Introduction: Onychomycosis infections are diffi cult and time consuming conditions to treat. Recent advances in laser technology have proposed the use of ND YAG therapy as an alternative to topical treatments.

Method: A total of 20 individual Nails with clinical Onychomycosis were treated with ND YAG. Treatment consisted of raising the nail plate temperature to forty degrees Celsius. Nail bed temperatures were monitored using an electronic temperature device. The fl uence was adjusted for patient comfort. 60 mj/cm 2 – 270 mj/cm 2 . Time taken to achieve specifi ed temperatures varied from thirty seconds to one minute. Photographic records where kept for monitoring and effi cacy purposes.

Results: Efficacy was determined by assessing reduction in total volume of affected nail. All patients achieved a clinical response within the fi rst two months after treatment. In patients who regressed two months after ND YAG, a second treatment was offered with good clinical improvement. A summary of current literature will be presented along with the case series. with topical therapy and several courses of UV light. She eventually developed hand dermatitis related to her work, and was referred by her treating dermatologist to a colleague for a second opinion and then referred for patch testing. She developed positive patch tests to a number of relevant allergens. Allergic contact dermatitis to p-phenylenediamine in hair dye explained some of her rashes, particularly involving her posterior neck, upper chest and back over the years. She reacted to coconut diethanolamide which was present in her Microshield cleansers, explaining her occupational hand dermatitis, and also reacted to citral and fragrances. It took time for her skin to improve, but eventually she was rash-free and happy. The concept of polysensitisation is gaining some traction in the literature: that is, some patients are likely to have multiple contact allergies.
