Whatís New in Wound Healing

Chronic wounds are painful, increase the risk of infection, and can be socially debilitating. Common locations are leg ulcers, most commonly due to venous (blood vessel) deterioration from obesity, lack of physical activity, smoking, work that requires long periods of standing, past deep venous clots, and past infection. Another common location is the buttock, which is a frequent location for pressure sores.

There has been increased interest in using topical solutions, specifically a beta blocker called timolol to improve wound healing. Specifically, Dr. Kirsner, a wound care expert, has published several cases where applying roughly 1 drop every 2 cm along the wound edge dramatically reduced the wound size. The average improvement was 78.2% after 7 weeks of treatment. While this was not complete resolution nor was it quick, it was a clear improvement. Prior studies have showed that beta blockers block catecholamines which may play a role in chronic wounds.

This is of course in addition to the many other treatments needed to improve healing including keeping the area clean, reducing swelling, treating any infection that may be present, stopping any smoking, losing weight if needed, and treating any diabetes or high blood pressure that exists. Note that a general dermatology office does not have all the tools necessary for curing the most severe chronic wounds such as skin grafts (either from the patient or human skin cultures) and advanced dressing materials (foams, hydrocolloids, hydrogels). Another caveat is that, in my experience, insurance almost never covers home wound care supplies which can be quite expensive. Even the timolol solution may not be covered. Last, for wounds that your primary care doctor thinks is not doing well, a wound care center may be appropriate for many patients, especially the most severe.

For most wounds, primary care is the first appointment to make. However, if your wound needs additional evaluation, I look forward to seeing you. Please make an appointment for a dermatology consultation at (626) 331-6411.
