Blue light-emitting diodes for the treatment of localized vitiligo: A retrospective study.

BACKGROUND: Vitiligo is an autoimmune dermatological disease characterized by hypopigmented macules. Treatments include topical agents, phototherapy, and laser therapies. Different lasers should be individually chosen regarding location, extent, activity of the disease. AIMS: This article aims to demonstrate how blue LED is effective and safe, as its wavelength is very close to the UV spectrum (415 nm vs. 400 nm), but, unlike UV therapy, blue LED have not shown any long-term cancerogenic side effects. PATIENTS/METHODS: We treated 30 patients affected by vitiligo localized on different anatomical areas with blue light-emitting diodes. RESULTS: Complete repigmentation occurred in 75.33% of treated patients (22 out of 30 patients, 14 males, and 8 females). Partial repigmentation occurred in the remaining patients. CONCLUSIONS: Blue LED light may be a safe and well-tolerated way to induce repigmentation in patients affected by vitiligo.

Fractional Q-Switched 1064 nm Laser for Treatment of Atrophic Scars in Asian Skin.

Background and Objectives: Asian patients with Fitzpatrick skin type III-IV are a less studied subtype of patients in the medical literature. Q-Switched, 1064 nm neodymium-doped yttrium aluminum garnet (Nd: YAG) laser with a fractionated beam profile (QSF) is a new modality that was reported to be effective in the treatment of scars. This study aims to evaluate the efficacy and safety of QSF Nd: YAG laser in treating scars in Asian patients. Materials and Methods: A total of 29 Subjects were treated with 1064 nm QSF laser. Each patients had three treatments with a fractionated microlens array handpiece every 8 weeks). Efficacy of treatment was evaluated using the Goodman and Baron's quantitative grading scale before and 3 months after the last treatment. Results: All 29 patients treated had significant improvement of acne scars according to Goodman and Baron's Quantitative Global Acne Scarring Grading System. No side effect has been observed except some minor erythematous reactions in three patients. Conclusions: Our results confirm that the 1064 nm QSF Nd: YAG laser is a safe and effective technique for treating scars in Asians.

Combination of Specific Vascular Lasers and Vascular Intense Pulsed Light Improves Facial Telangiectasias and Redness.

Background and objectives: Facial telangiectasias are dilated blood vessels that can represent a cosmetic issue for patients. They may be associated with other conditions, such as rosacea. Laser and light treatments are nowadays becoming a cornerstone in the management of these lesions. Materials and Methods: In total, 68 patients seeking medical treatment for facial telangiectasias were enrolled from 1 March 2019 to 1 March 2020 at the Dermatological Unit of Magna Graecia University (Catanzaro, Italy). A protocol consisting of a 1064 Nd:YAG laser for darker blue telangiectasias and 532 nm Nd:YAG for red lesions followed by intense pulsed light with an optimized spectrum for vascular lesion 3 weeks after the first procedure was proposed. A three-month follow-up visit assessed patient's satisfaction using a visual analog scale (VAS). Two dermatologists measured clinical results using a 4-point scale, comparing pictures before treatment and at follow-up. Results: A total of 68 patients (32 males and 36 females) completed the study, performing all requested treatments. No severe side effects were reported. Patient satisfaction was very high (8.15 ± 1.05 out of a 10-point VAS scale), as well as dermatologists' clinical evaluations (2.19 ± 0.74 out of 3). Conclusions: The combination of vascular lasers and Vascular Intense Pulsed Light acting specifically on small blood vessels may help to improve the aesthetic outcome, reducing side effects. A prospective study with a larger number of participants will be necessary to confirm this study's findings.

Combined CO2 and dye laser technique in the treatment of outcomes due to flap necrosis after surgery for basal cell carcinoma on the nose.

BACKGROUND AND OBJECTIVE: Basal cell carcinoma (BCC) is the most frequent cutaneous cancer worldwide, and the nasal area is the most commonly affected region. Skin flaps are usually performed to achieve radical results, but various adverse events often occur. The necrosis of the skin flap is one of the most frequently observed, resulting in scars and anti-aesthetic outcomes. Ablative and non-ablative lasers have been proposed to improve scars resulting from surgical failure and skin flap necrosis. STUDY DESIGN/MATERIALS AND METHODS: This study aims to evaluate a new laser protocol combining ablative CO2 -laser with flashlamp pulsed dye laser for the treatment of nasal scars resulting from the necrosis of flap that occurred after surgery. Twelve patients were enrolled in the study, and a total of five laser sessions were planned, spaced from 14 days to 1 month apart. RESULTS: Seven out of 12 patients underwent all the five laser sessions planned, while 5/12 patients achieved optimal cosmetic results within the fourth session. Eighty percent of the patients reported good/optimal cosmetic results, and no significant side effects were observed during the study. CONCLUSION: Combining fractionated CO2 laser with flashlamp pulsed dye laser represents a new effective modality for treating skin flap necrosis after BBC removal, representing a valid alternative to other surgical procedures.

