ABSTRACT
INTRODUCTION: Skin cancer prevention should ideally begin with healthy sun protection habits during childhood. Children's books can be effective tools to introduce healthy habits early in life and should be targeted toward all children regardless of skin tone. This study examined sun protection guidelines and the representation of skin tones in commercial children's books. METHODS: We performed internet searches for children's books about sun protection. We compared content from these books to current sun protection guidelines from the American Academy of Dermatology (AAD). We assessed books for reading level, author profession, and skin tone representation. RESULTS: Seventeen books met study criteria. Of 19 factors surrounding sun protection provided by the AAD, the median number of factors mentioned within children's books was nine (range 3-13). Of the 13 books with color illustrations of people, one (7.6%) book depicted people with dark skin tones on the cover, and three (23.1%) books depicted people with dark skin tones within the story. CONCLUSION: Commercial children's books about sun protection incorporate some, but not all, of the AAD guidelines, and there is an inadequate representation of darker skin tones within and on the cover of these books.

We report a child with a past medical history notable for congenital deafness, palmoplantar keratoderma (PPK), and hypothalamic glioma who initiated a MEK inhibitor trametinib for cancer-directed therapy at 11 years of age and was incidentally noted to have marked improvement in his PPK. Trametinib withdrawal led to worsening in the patient's PPK. We speculate that the patient's PPK improved because of trametinib, given the temporal relationship between trametinib therapy and PPK severity, observed both after introduction and withdrawal of trametinib therapy. The upregulation of MAPK signaling may be involved in the pathogenesis of keratinocyte proliferation in at least some forms of PPK, given that downstream inhibition of MAPK signaling led to an improvement in the patient's PPK.

Persons with Mild Cognitive Impairment (MCI) can experience deficits in working memory. In the present study, we investigated working memory in persons with MCI and cognitively healthy older adults using event-related potentials (ERPs). Participants performed an n-back working memory task with baseline (0-back), low load (1-back), and high load (2-back) working memory conditions. MCI participants' performance was less accurate than that of healthy older adults in both the 1-back and 2-back conditions, and reaction times were longer in MCI than control participants in the 0-back, 1-back and 2-back conditions. ERP analyses revealed delayed P200 and N200 latencies and smaller P300 amplitudes in MCI relative to control participants in the 0-back, 1-back and 2-back conditions. Deterioration in working memory performance concomitant with marked electrophysiological alterations suggests that persons with MCI exhibit deficits in several cognitive processes that include early attention, stimulus discrimination and classification, and updating and manipulation of information held in working memory.
