Abstract
Pulsed dye laser (PDL) therapy can be effective in treating psoriasis, with a long duration of remission. Although PDL therapy, albeit on a modest scale, is being used for decades now, the underlying mechanisms responsible for the long-term remission of psoriasis remain poorly understood. The selective and rapid absorption of energy by the blood causes heating of the vascular wall and surrounding structures, like perivascular nerves. Several studies indicate the importance of nerves in psoriatic inflammation. Interestingly, denervation leads to a spontaneous remission of the psoriatic lesion. Among all dermal nerves, the perivascular nerves are the most likely to be affected during PDL treatment, possibly impairing the neuro-inflammatory processes that promote T-cell activation, expression of adhesion molecules, leukocyte infiltration and cytokine production. Repeated PDL therapy could cause a prolonged loss of innervation through nerve damage, or result in a 'reset' of neurogenic inflammation after temporary denervation. The current hypothesis provides strong arguments that PDL treatment affects nerve fibres in the skin and thereby abrogates the persistent and exaggerated inflammatory process underlying psoriasis, causing a long-term remission of psoriasis.

Abstract
BACKGROUND Hypertrophic and keloid scars are common skin conditions resulting from abnormal wound healing. They can cause itching, pain and have a negative physical and psychological impact on patients' lives. Different approaches are used aiming to improve these scars, including intralesional corticosteroids, surgery and more recently, laser therapy. Since laser therapy is expensive and may have adverse effects, it is critical to evaluate the potential benefits and harms of this therapy for treating hypertrophic and keloid scars. OBJECTIVES To assess the effects of laser therapy for treating hypertrophic and keloid scars. SEARCH METHODS In March 2021 we searched the Cochrane Wounds Specialised Register, CENTRAL, MEDLINE, Embase, CINAHL EBSCO Plus and LILACS. To identify additional studies, we also searched clinical trials registries for ongoing and unpublished studies, and scanned reference lists of relevant included studies as well as reviews, meta-analyses, and health technology reports. There were no restrictions with respect to language, date of publication, or study setting. SELECTION CRITERIA We included randomised controlled trials (RCTs) for treating hypertrophic or keloid scars (or both), comparing laser therapy with placebo, no intervention or another intervention. DATA COLLECTION AND ANALYSIS Two review authors independently selected studies, extracted the data, assessed the risk of bias of included studies and carried out GRADE assessments to assess the certainty of evidence. A third review author arbitrated if there were disagreements. MAIN RESULTS We included 15 RCTs, involving 604 participants (children and adults) with study sample sizes ranging from 10 to 120 participants (mean 40.27). Where studies randomised different parts of the same scar, each scar segment was the unit of analysis (906 scar segments). The length of participant follow-up varied from 12 weeks to 12 months. All included trials had a high risk of bias for at least one domain: all studies were deemed at high risk of bias due to lack of blinding of participants and personnel. The variability of intervention types, controls, follow-up periods and limitations with report data meant we pooled data for one comparison (and only two outcomes within this). Several review secondary outcomes - cosmesis, tolerance, preference for different modes of treatment, adherence, and change in quality of life - were not reported in any of the included studies. Laser versus no treatment: We found low-certainty evidence suggesting there may be more hypertrophic and keloid scar improvement (that is scars are