Background:
Phototherapy is a useful therapy for many dermatologic disorders and is known for its low side-effect profile. However, one potential notable side effect is genital skin cancer. Unfortunately, no standards for genital protection currently exist for this preventable complication. Patients treated with phototherapy may already have a decreased quality of life because of their primary dermatologic disorder. Development of squamous cell carcinoma of the genitalia may certainly further affect the quality of life.
Objective:
The objective was to determine which readily available materials afford the best photoprotection of the male genitalia.
Methods:
Seven common materials used in phototherapy units for genital protection were placed over ultraviolet (UV) B and UVA monitors and placed in broadband UVB, narrowband UVB, and UVA full-body units. The percentage of light blocked was then calculated.
Results:
Blue and white cotton underwear, blue surgical towels, an athletic supporter with or without a cup, and the psoralen plus UVA pouch provided acceptable means of genital protection; however, surgical masks did not.
Limitations:
Only the most commonly used materials were tested in the phototherapy units. The materials were not of a single material type or similar masses. In addition, only one of each type of full-body phototherapy unit was used to obtain the data.
Conclusion:
Although a polyester composition provides better UV protection, factors such as low porosity and higher mass are intrinsic to decreasing the amount of UV penetration of any fabric. Of the commonly used objects, surgical masks do not provide sufficient protection to the genital area.

Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
