Key clinical point: Industry-provided materials failed to capture the range of procedural pain scores reported by patients undergoing a variety of vascular laser procedures.

Major finding: The average procedural pain scores for treatment types reported by subjects were translated to entirely different verbal and numerical categories of pain from those described by industry materials.

Study details: A retrospective evaluation of 85 procedural pain scores collected from 22 subject charts.

Disclosures: Dr. Bonati reported having no financial disclosures.

Key clinical point: A device that delivers high magnetic energy was found safe and effective for treatment of skin laxity.

Major finding: Following treatment, dermatologists graded nearly half of the patients (48%) at 50% or greater improvement.

Study details: A single-center trial of 20 patients with facial and upper skin laxity who underwent a mean of 4.3 treatment sessions.

Disclosures: Rocky Mountain Biosystems and BioFusionary Corp. provided the device used for the study. Dr. Garden reported having no financial disclosures.

At what diameter does a scar form after a full-thickness wound?

Article Type

Fri, 03/29/2019 - 17:44

 

– A clinically identifiable scar occurs after full-thickness skin wounds greater than 400-500 mcm in diameter, while wounds of smaller diameter heal with no clinically perceptible scar.

Dr. Amanda H. Champlain

The findings come from a small pilot trial that set out to determine the biopsy size limit at which healing occurs without a scar, as well as demonstrate the safety of performing multiple skin microbiopsies. “The broader purpose of this work is to contribute to the development of techniques for harvesting skin tissue with less morbidity than conventional methods,” lead study author Amanda H. Champlain, MD, said in an interview in advance of the annual conference of the American Society for Laser Medicine and Surgery. “The size threshold at which a full-thickness skin wound can heal without scarring had not been determined prior to this study.”

Dr. Champlain, a fellow at Massachusetts General Hospital and The Wellman Center for Photomedicine, both in Boston, and her colleagues designed a way to evaluate healing responses and safety after collecting skin microbiopsies of different sizes from preabdominoplasty skin. According to the study abstract, the concept “is based on fractional photothermolysis in which a multitude of small, full-thickness thermal burns are produced by a laser on the skin with rapid healing and no scarring.” Measures included the Patient and Observer Scar Assessment Scale (POSAS), donor site pain scale, subject satisfaction survey, and an assessment of side effects, clinical photographs, and histology.

Preliminary data are available for five subjects. The POSAS-Observer scale ranges from 5 to 50 while the POSAS-Patient scale ranges from 6 to 60. The researchers observed that average final POSAS-Observer scores were 5.6 for scars 200 mcm in diameter, 5.2 for scars 400 mcm in diameter, 7.0 for scars 500 mcm in diameter, 6.8 for scars 600 mcm in diameter, 8.2 for scars 800 mcm in diameter, 9.6 for scars 1 mm in diameter, and 13.2 for those 2 mm in diameter. Meanwhile, the average final POSAS-Subject scores were 6.0 for scars 200 mcm in diameter, 6.0 for scars 400 mcm in diameter, 6.6 for scars 500 mcm in diameter, 6.4 for those 600 mcm in diameter, 7.2 for scars 800 mcm in diameter, 7.4 for scars 1 mm in diameter, and 10.0 for those 2 mm in diameter.

The maximum donor site pain reported was 4 out of 10 in one subject. “The procedure was very well tolerated by the subjects,” Dr. Champlain said. “They healed quickly, and the majority were happy with the cosmetic outcome regardless of the diameter of the microbiopsy used.”

The most common side effects of the study procedures included mild bleeding, scabbing, redness, and hyper/hypopigmentation. “The majority of study participants strongly agree that the study procedure was safe, tolerable, and cosmetically sound,” she said.

Dr. Champlain does not have any disclosures, but she said that the study was funded by the Department of Defense.

More than 1 in 10 dermatology residents report laser-associated adverse events in training

Laser-associated adverse events are not uncommon – affecting more than 1 in 10 dermatology residents, results from a novel survey demonstrated.

“Incorporating a formal laser safety education curriculum is an opportunity for residency programs and organizations like ASLMS,” study coauthor Daniel J. Bergman, MD, said in an interview in advance of the annual conference of the American Society for Laser Medicine and Surgery.

In what is believed to be the first study of its kind, Dr. Bergman and his coauthor Shari A. Ochoa, MD, created an online survey intended to evaluate the safety education and number of adverse laser-associated events that occurred during dermatology residencies in the United States. After the coauthors sought input for content of the survey from dermatology faculty and their colleagues at the Mayo Clinic in Scottsdale, Ariz., they used the Association of Professors of Dermatology email database to distribute the survey to Accreditation Council for Graduate Medical Education (ACGME)–approved dermatology residency programs. “In general, most studies evaluate the models of education and the number of hours dedicated to learning a skill,” said Dr. Bergman, who is a first-year dermatology resident at the Mayo Clinic. “This study is unique because it identified adverse events experienced by dermatology residents and also evaluated their formal laser safety training.”


To date, 78 dermatology residents have completed responses to the survey. Of these, 10 (13%) identified an adverse event associated with use of a laser. Of those respondents, six respondents knew how to report the event, five felt comfortable operating the laser, three had formal laser safety training, five felt like they understood the risks associated with lasers, and all but one felt properly supervised. One identified plans for postresidency laser training. Of the 68 respondents who have not identified an adverse event, 39 (57%) reported formal laser safety training, and only 24 (35%) indicated that they knew how to report an adverse event.

“I was interested to find that 13% of dermatology residents have already experienced an adverse laser event,” Dr. Bergman said. “I was also surprised to discover that only 54% of all survey respondents identified or recognized formal laser safety training. The ACGME mandates that dermatology residents receive training in the theoretical and practical applications of lasers. This finding may indicate that additional training, focusing on laser safety, should be incorporated more formally into the curriculum at some programs.”

He acknowledged certain limitations of the study, including the relatively small number of respondents and the fact that only ACGME-accredited residencies were asked to participate. “Therefore, we are still missing a large amount of data,” Dr. Bergman said. “Most notably, the results are subject to recall bias and participants defined the nature of an adverse laser event.”

He reported having no financial disclosures.