less severe) in 585-nm pulsed-dye laser (PDL) -treated scars compared with no treatment (risk ratio (RR) 1.96; 95% confidence interval (CI): 1.11 to 3.45; two studies, 60 scar segments). It is unclear whether non-ablative fractional laser (NAFL) impacts on hypertrophic scar severity when compared with no treatment (very low-certainty evidence). It is unclear whether fractional carbon dioxide (CO2) laser impacts on hypertrophic and keloid scar severity compared with no treatment (very low-certainty evidence). Eight studies reported treatment-related adverse effects but did not provide enough data for further analyses. Laser versus other treatments: We are uncertain whether treatment with 585-nm PDL impacts on hypertrophic and keloid scar severity compared with intralesional corticosteroid triamcinolone acetonide (TAC), intralesional Fluorouracil (5-FU) or combined use of TAC plus 5-FU (very low-certainty evidence). It is also uncertain whether erbium laser impacts on hypertrophic scar severity when compared with TAC (very low-certainty evidence). Other comparisons included 585-nm PDL versus silicone gel sheeting, fractional CO2 laser versus TAC and fractional CO2 laser versus verapamil. However, the authors did not report enough data regarding the severity of scars to compare the interventions. As only very low-certainty evidence is available on treatment-related adverse effects, including pain, charring (skin burning so that the surface becomes blackened), telangiectasia (a condition in which tiny blood vessels cause thread-like red lines on the skin), skin atrophy (skin thinning), purpuric discolorations, hypopigmentation (skin colour becomes lighter), and erosion (loss of part of the top layer of skin, leaving a denuded surface) secondary to blistering, we are not able to draw conclusions as to how these treatments compare. Laser plus other treatment versus other treatment: It is unclear whether 585-nm PDL plus TAC plus 5-FU leads to a higher percentage of good to excellent improvement in hypertrophic and keloid scar severity compared with TAC plus 5-FU, as the certainty of evidence has been assessed as very low. Due to very low-certainty evidence, it is also uncertain whether CO2 laser plus TAC impacts on keloid scar severity compared with cryosurgery plus TAC. The evidence is also very uncertain about the effect of neodymium-doped yttrium aluminium garnet (Nd:YAG) laser plus intralesional corticosteroid diprospan plus 5-FU on scar severity compared with diprospan plus 5-FU and about the effect of helium-neon (He-Ne) laser plus decamethyltetrasiloxane, polydimethylsiloxane and cyclopentasiloxane cream on scar severity compared with decamethyltetrasiloxane, polydimethylsiloxane and cyclopentasiloxane cream. Only very low-certainty evidence is available on treatment-related adverse effects, including pain, atrophy, erythema, telangiectasia, hypopigmentation, regrowth, hyperpigmentation (skin colour becomes darker), and depigmentation (loss of colour from the skin). Therefore, we are not able to draw conclusions as to how these treatments compare. AUTHORS' CONCLUSIONS: There is insufficient evidence to support or refute the effectiveness of laser therapy for treating hypertrophic and keloid scars. The available information is also insufficient to perform a more accurate analysis on treatment-related adverse effects related to laser therapy. Due to the heterogeneity of the studies, conflicting results, study design issues and small sample sizes, further high-quality trials, with validated scales and core outcome sets should be developed. These trials should take into consideration the consumers' opinion and values, the need for long-term follow-up and the necessity of reporting the rate of recurrence of scars to determine whether lasers may achieve superior results when compared with other therapies for treating hypertrophic and keloid scars.

