PLoS One 2024; 19:e0304605. [PMID: 38861499 PMCID: PMC11166340 DOI: 10.1371/journal.pone.0304605] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2024] [Accepted: 05/14/2024] [Indexed: 06/13/2024] Open
Abstract
Canine Alopecia X is a non-inflammatory hair loss disorder of unknown etiology that predominantly affects German Spitz dogs. Treatment modalities include hormone and/or melatonin supplementation and low trauma microneedling. Melatonin influences hair growth and pigmentation in several species and presents a low risk of adverse effects when used in dogs with Alopecia X. Photobiomodulation (PBM) is frequently used in human androgenetic alopecia and alopecia areata; despite this, PBM remains unexplored in canine Alopecia X. To address this knowledge gap, sixty dogs of both sexes will be randomly assigned to three groups: (i) melatonin only group (3 mg/Kg, n = 20); (ii) PBM only group (diode laser, wavelength 660nm, 100mw power, with 3 J/point, 2 sessions/week for 3 months, n = 20); (ii) PBM + melatonin group (n = 20). The objective is to determine the potential of PBM alone or in conjunction with melatonin supplementation in promoting hair regrowth (hair density and diameter) by means of dermatoscopy and planimetry over a period of 90 days.

Abstract
Background: A systematic review on low-level light/laser therapy (LLLT) in male pattern hair loss (MPHL) and female pattern hair loss (FPHL) has been performed. Objectives: Compare the reported effectiveness of LLLT in MPHL and FPHL with any control, through randomized controlled trials (RCTs) analysis. Methods: The protocol was developed in accordance with the Preferred Reporting for Items for Systematic Reviews and Meta-Analyses-Protocols guidelines. A multistep search of the PubMed, MEDLINE, Embase, PreMEDLINE, Ebase, Clinicaltrials.gov, Scopus database, and Cochrane databases has been performed to identify articles on MPHL and/or FPHL treatment with LLLT. Results: Of the 298 articles initially identified, 136 articles focusing on MPHL and FPHL were selected and, consequently, only 36 articles focused exclusively on LLLT. Of this amount, 23 articles were clinical trials while 13 articles were systematic reviews. Systematic reviews were excluded, and only seven articles were analyzed as RCTs. Conclusions: All the articles selected and analyzed reported a positive effect of LLLT for MPHL and/or FPHL treatment without side effects.

Abstract
Photobiomodulation is a treatment option for hair loss and is currently FDA cleared for androgenetic alopecia. There are a variety of photobiomodulation devices intended for at-home patient use. However, data examining user preferences is lacking. A social media-based, online survey study was completed to understand patient preferences when selecting a photobiomodulation device. Secondary outcomes examined patient experience with the device. Sixty participants responded to the 21-question survey. The majority of participants had never used a photobiomodulation device (n = 50; 86.2%). Most respondents (n = 40; 67.8%) felt the efficacy of the device was the most important aspect to consider when selecting a photobiomodulation device. Additionally, a majority of participants thought 15 (n = 22; 37.3%) or 20 minutes (n = 17; 28.8%) would be a reasonable treatment duration and would prefer a hand-free device (n = 51; 86.4%). Of the eight participants who had used a photobiomodulation device, only one was dissatisfied with the device and discontinued treatment.

Abstract
The hair follicle (HF) is a multicellular complex structure of the skin that contains a reservoir of multipotent stem cells. Traditional hair repair methods such as drug therapies, hair transplantation, and stem cell therapy have limitations. Advances in nanotechnology offer new approaches for HF regeneration, including controlled drug release and HF-specific targeting. Until recently, embryogenesis was thought to be the only mechanism for forming hair follicles. However, in recent years, the phenomenon of wound-induced hair neogenesis (WIHN) or de novo HF regeneration has gained attention as it can occur under certain conditions in wound beds. This review covers HF-specific targeting strategies, with particular emphasis on currently used nanotechnology-based strategies for both hair loss-related diseases and HF regeneration. HF regeneration is discussed in several modalities: modulation of the hair cycle, stimulation of progenitor cells and signaling pathways, tissue engineering, WIHN, and gene therapy. The HF has been identified as an ideal target for nanotechnology-based strategies for hair regeneration. However, some regulatory challenges may delay the development of HF regeneration nanotechnology based-strategies, which will be lastly discussed.

