Allergic Contact Dermatitis to Sculptured Nails

Sculptured artificial nails are a popular method of improving the cosmetic appearance of natural nails. They are made by mixing a liquid monomer with a powder polymer and then molding this acrylic compound onto the natural nail. We have recently seen a patient with allergic contact dermatitis to ethyl methacrylate, the liquid monomer used in these artificial fingernails. The purpose of this article is to report a case in which ethyl methacrylate was the sensitizer in the nail, and to demonstrate cross-sensitivity to methyl and N-butyl methacrylate. <h3>Report of a Case</h3> A 50-year-old woman used artificial fingernails for 1 1/2 years because of nail fragility. This process involved the mixing of ethyl methacrylate monomer with acrylic polymers. For several months prior to being seen in the clinic, a paronychial and eyelid dermatitis (Figure) occurred two days after each new application of the nails. Using the aluminum patch test technique, the

An Automatic Additive Color Printer

Solenoid-operated vane-type shutters in the printer control the red, green and blue beams split up from the white light by dichroic mirrors. The color light values and the fader-speed information are fed into the printer by a perforated tape, which also starts and stops the printer. Notches in, or aluminum patches on the film release the information prestored in a memory device to the light controls. Accessories and a sound printing head extend the flexibility of the printer.