Abstract
Laser technology represents a major advance in the treatment of vascular changes. Excellent knowledge combined with technological advances in new laser sources form the basis of this safe and effective option in many acquired or congenital vascular changes on the face. With regard to the different laser sources, the pulsed dye laser (PDL) has the best efficacy-to-safety ratio. This type of laser remains the gold standard for vascular lesions. Neodymium-doped yttrium aluminium garnet (Nd: YAG) lasers and diode lasers, among others, as well as intensed pulsed light (IPL), play an important role in addressing vascular changes in the face. Good knowledge of the laser approach to vascular lesions and technological progress have led to safety features that seek to minimize side effects. These advances mainly include the introduction of cooled tips, cooling devices and cooling systems, changes in pulse duration, and the introduction of different wavelengths, among others. However, undesirable side effects can still occur. Although these are mostly discrete and resolve spontaneously, some complications can be serious and difficult to manage. Therefore, the prevention and early management of complications are all the more important in the treatment of vascular changes on the face.

Abstract
Sarcoidosis is a systemic granulomatous disease of unknown etiology that most frequently occurs in the lungs. However, cutaneous lesions are often the primary sign. Cutaneous sarcoidosis is difficult to treat, although different therapies have been applied. We herein report a case in which cutaneous sarcoidosis was treated with pulsed-dye laser (PDL) therapy along with oral administration of acitretin and hydroxychloroquine; no topical medications were applied. All patient details are de-identified. The treatment areas gradually improved after several courses of PDL therapy. This case illustrates that PDL therapy can serve as an auxiliary treatment for cutaneous sarcoidosis.

Abstract
Objectives: To investigate the efficacy of erbium-doped yttrium aluminium garnet (Er:YAG) laser in the treatment of solar lentigines. Methods: A retrospective study was conducted on patients treated with the only Er:YAG laser. In this study, 14 patients with multiple solar lentigines before treatment were included. Treatment parameters and all side effects were recorded. One independent, blinded dermatologist evaluated the clinical improvement and the patients also scored their satisfaction degree with the treatment. Results: The mean age of the patients was 41.07±7.16 years. The number of mean treatment session for each patient was 1.79±1.05. At the final visit, excellent improvement (76–100% clearance) was reached in eight (57.1%) patients, while good improvement (51-75% clearance) was achieved in five (35.7%) patients. Ten patients (71.4%) were very satisfied and four (28.5%) patients were satisfied with the results of the treatment. No side effects occurred. Conclusion: Er:YAG laser treatment may be an effective and safe optional modality for solar lentigines.

Abstract
Keloids are pathological scars that grow over time and extend beyond the initial site of injury after impaired wound healing. These scars frequently recur and rarely regress. They are aesthetically disfiguring, can cause pain, itching, discomfort as well as psychological stress, often affecting quality of life. Many treatment modalities, including surgical and non-surgical, have been explored and have been reported to be beneficial; however, none have been absolutely satisfactory or optimal for the treatment of all keloid subtypes to date. This poses a major challenge to clinicians. Often, a combinational therapeutic approach appears to offer the best results with higher patient satisfaction compared to monotherapy. The aetiopathogenesis of keloids is not fully elucidated; however, with recent advances in molecular biology and genetics, insight is being gained on the complex process of scar formation and hence new therapeutic and management options for keloids. In this paper, we explore the literature and summarise the general concepts surrounding keloid development and review both current (corticosteroids, surgical excision, silicone-based products, pressure therapy, radiotherapy, cryotherapy, laser therapy, imiquimod and 5-fluorouracil) and emerging (stem cell therapy, mitomycin C, verapamil, interferons, bleomycin, botulinum toxin type A and angiotensin-converting enzyme inhibitors) treatments. Increased knowledge and understanding in this area may potentially lead to the discovery and development of novel therapeutic options that are more efficacious for all keloid types. LAY SUMMARY Keloids are problematic scars that are difficult to treat and manage. The aetiopathogenesis of keloids is not clear; however, recent advances in molecular biology and genetics are beginning to shed light on the underlying mechanisms implicated in keloid scar formation which will hopefully lead to the development of treatment options for all keloid types. This review summarises current and emerging therapies.

Abstract
BACKGROUND In the recent past, long pulsed dye lasers (LPDL) have been investigated for the treatment of epidermal pigmented lesions (EPLs). Using a pigmented lesion compression headpiece, blood is pushed laterally out of the laser field focusing laser energy on melanin. Recent studies have demonstrated excellent responses using a single-pulse at the following settings: 9-12 J/cm2 , 1.5 milliseconds, 7-10 mm spot size with compression. However, the majority of these studies report patients requiring up to four treatments for lesion resolution. Herein, we describe our experiences utilizing a back-to-back double-pulse technique to decrease the total number of treatments needed for EPL clearance. METHODS Thirty-six patients (27 females, 9 males; skin types I-IV) with benign facial EPLs were included. Each lesion received two back-to-back pulses (fluence of 9-12 J/cm2 , 1.5 milliseconds duration, and 7 mm spot size). If needed, a second treatment was delivered 4-8 weeks later. Pre- and post-photos after the first treatment were evaluated by two independent board-certified dermatologists. RESULTS Lesion clearance after the first treatment was graded on a Likert scale as: 1 = poor (<25% clearance); 2 = fair (25-50%); 3 = good (51-75%); and 4 = excellent (>75%). Of the 36 participants, 23 had excellent clearing, 10 with good, 2 with fair and 1 with poor clearance. There was only one case of post-inflammatory hyperpigmentation that subsequently resolved, and no cases or scarring or hypopigmentation. CONCLUSION LPDL with compression continues to be a safe and effective modality for treatment of EPLs. Double-pulsing decreases the total number of treatments needed for lesion resolution, while maintaining safety and potentially decreasing cost. Lasers Surg.

