Six recent developments in dermatological lasers

Study results on the use of dermatological lasers for treating port-wine stains were among recent developments reported on Healio.com.

Other research included findings that Q-switched ruby laser and triple-combination therapy cream were effective in reducing solar lentigines:

Improvement in port-wine stains seen with 595-nm pulsed dye laser

Patients with flat and hypertrophic port-wine stains showed significant improvement after multiple treatments with a 595-nm pulsed dye laser, according to recent research.

Sujay Khandpur, MBBS, MD, DNB, MNAMS, from the department of dermatology and venereology at the All India Institute of Medical Sciences in New Delhi, India, and colleagues analyzed 74 flat and 24 hypertrophic port-wine stains, ranging in color from pink to purple, in patients with skin types IV and V.

Early-onset hypertrophic port-wine stains had poor response to laser treatment

Port-wine stains with early-onset hypertrophy were associated with complications and had a low response to laser treatment, according to published study results.

Researchers conducted a retrospective study of 98 patients with facial port-wine stains (PWS) and underlying hypertrophy that developed before the age of 18 years. Read more

Continuous wave KTP laser effective for treating xanthelasma palpebrarum

Continuous wave potassium titanyl phosphate laser therapy was safe and effective treatment for xanthelasma palpebrarum, according to published study results.

“Xanthelasma paplebrarum are the most common cutaneous xanthoma, presenting as yellow plaques that occur most commonly near the inner canthus of the upper and lower eyelid,” researchers in the Netherlands wrote. Read more

Triple-combination cream comparable to laser in treating solar lentigines

Q-switched ruby laser and triple-combination therapy cream were effective in reducing solar lentigines; however, the laser provided faster and longer-lasting results, according to recently published study results.

Researchers in Zurich, Switzerland, treated 15 patients (14 women; mean age, 61 years) with symmetrically distributed solar lentigines on the back of both hands. Read more

Laser treatments not associated with increased hair count in alopecia

Treatment for alopecia areata with a neodymium:yttrium aluminum garnet laser or a fractional carbon dioxide laser did not increase hair count when compared with a control patch, according to recently published study results.

Researchers in Turkey studied 32 patients (19 men, mean age, 24.22 years) with alopecia areata including the scalp. Read more

Low-fluence QS Nd:YAG laser effective in melasma, but with high recurrence rate

Low-fluence Q-switched neodymium-doped yttrium aluminum garnet laser was effective and safe in treating melasma; however, there was a high recurrence rate following treatment, according to recently published study results.

Researchers studied 20 healthy Brazilian women aged 18 to 17 years who had Fitzpatrick skin types III to V and mild-to-severe facial melasma. Read more