A giant epidermal nevus of the face treated with a CO2 and dye laser combination: a case report and literature review.

Epidermal nevi (EN) are cutaneous hamartomas present at birth, usually occurs in the trunk, the face, or the limbs, appearing as a patch of overgrowing skin. They may be small and localized, but they may interest extensive areas of the body. A 20 years old man came to our attention for an EN interesting all the face. The treatment protocol consisted of a session of CO2 laser in order to vaporize thicker areas, followed by a session of dye laser on the area to prevent scarring. This treatment was performed under local anesthesia and sedation in three surgical sessions spaced 3 months from each other. Two sessions of dye laser spaced apart 6 months were performed during follow-up to further improve the esthetic outcome. The patient was followed for 2 years with no recurrence. Although surgery is still considered the gold standard in EN management, it is not always feasible. This novel combination technique can obtain optimal cosmetic results with no relapse within the period of follow up. Although further trials on a more significant number of patients are required, the combination of CO2 and dye laser promises to become a valid therapeutic alternative when treating giant EN of the face.

(1) Benign hyperpigmentations are a common problem in cosmetic dermatology. Melasma, solar lentigo, and other acquired hyperpigmentations represent an aesthetic issue for an increasing number of patients. The gold standard in managing this condition is currently 1064/532 nanometers (nm) Q-Switched lasers. This study reports our experience on the use of a Q-switched laser with a nanosecond pulse to treat these conditions. (2) Methods: A total of 96 patients asking for benign hyperpigmentation removal were consecutively enrolled at the Magna Graecia University of Catanzaro and Tor Vergata University of Rome. Treating parameters were the following: 1064 nm with a pulse duration of 6 nanoseconds (ns) for dermic lesions and 532 nm with 6 ns for epidermal ones. Up to five treatments with a minimum interval between laser treatments of thirty days were performed. A follow-up visit three months after the last session assessed patient satisfaction with a Visual Analogue Scale (VAS). Two blinded dermatologists assessed the cosmetic result using a five-point scale comparing pictures before treatment and at follow-up. (3) Results: 96 patients were included; 47 participants were women (49.0%) and 49 men (51.0%). The mean reported age was 50.0 ± 17.3 years. All patients reached a good to complete hyperpigmentation removal at the dermatological evaluation with a mean VAS score of 8.91 ± 1.07. (4) Conclusions: Q Switched 1064/532 nm laser may be considered the gold standard treatment for benign hyperpigmentations. Our results confirm the literature findings on the effectiveness of these devices.

Q-Switched 1064/532 nm Laser with Nanosecond Pulse in Tattoo Treatment: A Double-Center Retrospective Study.

Tattoo removal is a well-established procedure in dermatology. Lasers represent the gold standard in the management of this condition nowadays. In this study, we report our experience on the use of a Q-switched nanosecond source. A total of 52 patients were consecutively enrolled in performing tattoo removal at Magna Graecia University of Catanzaro and Tor Vergata University of Rome. Black and blue tattoos were treated with a 1064 nm laser, with a pulse duration of 6 ns and a fluence up to 10 J/cm2, while colored tattoos were treated with sessions of 532 nm laser, with a pulse duration of 6 ns and a fluence up to 5 J/cm2. Up to nine treatments with a minimum interval of 8 weeks between each session were performed. A six-month follow-up visit assessed patient satisfaction (Visual Analogue Scale). Overall clinical result was assessed with a clinical evaluation by two blinded dermatologists using a 5-point scale, comparing pictures before treatment and at follow up. A total of 52 patients were included and analyzed: 30 females (57.7%) and 22 males (42.3%). Mean age was 43.7 ± 12.7 years. According to Fitzpatrick's skin classification, 16 individuals (30.8%) were type II, 15 (28.8%) were type III, and 21 (40.4%) were type IV. Most of the treated tattoos were carried out by professionals. The mean number of sessions required to obtain a result was 4.6 ± 2.5, and the final tattoo removal rate was 60% or higher, with 51.9% of the patients reporting highest satisfaction scores Q-Switched 1064/532 nm laser may be considered today as the gold-standard treatment for tattoo removal. Our results confirm literature findings of the safety and effectiveness of these devices.

Combination of Laser Therapy and Photodynamic Therapy with 5-Aminolevulinic Acid Patch for the Treatment of Actinic Cheilitis.