Abstract
BACKGROUND Infrared radiation (IR) is the portion of the electromagnetic spectrum between visible light (VL) and microwaves, with wavelengths between 700 nm and 1 mm. Humans are mainly exposed to ultraviolet (UV) radiation (UVR) and IR through the sun. Unlike UVR which is well known for its carcinogenic properties, the relationship between IR and skin health has not been as extensively studied; as such, we gather the available published evidence here to better elucidate this relationship. METHODS Several databases including Pubmed, Google Scholar, and Embase were searched for articles relating to infrared radiation and the skin. Articles were selected for their relevance and novelty. RESULTS Detrimental effects such as thermal burns, photocarcinogenesis, and photoaging have been reported, though evidence suggests that these may be due to the thermal effects produced secondary to IR exposure rather than the isolated effect of IR. There are currently no chemical or physical filters specifically available for protection against IR, and existing compounds are not known to have IR-filtering capacity. Interestingly, IR may have some photoprotective properties against the carcinogenic effects of UVR. Furthermore, IR has been used with encouraging results in skin rejuvenation, wound healing, and hair restoration when given at an appropriate therapeutic dose. CONCLUSION A better understanding of the current landscape of research surrounding IR can help illuminate its effects on the skin and highlight areas for further research. Here, we review relevant data on IR to assess its deleterious and beneficial effects on human skin, along with possible means for IR photoprotection.

Abstract
Malocclusion is one of the three major diseases, the incidence of which could reach 56% of the imperiled oral and systemic health in the world today. Orthodontics is still the primary method to solve the problem. However, it is clear that many orthodontic complications are associated with courses of long-term therapy. Photobiomodulation (PBM) therapy could be used as a popular way to shorten the course of orthodontic treatment by nearly 26% to 40%. In this review, the efficacy in cells and animals, mechanisms, relevant cytokines and signaling, clinical trials and applications, and the future developments of PBM therapy in orthodontics were evaluated to demonstrate its validity. Simultaneously, based on orthodontic mechanisms and present findings, the mechanisms of acceleration of orthodontic tooth movement (OTM) caused by PBM therapy were explored in relation to four aspects, including blood vessels, inflammatory response, collagen and fibers, and mineralized tissues. Also, the cooperative effects and clinical translation of PBM therapy in orthodontics have been explored in a growing numbers of studies. Up to now, PBM therapy has been gaining popularity for its non-invasive nature, easy operation, and painless procedures. However, the validity and exact mechanism of PBM therapy as an adjuvant treatment in orthodontics have not been fully elucidated. Therefore, this review summarizes the efficacy of PBM therapy on the acceleration of OTM comprehensively from various aspects and was designed to provide an evidence-based platform for the research and development of light-related orthodontic tooth movement acceleration devices.

Abstract
Introduction: Alopecia areata (AA) is an autoimmune, inflammatory, non-scarring hair loss in which T-cells target hair follicles. Given that the available therapeutic options generally do not induce and sustain remission of AA effectively and many adverse effects may occur, monochromatic light sources have been recently gaining attention from clinicians. Therefore, the present paper aimed to report the first case in which photobiomodulation therapy (PBMT) with a continuous wave red laser (660 nm) was used as monotherapy for AA. Case Presentation: An isolated round area of complete hair loss was subjected to daily PBMT sessions, resulting in significant regrowth (hair of normal coloration and thickness) within 7 days. On the 21st day, the patient's aesthetic concern was completely resolved. Conclusion: PBMT with a continuous wave red laser seems to be a promising therapeutic option for the treatment of AA; however, additional studies are necessary to obtain more robust evidence.

