Abstract
Background: Q-switched 1064 nm Nd:YAG laser (1064-QSNYL) is efficient in rejuvenating photoaging skin, and microRNAs (miRNAs) participate in this process. Objective: In this study, we aimed to explore the effects of 1064-QSNYL on miR-196b-5p, TGF-beta receptor II (TGFBR2), and SMAD7 in the photoaging skin of rats. Methods: The relationship between miR-196b-5p and TGFBR2 in HaCaT cells was detected by real-time PCR and western blotting. A skin photoaging model was established in Wistar rats using ultraviolet (UV) radiation (UVR). Dermoscopy, hematoxylin-eosin (HE) staining, Sirius red staining, and hydroxyproline content were used to observe the effect of UVR on rat skin. The 1064-QSNYL was used for skin rejuvenation. The expression of COL3A1, TGFB1, TGFBR2, SMAD2, SMAD3, and SMAD7 was detected by real-time PCR and/or western blotting. Results: TGFBR2 was a specific target of miR-196b-5p in the skin. In HaCaT cells and the photoaging skin of rats, 1064-QSNYL treatment upregulated COL3A1 and TGFBR2 and downregulated SMAD7 and miR-196b-5p. Conclusions: We showed for the first time that 1064-QSNYL treatment rejuvenates photoaging rat skin by regulating TGFBR2 and SMAD7. Downregulation of miR-196b-5p assists in this process by targeting and upregulating TGFBR2.

J Cosmet Dermatol 2020; 20:497-505. [PMID: 32593217 DOI: 10.1111/jocd.13580] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2020] [Revised: 06/16/2020] [Accepted: 06/22/2020] [Indexed: 11/28/2022]
Abstract
BACKGROUND Laser treatment has emerged as a novel treatment modality for onychodystrophy. Only a few small series have assessed the efficacy of laser treatment in onychodystrophy, most of which were case reports. The therapeutic effect of the 1064 nm neodymium-doped:yttrium aluminum garnet (Nd:YAG) laser for onychodystrophy has been demonstrated. Recently, the picosecond Nd:YAG (PSNY) laser has been introduced to improve various skin disorders. AIMS The aim of this study was to verify the efficacy of a 1064 nm PSNY in management of idiopathic onychodystrophy. METHODS We present a case series of dystrophic nails treated with a PSNY for onychodystrophy improvement. Planimetry using ImageJ software was used to calculate lesion reduction and proximal clear nail growth. Clinical improvement was assessed using a 5-point Global Assessment Scale (GAS). Adverse events were also assessed. RESULTS Twenty-five patients (11 males and 14 females) with a total of 128 nails (94 finger nails and 34 toe nails) were treated. The mean treatment number was 8.7 ± 6.2, and the mean total duration of treatment was 33.4 ± 34.6 weeks. The average proportion of the lesion area decreased significantly (from 65.9% to 46.6%) after PSNY treatment (P < .001). The mean GAS (3.16 ± 1.18) exhibited fair improvement, and there were no serious adverse events. CONCLUSION The 1064 nm PSNY laser can provide fair improvement for onychodystrophy with a good prognosis at least during the follow-up period and optimal cosmetic results in Asian patients.

Objective evaluation of the efficacy of a non-ablative fractional 1565 nm laser for the treatment of deliberate self-harm scars. Lasers Med Sci 2017; 33:241-250. [PMID: 29080008 DOI: 10.1007/s10103-017-2348-x] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2017] [Accepted: 10/01/2017] [Indexed: 10/18/2022]
Abstract
Scars resulting from deliberate self-harm (DSH) represent therapeutically challenging forms of scarring due to their highly variable patterns, with no official therapeutic guidelines available. In this pilot study, we aimed to evaluate the effectiveness and safety of a non-ablative fractional Er:glass 1565 nm laser, as a potential new, minimal-invasive approach for the improvement of DSH scars. Sixteen Caucasians suffering from mature DSH scars were included in this clinical study. Patients received a total of three treatments using a non-ablative fractional 1565 nm Er:glass laser every 4 weeks, employing two passes (300 μbeams/cm2, 40 mJ, onto the scar; 150 μbeams/cm2, 50 mJ, overall area). Measurements included questionnaires (DLQI, POSAS), digital photography, and objective three-dimensional analysis using PRIMOS and VECTRA software at baseline, 1 and 6 months after treatment. PRIMOS objective measurements showed highly significant changes in scar surface with a reduction of atrophic lesions by 27.5% at 6 months follow-up (FU), a decrease in scar height by 42.7% at 6 months FU, resulting in an overall diminished skin irregularity dropping from 678.3 μm at baseline to 441.6 μm throughout the course of the study (p = <0.001 respectively). Improvements in objective measurements were supported by clinical evaluation of scar parameters and showed a strong correlation with enhanced life quality of treated patients. Procedures were well-tolerated, with no lasting negative side effects and little to no downtime. The use of a fractional non-ablative 1565 nm Er:glass laser represents a promising and safe approach for the therapy of DSH scars. Although these scars will never fully resolve, their appearance can be significantly improved to a cosmetically and socially more acceptable appearance.

