Participation Criteria
Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Genders Eligible for Study
Description
Inclusion Criteria:
- Patient must have a hypertrophic burn scar treated by skin grafts or allowed to heal secondarily
- Burn must have occurred within the last 2 years from time of recruitment
- Patient must have symptoms of pain and/or itch and/or hypersensitivity in the hypertrophic burn scar area
- Patient must already be planning to undergo laser treatment for their burn scar
- Patient must be willing to undergo biopsy procedures
- Patient must be willing and able to participate in the study with a year of follow-up
- Not be pregnant or planning to become pregnant during the treatment phase of the study
Exclusion Criteria:
- Medical Conditions that preclude laser treatment
- Active tanning, including the use of tanning booths, during the course of the study
- Inability to complete surveys
- Previous laser (PDL, CO2), surgical reconstructive treatment procedures done on the hypertrophic burn scar
- Current treatment with other procedures or drugs (experimental or other) in area of interest
- Medications that interfere with wound healing (oral steroids, immunosuppressive medications, chemotherapy or other)
- Medication for itch (steroids, antihistamines, or other)
- Medication for pain (opioids, topical pain treatment, gabapentin, ondasetron, paroxetine or other)
- Adverse reactions to topical or local anesthetic agents needed for this study, if no alternative to the said agent exists
- The study area should not be part of a contracture or other hypertrophic scar that would be better treated with surgical procedures.
- The study scar must not be adjacent to/in continuity with areas of HTBS that are planning to be treated with surgical interventions.
- Any other condition or laboratory value that would, in the professional opinion of the investigator, potentially affect the subject's response or the integrity of the data or would pose an unacceptable risk to the subject
- Patient suffers from epilepsy or seizure disorder.

Other: Treatment
Laser treatment to 3x3cm2 area.
It will receive the Luminous ultra pulse fractional ablative carbon dioxide laser at 150mJ, 3% density and 250Hz

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Histological change in nerve density
Time Frame: 7 months
|
The investigators will stain the collected skin with markers specific to nerves to in order to count the number of nerves per biopsy area.
|
7 months
|
Histological change in nerve morphology
Time Frame: 7 months
|
The investigators will stain the collected skin with markers specific to nerves to in order to compare the size and shape of cutaneous nerves before and after treatment.
This will be based on subjective evaluation and not a predetermined scale.
|
7 months

Secondary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Symptomatic Improvement Assessment
Time Frame: 7 months
|
Patient Reported Outcome Measures will be collected via the Patient and Observer Scar Assessment Scale (POSAS). This is a validated questionnaire that includes 5 physician-completed parameters and 6 patient-reported measures. Each parameter is rated from 1-10 with a score of 1 representing "skin that appears close to normal" and 10 representing the "worst scare imaginable". Overall, the final score will range from 11( best outcome) to 110 (worst outcome). Physician parameters relate to the scar appearance such as color and thickness of the scar; while the patient-reported parameters also include symptomatic factors, such as degree of pain associated with the scar |