Abstract
PURPOSE The purpose of this trial was to evaluate if photobiomodulation (PBM) can accelerate hair regrowth after chemotherapy in breast cancer patients and if this is correlated with a better quality of life (QoL). METHODS A randomized controlled trial with breast cancer patients that underwent an anthracycline and taxane-containing chemotherapy regimen was set up at the Jessa Hospital (Hasselt, Belgium). Patients were randomized into the control group (no intervention) or the PBM group (three PBM sessions each week for 12 weeks, starting the last day of their chemotherapy). Hair regrowth was evaluated based on photographic assessments. Two blinded researchers independently scored the hair regrowth using a numerical rating scale (NRS). In addition, the QoL was measured using the European Organization for Research and Treatment-QOL questionnaire and Breast Cancer-specific module (EORTC QLQ-C30 and QLQ-BR23). Data were collected on the day of their last chemotherapy session and 1, 2, and 3 months post-chemotherapy. RESULTS A total of 32 breast cancer patients were included in the trial between June 2020 and February 2022. Significantly higher NRS scores were observed in the PBM group at 1-month post-chemotherapy compared to baseline, whereas they remained constant in the control group. Patients allocated to the PBM group scored their global health significantly higher at all time points compared to the control. CONCLUSION Based on the results of the HAIRLASER trial, PBM seems to accelerate hair regrowth after chemotherapy in breast cancer patients resulting in an improved global health status and better body image. The study was registered in July 2019 at ClinicalTrials.gov (NCT04036994).

Abstract
Millions of new cancer patients receive chemotherapy each year. In addition to killing cancer cells, chemotherapy is likely to damage rapidly proliferating healthy cells, including the hair follicle keratinocytes. Chemotherapy causes substantial thinning or loss of hair, termed chemotherapy-induced alopecia (CIA), in approximately 65% of patients. CIA is often ranked as one of the most distressing adverse effects of chemotherapy, but interventional options have been limited. To date, only scalp cooling has been cleared by the US Food and Drug Administration (FDA) to prevent CIA. However, several factors, including the high costs not always covered by insurance, preclude its broader use. Here we review the current options for CIA prevention and treatment and discuss new approaches being tested. CIA interventions include scalp cooling systems (both non-portable and portable) and topical agents to prevent hair loss, versus topical and oral minoxidil, photobiomodulation therapy (PBMT), and platelet-rich plasma (PRP) injections, among others, to stimulate hair regrowth after hair loss. Evidence-based studies are needed to develop and validate methods to prevent hair loss and/or accelerate hair regrowth in cancer patients receiving chemotherapy, which could significantly improve cancer patients’ quality of life and may help improve compliance and consequently the outcome of cancer treatment.

Abstract
Introduction: Fixed drug eruption (FDE), a very specific adverse drug reaction and one of the most common types of drug eruption, generally resolves spontaneously within 7-10 days upon withdrawal of the causative agent; however, extensive and severe cases may also require systemic drug therapy. The present study aimed to report a case in which a broad spectrum of severe, painful lesions of FDE was managed with photobiomodulation therapy (PBMT). Case Report: A 31-year-old Caucasian woman presented with many extremely painful mucocutaneous lesions of FDE which had arisen 8 days before, following a long period of hospitalization. The lesions were not responsive to either corticosteroids or analgesics within 5 days, and then seven daily sessions of PBMT were proposed. Pain alleviation was achieved on the 1st day of PBMT, and the lesions showed an advanced course of healing on the 3rd day. Within 7 days of PBMT, the lesions were almost completely repaired. In a 3-month follow-up period, no relapse of any FDE lesion was reported. Conclusion: PBMT may be a promising strategy for the management of painful lesions of FDE refractory to conventional medication therapy. However, further studies are needed to confirm this hypothesis.

