Dr. Dathan Hamann is a world-renowned expert in patch testing for the diagnosis of allergic contact dermatitis. Photopatch testing is the diagnostic test for light-activated allergic contact dermatitis.
The photopatch test is used to detect photoallergic reactions to various antigens that can be found in sunscreens, fragrances, or medicines. Various panels are applied to the patient’s back, and then they are exposed to UVA light.
After the exposure, panels are worn for two days, like standard patch testing, before Dr. Hamann would complete the reading and determine final results. Photo patch testing is the only way to make a definitive diagnosis of photoallergic eczema or photo allergic contact dermatitis.
The Wood’s Lamp is a small, hand-held device that illuminates areas of your skin with a black light to detect bacterial or fungal infections. It can also be used to help detect conditions such a vitiligo or even a corneal abrasion on the surface of the eye. The light is held over the skin in a dark room, and if certain bacteria, fungi, or skin pigment changes are present, the affected area will change color under the light.
An electrodessication unit is a multi-function electrosurgical device that can be used in a variety of dermatological procedures. It uses electricity to perform skin procedures. Because it can generate a wide range of power, it can be used for delicate cosmetic procedures or for controlling bleeding and limiting bruising during and after surgery. In some instances, it can also be used to treat early forms of skin cancer or precancers.
Cryotherapy uses liquid nitrogen to interact and change skin tissues. It is commonly used to destroy benign spots like warts or to treat precancerous spots. It can also be used on a cosmetic basis to remove skin tags, seborrheic keratoses, or to help lighten skin other benign spots. It can also be used to control itchy spots in some instances.
