Meatal stenosis, making it more difficult or even impossible to urinate, may also occur.On the non-genital skin, the disease may manifest as porcelain-white spots with small visible plugs inside the orifices of hair follicles or sweat glands on the surface. Thinning of the skin may also occur. Psychological effect
Distress due to the discomfort and pain of lichen sclerosus is normal, as are concerns with self-esteem and sex. Counseling can help.According to the National Vulvodynia Association, which also supports women with lichen sclerosus, vulvo-vaginal conditions can cause feelings of isolation, hopelessness, low self-image, and much more. Some women are unable to continue working or have sexual relations and may be limited in other physical activities. Depression, anxiety, and even anger are all normal responses to the ongoing pain LS patients experience. Pathophysiology
Although it is not clear what causes LS, several theories have been postulated. Lichen sclerosus is not contagious; it cannot be caught from another person.Several risk factors have been proposed, including autoimmune diseases, infections and genetic predisposition. There is evidence that LS can be associated with thyroid disease. Genetic
Lichen sclerosus may have a genetic component. A high correlation of lichen sclerosus has been reported between twins and between family members. Autoimmunity
Autoimmunity is a process in which the body fails to recognize itself and therefore attacks its own cells and tissue. Specific antibodies have been found in LS. Furthermore, there seems to be a higher prevalence of other autoimmune diseases such as diabetes mellitus type 1, vitiligo, alopecia areata, and thyroid disease.
Lipocortins can inhibit the common precursor of inflammation mediators, arachidonic acid. Interactions
Common medications causing a minor negative drug interaction include: Insulin and Metformin. Common medications checked in combination, but that are not known to create a negative drug interaction, include: Aspirin, Cymbalta (duloxetine), Fish Oil, Acetaminophen, Vitamin B12, Vitamin C, Vitamin D3, and Zyrtec. History
Desonide was first introduced in the United States under the trade name Tridesilon by Dome Laboratories in 1972. Since the discovery in the United States, several other countries have introduced different brand names of desonide, including Italy, Spain, United Kingdom, and Germany. The FDA first approved Connetics Corporation’s Verdeso Foam®
on September 16, 2006. Just shortly after, the FDA approved SkinMedica Inc.’s
Desonate® hydrogel delivery vehicle on October 20, 2006.Desonate® gel is currently manufactured by Bayer HealthCare
Pharmaceuticals Inc. in Whippany, NJ. DesOwen® creams, ointments, and lotions
are currently manufactured by DPT Laboratories, Ltd. in San Antonio Texas and
is marketed by Galderma Laboratories. Other suppliers for the generic desonide
include Rebel Distributors Corp and Perrigo New York Inc.

Research and clinical trials
Desonate was approved by the FDA following two major clinical trials in 2006. Each randomized, double-blind, placebo-controlled study enrolled 582 pediatric patients (between the ages of 3 months and 18 years). The patient was topically administered the drug or placebo two times a day for four weeks. Using the Investigator’s Global Severity Score (IGSS), the treatment was considered successful if at Week 4 there was at least a two (2) point decrease from the patient’s baseline IGSS.
