Eruptive Melanocytic Nevi in the Setting of Encorafenib, Cetuximab, and Binimetinib Combination Therapy: A Case Report.

Introduction: The development of new and changing melanocytic lesions has been increasingly reported as an adverse dermatologic toxicity of BRAF inhibitor therapy. Melanocytic lesions and melanomas induced by BRAF inhibitor therapy that lack V600E expression have been less commonly described. One mechanism that has been proposed for the development of BRAF inhibitor-induced melanocytic lesions, including those lacking V600E expression, is the paradoxical activation of the MAPK signaling pathway in wild-type () cells.

The effect of a preparation containing glycocholic acid on the biocidal efficacy of sodium hypochlorite in a biofilm laboratory model.

This study assessed the antimicrobial effect of sodium hypochlorite (NaOCl) mixtures combined with Keratobacter (KB) using an engineered biofilm root canal model. Clinical and reagent grade NaOCl were mixed with KB (9:1-vol/vol) to assess pH values over 1 min to select the ideal solution with a pH just below the pKa of hypochlorous acid. The samples were randomly divided into five groups: 1% and 4% NaOCl reagents, a mixture of NaOCl:KB using 1% and 4% NaOCl reagents and distilled water.

Home stimulation, development, and nutritional status of children under 2 years of age in the highlands of Madagascar.

Background: The Vakinankaratra region of Madagascar has a high burden of child undernutrition which, in addition to poor psychosocial stimulation, is a strong risk factor of poor child development. However, there are limited studies evaluating the relations between developmental deficits, child nutrition outcomes, and home stimulation in the region. The purpose of this study was to assess the development of children aged 11-13 months in relation to their nutritional status and to examine parental home stimulation attitudes and practices in the Vakinankaratra region.
