Menopause 2019 Jan 14. Epub 2019 Jan 14.

University of California, Irvine, CA.

Objective: The treatment of genitourinary syndrome of menopause (GSM) includes prescription hormone therapy, nonhormonal over-the-counter products, and most recently, laser treatment. Although the Food and Drug Administration has cleared fractional carbon dioxide (CO2) laser for a variety of dermatologic and gynecologic indications, lasers have not to date, been approved for use for vulvar/vaginal atrophy, or sexual dysfunction.

Methods: Four case studies that were referred to a tertiary sexual medicine center regarding laser treatment complications for GSM are reported. Read More

Postinflammatory hyperpigmentation (PIH) and erythema are the most common adverse effects associated with laser treatment, particularly in dark-skinned individuals. Several methods have been used to prevent or minimize these adverse effects; however, to date, no definitive precautions/strategies are known to prevent post-laser PIH and erythema. We investigated whether the topical application of the α-adrenergic receptor agonist brimonidine could reduce laser treatment-related complications such as erythema and PIH. Read More

Acne is a chronic disease of the pilosebaceous units, presenting as inflammatory or noninflammatory lesions, affecting primarily the face but also the back and chest. The mainstay of treatment remains topical retinoids, benzoyl peroxide, azelaic acid, antibiotics, and isotretinoin, many of which result in poor compliance, lack of durable remission, and incur adverse effects. The use of lasers to treat acne is continuously increasing because of their minimal complications, limited number of office-based treatments required, potential benefits of simultaneously treating acne scarring, and the rapid onset of results.

Introduction: Some publications have shown good aesthetic results for scars through the early application of fractional CO lasers on elective surgery scars. The aim of this randomized, double-blinded clinical trial was to compare the aesthetic quality of the scar from a group of patients submitted to super-pulsed fractional CO laser applications (10,600 nm fractional CO , set at a density of 20% and an energy of 10 mJ, a scanner of 03 × 03 mm, and a pulse repetition time of 0.3 seconds) in contrast with the other group that used only the silicone gel on the scar after plastic surgery.

Melasma, also known as chloasma or mask of pregnancy, presents clinically as hyperpigmented skin areas, which develop mostly in the face as a consequence of increased synthesis of melanin. The established treatment options, including topically applied agents and the use of various laser systems, mostly result in improvement but not in complete remission of the lesions. Because of its significant impact on quality of life and the limited effectivity of available treatment options, the management of melasma is challenging for the treating physician. Read More

For most children and adolescents who have developed symptomatic scars, cosmetic concerns are only a portion of the motivation that drives them and their caregivers to obtain treatment. In addition to the potential for cosmetic disfigurement, scars may be associated with a number of physical comorbidities including hypertrichosis, dyshidrosis, tenderness/pain, pruritus, dysesthesias, and functional impairments such as contractures, all of which may be compounded by psychosocial factors. Although a plethora of options for treating scars exists, specific management guidelines for the pediatric and adolescent populations do not, and evidence must be extrapolated from adult studies.
