Asthma Control Test and Bronchial Challenge with Exercise in Pediatric Asthma.

Background: Poor asthma control can lead to exercise-induced bronchoconstriction (EIB), but the relationship between subjective disease control and EIB is unclear. No studies have compared asthma control test (ACT) scores of children with those of their parents regarding EIB. We assessed whether ACT scores predict the occurrence of EIB in two age groups.

Chronic granulomatous disease mimicking early-onset Crohn's disease with cutaneous manifestations.

Background: Chronic granulomatous disease is a rare inherited disorder of the innate immune system. In patients with a clinical history of recurrent or persistent infections, especially infections caused by uncommon species, chronic granulomatous disease should be considered.

Case Presentation: We report the case of a 5-year-old boy with a presumptive diagnosis of Crohn's disease with extraintestinal manifestations.

Tandem mass spectrometry, but not T-cell receptor excision circle analysis, identifies newborns with late-onset adenosine deaminase deficiency.

Background: Adenosine deaminase (ADA)-severe combined immunodeficiency (SCID) is caused by genetic variants that disrupt the function of ADA. In its early-onset form, it is rapidly fatal to infants. Delayed or late-onset ADA-SCID is characterized by insidious progressive immunodeficiency that leads to permanent organ damage or death.

Influence of cartilage and menisci on the sagittal slope of the tibial plateaus.

We analyzed the magnetic resonance studies of the knee in 80 subjects, 45 men and 35 women with a mean age of 38.9 years, who showed no pathological condition of the joint. Using an imaging visualization software, the sagittal longitudinal axis of the tibia was identified.

Molecular profiles of IgE to Phleum pratense in children with grass pollen allergy: implications for specific immunotherapy.

Background: The so-called component-resolved immunotherapy of allergies proposes an immunization tailored to the molecular sensitization profiles of individual patients.

Objectives: We sought (1) to investigate the profiles of IgE sensitization to Phleum pratense in children with grass pollen allergy and (2) to define the compatibility of these profiles with a mixture of recombinant allergenic molecules of P pratense previously proposed for specific immunotherapy.

Methods: We examined 200 children (age, 4-18 years; 126 boys) with allergic rhinitis, asthma, or both ascertained through validated questionnaires.