Abstract
Introduction: In recent years, the positive effect of fractional CO2 laser on increasing collagen fibers, and consequently its effect on treating striae has been suggested. The present study aims to assess the effectiveness of CO2 fractional laser 10600-nm in the treatment of striae alba. Methods: In this prospective clinical trial, 2 treatment sessions of fractional CO2 laser with 4-week interval was given to 30 patients with striae alba. Cutaneous resonance running time (CRRT) was measured at baseline and at week 4 and 3 months after the last session of laser therapy. The level of improvement was assessed by 2 independent dermatologists and patients after 3 months of follow up. Results: 16.7% of patients had moderate improvement, 63.3% had minimal improvement, and 20% had no improvement. A statistical significant difference was found in median CRRT during the study (P < 0.0001). The median CRRT levels were significantly higher in week 4 and 3 months after the last treatment compared to the baseline (both P < 0.001). Likewise, a significant increase was observed in median CRRT level from week 4 till the end of study (P < 0.001). Evaluation of participant satisfaction revealed that 10% were very satisfied, 10% satisfied, 3.3% slightly satisfied, and 76.7% unsatisfied. Conclusion: Striae alba remain a challenging condition to treat. The treatment of striae alba with CO2 fractional laser results in minimal improvement with mild side effects.

Abstract
Verruca vulgaris (VV) is a prevalent skin condition caused by various subtypes of human papilloma virus (HPV). The most common causes of non-genital lesions are HPV types 2 and 4, and to a lesser extent types 1, 3, 26, 29, and 57. Although numerous therapeutic modalities exist, none is universally effective or without adverse events (AE). Pulsed dye laser (PDL) is a favorable option due to its observed efficacy and relatively low AE rate. However, it is not known which verrucae are most likely to respond to PDL, or whether the causative viral subtype influences this response. The objective of this prospective blinded study was to assess whether the HPV subtype was predictive of response to PDL. For that matter, 26 verrucae from 26 immunocompetent patients were biopsied prior to treatment by PDL. HPV coding sequences were isolated and genotyped using PCR analysis. Patients were treated by PDL (595 nm wavelength, 5 mm spot size, 1.5 ms pulse duration, 12 J/cm2 fluence) once a month for up to 6 months, and clinical response was assessed. Binary logistic regression analysis and linear logistic regression analysis were used in order to evaluate statistical significance. Different types of HPV were identified in 22 of 26 tissue samples. Response to treatment did not correlate with HPV type, age, or gender. As no association between HPV type and response to PDL therapy could be established, it is therefore equally effective for all HPV types and remains a favorable treatment option for all VV.