Background: Actinic cheilitis (AC) is a premalignant lesion of the lips that can evolve into squamous cell carcinoma. Among nonsurgical treatments, photodynamic therapy (PDT) with 5-aminolevulinic acid (ALA) patch might represent a new noninvasive therapeutic approach for AC. Objective: We sought to investigate the potential role of fractional CO2 laser pretreatment in boosting ALA penetration and distribution into AC treated with PDT. Methods: We report a case of a woman with AC on the lower lip, treated with ablative fractional CO2 laser to boost drug delivery of 5-ALA patch before PDT treatment. Reflectance confocal microscopy was performed to assess diagnosis and treatment response. Results: We detected a good clinical and cosmetic outcome after two applications of combined treatment. Erythema, crust, and edema were reported as side effects. Conclusions: This case report shows that ablative fractional CO2 laser-assisted PDT might be an effective therapeutic alternative for patients with AC who refuse or are contraindicated for surgical procedures.

Fractional CO2 laser-assisted topical rifamycin drug delivery in the treatment of pediatric cutaneous leishmaniasis.

Cutaneous leishmaniasis is challenging to treat. Various drugs have been proposed to manage this condition, with variable results. In this case report, we describe laser-assisted delivery of rifamycin to treat this infection. Two sessions of fractional CO2 laser were performed one month apart. Each was followed by a topical application of rifamycin for three days. Resolution with minimal scarring was obtained, suggesting this technique might be safe and effective in treating cutaneous leishmaniasis.

Long-Term Follow-Up for Q-Switched Nd:YAG Treatment of Nevus of Ota: Are High Number of Treatments Really Required? A Case Report.

Objective: Q-switched laser is considered a gold standard treatment for Nevus of Ota (NO). We report how few laser sessions in long intervals of time may achieve satisfying outcomes reducing the rate of possible procedure-linked side effects such as burning, cornea injuries, or hyperpigmentation. Background: NO represents a congenital dermal melanocytosis in the trigeminal distribution majorly occurring in Asian individuals. Multiple reports have shown efficacy and safety of Q-switched laser for the treatment of this condition, but they were based on an empiric regimen, often leading to unnecessary overtreatments. At the best of our knowledge, no long-term follow-up observations of single laser sessions have been conducted to assess the proper intervals and number of treatments. Materials and methods: A 36-year-old Asian woman, Fitzpatrick skin type IV with clinical diagnosis of NO, was treated with 1064 nm 6 ns Q-switched laser one session per year for a total of two sessions. Clinical result was valued by two physicians independently using standardized and polarized light. No use of general anesthesia or sedation was needed in our experience. Corneal shields have been used. Results: After only two sessions of the Q-switched laser performed 1 year apart, the result was excellent with a 95% of clinical response. No side effect was observed. Conclusions: In our experience, Q-switched Nd:YAG laser is an effective treatment for NO with no necessity of high number of treatments. A larger population is needed to confirm this preliminary result.

Daylight photodynamic therapy with 5-aminolevulinic acid 5% gel for the treatment of mild-to-moderate inflammatory acne.

BACKGROUND: Acne vulgaris is a chronic inflammatory disease that frequently occurs in adolescence. This common condition is often treated with topical or systemic therapies according to severity. Photodynamic therapy (PDT) with topical delta-aminolaevulinic acid is a novel drug-sparing, but time-consuming approach. Recently, sunlight exposure has been considered a quicker, safer, cheaper and more agreeable alternative light source for PDT, but efficacy has only been proven in the oncological field. This study aimed to evaluate the efficacy and tolerability of daylight PDT (DL-PDT) for the treatment of inflammatory acne vulgaris of face, chest and trunk lesions. METHODS: Twenty patients with mild-to-moderate acne vulgaris were enrolled and treated with a topical gel based on 5% delta-aminolaevulinic acid, administered 4 times at 14-day intervals. Efficacy was assessed with mean lesion count, Physician Global Assessment (PGA), Investigator's Global Assessment (IGA) and patients' self-assessment (10-point scale). RESULTS: Compared to T0, mean inflammatory lesions count decreased in all patients at FU1, from 16.7±4.4 to 5.2±3.3 (P). No adverse events were reported, and no patients were lost to follow-up. PGA results of "excellent" or "good" improvement were reported in 95% at T3 and 90% at FU1. Patients' self-assessments was 7.6±1.0 (T3). Discomfort was 0.5±0.2 (T3 and FU1). CONCLUSIONS: DL-PDT seems to be an effective and tolerable therapy for the treatment of mild-to-severe inflammatory acne. This novel regimen seems to be a viable option in the panorama of acne therapies.

This study aims to assess the safety and efficacy of the fractional micro-ablative CO2 laser in the treatment of penile LS. Case Presentation: Five treatments with the fractional CO2 laser were performed on one 69-year-old man affected by penile LS. A significant improvement in symptomatology was noted after the first treatment session. Complete clinical remission was achieved 14 weeks after the last treatment. Conclusion: The fractional micro-ablative CO2 laser may represent a practical therapeutic approach in penile LS.

