Medical Procedures

Dr. Brune performs many dermatology medical procedures to treat a variety of skin conditions. These procedures are safely performed in-office for children and adults

Liquid Nitrogen or "Freezing"

Cryosurgery uses liquid nitrogen, a cold liquefied gas with a temperature of 196 degrees below zero Celsius (-321 degrees Fahrenheit). It is used to freeze and destroy superficial skin growths such as warts and keratoses. Liquid nitrogen causes stinging and mild pain while the growth is being frozen and then thaws. This discomfort usually lasts for less than five minutes.

After a liquid nitrogen treatment, the treated skin becomes swollen and red, and may blister. A scab or crust forms, which falls off by itself in one to three weeks. The skin growth will also come off with the scab, leaving healthy new skin.

Phototherapy (Narrow-Band UVB)

Ultraviolet Light B (UVB) is an effective treatment for psoriasis, as well as eczema, vitiligo and other conditions of the skin. It is found in natural sunlight. There are two types of UVB light, broadband and narrowband. Our office utilizes narrow-band UVB, which is a more specific type of light. Studies indicate that narrow-band UVB can clear psoriasis faster and produces longer remissions than broadband UVB.

Treatments are administered in our office. Usually, the patient undresses to expose all affected areas to the ultraviolet light. He or she then stands in a treatment booth lined with UVB lamps and the medical assistant administers the light treatment. A person will generally receive treatments three times per week and has regular follow up visits with the doctor. UVB treatment is used in conjunction with topical medications prescribed by the doctor.


While phototherapy can significantly improve a patient's skin and even completely clear certain conditions in some cases, phototherapy does carry these risks:

Dermatologists Carefully Weigh Risks and Benefits

Phototherapy is not appropriate for every patient. Dermatologists have the medical training and experience needed to carefully weigh the risks and benefits of phototherapy to determine if this treatment is right for a patient. In considering whether or not phototherapy is appropriate, dermatologists look at a number of factors, including the patient's age, health, medical history, severity of the condition, and history of previous treatment.

Photodynamic Therapy or "Blue light"

Levulan Kerastick (aminolevulinic acid HCl) for Topical Solution, 20% (Levulan Kerastick) plus blue light illumination using the BLU-U Blue Light Photodynamic Therapy Illuminator (Levulan PDT) is indicated for the treatment of minimally to moderately thick precancerous spots called actinic keratosis. Actinic keratoses (AKs) are rough-textured, dry, scaly patches on the skin that can lead to skin cancer. Levulan PDT, a 2-part treatment, is unique because it uses a light activated drug therapy to destroy AKs.

Patch Testing

Patch testing is a simple procedure to help diagnose what things are causing allergic reactions in your skin, such as contact dermatitis. T.R.U.E. TEST is a convenient, ready-to-use patch test for the diagnosis of allergic contact dermatitis. Based on the kind of rash you have, the doctor will decide if testing is appropriate for you.
