Impact of Allergic Rhinitis Control on Work Productivity and Costs: A Real-World Data MASK-air Study.

Background: Allergic rhinitis (AR) has a substantial socioeconomic impact associated with impaired work productivity.

Objective: To study the impact of AR on work productivity and estimate the corresponding indirect costs for 40 countries.

Methods: We conducted a cross-sectional study using direct patient data from the MASK-air app on users with self-reported AR.

Healthcare migration in Italian paediatric haematology-oncology centres belonging to AIEOP.

Background: In Italy, there is a network of centres headed by the Italian Association of Pediatric Hematology and Oncology (AIEOP) for the diagnosis and treatment of paediatric cancers on almost the entire national territory. Nevertheless, migration of patients in a hospital located in a region different from that of residence is a widespread habit, sometimes motivated by several reasons. The aim of this paper is to assess the impact of migration of children with cancer to AIEOP centres in order to verify their optimal distribution throughout the national territory.

Case Report: A child with NFKB1 haploinsufficiency explaining the linkage between immunodeficiency and short stature.

We report the case of a patient with common variable immunodeficiency (CVID) presenting with short stature and treated with recombinant human growth hormone (rhGH). Whole exome sequencing revealed a novel single-nucleotide duplication in the gene (c.904dup, p.

Childhood-onset Erdheim-Chester disease in the molecular era: clinical phenotypes and long-term outcomes of 21 patients.

Erdheim-Chester disease (ECD) is a rare histiocytic disorder that can present as a localized infiltration of foamy histiocytes or a multisystem disease that may be life-threatening. It is extremely rare in children. Pegoraro and colleagues present the clinical and molecular features of 21 patients with pediatric ECD through a large international collaboration, documenting that it resembles its adult counterpart, with similar molecular features and responses to agents targeting BRAF and MEK.

Surgical Atrioventricular Valve Replacement With Melody Valve in Infants and Children.

Background Pediatric patients with atrioventricular valve disease have limited options for prosthetic valve replacement in sizes <15 mm. Based on successful experience with the stented bovine jugular vein graft (Melody valve) in the right ventricular outflow tract, the prosthesis has been modified for surgical valve replacement in pediatric patients with atrioventricular dysfunction with the intention of subsequent valve expansion in the catheterization laboratory as the child grows. Methods and Results A multicenter, retrospective cohort study was performed among patients who underwent atrioventricular valve replacement with Melody valve at 17 participating sites from North America and Europe, including 68 patients with either mitral (n=59) or tricuspid (n=9) replacement at a median age of 8 months (range, 3 days to 13 years).
