Tricoscopia en la alopecia areata / Trichoscopy in Alopecia Areata

La alopecia areata es una enfermedad autoinmune, que afecta al folículo piloso. Se presenta en forma de placas alopécicas e incluso pérdida de pelo corporal. El diagnóstico es clínico. Sin embargo, la tricoscopia, una técnica valiosa no invasiva, simple y rápida, mejora el diagnóstico, la monitorización del tratamiento y reduce la necesidad de procedimientos invasivos. Realizaremos una descripción de la utilidad de la tricoscopia en la alopecia areata. Los hallazgos tricoscópicos más frecuentes de la alopecia areata son los puntos amarillos, los puntos negros, pelos en signos de exclamación, pelos vellosos cortos, pelos acodados. Sin embargo, existen otros hallazgos menos frecuentes, pero útiles para realizar el diagnóstico. La buena respuesta al tratamiento implica la desaparición de los puntos negros, pelos rotos y pelos con signo de exclamación, pero la presencia de los puntos amarillos indica enfermedad crónica y mala respuesta (AU)

Alopecia areata is an autoimmune disease that affects the hair follicle and can present as bald patches on the scalp and hair loss in other parts of the body. Diagnosis is clinical but can be aided by trichoscopy, a simple, rapid technique that reduces the need for invasive procedures and can also help with monitoring treatment response. We review the usefulness of trichoscopy in alopecia areata. The most common trichoscopic findings are yellow dots, black dots, exclamation mark hairs, short vellus hairs, and coudability hairs. Other, less common, findings can also help establish a diagnosis. Good response to treatment is indicated by the disappearance of black dots, broken hairs, and exclamation mark hairs. The observation of yellow dots, by contrast, indicates chronic disease and poor response to treatment (AU)

Vitamina D para la práctica diaria / Vitamin D for daily practice

La vitamina D es una vitamina liposoluble cuya principal función en el organismo es la regulación del metabolismo calcio-fósforo. El receptor de la vitamina D está presente en la mayoría de las células nucleadas de nuestro organismo, por lo que se está descubriendo su intervención en múltiples procesos. Las 3 principales fuentes para su obtención son la radiación ultravioleta, la alimentación y la suplementación. La piel, a través de la radiación solar, proporciona el 90% de la vitamina D que necesitamos. En casos deficitarios se han de repasar los hábitos de exposición solar, alimentación y se ha de valorar la suplementación farmacológica. La medición en el organismo se realiza mediante la determinación de 25-hidroxicolecalciferol y valores por debajo de 20ng/ml se consideran inadecuados. En el momento actual no se recomienda el cribado universal de vitamina D, sino en aquellos casos en los que se sospeche un déficit

Vitamin D is a fat-soluble vitamin which has the regulation of calcium-phosphorus metabolism in the body as its main function. Vitamin D receptor is present in most of the nucleated cells of the body, and its role in multiple body processes is being discovered. The 3 main sources of vitamin D are ultraviolet sun radiation, diet, and supplementation. The skin, through solar radiation, provides 90% of the bodýs vitamin D needs. In cases of low vitamin D, sun exposure habits and diet must be reviewed, and pharmacological supplementation must be assessed. Measurement in the body is performed by determining 25-hydroxycholecalciferol with values below 20ng/ml being considered insufficient. Universal screening of vitamin D is not currently recommended, only in situations where a deficiency is suspected
