Late-breaking research: Suture spacing, hair regrowth, and EMPD

Saturday morning’s “Late-Breaking Research: Basic Science/Cutaneous Oncology/Pathology” (F055) and “Late-breaking Research: Procedural Dermatology” (F056) served as the backdrop to the newest research. Here’s a look at some of yesterday’s highlights:

Suture spacing: Suturing cutaneous surgical wounds every 2 mm is no improvement over 5 mm spacing in appearance. That is the conclusion of a head-to-head trial of suture spacing reported during the Late-Breaking Research sessions on Saturday.

“No difference in wound cosmesis was found between 2 mm and 5 mm running cutaneous suture spacing on the face and neck,” said Aunna Pourang, MD, University of California Davis School of Medicine. “This represents a potential savings in operative time, skin trauma, and suture material.”

Hair regrowth: Want to regrow hair in a patient with androgenic alopecia? A low-energy laser plus topical finasteride may help.

“A low-energy, high-density protocol using a 1550 nm laser successfully induced hair follicle growth in patients with alopecia,” said Margit Juhasz, MD, University of California Irvine School of Medicine. “Effective therapies for hair loss are lacking. Fractional photothermolysis represents a new frontier. Combination with topical finasteride was more effective in maintaining regrowth than topical minoxidil.”

Reducing EMPD: A novel staining technique may help reduce recurrence of extramammary Paget’s Disease (EMPD) treated with either standard Mohs micrographic surgery or a modified procedure with wide margins. Conventional Mohs excision for EMPD has a 10.4% recurrence rate.

“The issue is difficulty in visualizing EMPD,” said Julie Bittar, Indiana University School of Medicine. “Staining with cytokeratin 7 improves visualization and improves margins. In a trial with 45 patients and mean follow-up of 45 months, we had no recurrences.”