Abstract
BACKGROUND AND OBJECTIVE Non-ablative fractional lasers (NAFL) generate microscopic non-contiguous columns of thermal injury in the dermis, resulting in collagen remodeling. This manuscript details our experience with a novel 1,565 nm scanned, erbium-doped fiber NAFL for the treatment of facial photodamage. STUDY DESIGN/MATERIALS AND METHODS A prospective, open-label clinical trial was conducted at two clinical sites in the United States on 16 female subjects with a mean age of 49.6 years, Fitzpatrick skin types II to IV, and a baseline Fitzpatrick-Goldman Wrinkle and Elastosis Score (FGWES) of 3-6. Each subject received three treatments at 4-5 week intervals with follow-up assessments at 1, 3, and 6 months after the last treatment. RESULTS The mean FGWES demonstrated a statistically significant decrease from baseline both at 3 months (-0.58 ± 0.23, P = 0.02) and 6 months (-0.66 ± 0.22, P = 0.008) after the last treatment. Fifty percent (95%CI [24.21%, 68.49%]) of subjects showed a significant (at least 1 grade) improvement in FGWES from baseline at 3-month follow-up. At least 72% of subjects perceived the results as "moderate" to "very good" at 3 months post-treatment, with comparable satisfaction rates. Treatments were not associated with a high level of pain or discomfort and typical downtime was less than 2 days. No unexpected adverse events or serious adverse events were reported. CONCLUSION The 1,565 nm erbium-doped scanned NAFL is an effective treatment for facial wrinkles with a favorable recovery and side effect profile.

Abstract
Aim. To evaluate the effect of Low Level Laser Therapy (LLLT) on human gingival fibroblasts in terms of proliferation and growth factors' secretion (EGF, bFGF, and VEGF). Materials and Methods. Primary cultures of keratinized mucosa fibroblasts were irradiated by a Nd:YAG laser 1064 nm with the following energy densities: 2.6 J/cm2, 5.3 J/cm2, 7.9 J/cm2, and 15.8 J/cm2. Controls were not irradiated. Cultures were examined for cell proliferation and growth factors' secretion after 24, 48, and 72 hours. All experimental procedures were performed in duplicate. Data were analyzed by Student's t-test (p < 0.05). Results. All laser-irradiation doses applied promoted a higher cell proliferation at 48 hours in a dose-response relationship compared to controls. This difference reached statistical significance for the cultures receiving 15.8 J/cm2 (p = 0.03). Regarding EGF, all laser irradiation doses applied promoted a higher secretion at 48 hours in a reverse dose-response pattern compared to controls. This difference reached statistical significance for the cultures receiving 2.6 J/cm2 (p = 0.04). EGF levels at the other time points, bFGF, and VEGF showed a random variation between the groups. Conclusion. Within the limits of this study, LLLT (Nd:YAG) may induce gingival fibroblasts' proliferation and upregulate the secretion of EGF. Further studies are needed to confirm these results.

Abstract
Several studies demonstrate the benefits of low-power light therapy on wound
healing. However, the use of LED as a therapeutic resource remains
controversial. There are questions regarding the equality or not of biological
effects promoted by LED and LASER. One objective of this review was to determine
the biological effects that support the use of LED on wound healing. Another
objective was to identify LED´s parameters for the treatment of wounds. The
biological effects and parameters of LED will be compared to those of LASER.
Literature was obtained from online databases such as Medline, PubMed, Science
Direct and Scielo. The search was restricted to studies published in English and
Portuguese from 1992 to 2012. Sixty-eight studies in vitro and in animals were
analyzed. LED and LASER promote similar biological effects, such as decrease of
inflammatory cells, increased fibroblast proliferation, stimulation of
angiogenesis, granulation tissue formation and increased synthesis of collagen.
The irradiation parameters are also similar between LED and LASER. The
biological effects are dependent on irradiation parameters, mainly wavelength
and dose. This review elucidates the importance of defining parameters for the
use of light devices.
