Ophthalmol Ther 2024; 13:1223-1237. [PMID: 38467993 DOI: 10.1007/s40123-024-00919-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2024] [Accepted: 02/20/2024] [Indexed: 03/13/2024] Open
Abstract
INTRODUCTION To assess the efficacy and safety of the combination of microblepharoexfoliation (MBE), intense pulse light (IPL) and meibomian gland expression (MGX) for treatment of meibomian gland dysfunction (MGD). METHODS This was a prospective, parallel-control trial conducted from April 2022 to January 2023. Participants were assigned to receive either three sessions of MBE-IPL-MGX treatment and home-based therapy (treatment group) or home-based therapy alone (control group). Outcome measures were assessed at baseline and after 2-month follow-up. RESULTS Seventy eyes of 70 patients were enrolled. MBE-IPL-MGX treatment achieved better improvements than home-based therapy in ocular surface disease index (OSDI) and symptom assessment in dry eye (SANDE) scores, noninvasive tear film break-up time (NIBUT), lipid layer grade (LLG), loss area meibomian gland (LAMG) and meibomian gland yielding secretion score (MGYSS). The mean differences between the two groups were as follows: OSDI (- 11.23 ± 4.68 points, P < 0.001), SANDE (- 24.63 ± 13.41 points, P < 0.001), NIBUT (1.3 ± 1.57 s, P = 0.033), LLG (0.4 ± 0.04 points, P = 0.003), LAMG (- 2.85 ± 1.69%, P = 0.023) and MGYSS (7.5 ± 2.32 points, P < 0.001). In addition, the increment (Δ) of MGYSS after MBE-IPL-MGX treatment was significantly higher in MGD grades 2 and 3 (all P < 0.001). CONCLUSIONS MBE-IPL-MGX treatment is an effective and well-tolerated procedure that improves dry eye symptoms and signs as well as meibomian gland secretions in patients with MGD. In addition, this treatment is recommended for MGD grades 2 and 3.

Dobroshi K. Using an intense pulsed light (IPL) module for the treatment of pigmented lesions. J Cosmet Dermatol 2024; 23 Suppl 1:27-32. [PMID: 38587313 DOI: 10.1111/jocd.16285] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2024] [Revised: 03/03/2024] [Accepted: 03/06/2024] [Indexed: 04/09/2024]
Abstract
BACKGROUND Pigmented lesions are largely benign and may lead to extreme distress. Various light and lasers may be used to treat pigmentation, often Q-switched lasers are considered the method of choice, while intense pulsed light (IPL) devices may offer a less invasive treatment with a shorter downtime. OBJECTIVE The purpose of this study is to evaluate the safety and efficacy of a narrowband IPL module for the treatment of pigmented lesions. METHODS A retrospective study of 20 patients with pigmented lesions underwent treatment with an IPL module. Treatment was assessed by blinded evaluation of clinical photographs using a GAIS scale of 0-10, as well as through patient satisfaction ratings on a scale of 0-10. Throughout the treatment, pain levels and adverse events were monitored. RESULTS The mean GAIS score was 7.55 ± 1.15 (mean ± SD), and the mean patient satisfaction score was 7.3 ± 1.26 (mean ± SD). There was a strong positive correlation between GAIS and patient satisfaction scores (r = 0.83), and no significant difference between them (p-value = 0.516). The number of treatments did not significantly affect GAIS and patient satisfaction scores (p-values 0.364 and 0.126). Additional positive unexpected outcomes were improved skin firmness and reduced wrinkles. CONCLUSION The results of the study indicate that the IPL module is both safe and effective in treating pigmented lesions and may have the potential to stimulate collagen production.

Abstract
Photodynamic therapy (PDT) is increasingly used in modern medicine. It has found application in the treatment of breast cancer. The most common cancer among women is breast cancer. We collected cancer cells from the breast from the material received after surgery. We focused on tumors that were larger than 10 mm in size. Breast cancer tissues for this quantitative non-contrast magnetic resonance imaging (MRI) study could be seen macroscopically. The current study aimed to present findings on quantitative non-contrast MRI of breast cancer cells post-PDT through the evaluation of relaxation times. The aim of this work was to use and optimize a 1.5 T MRI system. MRI tests were performed using a clinical scanner, namely the OPTIMA MR360 manufactured by General Electric HealthCare. The work included analysis of T1 and T2 relaxation times. This analysis was performed using the MATLAB package (produced by MathWorks). The created application is based on medical MRI images saved in the DICOM3.0 standard. T1 and T2 measurements were subjected to the Shapiro-Wilk test, which showed that both samples belonged to a normal distribution, so a parametric t-test for dependent samples was used to test for between-sample variability. The study included 30 sections tested in 2 stages, with consistent technical parameters. For T1 measurements, 12 scans were performed with varying repetition times (TR) and a constant echo time (TE) of 3 ms. For T2 measurements, 12 scans were performed with a fixed repetition time of 10,000 ms and varying echo times. After treating samples with PpIX disodium salt and bubbling with pure oxygen, PDT irradiation was applied. The cell relaxation time after therapy was significantly shorter than the cell relaxation time before PDT. The cells were exposed to PpIX disodium salt as the administered pharmacological substance. The study showed that the therapy significantly affected tumor cells, which was confirmed by a significant reduction in tumor cell relaxation time on the MRI results.

Abstract
Brain diseases present a significant obstacle to both global health and economic progress, owing to their elusive pathogenesis and the limited effectiveness of pharmaceutical interventions. Phototherapy has emerged as a promising non-invasive therapeutic modality for addressing age-related brain disorders, including stroke, Alzheimer's disease (AD), and Parkinson's disease (PD), among others. This review examines the recent progressions in phototherapeutic interventions. Firstly, the article elucidates the various wavelengths of visible light that possess the capability to penetrate the skin and skull, as well as the pathways of light stimulation, encompassing the eyes, skin, veins, and skull. Secondly, it deliberates on the molecular mechanisms of visible light on photosensitive proteins, within the context of brain disorders and other molecular pathways of light modulation. Lastly, the practical application of phototherapy in diverse clinical neurological disorders is indicated. Additionally, this review presents novel approaches that combine phototherapy and pharmacological interventions. Moreover, it outlines the limitations of phototherapeutics and proposes innovative strategies to improve the treatment of cerebral disorders.

Abstract
Dermatomyositis is an inflammatory myopathy characterized by typical skin findings. Cutaneous findings of DM include heliotrope eruption, Gottron papules, Gottron sign, poikiloderma, periorbital edema, facial swelling. The unique cutaneous manifestations of dermatomyositis are often resistant to conventional treatments. Narrowband intense pulsed light is a novel treatment that may reduce vasodilation. Furthermore, it may have a role in regulating inflammation associated with dermatomyositis. We present a case of cutaneous dermatomyositis that was successfully treated with narrowband intense pulsed light.