Abstract
Alzheimer's disease (AD) is one of the major neurodegenerative diseases and the most common form of dementia. Characterized by the loss of learning, memory, problem-solving, language, and other thinking abilities, AD exerts a detrimental effect on both patients' and families' quality of life. Although there have been significant advances in understanding the mechanism underlying the pathogenesis and progression of AD, there is no cure for AD. The failure of numerous molecular targeted pharmacologic clinical trials leads to an emerging research shift toward non-invasive therapies, especially multiple targeted non-invasive treatments. In this paper, we reviewed the advances of the most widely studied non-invasive therapies, including photobiomodulation (PBM), transcranial magnetic stimulation (TMS), transcranial direct current stimulation (tDCS), and exercise therapy. Firstly, we reviewed the pathological changes of AD and the challenges for AD studies. We then introduced these non-invasive therapies and discussed the factors that may affect the effects of these therapies. Additionally, we review the effects of these therapies and the possible mechanisms underlying these effects. Finally, we summarized the challenges of the non-invasive treatments in future AD studies and clinical applications. We concluded that it would be critical to understand the exact underlying mechanisms and find the optimal treatment parameters to improve the translational value of these non-invasive therapies. Moreover, the combined use of non-invasive treatments is also a promising research direction for future studies and sheds light on the future treatment or prevention of AD.

Abstract
Abstract
Background: Non-scarring alopecia areata (AA) is a disease that is mediated through autoimmunity. Recently, autologous platelet-rich plasma (PRP) and photobiomodulation (PBM), commonly known as low-level laser (or light, LLLT) have been suggested to provide a valuable role in stimulating the growth of hair follicles (HF)
Aim: Compare between the significance and wellbeing of PRP and LLLT in the management of AA.
Patients & methodology: Thirty patients, each having three patches of AA participated in the study. Patches were assigned randomly to have one of the two treatments: PRP or LLLT. The third patch served as a control and received placebo treatment. PRP was done once weekly whereas LLLT was done 3 sessions per week for a maximum of 6 weeks. Patients were followed up at one month and three months. The thickness and density of hair were evaluated by the folliscope.
Results: A noteworthy higher improvement was detected in the thickness and the density of hair in the PRP treated patches as evaluated by the folliscope and patients satisfaction. The obtained outcomes were sustained during the 12 week follow-up period in most of patients.
Conclusion: PRP and LLLT could be considered as efficacious alternatives for the treatments of AA with the least morbidity in addition to a little cost profit ratio.
KEYWORDS: Alopecia areata, platelet-rich plasma, folliscope, photobiomodulation, low level laser therapy.

Abstract
BACKGROUND Low-level light/laser therapy (LLLT) can potentially stimulate hair growth in pattern hair loss (PHL), with many available home-use LLLT devices of different designs and technology on the market. However, not all devices are cleared by the United States (US) Food and Drug Administration (FDA), with very few studies to support their efficacy. OBJECTIVES This systematic review and meta-analysis aimed to investigate the effectiveness of FDA-approved LLLT devices for PHL treatment. METHODS We included articles related to FDA-approved home-use LLLT devices on PubMed and Medline, using the FDA 510(K) Premarket Notification database and the systematic search of articles up to January 2020. The standardized mean difference (SMD) for the changes of hair density treated by LLLT versus sham devices was analyzed. RESULTS Only 32 home-use LLLT devices have been approved by the FDA as of January 2020. The meta-analysis comprised seven double-blinded, randomized, controlled trials. The overall quantitative analysis yielded a significant increase in hair density in those treated by LLLT versus sham groups (SMD: 1.27, 95% confidence interval [CI]: 0.993-1.639). The subgroup analysis demonstrated the increased hair growth in male and female subjects with both comb- and helmet-type devices. There were significant LLLT sources in the LDs alone (SMD: 1.52, 95% CI: 1.16-1.88) and the LDs combination (SMD: 0.85, 95% CI: 0.55-1.16) (p=0.043). CONCLUSION LLLT is potentially effective for PHL treatment. Nonetheless, the long-term follow-up study in patients with severe PHL with combined standard treatment and comparison between LLLT devices and energy sources is recommended.

