Timing of itch among children with atopic dermatitis.
The purpose of this study was to test the hypothesis that pediatric patients experience greater nighttime itch in atopic dermatitis. The primary study outcome was time of worst itch by parent report. Parents were asked “Over the past 7 days, what time of day or night was your child’s itch the worst?” They were able to select the hour of worst itch, with separate questions for weekdays versus weekend. Parents also rated their child’s itch intensity (range, 0-10; 10 = worst) during the morning, afternoon, evening, bedtime, and sleep. Data on when the child tried to sleep and how long it took to fall asleep were used to calculate time of sleep onset. Similarly, children ages 8 to 17 years were independently asked to self-report on time of worst itch, itch intensity at different times of day, and time of sleep onset. The researchers analyzed 240 parent-child dyads, with parent-proxy reported data from 60 infants (1-4 years), 120 children (5-12 years), and 60 adolescents (13-17 years) with AD and child self-reported data from all the children aged 8 to 17 years (n = 133). Most often, parent-proxy reported worst itch occurred at 7:00 PM during weekdays and 8:00 PM during weekends. Parents of older children aged 8 to 17 years old also reported worst itch at 7:00 PM during weekdays and 8:00 PM during weekends. Time of worst itch was consistent across age groups but delayed slightly as children grew older, likely owing to later bedtime. Parents of infants reported worst itch most frequently at 6:00 PM and 7:00 PM, children at 7:00 PM, and adolescents at 7:00 PM, 8:00 PM, and 10:00 PM. The researchers conclude that itch intensity by time of day might be explained by differences in skin and inflammatory circadian rhythms in childhood AD. Alternatively, evening rituals such as bathing, use of hot water and soap, and changing clothes may trigger itch. It also may be that children have more activities during the day to distract them from itch.

Burden and characteristics of skin pain among children with atopic dermatitis.
The purpose of this study was to determine clinical features and quality-of-life (QOL) burden associated with atopic dermatitis (AD)- induced skin pain in children. The researchers conducted a national cross-sectional survey of child-parent dyads with AD. Questions were administered to the parent proxy for all participants, and children 8 years and older completed a similar questionnaire adapted for self-report. The researchers surveyed 240 children with AD and parent dyads, including 60 infants (1-4 years) and 180 children (5-17 years). This cohort included 200 (83%) with moderate to very severe disease. The study reported that 111 of 240 participants (46%) had parent-proxy reported skin pain, and 59 of 133 children (44%) aged 8 to 17 years had self-reported skin pain. Children self-reported slightly greater pain intensity than did their parents. Pain intensity was associated with clinical skin features of bleeding, weeping/ oozing, cracking, itch frequency, and itch severity. Quality of life scores were also analyzed, with results indicating that skin pain was a significant factor in lower quality of life scores. The researchers concluded that intensity of skin pain in children was associated with significant decreases in quality of life.

Parent report of sleep health and attention regulation in a cross-sectional study of infants and preschool-aged children with atopic dermatitis.
Older children with atopic dermatitis (AD) suffer from poor sleep and attention problems. However, until recently, the dearth of developmentally sensitive assessment tools impeded characterization in younger children. In this study the investigators aimed to characterize sleep and attention problems in young children with AD and identify modifiable factors. The investigators concluded that more severe AD correlates with poor sleep health and attention dysregulation.