Abstract
BACKGROUND The popularity of social media appears to be increasing the acceptance of cosmetic treatments, prompting more consumers to seek cosmetic treatments. As the estimated prevalence of acne vulgaris among adult women may be as high as 54%, acne is commonly observed among patients presenting for cosmetic treatments. Concomitant treatment of acne in the aesthetic patient population will improve overall clinical outcomes. AIMS The goal of this work was to deliver a high-quality ethical and evidence-based educational program to physicians and adjunctive health care providers to advance patient care. METHODS This paper is based on a webcam presentation with roundtable discussion by several notable experts in their field. RESULTS A range of topical medications, injectable products, chemical peels, and energy-based devices are available for treating acne vulgaris. In most instances, these are compatible with rejuvenation procedures in the aesthetic patient. CONCLUSION The growth of social media is raising awareness of aesthetic procedures and appears to be increasing the number of patients seeking aesthetic treatment. Educating patients about the importance of treating acne vulgaris can improve overall treatment outcomes. In most instances, the presence of acne is not a barrier to aesthetic care.

Abstract
In this report the use of eye cosmetic products and procedures and how this represents a lifestyle challenge that may exacerbate or promote the development of ocular surface and adnexal disease is discussed. Multiple aspects of eye cosmetics are addressed, including their history and market value, psychological and social impacts, possible problems associated with cosmetic ingredients, products, and procedures, and regulations for eye cosmetic use. In addition, a systematic review that critically appraises randomized controlled trial evidence concerning the ocular effects of eyelash growth products is included. The findings of this systematic review highlight the evidence gaps and indicate future directions for research to focus on ocular surface outcomes associated with eyelash growth products.

Abstract
BACKGROUND The mechanism of intense pulsed light action on the skin is based on selective photothermolysis. The light delivered to the tissue is scattered and absorbed by chromophores that absorb a beam of radiation of a specific length. The skin reflectance changes depending on the physiological state of the tissue, as shown by the hyperspectral camera. The aim of the study was to assess the hyperspectral reflectance of acne skin before and after intense pulsed light (IPL) therapy and to compare it with the reflectance of healthy skin. MATERIALS AND METHODS The study involved 27 volunteers with diagnosed moderate acne. The control group consisted of 20 people without acne lesions. All acne volunteers underwent a series of four treatments using IPL at weekly intervals. The volunteers with acne lesions were photographed before the series of treatments and a week after the 4th treatment. RESULTS Acne skin shows lower reflectance than healthy skin. Acne skin after IPL therapy is characterized by a higher reflectance compared to acne skin before the therapy and resembles the reflectance of the skin of the control group. A statistically significant difference was found between the acne skin before the treatments and the skin of the control group. CONCLUSIONS The effect of IPL therapy on acne skin is the increase of its reflectance by reducing the number of chromophores, which brings it closer to the reflectance value of healthy skin. Hyperspectral imaging allows for: the evaluation of the treated skin at each stage, a precise selection of the light wavelength depending on the problem, and therefore, for optimizing the number of irradiations and increasing the safety of the therapy.

Abstract
Background Cutaneous leishmaniasis (CL) is a common parasitic disorder that is endemic in many countries. There is no completely effective treatment for this condition, but pentavalent antimony compounds are regarded as the main treatment. Different laser types have been used for treatment of CL with variable success but to our best knowledge, there is no published paper regarding use of intense pulsed light (IPL) for treatment of CL. Materials and Methods In this randomized, single-blind clinical trial study, we compared the efficacy of intralesional glucantime alone versus intralesional glucantime plus weekly IPL for treatment of 54 patients with confirmed cutaneous leishmaniasis for a maximum of eight weeks as a randomized, clinical trial. Results Although it was not statistically significant, combination treatment was more effective than intralesional glucantime alone (P > 0.05). However, the velocity of healing was significantly higher in the IPL plus intralesional glucantime alone versus glucantime alone. No side effect was observed in both groups. Discussion To better evaluate the efficacy of IPL, more studies with a higher number of patients and using various IPL filters are recommended.

Abstract
Introduction: Different therapies have been applied to keloids and hypertrophic scars. Intense pulsed light (IPL) has recently been used but the evidence is limited. This study was to evaluate the effectiveness and safety of IPL as monotherapy for keloids and hypertrophic scars. Methods: This was a before-and-after interventional study on 16 patients with 50 scars who underwent IPL. Seven scars receive one IPL session, seven received two sessions, and 36 received three sessions. Outcomes were evaluated by the Vancouver Scar Scale (VSS), Patient and Observer Scar Assessment Scale (POSAS), scar ultrasound, colorimeter for pigmentation and erythema, and side effects. Results: After the treatment, most outcomes significantly improved except that the pigmentation of the scars did not change. Scar thickness significantly reduced by nearly 10% after the first IPL session, 15% after the second session, and>20% after the third session. All side effects were mild with crust (33.3-46%), blisters (8.3-40%), and hyperpigmentation around the scar (0-14%); the pain was moderate as assessed by the patients. Conclusion: IPL is a safe and effective treatment for keloids and hypertrophic scars. More studies are required to confirm our results.

Abstract
Traumatic scar is a disease that affected approximately tens of millions of patients worldwide. According to the histological and morphological properties of scars, the traumatic scar typically includes superficial scar, atrophic scar, hypertrophic scar, and keloid. Its formation is a natural consequence of wound healing, regardless of whether the wound was caused by trauma or surgery. However, the production of scars has considerable impacts on the physical and mental health of patients, even causing substantial aesthetic and functional impairments. Prevention or early treatment of scars is the most suitable therapeutic method, including surgical and non-surgical procedures; nevertheless, the benefits of non-operative therapies for scars are quite limited, and surgical treatments are always hard to achieve satisfying outcomes. Through the application of innovative technologies such as lasers, intense pulsed light, and radiofrequency, significant progress has been made in the treatment of traumatic scars. This review highlights the current advancements of photoelectric therapy for the prevention and treatment of various traumatic scars, which may throw light on innovative therapeutic options for scar therapies.

Abstract
Background and Objectives: Hair removal is a common aesthetic concern for patients referred to dermatologists and aesthetic physicians. Lasers and lights are one of the mainstays in the management of this condition. Among these devices, intense pulsed lights (IPLs) are broadly used in order to reduce the number and width of the hair present. Currently used techniques are associated with a high risk of side effects, such as hyper or hypopigmentation. Materials and Methods: Thirty patients seeking hair removal in one or more body areas with skin phototypes 1 to 4 were recruited to perform this study. All areas to be treated were divided into two equal regions; one side was treated with the standard IPL hair removal procedure, while the other was treated with a new “in-motion” IPL technology. Results and hair removal rates were evaluated six months after the last treatment. Results: Out of the 30 patients treated, all patients experienced hair reduction. No statistically significant difference in hair removal was noted among the two sides. A statistically significant reduction in pain during the procedure was observed in the side treated with the “in-motion” technique. Conclusions: Traditional and “in-motion” IPL techniques have similar results in hair removal; the “in-motion” technology seems to guarantee a better safety profile than the traditional technique, as well as maintains the same results over time and a faster treatment time. A more extensive clinical study will be necessary to confirm our study’s results.