New Insight in Noninvasive Rejuvenation: The Role of a Rhodamine-Intense Pulsed Light System.

Background: Rhodamine-intense pulsed light (r-IPL) is a noncoherent, noncollimated, polychromatic light energy optimized for a double-peak wavelength emission, ranging between 550-680 and 850-1200 nm. Traditional IPL works within visible and infrared spectra, targeting hemoglobin and melanin, are effective to treat rosacea and pigmentary disorders. r-IPL, a new technology in dermatology, emits high-intensity light with a wavelength peak similar to the one of the pulsed dye lasers, showing a good safety and efficacy profile in nonablative photorejuvenation. Objective: Assess efficacy and safety of r-IPL on photodamaged facial skin showing hyperpigmentation, telangiectasias, fine lines, and textural changes. Methods: Five sessions of r-IPL treatment (fluence ranged between 13.5 and 14 J/cm2) have been performed on one 75-year-old lady affected by facial photodamaged skin. Efficacy of treatment was evaluated using the Fitzpatrick Elastosis and Wrinkles Scale (FEWS) and the Global Aesthetic Improvement (GAI) Scale assessed by an investigator, compared with baseline. Treatment safety and tolerance were also evaluated using the Visual Analog Scale (VAS). Results: Photographic and multispectral evaluation demonstrated relevant improvement (vascular, pigment, and texture) of photodamaged facial skin. One month after the last treatment, significant improvement in facial wrinkle and texture was noted. FEWS scores decreased significantly from 7 to 2. According to the GAI scale, the patient had an improvement in skin texture. Immediate response included mild-to-moderate erythema and only trace-mild edema in the treatment area. Pain during the treatment was minimal with a mean VAS pain score of 3/10. No other adverse events were reported. No post-treatment downtime was recorded. Conclusions: r-IPL may represent a valid therapeutic approach in noninvasive photorejuvenation.

Q-switched Nd:YAG laser for cosmetic tattoo removal.

Laser is a widely accepted tool for tattoo removal, with standardized treatment protocols. Nevertheless, cosmetic tattoo removal may be challenging, because tattoos are performed in proximity of "sensitive" areas and because the ink used in cosmetic tattoos may contain substances that are not standardized and may modify their color at a high temperature. In this case series, we aim to evaluate the effectiveness of Q-switched (QS) Nd:YAG laser for cosmetic tattoo removal. Our study included 20 patients with cosmetic tattoos of lips, eyebrows, and eyeliners treated with QS Nd:YAG laser. Before treatment, an accurate preoperative assessment was performed, taking into account both patient and tattoo characteristics. Complete tattoo removal was obtained in all the cases and no major complications occurred. Adverse events were mild, mostly represented by erythema. All patients reported a high level of satisfaction. Selective photothermolysis enables complete tattoo removal, even in the case of cosmetic tattoos. However, cosmetic tattoos require a personalized treatment based on an accurate preoperative assessment which takes into account both patient and tattoo characteristics. QS Nd:YAG laser may be considered a good choice in the treatment of cosmetic tattoos, because it enables complete removal with acceptable secondary effects.

Kleresca® biophotonic platform utilizing fluorescent light energy effectively decreased the inflammatory and erythematous reaction common in rosacea subtypes 1, 2, and 3. Kleresca® may be considered as a single treatment for rosacea, targeting multiple features, or combined with invasive methods for an enhanced normalizing and healing profile of the skin.

Fractional CO2 Laser: From Skin Rejuvenation to Vulvo-Vaginal Reshaping.

BACKGROUND: The CO2 laser has become the gold standard treatment in dermatologic surgery for the treatment of a large number of skin and mucosal lesions. The introduction of the fractional micro-ablative technology represented an integration to the ablative resurfacing technique, reducing the healing time and the side effects. OBJECTIVE: Vaginal rejuvenation performed with this technique is a minimally invasive procedure that stimulates internal tissues of the female lower genital tract to regenerate the mucosa, improving tissue trophism and restoring the correct functionality. METHODS: In our experience, 386 menopausal women affected with vulvo-vaginal atrophy (VVA) were treated with three section of fractional micro-ablative CO2 laser. RESULTS: After three treatments, patients reported a complete improvement of the symptoms (59.94% dryness, 56.26% burn, sensation, 48.75% dyspareunia, 56.37% itch, 73.15% soreness, and 48.79% vaginal introitus pain). CONCLUSIONS: Fractional micro-ablative CO2 laser seems to reduce symptoms related to vaginal atrophy. The beneficial effects were reported just after the first session and confirmed 12 months after the last session.