A systematic review on the treatment of pediatric severe alopecia areata by topical immunotherapy or Anthralin (contact sensitization) or low-level light/laser therapy (LLLT): focus on efficacy, safety, treatment duration, recurrence, and follow-up based on clinical studies. J Cosmet Dermatol 2021; 21:2727-2741.

Abstract
INTRODUCTION Alopecia areata (AA) in its extensive and severe forms is treatment-challenging, especially in pediatrics. METHOD A PRISMA-compliant systematic review of seven electronic databases was searched by the terms "alopecia areata," "pediatric," "topical immunotherapy," "Anthralin," and "light therapy" from inception until March 2021. All the alternative names of the disease and therapies have been included in the search terms. 790 articles went to title abstract review by two independent reviewers. In the subsequent level, a review of the full text of studies was conducted. RESULTS Finally, 10 relevant articles in terms of content structure, subject coverage, and purpose, were selected for further review. The highest percentages of complete hair regrowth were 79.6% and 63.61% by SADBE (topical immunotherapy) and laser therapy. By Anthralin (contact sensitization), the complete response rate was below 50% (between 30 and 35%). Regarding average response, the most effective methods were local immunotherapy (with an average effectiveness of 53.8%), laser therapy (52.55%), and the use of Anthralin-induced contact dermatitis (30.86%), respectively. However, recurrence rate-after treatment with induced contact dermatitis by topical medications like Anthralin (contact sensitization)-was lower (mean 43.53%) in comparison with local immunotherapy (57%). In topical immunotherapy, light base therapy, and contact sensitization, the highest percentage of complete hair regrowth and the average response rate were (63.61% and 52.55%), (79.6% and 53.8%) and (32% and 30.8%), respectively. These methods are considered safe in children. CONCLUSION A high and more than 50% efficacy in hair regrowth could be expected by topical immunotherapy and light/laser therapy method. No serious side effects have been observed by these methods that are well tolerated in children. Therefore, a combination of local immunotherapy and light/laser therapy could be suggested for the treatment of extensive AA in children. The use of Anthralin could be associated with a lower but more durable response. These points are important for patient selection in individualized situations.

Abstract
It is estimated that chemotherapy-induced alopecia (CIA) occurs in 65% of chemotherapeutic patients. Forty-seven percent of cancer patients consider hair loss to be the most traumatic aspect of therapy. CIA can be anticipated, depending on the regimen used, and doctors should be aware of the treatments that can minimize it. Careful evaluation before chemotherapy treatment should be performed, and trichoscopy may be useful. Dermatologists do not generally evaluate postchemotherapy alopecia. However, there is an increasing number of reports of permanent chemotherapy-induced alopecia, and these patients require treatment.

Abstract
Treatment options for hair loss have traditionally been limited to topical and systemic therapies. Systemic therapies for inflammatory hair disorders are often immunosuppressive, and systemic treatment of androgenetic hair loss can cause undesired effects on sexual and reproductive health. Topical agents have a favorable side effect profile compared with systemic therapies, but many topicals have poor transcutaneous absorption, limiting their concentration and action at follicular targets in the dermis.

Abstract
Approximately 50% of the sunlight reaching the Earth's surface is visible light (400-700 nm). Other sources of visible light include lasers, light-emitting diodes, and flash lamps. Photons from visible light are absorbed by photoreceptive chromophores (e.g., melanin, heme, and opsins), altering skin function by activating and imparting energy to chromophores. Additionally, visible light can penetrate the full thickness of the skin and induce pigmentation and erythema. Clinically, lasers and light devices are used to treat skin conditions by utilizing specific wavelengths and treatment parameters. Red and blue light from light-emitting diodes and intense pulsed light have been studied as antimicrobial and anti-inflammatory treatments for acne. Pulsed dye lasers are used to treat vascular lesions in adults and infants. Further research is necessary to determine the functional significance of visible light on skin health without confounding the influence of ultraviolet and infrared wavelengths.