Abstract
Objective: To evaluate relevant clinical outcomes and conclude possible mechanisms of intense pulsed light (IPL) in eyelid inflammation. Background: IPL devices were primarily applied in cutaneous vascular malformations and have been used in ocular diseases for about 20 years, mostly including meibomian gland dysfunction (MGD), blepharitis, and ocular rosacea. Recent findings: Seventy-two original clinical researches were included, 57 for MGD, 4 for blepharitis or blepharitis-related keratoconjunctivitis, and 11 for rosacea. Dry eye symptoms, (tear) break-up time (BUT), and meibomian structure and/or functions were improved in most patients, but production of reactive oxygen species is an important link in the photobiomodulation mediated by IPL, which can influence numerous signal pathways to achieve anti-inflammatory, anti-infective, and prodifferentiation effects. Conclusions: The evidence suggests that IPL is an effective therapeutic tool for most patients with MGD, but more clinical evidence is needed for other indications.

Abstract
BACKGROUND Aging is part of the immutable characteristics of the human being, and the search for treatments to alleviate the undesirable effects of aging is frequent in the dermatological office. AIMS This work proposes the technique of association of PDO threads with technologies and the description of the facial treatment protocols. METHODS For contextualization, two case studies of two patients subjected to the procedure are analyzed. CONCLUSIONS In recent years, there have been marked changes in facial rejuvenation techniques using PDO threads and these have shown satisfactory results for collagen biostimulation. Having technologies in dermatological clinics is a frequent reality, and sometimes, some doctors are in doubt about when to use them associated with PDO wires and in which sequence it should be done, ensuring patient safety and maintaining the integrity of the wires. This article aims to bring clarity about how to use technology and when is the right time. It is also intended to clarify that the PDO wire can be used in conjunction with the microfocused ultrasound technology, since the melting point of the PDO polymer is between 110° and 115°C.

Abstract
OBJECTIVE To investigate the efficacy and safety of broadband light (BBL) combined with intradermal injection of tranexamic acid for treating melasma. METHODS 120 women with melasma admitted to our hospital from January 2021 to April 2022 were randomly categorized into the following groups: control group, treated with 250 mg tranexamic acid given orally twice daily, except during menstruation; group I, treated with BBL (Sciton, Inc., USA) monthly; group II, received intradermal injections of tranexamic acid monthly; and group III, treated with BBL with intradermal injection of tranexamic acid monthly. Treatment in each group lasted three months. The MASI (Melasma Area Severity Index) and VISIA (Canfield VISIA Complexion Analysis) were used for evaluation. RESULTS After treatment course, MASI scores and VISIA brown spot and red zone ranking improved in all four groups (p < 0.05). The decrease in MASI scores and improvement rates of VISIA brown spot and red zone rankings were not significantly different among the control group, group I, and group II; however, the decreased MASI scores and improvement rates of VISIA brown spot and red zone rankings were significantly higher in group III than in the other three groups (p < 0.05). CONCLUSION The effect of BBL combined with the intradermal injection of TA in the treatment of melasma is remarkable. This combination therapy can be an alternative and effective treatment for managing melasma.

Abstract
It has been reported that about a quarter of the world's agriculture products is unable to be consumed each year because of mold contamination, resulting in incalculable economic losses. Despite modern food technology and the various preservation techniques available, the problem of mold contamination of food is still not adequately controlled. In this study, we simulated the biofilm formed by Aspergillus niger and Penicillium glaucum in liquid and solid food in 96 well cell culture plates and polycarbonate membrane models, respectively, and investigated the fungicidal effect of IPL on planktonic and biofilm molds at three different capacitance parameters at room and refrigerator temperatures. The results show that IPL can achieve fungicidal rates of over 99% for planktonic molds and over 90% for biofilm molds, and that the smaller the capacitance, the more frequent the irradiation required to achieve the same fungicidal rate. In addition, temperature, A. niger or Penicillium glaucum have no effect on the fungicidal effect of IPL. We believe that IPL is a promising non-thermal physical sterilization technique for fungal inhibition on food surfaces.

Abstract
Slightly more than half of the solar radiation that passes through the atmosphere and reaches the Earth's surface is infrared. Over the past few years, many papers have been published on the possible positive effects of receiving this part of the electromagnetic spectrum. In this article we analyse the role of mitochondria in the supposed effects of infrared light based on the published literature. It is claimed that ATP synthesis is stimulated, which has a positive effect on the skin by increasing fibroblast proliferation, anchorage and production of collagen fibres, procollagen, and various cytokines responsible for the wound healing process, such as keratinocyte growth factor. Currently there are infrared light emitting equipment whose manufacturers and the centres where this service or treatment is offered claim that they are used for skin rejuvenation among other positive effects. Based on the literature review, it is necessary to deepen the scientific study of the mechanism of absorption of infrared radiation through the skin to better understand its possible positive effects, the risks of overexposure and to improve consumer health protection.

Abstract
OBJECTIVES To evaluate the improvement in symptoms and signs associated with intense pulse light (IPL) combined with low-level light therapy (LLLT) in the treatment of dry eye disease (DED). METHODS A systematic review of full-length original studies reporting the effects of IPL combined with LLLT for DED in two databases, PubMed and Scopus, was performed according to the PRISMA statement. The quality assessment tool for case series studies from the National Heart, Lung, and Blood Institute was used to analyze the quality of the studies selected. RESULTS The search provided a total of 393 articles, of which six were included. Significant decreases in the Ocular Surface Disease Index (OSDI) score, meibomian gland dysfunction (MGD) score, MGD grade, and meiboscore and increases in tear film stability, lipid layer thickness, and loss area of the meibomian gland have been reported. Concerning tear volume, tear meniscus height, and Schirmer test remained unchanged. In relation to tear osmolarity and corneal fluorescein staining, contradictory outcomes were found. CONCLUSIONS Intense pulse light combined with LLLT for the treatment of dry eye improves OSDI, tear film stability, and meibomian gland function; thus, this treatment may be recommended for DED patients due to MGD.

Abstract
Although interest in recycling carbon fibers is rapidly growing, practical applications of recycled carbon fibers (rCFs) are limited owing to their poor wettability and adhesion. Surface modification of CFs was achieved through intense pulsed light (IPL) irradiation, which functionalizes surface of rCFs. Surface energy, chemical composition, morphology, and interfacial shear strength (IFSS) of rCFs before and after IPL irradiation were investigated. The rCF IPL-irradiated at 1,200 V improved both polar and dispersive components of surface energy, and the IFSS significantly increased by 2.93 times in relation to that of the pristine rCF and reached 95% of that of high-grade commercial CFs. We proposed a mechanism by which oxygen functional groups on the rCF surface enhance the molecular bonding force with HDPE, and the model was validated from molecular dynamics simulations. IPL irradiation is a rapid and effective surface treatment method that can be employed for the manufacture of rCF-reinforced composites. IPL irradiation was utilized for surface modification to control HDPE/rCF interfaces The IPL-irradiated rCF showed an increase in oxygen functional groups and roughness MD simulation revealed IFSS was enhanced by chemical interaction and interlocking Surface treatment using IPL energy facilitates commercialization of rCF composites

