Study findings that platelet-rich plasma did not significantly improve female androgenetic alopecia was among the most-read articles of the past week on Healio.com/Dermatology and Healio.com/Aesthetics.
Other widely read articles included study findings that fractional microneedling radiofrequency was used to moderately treat rosacea and single-stage prosthetic breast reconstruction was a cost-effective operation compared with expander-implant breast reconstruction:
Platelet-rich plasma did not significantly improve female androgenetic alopecia
There was no significant improvement in hair mass index or hair count in women with female androgenic alopecia treated with platelet-rich plasma when compared with placebo; however, surveyed patients reported improvement with the treatment, according to recently published study results.
Researchers studied 26 women with Ludwig type II female androgenetic alopecia. Read more
Mohs micrographic surgery may be used for melanoma in situ beyond excision margins
Mohs micrographic surgery was used effectively to treat melanoma in situ exceeding traditional excision margins of 5 mm, according to published study results.
Researchers examined the long-term outcomes of 882 primary or recurrent melanoma in situ tumors (mean patient age, 62 years; 52.4% male) located on the trunk or proximal extremity and treated with Mohs micrographic surgery (MMS), and compared the outcomes with those of historical controls. Surgical margin intervals determined complete excision rates. Read more
Fractional microneedling radiofrequency used as rosacea treatment
Patients with mild-to-moderate rosacea experienced modest clinical and histologic improvement following fractional microneedling radiofrequency treatment, according to recently published study results.
Researchers in Seoul, South Korea, conducted a 12-week, prospective, split-face clinical trial of 21 patients (20 women, mean age, 42.9 years) with mild-to-moderate rosacea. Read more
Subsurface monopolar radiofrequency effectively reduces skin laxity on face, neck
Subsurface monopolar radiofrequency resulted in skin tightening of the face, neck and jawline, according to patient satisfaction surveys at 6 months following treatment, according to recently published study results.
Mitchel P. Goldman, MD, of Cosmetic Laser Dermatology, San Diego, and colleagues conducted a single-center retrospective chart review of 35 patients (29 women; average age, 63 years) who underwent a single subsurface monopolar radiofrequency treatment with the ThermiRF (Thermi Aesthetics) to multiple combinations of the face, cheeks, jawline and neck.

Single-stage breast reconstruction cost-effective compared with two-stage reconstruction
Single-stage prosthetic breast reconstruction was a cost-effective operation compared with expander-implant breast reconstruction, according to study results published in Plastic and Reconstructive Surgery.
“Prosthetic breast reconstruction is most commonly performed using the two-stage (expander-implant) technique,” Naveen M. Krishnan, MD, MPhil, of the department of plastic surgery, Georgetown University Hospital, and colleagues wrote. “However, with the advent of skin sparing mastectomy, and the use of acellular dermal matrices, one-stage prosthetic reconstruction has become more feasible.” Read more
