset of cases with prenatal onset and absence of another primary cause, e.g.

Nonmetastatic Rhabdomyosarcoma in Children and Adolescents: Overall Results of the European Pediatric Soft Tissue Sarcoma Study Group RMS2005 Study.

JCO The RMS2005 study included two phase III randomized trials for high-risk (HR) and observational trials for low (LR), standard (SR), and very high-risk (VHR) patients who have been partially reported. Herein, we present a comprehensive report of results achieved for the complete unselected nonmetastatic cohort and analyze the evolution of treatment in comparison with previous European protocols. After a median follow-up of 73.

Born into an isolating world: family-centred care for babies born to mothers with COVID-19.

Background: The benefits of facilitating breastmilk feeding and close contact between mother and neonate (family-centred care; FCC) in the perinatal period are well-established. The aim of this study was to determine how the delivery of FCC practices were impacted for neonates born to mothers with perinatal SARS-CoV-2 infection during the COVID-19 pandemic.

Methods: Neonates born to mothers with confirmed SARS-CoV-2 infection during pregnancy were identified from the 'EsPnIC Covid paEdiatric NeonaTal REgistry' (EPICENTRE) multinational cohort between 10 March 2020 and 20 October 2021.

[Crossed perspectives on pediatrics to adult health care transition in Belgium].

In Belgium, there is not yet a standardized procedure for supporting the transition of patients with chronic diseases from pediatrics to adult health care. However, the field increasingly calls for the development of multidisciplinary landmarks. By crossing perspectives of a pediatrician, two psychologists and an ethicist, we propose the key elements of a successful transition: 1.

Study Design: Prospective cohort study.

Setting: Tertiary referral medical center.

European standard clinical practice - Key issues for the medical care of individuals with familial leukemia.

Although hematologic malignancies (HM) are no longer considered exclusively sporadic, additional awareness of familial cases has yet to be created. Individuals carrying a (likely) pathogenic germline variant (e.g.

Lack of the human choline transporter-like protein SLC44A2 causes hearing impairment and a rare red blood phenotype.

Blood phenotypes are defined by the presence or absence of specific blood group antigens at the red blood cell (RBC) surface, due to genetic polymorphisms among individuals. The recent development of genomic and proteomic approaches enabled the characterization of several enigmatic antigens. The choline transporter-like protein CTL2 encoded by the SLC44A2 gene plays an important role in platelet aggregation and neutrophil activation.

Co-Occurrence of Hypohidrotic Ectodermal Dysplasia and Food Protein-Induced Enterocolitis Syndrome: A Report of a New Ectodysplasin A Variant.

Introduction: Ectodermal dysplasias (EDs) are a large group of rare and complex genetic disorders, affecting the development of two or more ectodermal structures. Hypohidrotic ED (HED) is the most frequent ED's phenotype and is characterized by hypodontia, hypotrichosis, and hypo/anhidrosis, leading to heat intolerance and hyperthermia.

Case Presentation: We report a case of a 2-year-old girl with hair and teeth abnormalities associated with severe digestive symptoms responsible for failure to thrive.

CTLA4, SH2B3, and CLEC16A diversely affect the progression of early islet autoimmunity in relatives of Type 1 diabetes patients.

The HLA region is the major genetic risk determinant of Type 1 diabetes. How non-HLA loci contribute to the genetic risk is incompletely understood, but there are indications that at least some impact progression of asymptomatic autoimmunity. We examined whether SNPs in 7 susceptibility loci (INS, SH2B3, PTPN2, PTPN22, CTLA4, CLEC16A, and IL2RA) could improve prediction of the progression from single to multiple autoantibody positivity, and from there on to diagnosis.

Toward reporting standards for the pathogenicity of variant combinations involved in multilocus/oligogenic diseases.

Although standards and guidelines for the interpretation of variants identified in genes that cause Mendelian disorders have been developed, this is not the case for more complex genetic models including variant combinations in multiple genes. During a large curation process conducted on 318 research articles presenting oligogenic variant combinations, we encountered several recurring issues concerning their proper reporting and pathogenicity assessment. These mainly concern the absence of strong evidence that refutes a monogenic model and the lack of a proper genetic and functional assessment of the joint effect of the involved variants.

Congenital hyperinsulinism-A case of mild hypoglycemia in an adult, detected by family testing.

Symptoms of mild hypoglycemia are easily overlooked especially when there are no complaints from the patients, but it could be a warning sign of an underlying genetic disease. Genetic testing for the entire family is a key step in neonatal hypoglycemia workup.

Clinical and molecular diagnosis of genodermatoses: Review and perspectives.

Genodermatoses are a complex and heterogeneous group of genetic skin disorders characterized by variable expression and clinical and genetic heterogeneity, rendering their diagnosis challenging. DNA-based techniques, like whole-exome sequencing, can establish a diagnosis in 50% of cases. RNA-sequencing is emerging as an attractive tool that can obtain information regarding gene expression while integrating functional genomic data with regard to the interpretation of variants.

Expectant Management or Early Ibuprofen for Patent Ductus Arteriosus.

Background: Cyclooxygenase inhibitors are commonly used in infants with patent ductus arteriosus (PDA), but the benefit of these drugs is uncertain.

Methods: In this multicenter, noninferiority trial, we randomly assigned infants with echocardiographically confirmed PDA (diameter, >1.5 mm, with left-to-right shunting) who were extremely preterm (<28 weeks' gestational age) to receive either expectant management or early ibuprofen treatment.

Primary Helicobacter pylori resistance to antimicrobials in the Brussels area in 2021.

This manuscript summarizes current primary resistance of Helicobacter pylori to antibiotics in Brussels in 2021. Resistance rates were estimated at 18% for clarithromycin, 24% for levofloxacin, 52% for metronidazole, and 0% for amoxicillin and tetracycline. When compared to 2016, resistance rates remain stable, except an increase of 30% for metronidazole.

Atypical procedural learning skills in children with Developmental Coordination Disorder.

We investigated the procedural learning deficit hypothesis in Developmental Coordination Disorder (DCD) while controlling for global performance such as slower reaction times (RTs) and variability. Procedural (sequence) learning was assessed in 31 children with DCD and 31 age-matched typically developing (TD) children through a serial reaction time task (SRTT). Sequential and random trial conditions were intermixed within five training epochs.

High Prevalence of Infection Among School-Aged Children in Ho Chi Minh City, VietNam.

There is no study on () infection in pupils of Ho Chi Minh city (HCMC), the most overcrowded city in Vietnam. Therefore, the aim of this study was to estimate the prevalence of and its geographical spread among school-aged children. A school-based cross-sectional study was conducted among 1854 pupils across 24 districts of HCMC in 2019.