Abstract
BACKGROUND Acne patients frequently receive combination therapy. However, there has been no rigorous review of the efficacy of combining alpha hydroxy acid with IPL for acne vulgaris treatment. OBJECTIVE Assessing the effectiveness and safeness of alpha hydroxy acids in combination with IPL in the treatment of people with acne vulgaris. METHODS A computer search of common biomedical databases, including PubMed, Web of Science, Cochrane Library, Embase, Wanfang, CNKI, SinoMed, and VIP, was extensively conducted to identify previous studies on randomized controlled trials of alpha hydroxy acid combined with IPL in the management of acne vulgaris. RESULTS A total of 18 publications were included (1435 patients with common acne met the inclusion criteria). The meta-analysis showed that alpha hydroxy acid (AHA) combined with IPL had higher overall efficacy than the control group (OR = 4.24; 95% CI 2.66 ~ 6.74; p < 0.01). In the case of acne vulgaris, AHA combined with IPL and the AHA alone showed a remarkable difference in total efficiency (OR = 4.10; 95% CI 2.12 ~ 7.91; p < 0.01), and AHA combined with IPL were more effective than IPL alone (OR = 4.02; 95% CI 2.25 ~ 7.16; p < 0.01). In addition, the occurrence of adverse reactions that occurred in AHA combined with IPL and control groups did not differ (OR = 0.86; 95% CI 0.46 ~ 1.60; p = 0.64). CONCLUSION AHA combined with IPL therapy was superior to other therapies. Although it was slightly more expensive, it was effective and had a wide range of applications.

Abstract
To describe the efficacy and safety of intense pulsed light (IPL) applied directly on the eyelids of patients with Meibomian gland dysfunction (MGD) without corneal shield protector. Observational retrospective single centre study where patients underwent 3 treatment sessions of IPL with 2 weeks of interval. The IPL was carried out with Lumenis OPT M22 with a double pass technique of 12 impacts on the infraorbital/lower eyelid region with the 15 × 35 mm guide light (step 1) and a double pass technique of 3 impacts over the upper eyelids with the 8 × 15 mm guide light (step 2). The follow up was conducted through Oculus Keratograph 5 M. 30 patients were enrolled in the study. Although there were no significant differences (p > 0.05), non-invasive tear break-up time, ocular redness, and OSDI questionnaire improved during the 3 IPL sessions. A significant improvement (p = 0.024) in the percentage of meibomian gland loss was also observed. Regarding tear meniscus, it was found similar measurements before and after treatment. No serious adverse effects were reported during the procedure or in subsequent follow-up. Preliminary results suggest that IPL therapy applied directly on the eyelids without corneal shield could be safe and effective in the treatment of MGD.

Abstract
BACKGROUND Intense pulsed light (IPL) is a noninvasive therapeutic option to treat benign pigmented lesions by targeting melanin. OBJECTIVE The purpose of this study was to assess IPL as a treatment for benign pigmented dorsal hand lesions. MATERIALS AND METHODS A total of fifteen subjects, 40 to 73 years old, received 3 monthly IPL treatments over the dorsal hands. Subjects followed up 1 and 3 months after treatment. At every visit, photographs were taken using the VISIA Complexion Analysis System (Canfield Scientific, Fairfield, NJ) and analyzed using the RBX Brown Spots Analysis algorithm. The Clinician Global Aesthetic Improvement Scale and Subject Global Aesthetic Improvement Scale were completed at both follow-up visits. RESULTS A total of fifteen subjects completed all six visits. The number of brown spots decreased 9.26% ( p = .0004) and 7.52% ( p = .0132) at each follow-up visit. The mean brown intensity decreased 6.15% ( p = .0183) and 7.67% ( p = .0178), whereas the mean contrast intensity decreased 8.88% ( p < .0001) and 6.60% ( p = .0007) 1 and 3 months after treatment, respectively. The mean Clinician Global Aesthetic Improvement Scale was 2.03 and 2.23, whereas the mean Subject Global Aesthetic Improvement Scale 1 and 3 months after treatment was 1.6 and 1.8, respectively. CONCLUSION Objective analysis, along with clinician and subject assessments, showed an improvement in the appearance of benign pigmented lesions in the treated area after 3 IPL treatments.

Results of a twelve-Month, prospective, randomized split-face study. PHOTODERMATOLOGY, PHOTOIMMUNOLOGY & PHOTOMEDICINE 2022; 38:382-390. [PMID: 34989016 DOI: 10.1111/phpp.12765] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/05/2021] [Revised: 12/12/2021] [Accepted: 12/27/2021] [Indexed: 11/30/2022]
Abstract
BACKGROUND Despite the widespread use of intense pulsed light (IPL) technology in cosmetic dermatology, the effects of its repeated use on facial skin sensitivity in healthy individuals remains unknown. METHODS Seventeen healthy female volunteers were included in the study. We measured objective biophysical parameters of the skin, including transepidermal water loss (TEWL), skin glossiness, thickness and density of the epidermis and dermis, sensory nerve current perception threshold (CPT), and regional blood flow before and after treatment at different time points. RESULTS Sixteen volunteers completed a follow-up of 12 months. The treated side of the face showed a decreased TEWL on D1 and D3, which reverted to normal on D7. Epidermal thickness increased and skin glossiness decreased on the treated side on D1, but returned to normal on D3. We found no statistically significant differences in CPT values or in regional blood flow volume and velocity, with the exception of D1, which exhibited a higher regional blood flow volume on the treated side. CONCLUSION Repeated IPL treatments had no effects on facial skin barrier function, skin nerve sensitivity, or local microcirculation among healthy individuals. IPL is a safe skin care procedure that does not affect skin sensitivity.

Abstract
PURPOSE To compare the efficacy of intense pulsed light (IPL) and near-infrared light (NIL) treatments in alleviating symptoms and signs of dry eye disease (DED). METHODS Patients diagnosed with DED at the Peking University Third Hospital Eye Center from January 2019 to October 2019 were randomized to undergo either NIL therapy combined with meibomian gland expression (MGX; NIL Group) or IPL combined with MGX (IPL Group). Treatments were performed three times at 1-month intervals. DED signs and symptoms were evaluated before every treatment. We compared the clinical improvement within and between the groups. Additional comparisons were made according to the meibomian gland (MG) dropout grade. RESULTS A total of 260 eyes of 130 patients (mean age, 49.68 ± 18.01 years) were included. The dryness and total symptom scores and the MG expressibility and secretion quality (upper and lower eyelids) significantly improved after the three treatments in both groups (p < 0.05). However, IPL had superior efficacy in improving blurred vision, photophobia, burning, increased secretions and the total symptom score at 2 months in patients with more severe MG dropout. CONCLUSIONS Both IPL and NIL treatments were effective in the treatment of DED, but IPL provided greater symptom improvement, particularly in patients with severe MG dropout. NIL can be a new therapeutic option for the treatment of DED.

