Specific Morphology of Coronary Artery Aneurysms in Mainly White Patients With Kawasaki Disease: Initial Data From the Cardiac Catheterization in Kawasaki Disease Registry.

Background: Patients with Kawasaki disease (KD) with coronary artery involvement require long-term cardiac care. Although respective evidence-based recommendations are missing, cardiac catheterization is still considered the gold standard for diagnosing detailed coronary pathology. Therefore, to better understand coronary artery pathology development, we conducted a survey to document and evaluate cardiac catheterization data in a European population.

Early relapse prediction after allogeneic hematopoietic stem cell transplantation for acute lymphoblastic leukemia (ALL) using lineage-specific chimerism analysis.

Relapse is a major cause of treatment failure after hematopoietic stem cell transplantation (HSCT) for acute leukemia. Here, we report a monocentric retrospective study of all HSCTs for B cell acute lymphoblastic leukemia (ALL) performed during the years 2005-2021 ( = 138, including 51 children), aiming to identify the optimal use of lineage-specific recipient-donor chimerism analysis for prediction of relapse. In adults, relapse was associated with increased recipient chimerism in CD3 bone marrow cells sampled at least 30 days before a relapse.

Establishment of resilience in a challenging recovery at home after pediatric tonsil surgery-Children's and caregivers' perspectives.

The objective of this study was to explore children's and caregivers' experiences and management of postoperative recovery at home after tonsil surgery. The study had an explorative qualitative design with an inductive approach. Twenty children (5-12 years of age) undergoing tonsillectomy or tonsillotomy with or without adenoidectomy participated along with their caregivers in semi-structured interviews at a mean time of 28 days after surgery.

The association between polygenic scores for attention-deficit/hyperactivity disorder and school performance: The role of attention-deficit/hyperactivity disorder symptoms, polygenic scores for educational attainment, and shared familial factors.

Background: Polygenic scores (PGS) for attention-deficit/hyperactivity disorder (ADHD) negatively predicts educational attainment (EA), but it remains unclear how ADHD symptoms, PGS for EA, and shared familiar factors influence the associations between PGS for ADHD and school performance.

Method: We combined survey data on ADHD symptoms, PGS, and register-based, objective measures of compulsory school performance at age 16 for 6049 twins in the Child and Adolescent Twin Study in Sweden. Linear and instrumental variable (IV) regression models were used to estimate the association between PGS for ADHD and grade point average (GPA), overall and by natural science, humanities, and practically oriented (e.

The erroneous perception of a clinical sign: Cholestasis preceding sepsis mimicking hepatitis in an adolescent patient.

Jaundice should be considered as a first clinical sign preceding severe invasive bacterial infection or sepsis in patients of all ages including childhood and adolescence. Early laboratory investigations and MR imaging studies for osteomyelitis or myositis are paramount to avoid progression to life-threatening sepsis and significant morbidity and mortality.

Population-based cohort study on the epidemiology of acute appendicitis in children in Sweden in 1987-2013.

Background: The long-term incidence of acute appendicitis has been reported to be declining in Europe and North America. Recent reports, however, indicate stabilized or even increased rates. The aim of this study was to investigate the present epidemiology of acute appendicitis and appendicectomy in a population-based cohort of Swedish children.
