A randomized, observer-blind, vehicle-control, multi-center clinical investigation for assessing the efficacy and tolerability of a 1% ectoine and hyaluronic acid 0.1%-containing medical device in pediatric patients with mild-to-moderate atopic dermatitis.

BACKGROUND: Ectoine is a widespread osmolyte enabling halophilic bacteria to withstand high osmotic stress that has many potential applications ranging from cosmetics to its use as a therapeutic agent. OBJECTIVE: The aim of this study was to compare the efficacy and tolerability of ectoine 1% and hyaluronic acid 0.1% containing (EHA) cream with a vehicle cream in children with mild-to-moderate atopic dermatitis (AD). METHODS: A randomized, controlled, observer-blind, multicenter clinical trial was conducted in children aged 2-18 years, diagnosed with mild-to-moderate AD (SCORAD ≤20). Patients were randomized to either receiving EHA cream or vehicle cream twice daily for 4 weeks. The primary outcome measure was the mean change in objective SCORAD from baseline to the final visit. The secondary outcome measures included the mean change in Investigator's Global Assessment score, patient's judgment of efficacy and patient's assessment of pruritus. Safety of EHA cream was also assessed. RESULTS: A total of 70 patients (35 in each group) were randomized and 57 were included in the final analysis set. Based on SCORAD measurements, patients using EHA cream achieved superior clinical improvement compared to the control group at 28 days (p < .001). EHA cream was also superior to the vehicle cream regarding all secondary outcome measures. Eight (23.5%) patients receiving EHA cream and two (5.7%) patients receiving vehicle cream experienced mild cutaneous adverse events (AEs). CONCLUSIONS: In children 2-18 years old with mild-to-moderate AD, EHA cream was superior to vehicle cream, with minor AEs.

Development of a multidisciplinary clinic of neurofibromatosis type 1 and other neurocutaneous disorders in Greece. A 3-year experience.

Given the complexity of neurocutaneous syndromes, a multidisciplinary approach has been advocated in order to provide optimum care. Subjects and Methods: Retrospective analysis of a cohort of 157 patients during a 3-year period, seen at a newly developed neurocutaneous clinic in a pediatric tertiary care hospital in Athens (Greece); and systematic chart review of the patients diagnosed with neurofibromatosis type 1 during this time period. Results: The most frequent neurocutaneous syndromes were neurofibromatosis type 1 (NF1) in 89 patients and tuberous sclerosis complex in 17. In 20.38% of patients a neurocutaneous syndrome was not confirmed. Approximately 2/3 of the NF1 patients underwent genetic analysis, and for 76.67% of them, a pathogenic mutation on the NF1 gene was revealed. Eighty-one patients manifested with generalized NF1 and eight with mosaic NF1. Dermatological manifestations included café-au-lait macules in all patients, followed by axillary and/or inguinal freckling (n = 57), external plexiform neurofibromas (n = 17), and cutaneous and subcutaneous neurofibromas (n = 11). Approximately half of patients had learning disabilities and attention deficit hyperactivity disorder, followed by mental retardation (n = 9), autistic spectrum disorders (n = 4), headaches (n = 3) and seizures (n = 2). Neuroimaging showed characteristic areas of hyperintensity on T2-weighted images in 74.07% of patients and optic pathway glioma in 19.75%. Two patients developed malignant peripheral sheath nerve tumor. Conclusions: Neurocutaneous syndromes are clinically heterogeneous and the surveillance of potential clinical complications is challenging. The availability of genetic diagnosis and novel imaging methods in this group of disorders is likely to further expand their clinical spectrum. Guidelines for assessment and management will need to be modified based on new available data.