Abstract
BACKGROUND Telangiectasias (spider veins) and reticular veins on the lower limbs are very common, increase with age, and have been found in 41% of women. The cause is unknown and the patients may be asymptomatic or can report pain, burning or itching. Treatments include sclerotherapy, laser, intense pulsed light, microphlebectomy and thermoablation, but none is established as preferable. OBJECTIVES To assess the effects of sclerotherapy, laser therapy, intensive pulsed light, thermocoagulation, and microphlebectomy treatments for telangiectasias and reticular veins. SEARCH METHODS The Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE, Embase, AMED and CINAHL databases, and the World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov trials registers to 16 March 2021. We undertook additional searches in LILACS and IBECS databases, reference checking, and contacted specialists in the field, manufacturers and study authors to identify additional studies. SELECTION CRITERIA We included randomised controlled trials (RCTs) and quasi-RCTs that compared treatment methods such as sclerotherapy, laser therapy, intensive pulsed light, thermocoagulation, and microphlebectomy for telangiectasias and reticular veins in the lower limb. We included studies that compared individual treatment methods against placebo, or that compared different sclerosing agents, foam or laser treatment, or that used a combination of treatment methods. DATA COLLECTION AND ANALYSIS Three review authors independently performed study selection, extracted data, assessed risks of bias and assessed the certainty of evidence using GRADE. The outcomes of interest were resolution or improvement (or both) of telangiectasias, adverse events (including hyperpigmentation, matting), pain, recurrence, time to resolution, and quality of life. MAIN RESULTS We included 3632 participants from 35 RCTs. Studies compared a variety of sclerosing agents, laser treatment and compression. No studies investigated intensive pulsed light, thermocoagulation or microphlebectomy. None of the included studies assessed recurrence or time to resolution. Overall the risk of bias of the included studies was moderate. We downgraded the certainty of evidence to moderate or low because of clinical heterogeneity and imprecision due to the wide confidence intervals (CIs) and few participants for each comparison. Any sclerosing agent versus placebo There was moderate-certainty evidence that sclerosing agents showed more resolution or improvement of telangiectasias compared to placebo (standard mean difference (SMD) 3.08, 95% CI 2.68 to 3.48; 4 studies, 613 participants/procedures), and more frequent adverse events: hyperpigmentation (risk ratio (RR) 11.88, 95% CI 4.54 to 31.09; 3 studies, 528 participants/procedures); matting (RR 4.06, 95% CI 1.28 to 12.84; 3 studies, 528 participants/procedures). There may be more pain experienced in the sclerosing-agents group compared to placebo (SMD 0.70, 95% CI 0.06 to 1.34; 1 study, 40 participants; low-certainty evidence). Polidocanol versus any sclerosing agent There was no clear difference in resolution or improvement (or both) of telangiectasias (SMD 0.01, 95% CI -0.13 to 0.14; 7 studies, 852 participants/procedures), hyperpigmentation (RR 0.94, 95% CI 0.62 to 1.43; 6 studies, 819 participants/procedures), or matting (RR 0.82, 95% CI 0.52 to 1.27; 7 studies, 859 participants/procedures), but there were fewer cases of pain (SMD -0.26, 95% CI -0.44 to -0.08; 5 studies, 480 participants/procedures) in the polidocanol group. All moderate-certainty evidence. Sodium tetradecyl sulphate (STS) versus any sclerosing agent There was no clear difference in resolution or improvement (or both) of telangiectasias (SMD -0.07, 95% CI -0.25 to 0.11; 4 studies, 473 participants/procedures). There was more hyperpigmentation (RR 1.71, 95% CI 1.10 to 2.64; 4 studies, 478 participants/procedures), matting (RR 2.10, 95% CI 1.14 to 3.85; 2 studies, 323 participants/procedures) and probably more pain (RR 1.49, 95% CI 0.99 to 2.25; 4 studies, 409 participants/procedures). All moderate-certainty evidence. Foam versus any sclerosing agent There was no clear difference in resolution or improvement (or both) of telangiectasias (SMD 0.04, 95% CI -0.26 to 0.34; 2 studies, 187 participants/procedures); hyperpigmentation (RR 2.12, 95% CI 0.44 to 10.23; 2 studies, 187 participants/procedures) or pain (SMD -0.10, 95% CI -0.44 to 0.24; 1 study, 147 participants/procedures). There may be more matting using foam (RR 6.12, 95% CI 1.04 to 35.98; 2 studies, 187 participants/procedures). All low-certainty evidence. Laser versus any sclerosing agent There was no clear difference in resolution or improvement (or both) of telangiectasias (SMD -0.09, 95% CI -0.25 to 0.07; 5 studies, 593 participants/procedures), or matting (RR 1.00, 95% CI 0.46 to 2.19; 2 studies, 162 participants/procedures), and maybe less hyperpigmentation (RR 0.57, 95% CI 0.40 to 0.80; 4 studies, 262 participants/procedures) in the laser group. All moderate-certainty evidence. High heterogeneity of the studies reporting on pain prevented pooling, and results were inconsistent (low-certainty evidence). Laser plus sclerotherapy (polidocanol) versus sclerotherapy (polidocanol) Low-certainty evidence suggests there may be more resolution or improvement (or both) of telangiectasias in the combined group (SMD 5.68, 95% CI 5.14 to 6.23; 2 studies, 710 participants), and no clear difference in hyperpigmentation (RR 0.83, 95% CI 0.35 to 1.99; 2 studies, 656 participants) or matting (RR 0.83, 95% CI 0.21 to 3.28; 2 studies, 656 participants). There may be more pain in the combined group (RR 2.44, 95% CI 1.69 to 3.55; 1 study, 596 participants; low-certainty evidence). AUTHORS' CONCLUSIONS Small numbers of studies and participants in each comparison limited our confidence in the evidence. Sclerosing agents were more effective than placebo for resolution or improvement of telangiectasias but also caused more adverse events (moderate-certainty evidence), and may result in more pain (low-certainty evidence). There was no evidence of a benefit in resolution or improvement for any sclerosant compared to another or to laser. There may be more resolution or improvement of telangiectasias in the combined laser and polidocanol group compared to polidocanol alone (low-certainty evidence). There may be differences between treatments in adverse events and pain. Compared to other sclerosing agents polidocanol probably causes less pain; STS resulted in more hyperpigmentation, matting and probably pain; foam may cause more matting (low-certainty evidence); laser treatment may result in less hyperpigmentation (moderate-certainty evidence). Further well-designed studies are required to provide evidence for other available treatments and important outcomes (such as recurrence, time to resolution and delayed adverse events); and to improve our confidence in the identified comparisons.

Abstract
Aged skin is characterized by appearance of wrinkles, vascular lesions, hyperpigmentation, lentignes, texture, rhytides, and pores. These changes occur under the influence of intrinsic and extrinsic factors, as hormone alterations and exposure to ultraviolet light (UV) irradiation, respectively. Skin changes associated with aging have been assuming an important role in nowadays and bring to affect the quality of life. Intense Pulsed Light (ILP) is a noncollimated, polychromatic, and noncoherent non-surgical cosmetic therapy to skin rejuvenation. This is the first systematic review evaluating ILP treatment on skin rejuvenation evaluated by digital photographs and self-reported treatment efficacy. A PRISMA compliant review includes a search of the databases Scopus and PubMed. Sixteen studies treating 637 participants (with Fitzpatrick skin types I to IV and age varying from 21 to 80 years) were included. Patients were treated a mean of 4.29 sessions (range 3-7). The most studies results showed the efficacy of IPL treatment in telangiectasia, wrinkles, pore, erythema, rhytids, texture, lentigines, hiperpigmentation, and photoaging score. Six studies showed IPL-positive effects in association with other treatment and seven studies showed superior effect of other treatment or association to IPL with other treatment related to IPL alone. Nine studies showed low methodological quality. In conclusion, ILP treatment is effective on skin rejuvenation. However, there is no consensus about the parameters and future studies are needed to sample size limitations, made RCTs with low risk of bias, and improve the methodological quality its.

