This study adds to the small existing literature demonstrating the validity of actigraphy in middle childhood. Although actigraphy shows good sensitivity (ability to detect sleep), specificity (ability to detect wake) is poor in this age group. Further, the results highlight the importance of considering whether a child has PLMS when interpreting actigraphic data, as well as the difficulties in accurately capturing sleep onset latency with actigraphy.

Severe pediatric pneumonia accounts for a significant number of PICU admissions and is associated with significant mortality risk. The presence of co-morbidities, HAP and bacteremia were early prognostic variables independently associated with poor clinical outcomes.

AR is more common in male children, is relatively rare below the age of 2 years, and accounts for two-thirds of all childhood chronic rhinitis and 73.3% of all chronic rhinitis in school-aged children (≥6 years old). Children with AR have more severe rhinitis symptoms and more often suffer from asthma-related events and admissions.

A substantial proportion of children with asthma have persistent BHR despite good clinical control. The concordance between clinical assessment of asthma control, BHR and FeNO was observed to be poor. Our findings raise concerns in the context of emerging evidence for the role of bronchoconstriction in inducing epithelial stress that may drive airway remodeling in asthma.
