Demonstration of spread-on peel-off consumer products for sampling surfaces contaminated with pesticides and chemical warfare agent signatures.

A terrorist attack using toxic chemicals is an international concern. The utility of rubber cement and latex body paint as spray-on/spread-on peel-off collection media for signatures attributable to pesticides and chemical warfare agents from interior building and public transportation surfaces two weeks post-deposition is demonstrated. The efficacy of these media to sample escalator handrail, stainless steel, vinyl upholstery fabric, and wood flooring is demonstrated for two pesticides and eight chemicals related to chemical warfare agents.

Angiolymphoid hyperplasia successfully treated with an ultralong pulsed dye laser.

Background: Angiolymphoid hyperplasia with eosinophilia (ALHE) is a benign vascular proliferation characterized by dermal or subcutaneous nodules or both, primarily in the head and neck. We report the successful treatment of ALHE without scarring using a 595 nm ultralong pulsed dye laser, which applies a unique combination of longer wavelengths, a longer pulse duration, and a higher fluence.

Objective: To report the use of the 595 nm pulsed dye laser in the treatment of ALHE and to detail the particular aspects of this laser that make it uniquely qualified to treat this entity.

Pilonidal sinus disease treated by depilation using an 800 nm diode laser and review of the literature.

Background: Pilonidal sinus disease is a debilitating, disfiguring chronic ailment that is often resistant to therapy. Its etiology and treatment remain in question.

Objective: To assess the efficacy of an 800 nm diode laser in the treatment of recalcitrant pilonidal sinus disease.

Injecting 1000 centistoke liquid silicone with ease and precision.

Background: Since the Food and Drug Administration approved the use of the 1000 centistoke liquid silicone, Silikon 1000, for intraocular injection, the off-label use of this injectable silicone oil as a permanent soft-tissue filler for facial rejuvenation has increased in the United States. Injecting liquid silicone by the microdroplet technique is the most important preventive measure that one can use to avoid the adverse sequelae of silicone migration and granuloma formation, especially when injecting silicone to improve small facial defects resulting from acne scars, surgical procedures, or photoaging.

Objective: To introduce an easy method for injecting a viscous silicone oil by the microdroplet technique, using an inexpensive syringe and needle that currently is available from distributors of medical supplies in the United States.

Celecoxib, a cyclooxygenase 2 inhibitor as a potential chemopreventive to UV-induced skin cancer: a study in the hairless mouse model.

Objective: To assess the preventive effect of a cyclooxygenase 2 inhibitor, celecoxib (Celebrex; G.D. Searle & Co, Skokie, Ill), in UV-induced skin cancer in hairless mice.

Unilateral colloid milium of the arm.

We describe a case of colloid milium limited to the left arm. To the best of our knowledge, only 2 other cases of unilateral colloid milium have been reported. All of these patients had occupational UV light exposure patterns that could account for this unique distribution.