Tear film interferometry assessment after intense pulsed light in dry eye disease: A randomized, single masked, sham-controlled study. Cont Lens Anterior Eye 2021; 45:101499. [PMID: 34433517 DOI: 10.1016/j.clae.2021.101499] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2021] [Revised: 08/05/2021] [Accepted: 08/05/2021] [Indexed: 01/11/2023]
Abstract
BACKGROUND Inadequate meibomian glands (MGs) secretion can lead to dry eye signs and symptoms. Tear film lipid layer (TFLL) secreted by MGs protects and prevents rapid evaporation of tear film. The purpose was to assess TFLL alteration and function in patients with evaporative dry eye (EDE) using tear interferometry after optimal pulse light technology (OPT) intense pulsed light (IPL). METHODS This prospective randomized examiner-masked sham- controlled study included 86 participants (142 eyes) with DED. IPL or sham procedure was performed on day 0, 21, and 42. Ocular Surface Disease Index (OSDI), non-invasive breakup time (NITBUT), interferometric fringe pattern determined TFLL quality, fluorescein staining (FS), and meibum gland (MG) were assessed at day 0, 21, 42 and 3-month. RESULTS At 3-month, TFLL, NITBUT, MG drop-out, MG quality, MG expressibility, FS and OSDI improved significantly (P < 0.05) in the IPL group, while the sham group had no significant improvements. Except for Meibo-score and FS, all parameters significantly correlated with the improvement in TFLL following IPL treatment. Additionally, artificial tears usage was significantly less in the IPL group from D-42 onwards. CONCLUSION IPL treatment demonstrated the ability to improve TFLL quality and clinically reduced sign and symptoms of DED thereby reducing the frequency of artificial tears use.

Abstract
In recent years, traditional high-temperature food processing is continuously being replaced by nonthermal processes. Nonthermal processes have a positive effect on food quality, including color and maintaining natural food pigments. Thus, this article describes the influence of nonthermal, new, and traditional treatments on natural food pigments and color changes in plant materials. Characteristics of natural pigments, such as anthocyanins, betalains, carotenoids, chlorophylls, and so forth available in the plant tissue, are shortly presented. Also, the characteristics and mechanism of nonthermal processes such as pulsed electric field, ultrasound, high hydrostatic pressure, pulsed light, cold plasma, supercritical fluid extraction, and lactic acid fermentation are described. Furthermore, the disadvantages of these processes are mentioned. Each treatment is evaluated in terms of its effects on all types of natural food pigments, and the possible applications are discussed. Analysis of the latest literature showed that the use of nonthermal technologies resulted in better preservation of pigments contained in the plant tissue and improved yield of extraction. However, it is important to select the appropriate processing parameters and to optimize this process in relation to a specific type of raw material.

Lasers Surg Med 2021; 53:1348-1355. [PMID: 34224604 DOI: 10.1002/lsm.23426] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2020] [Revised: 05/06/2021] [Accepted: 05/14/2021] [Indexed: 11/07/2022]
Abstract
BACKGROUND AND OBJECTIVES The skin microbiota partly determined by epidermal barrier plays an important role in acne vulgaris and intense pulsed light (IPL) has been verified as a safe and effective therapeutic option for this disease. Nevertheless, the exact role of the IPL treatment on the skin microbiota and epidermal barrier for patients with acne vulgaris remains unclear. This article was designed to solve this problem. STUDY DESIGN/MATERIALS AND METHODS Nineteen healthy controls and 20 patients with mild to moderate acne were enrolled in this study, who received IPL treatment for 12 weeks. The epidermal barrier and skin samples were collected at baseline and after treatment. The microbial diversity was analyzed based on a high-throughput sequencing approach, which targets the V3-V4 region of the bacteria 16S ribosomal RNA genes. RESULTS After treatment of IPL, the Global Acne Grading System (GAGS) scores, sebum, sclererythrin, and red area of patients were significantly improved by IPL treatment (P < 0.05). Although there was no difference in microbiota diversity before and after IPL treatment, the Nonmetric Multidimension Scaling (NMDS) analysis showed that the samples of the acne patients before and after treatment could be divided into two different sets by skin microbiota (P = 0.011), which could be verified by heatmap analysis. Moreover, we found that the relative abundance of Staphylococcus epidermidis (S. epidermidis) significantly increased, but Cutibacterium acnes (C. acnes) decreased after IPL treatment. The sebum concentration was positively correlated with PH value (R = 0.525, P = 0.017), and the GAGS was positively associated with both sclererythrin (R = 0.477, P = 0.002) and red area (R = -0.503, P = 0.001). CONCLUSIONS IPL could successfully improve the GAGS scores of acne vulgaris, as well as regulate the equilibrium between C. acnes and S. epidermidis, and inhibit the sebum secretion. Lasers Surg.

Abstract
The increasing prevalence of laser use, particularly in plastic surgery, demands education of both practitioners and trainees to ensure efficacy and patient safety. The purpose of this continuing medical education module is to provide the learner with a detailed outline for laser training education for plastic surgery trainees. In this overview, a discussion of the characteristics of light, an introduction to fundamental laser principles, a comparison of lasers and pulsed light systems, and examples of several therapeutic applications for light-based devices in the clinical setting will be presented. Additionally, the 5 parameters necessary for operation of light-based devices, as well as the importance of laser safety education, will be reviewed. We hope this continuing medical education will provide both practicing plastic surgeons and trainees with the proper education on the lasers and pulsed light devices they will use in their clinical practices.

Abstract
Skin aging may be divided into intrinsic and extrinsic aging or photoaging. The first is a natural, slow and gradual process. The second is exacerbated by environmental factors such as improper exposure to sunlight. There are a myriad of therapeutic modalities that can improve photoaging. Intense pulsed light, radiofrequency and carboxytherapy are good procedural modalities to improve skin aging. This study aimed to evaluate and compare the efficacy and safety of IPL, RF, and carboxytherapy in facial rejuvenation. This study included 60 patients with facial wrinkles. Patients were divided into three groups. Group 1 was treated with IPL, group 2 was treated with radiofrequency while group 3 was treated with carboxytherapy. All patients received four sessions with 3-4 week interval and followed up after 3 months after the end of treatment. Patients were assessed by digital photographing and skin biopsies before and after treatment. There was a significant difference in the percentage of improvement and patients' satisfaction with more significance in group 1, followed by group 3 then group 2. IPL was the more effective, followed by carboxytherapy then RF at the end in facial rejuvenation. These results were confirmed by immunohistochemical expression of MMP1.