Abstract
Photobiomodulation, otherwise known as low-level laser (or light) therapy, is an emerging modality for the management of hair loss. Several randomized trials have demonstrated that it is safe and potentially effective on its own or in combination with standard therapies. These devices come in many forms including wearable caps or helmets that afford hands-free and discreet use. Models with light-emitting diodes (LEDs) are less expensive compared to laser-based devices and do not require laser safety considerations, thus facilitating ease of home use. Limitations include cost of the unit, risk of information bias, and lack of standardized protocols. Finally, as with any hair loss treatment, patients' expectations with regards to therapeutic outcomes must be managed.

Abstract
Low-level laser therapy (LLLT) is used to treat androgenetic alopecia (AGA). The therapeutic effect of LLLT on AGA has been evaluated; however, there is a paucity of studies that investigated device- and usage-related factors that may influence the effect of LLLT on hair regrowth. The literature was systematically searched to identify eligible studies; PubMed, Scopus, EMBASE and clinicaltrials.gov databases were searched on 30 April 2020. Eligible studies were randomized trials that investigated the effect of LLLT on hair density in AGA. Robust linear regressions were used to make comparisons. An increase in the per-session energy fluence by 1 J/cm2 is significantly associated with an increase in hair density by 0.23 hairs/cm2 (95% CI: 0.21 hairs/cm2 , 0.25 hairs/cm2 ). The number of laser or light-emitting diodes is not significantly associated with change in hair density. Increasing the total duration of exposure to treatment is associated with a significant increase in hair density (β = .53, P < .05). Switching from continuous to pulse irradiation was associated with a significant increase in hair density (β = 10.11, P < .01). Energy fluence, irradiation session duration, and light pulsing have a significant therapeutic effect on AGA, while the number of diodes does not.

Abstract
New strategies are necessary for the prevention of endodontic infections caused by Enterococcus faecalis, a common resistant pathogen and biofilm producer. Aim of the present study was to compare the effects of Near-Infrared (NIR) Light-Emitting Diode (LED) irradiation and different concentrations of sodium hypochlorite (NaOCl) alone or combined to each other on the E. faecalis biofilm, on artificial and human dentin surfaces. E. faecalis ATCC 29212 preformed biofilms, on polystyrene wells and on dentin discs, were treated with 880 nm NIR irradiation and NaOCl at 4%, 2.5%, 1% and 0.5% alone and combined to each other (NIR irradiation plus NaOCl 1% or 0.5%) at 5 and 10 min. Treated biofilms were compared to the controls for (i) biofilm biomass evaluation, (ii) CFU count for the quantification of cultivable cells and (iii) cells viability. All the detected experimental conditions displayed a significant reduction of biofilm biomass (p < 0.001) and CFUs/mL (p < 0.01) in respect to the controls on both tested surfaces. The effects on the E. faecalis biomass, colony count and cell viability were not time-dependent except for NaOCl 2.5% and 1% in the biofilm biomass reductions on human dentin discs. NIR-LED irradiation alone showed a reduction of E. faecalis aggregates without interfering with cell viability whereas NaOCl alone expressed a killing effect in a concentration dependent way. The combination of NIR-LED irradiation with NaOCl 1% and 0.5% displayed a double effect of cluster disaggregation and cell killing. In particular, NIR-LED irradiation combined with NaOCl 0.5% displayed an anti-biofilm activity major than those expressed by NaOCl 0.5% alone (p = 0.001) with a reduction of biomass 93% vs 71% and 97% vs 25% after 10 min, on polystyrene wells and human dentin discs, respectively. The innovative use of NIR-LED irradiation combined at short times with low concentration of NaOCl (1% and 0.5%) is capable to reach a significant effect on E. faecalis biofilm, especially on human dentin discs.
