Transferencia de níquel mediante los dedos / Nickel Transfer by Fingers

Ante los casos de pacientes con historia de dermatitis facial y con dermatitis de contacto por hipersensibilidad al níquel se propuso investigar fuentes alternativas de exposición, por ejemplo monedas, que fuesen transferidas por los dedos hasta la región facial. Se utilizó cinta adhesiva común para realizar un stripping sobre los dedos y los pómulos de los voluntarios, y se llevó a cabo un análisis a través de técnicas de espectrometría atómica. Los resultados de níquel obtenidos fueron positivos tanto en los dedos, 14,67 ppm a 58,64 ppm, como en los pómulos, desde 1,28 ppm a 8,52 ppm, con niveles en controles muy inferiores y significativamente distintos a dichos valores. La transferencia de níquel desde el objeto que lo contiene hasta la cara del individuo mediante sus dedos podría justificar la clínica presentada por estos pacientes (AU)

We investigated fingers as a potential source of nickel transfer to the face in patients with allergic contact dermatitis to nickel and a history of facial dermatitis. Samples were collected from the fingers and cheeks of volunteers using the stripping method with standard adhesive tape, and nickel levels were quantified using mass spectrometry. Fingers and cheeks of individuals who had handled coins were both positive for nickel, with levels ranging from 14.67 to 58.64 ppm and 1.28 to 8.52 ppm, respectively. The levels in a control group were considerably and significantly lower. Transfer of nickel from a person’s fingers to their face after handling a nickel-containing object could explain the presence of facial dermatitis in patients with nickel hypersensitivity (AU)

Nickel transfer by fingers.

We investigated fingers as a potential source of nickel transfer to the face in patients with allergic contact dermatitis to nickel and a history of facial dermatitis. Samples were collected from the fingers and cheeks of volunteers using the stripping method with standard adhesive tape, and nickel levels were quantified using mass spectrometry. Fingers and cheeks of individuals who had handled coins were both positive for nickel, with levels ranging from 14.67 to 58.64 ppm and 1.28 to 8.52 ppm, respectively. The levels in a control group were considerably and significantly lower. Transfer of nickel from a person's fingers to their face after handling a nickel-containing object could explain the presence of facial dermatitis in patients with nickel hypersensitivity.
