Lichen striatus (LS) is a benign, self-limited, linear, inflammatory dermatosis of unknown etiology that usually affects children. We analyzed 89 cases in regard to age of appearance, sex, race, symptoms, seasonal incidence, localization of lesions and affected side of the body, and presence of atopy. Lesions predominated on the inferior limbs, with no preponderance of any age, and were asymptomatic in the majority of the instances. There was no difference in the incidence of LS in regard to the season of the year. A possible association of lichen sclerosus with atopy and pruritus was observed.

Levels of 25-hydroxyvitamin D were deficient or insufficient in 85% of the children, but serum vitamin D concentrations were not significantly related to AD severity.

Background Educational intervention (EI) could improve understanding of atopic dermatitis (AD) and adherence to treatment, decreasing severity, and improving quality of life (QoL). Objective This study aims to evaluate the influence of an EI on the severity of the disease and on the QoL in children with AD. Methods A controlled clinical trial was performed, including children up to 14 years of age with AD. Patients were allocated into control group (CG), which received usual guidelines on AD during the outpatient visit, and a study group (SG) that, in addition to the usual guidelines, participated in the EI. The severity of AD was assessed by Scoring Atopic Dermatitis (SCORAD) and Eczema Area and Severity Index (EASI). QoL was assessed by the Children's Dermatology Life Quality Index and the Dermatitis Family Impact Questionnaire. Results Twenty-seven participants were included in the CG and 21 in the SG. There was a decrease in the median value for the QoL of children in the SG after the intervention ( p = 0.04), as well as in the caregiver's ( p = 0.04). In the CG, the median QoL of children and caregivers remained unaltered, for caregivers the median value for the QoL was equal throughout first and second evaluation ( p = 0.32). In the SG, EASI values decreased after the intervention ( p = 0.04), as well as SCORAD ( p = 0.04). The CG did not show any decrease in the values of EASI ( p = 0.88) scores nor of SCORAD scores ( p = 0.82). Conclusion The EI rendered a decrease in severity of the disease and improvement in the QoL of patients and their caregivers.
