Studysummary In this study, the researchers reported that calcipotriol pre-treatment made photodynamic therapy more effective and safe than conventional treatment for actinic keratosis on the scalp, improving long-term clearance rates, especially for Grade II lesions. However, they suggested larger trials are necessary to corroborate these findings. Our plain-language summary of this paper — not a Tressless recommendation.
A five-month-old boy presented with a three-month history of anogenital and distal skin lesions, alopecia, and diarrhea. He was exclusively breastfed, and there was no relevant family history. Physical examination showed erythematous erosive plaques with scaling and crusting on the anogenital area and distal extremities, along with diffuse scalp alopecia. The boy's plasma zinc level was found to be 6.3 μmol/L, indicating a deficiency, which was likely the underlying cause of his symptoms.