Abstract
The skin of an organism is affected by various environmental factors and fights against aging stress via mechanical and biochemical responses. Photoaging induced by ultraviolet B (UVB) irradiation is common and is the most vital factor in the senescence phenotype of skin, and so, suppression of UVB stress-induced damage is critical. To lessen the UVB-induced hyperimmune response and hyperpigmentation, we investigated the ameliorative effects of intense pulsed light (IPL) treatment on the photoaged phenotype of skin cells. Normal human epidermal keratinocytes and human epidermal melanocytes were exposed to 20 mJ/cm2 of UVB. After UVB irradiation, the cells were treated with green (525–530 nm) and yellow (585–592 nm) IPL at various time points prior to the harvest step. Subsequently, various signs of excessive immune response, including expression of proinflammatory and melanogenic genes and proteins, cellular oxidative stress level, and antioxidative enzyme activity, were examined. We found that IPL treatment reduced excessive cutaneous immune reactions by suppressing UVB-induced proinflammatory cytokine expression. IPL treatment prevented hyperpigmentation, and combined treatment with green and yellow IPL synergistically attenuated both processes. IPL treatment may exert protective effects against UVB injury in skin cells by attenuating inflammatory cytokine and melanogenic gene overexpression, possibly by reducing intracellular oxidative stress. IPL treatment also preserves antioxidative enzyme activity under UVB irradiation. This study suggests that IPL treatment is a useful strategy against photoaging, and provides evidence supporting clinical approaches with non-invasive light therapy.

Abstract
BACKGROUND Different therapeutic modalities have been tried for hypertrophic scar treatment. To our knowledge, intense pulsed light (IPL) has not been previously evaluated in comparison with cryotherapy as a stand-alone treatment for hypertrophic scars. OBJECTIVE We aimed to evaluate the efficacy of IPL as a monotherapy for hypertrophic scar treatment as compared with cryotherapy both clinically and histopathologically. METHODS This study included 28 patients with hypertrophic scars. Patients were divided randomly and equally into two groups; group I patients received cryotherapy while group II patients received IPL. All patients received treatments for a total of six sessions or until resolution of the lesion whichever was nearer. The outcome was evaluated clinically and histopathologically. RESULTS Scar height showed a significant decrease and scar color and pliability showed a significant improvement in group I. No significant changes were detected in group II except in scar pliability. Vancouver scar scale (VSS) mean decreased by -53.7% in group I versus -11.5% decrease in group II. Histopathologically, group I showed a significantly increased epidermal thickness and decreased dermal and collagen bundle thickness, while group II showed insignificant histopathological changes. Group I exhibited a statistically significant clinical and histopathological improvement compared to group II, yet with more complications. CONCLUSION Cryotherapy is more effective than IPL in the treatment of hypertrophic scars both on clinical and histopathological level yet with more complications.

Abstract
Unlike other rosacea therapies which need daily takings or applications over long periods, the edge of lasers and light-based therapies (LLBT) is the limited number of sessions to achieve improvement. The proper selection of the adequate physical device in accordance with the patients' skin features and rosacea-related signs and symptoms should be considered and the management with physical sources should be updated as new data become available. This article reviews and discusses the current use of lasers and light-based therapies in rosacea with reference to all the available literature.This systematic review demonstrates the quality of evidence to support any recommendation on LLBT in rosacea is low-to-moderate. Among all the available devices, PDL holds the most robust evidence. Treatments options should be tailored for each specific clinical scenario as it is unlike that single modality results in complete resolution. Platforms that include two or more devices and combined therapies with topical agents are suitable and they warrant further investigations.

Abstract
BACKGROUND Freckles are typical epidermal pigmented disorders that occur at sun-exposed areas, presenting with dark-brown or light-brown circular hyperpigmentation. A lot of treatment modalities have been used for treatment of freckles like chemicals, electrosurgery and cryotherapy. These treatments may cause undesirable side effects such as scaring (Sarkar et al. in Indian J Dermatol 62(6):578-584, 2017). Microdermabrasion has been used in treatment of freckles; however, the results are not satisfactory, as it removes the outermost layer of the epidermis only (El-Domyati et al. in J Cosmet Dermatol 15(4):503-513, 2016). Also ablative lasers and non-ablative lasers have been used but have not proved to be completely satisfactory and share a common risk of post-inflammatory hyperpigmentation (Jang et al. in Dermatol Surg 26:231-234, 2000). In our study, we have used epiderm-abrasion-assisted intensive pulsed light (IPL) and radiofrequency (RF) to study their effect in treatment of freckles. PATIENTS AND METHODS this prospective controlled clinical trial was carried out on 48 patients, who presented with extensive facial freckles, in the period between March 2015 and April 2018. The epiderm-abrasion procedure was performed first, and then, electro-photobiomodulation sessions were started two weeks later. RESULTS This study was carried out on 48 patients, 39 female and 9 males. Their age ranged between 12 and 58 years old. According to Fitzpatrick classification, four patients were type II, 30 patients were type III, and 14 patients were type IV. The results were excellent in 32 cases, good in 12 cases, fair in four cases, and we have no poor results. Side effects like hyperpigmentation were reported in three patients (6.3%), one case grade III and two cases grade IV Fitzpatrick skin type. No cases with hypopigmentation, or scars, were reported. CONCLUSIONS Epiderm-abrasion and electro-photobiomodulation (IPL&RF) are effective methods in treatment of facial freckles. Some complications may occur post-procedure such as hyperpigmentation, hypopigmentation and abnormal scarring.

Abstract
BACKGROUND AND OBJECTIVE To analyze the occurrence and causes of adverse events (AEs) in intense pulsed light (IPL) combined with meibomian gland expression (MGX) and MGX treatment alone for meibomian gland dysfunction (MGD). STUDY DESIGN/MATERIALS AND METHODS A retrospective study was conducted on MGD patients treated in Wuhan Aier Hankou Eye Hospital from February 2018 to October 2019 to compare the AEs between IPL-MGX and MGX groups. Relevant AEs that occurred during the treatment and within 1 month after the patients' last treatment were recorded and the causes of the AEs were analyzed. RESULTS A total of 2,282 patients received IPL-MGX and 1,407 received MGX treatment. No serious AEs occurred in both groups. There were 74 AEs in the IPL-MGX group, with an incidence of 3.24%, including 14 significant AEs (2 cases of epidemic keratoconjunctivitis, 1 recurrent herpes simplex keratitis (HSK), 9 new onsets of floaters, 1 recurrent glaucomatocyclitic crises, and 1 recurrent iridocyclitis). There were 27 AEs in the MGX group with a rate of 1.92%, including 4 significant AEs (2 cases of keratoconjunctivitis epidemic, 2 new cases of floaters). Compared with the IPL-MGX group, the incidence of AEs in the MGX group was lower (P = 0.017). CONCLUSIONS Both IPL-MGX and MGX treatment are safe therapies with low risk for AEs. IPL treatment is not recommended for young children (age 10 or less) as well as patients with anterior uveitis or glaucomatocyclitic crises. The previous history of HSK and eyes with high myopia are advised to exercise caution in IPL treatment. Lasers Surg. Med. © 2020 Wiley Periodicals LLC.

Abstract
BACKGROUND Becker's nevus is a common skin disorder. Lasers and light instruments are the major modalities for the treatment of Becker's nevus, but the outcomes were mixed. OBJECTIVE To evaluate the efficacy of the intense pulsed light for Becker's nevus in a large Chinese cohort. METHODS We retrospectively analyzed the efficacy of the intense pulsed light for Becker's nevus in a single center. RESULTS A total of 45 patients, including 26 males and 19 females (male to female ratio = 1.4), aged 5-42 years, were included in this analysis. Twenty-seven patients (60%) were with hypertrichosis. Treatments with intense pulsed light resulted in over 75% improvements in pigmentation and hair density in 1 and 2 cases, respectively. One patient displayed 51%-75% reductions in hair density. The rest displayed ≤50% improvements in pigmentation and hair density. Recurrence occurred in all cases within 6 months after the last treatment. Adverse reactions were temporary and mild hypopigmentation, hyperpigmentation, hypertrophic scar, pain, and erythema. CONCLUSION Intense pulsed light does not exhibit long-term benefits for Becker's nevus. Further studies in the large cohort are still required to validate the present results. Moreover, whether changes in the treatment parameters can improve the efficacy of intense pulsed light remains to be explored.

Abstract
Meibomian gland dysfunction (MGD) is frequently encountered by eye care practitioners. It is characterised by obstruction of the Meibomian glands and/or alterations in the consistency of glandular secretions. At present, no definitive treatment exists for this condition. The present meta-analysis was performed to assess the efficacy of intense pulsed light (IPL) therapy in the management of MGD. Databases including EMBASE, PubMed, Cochrane Central, MEDLINE and Google Scholar were systematically searched to identify clinical trials that assessed the efficacy of IPL in the treatment of MGD. Outcome measures were described as the standardized mean difference (SMD). The fixed- or random-effects model was selected for analysis based on the Cochrane I2 values representing heterogeneity. Publication bias was visually inspected using Begg's funnel plot. Data were synthesized from four randomized controlled trials (RCTs) comprising 122 subjects in the IPL group and 120 subjects in the control group. Pooled analysis indicated no statistically significant difference in the Standard Patient Evaluation of Eye Dryness (SPEED) scores between the two groups [SMD -0.16 (95% CI, -0.41 to 0.10)] but a significant increase in Non-Invasive Tear Break-Up Time (NIBUT) scores in the IPL group (SMD, 0.90; 95% CI, 0.40-1.40). To conclude, the results of the present study did not provide any conclusive evidence for the efficacy of IPL therapy in the management of MGD. The analysis indicated that IPL therapy may result in an improvement of objective NIBUT scores but has no effect on subjective SPEED scores. Given the limited number of studies performed to date, there is a requirement for more well-designed prospective RCTs with a larger sample size to provide further evidence on the efficacy of IPL therapy.

Abstract
Treatment of cutaneous leishmaniasis (CL) continues to be a health concern, and alternative therapies with fewer side effects are substantially needed. This study aimed to determine the efficacy of intense pulsed light (IPL) with wavelength spectrum affecting vascular lesions on acute cutaneous leishmaniasis. In this randomized clinical trial study, 30 patients with acute CL were enrolled. Baseline clinical and demographic data were recorded in the checklist after obtaining written informed consent. Patients were randomly allocated to receive either IPL fortnightly (intervention group) or intralesional meglumine antimoniate (MA) weekly (control group) over 10 weeks. Patients were assessed every 2 weeks to determine the size of induration and improvement rate of lesions. Follow-up visits were arranged at 3rd and 6th months. Overall, 15 patients (21 lesions) in the intervention group and 15 patients (22 lesions) in the control group were studied. The size of lesions in the control group was significantly higher at the baseline (P = 0.014) and the second week (P = 0.034), and significantly lower in the eighth week (P = 0.009), compared with the intervention group. The size of lesions in the control group changed during the study (P < 0.001), whereas changes were not significant in the intervention group. The trend of changes in size of lesions was faster in the control group (P < 0.001). More patients in the control group had higher improvement rate at the sixth (P = 0.005) and tenth (P < 0.001) weeks. At the end of study, the cure rate was 35% (7 out of 20 lesions) in intervention group and 81.8% (18 out of 22 lesions) in the control group. Complete response happened earlier in the control group (P < 0.001). None of the lesions that were cured before the tenth week relapsed after 6 months. The frequency of blistering was significantly higher in intervention group (P = 0.001). Our results indicated that IPL with wavelength spectrum affecting vascular lesions was inferior to intralesional MA in treatment of CL. However, it can be considered as a second-line option, especially in patients with limitations for use of MA. Trial registry: https://www.irct.ir/trial/34246 IRCT20140414017271N5.

Pulsed light is an emerging non-thermal technology viable for foodstuff sanitation. The sanitation is produced through the use of high energy pulses during ultra-short periods of time (ns to µs). The pulsed light induces irreversible damages at the DNA level with the formation of pyrimidine dimers, but also produces photo-thermal and photo-physical effects on the microbial membranes that lead to a reduction in the microbial populations. The reduction caused in the microbial populations can reach several fold, up to 4 log CFU/mL decrement. A slight increase of 3 to 4 °C in temperature is observed in treated food; nonetheless, this increase does not modify either the nutritional properties of the product or its sensory profile. The advantages of using pulsed light could be used to a greater extent in the winemaking industry. Experimental trials have shown a positive effect of reducing native yeast and bacteria in grapes to populations below 1–2 log CFU/mL. In this way, pulsed light, a non-thermal technology currently available for the sanitation of foodstuffs, is an alternative for the reduction in native microbiota and the later control of the fermentative process in winemaking. This certainly would allow the use of fermentation biotechnologies such as the use of non-Saccharomyces yeasts in mixed and sequential fermentations to preserve freshness in wines through the production of aroma volatile compounds and organic acids, and the production of wines with less utilization of SO2 in accordance with the consumers’ demand in the market.

Intense pulsed light treatment in meibomian gland dysfunction: A concise review. Ocul Surf 2020; 18:583-594. [PMID: 32629039 DOI: 10.1016/j.jtos.2020.06.002] [Citation(s) in RCA: 36] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2020] [Revised: 05/18/2020] [Accepted: 06/04/2020] [Indexed: 12/23/2022]
Abstract
PURPOSE To review the published literature related to application of intense pulsed light (IPL) for treating meibomian gland dysfunction (MGD). METHODS The literature search included the PubMed database and used the keywords "Intense Pulsed Light and Meibomian Gland Dysfunction". RESULTS IPL is a new instrumental treatment modality for MGD. This treatment modality was originally developed for use in dermatology and was later adopted in ophthalmology for treating MGD. IPL therapy for MGD can improve tear film stability, meibomian gland functionality, as well as subjective feeling of ocular dryness. However, in the reviewed literature, there was great variability in patient selection, evaluation criteria, and treatment protocols and durations. CONCLUSION Numerous studies report that IPL is effective for treating MGD and a safe procedure. There is great potential for further improvements to the procedure, as large comparative studies employing different treatment modalities are lacking.