Abstract
Psoriasis is an autoimmune inflammatory skin disease. In the past several decades, phototherapy has been widely used to treat stable psoriatic lesions, including trunk, scalp, arms and legs, and partial nail psoriasis. A variety of light/lasers with different mechanisms of action have been developed for psoriasis including ultraviolet B (UVB), psoralen ultraviolet A (PUVA), pulsed dye laser (PDL), photodynamic therapy (PDT), intense pulsed light (IPL), light-emitting diodes (LED), and so on. Because light/laser each has specific therapeutic and adverse effects, it is important to adequately choose the sources and parameters in management of psoriasis with different pathogenic sites, severities, and duration of the disorder. This review aims at providing most updated clinic information to physicians about how to select light/laser sources and individual therapeutic regimens. To date, UV light is primarily for stable plaque psoriasis and PDL for topical psoriatic lesions with small area, both of which are safe and effective. On the other hand, PUVA has better curative effects than UVB for managing refractory psoriasis plaques, if its side effects can be better controlled. PDL provides optimal outcomes on nail psoriasis compared with other lasers. Although the trails of low-level light/laser therapy (LLLT) are still small, the near infrared (NIR) and visible red light with low energy show promise for treating psoriasis due to its strong penetration and encouraging photobiomodulation. IPL is rarely reported for psoriasis treatment, but PDT-IPL has been found to offer a moderate effect on nail psoriasis. In brief, various phototherapies have been used either in different combinations or as monotherapy. The modality has become a mainstay in the treatment of mild-to-moderate psoriasis without systemic adverse events in today's clinical practice.

Abstract
Flash-lamp pulsed-dye laser (FPDL) is a nonablative technology, typically used in vascular malformation therapy due to its specificity for hemoglobin. FPDL treatments were performed in a large group of patients with persistent and/or recalcitrant different dermatological lesions with cutaneous microvessel involvement. In particular, 149 patients (73 males and 76 females) were treated. They were affected by the following dermatological disorders: angiokeratoma circumscriptum, genital and extragenital viral warts, striae rubrae, basal cell carcinoma, Kaposi's sarcoma, angiolymphoid hyperplasia, and Jessner-Kanof disease. They all underwent various laser sessions. 89 patients (59.7%) achieved excellent clearance, 32 patients (21.4%) achieved good-moderate clearance, 19 patients (12.7%) obtained slight clearance, and 9 subjects (6.1%) had low or no removal of their lesion. In all cases, FPDL was found to be a safe and effective treatment for the abovementioned dermatological lesions in which skin microvessels play a role in pathogenesis or development. Further and single-indication studies, however, are required to assess a standardized and reproducible method for applying this technology to “off-label” indications.

Abstract
Since their earliest description, keloids and hypertrophic scars have beleaguered patients and clinicians alike. These scars can be aesthetically disfiguring, functionally debilitating, emotionally distressing, and psychologically damaging, culminating in a significant burden for patients. Our current understanding of keloid pathophysiology has grown and continues to advance while molecular biology, genetics, and technology provide ever-deepening insight into the nature of wound healing and the pathologic perturbations thereof. Greater understanding will lead to the development and application of refined therapeutic modalities. This article provides an overview of our current understanding of keloids, highlighting clinical characteristics and diagnostic criteria while providing a comprehensive summary of the many therapeutic modalities available. The proposed mechanism, application, adverse events, and reported efficacy of each modality is evaluated, and current recommendations are summarized.

Abstract
Context: Striae distensae are linear atrophic dermal scars covered with flat atrophic epidermis. They may cause disfigurement, especially in females. Many factors may cause striae distensae such as steroids, obesity, and pregnancy. Although there is no standard treatment for striae; many topical applications, peeling, and light and laser systems have been tried. Aims: To evaluate and compare the efficacy of fractional CO2 laser with intense pulse light in treating striae distensae. Subjects and Methods: Forty patients with striae distensae were recruited. Twenty of them were treated by fractional CO2 laser and 20 were treated with intense pulse light. Length and width of the largest striae were measured pre- and post-treatment. Patient satisfaction was also evaluated and graded. Patients were photographed after each treatment session and photos were examined by a blinded physician who had no knowledge about the cases. Results: Both groups showed significant improvement after treatments (P < 0.05). Patients treated with fractional CO2 laser showed significant improvement after the fifth session compared with those treated with ten sessions of intense pulsed light (P < 0.05) in all parameters except in the length of striae (P > 0.05). Conclusions: The current study has provided supportive evidence to the effectiveness of both fractional CO2 laser and intense pulse light as treatments for striae distensae. Fractional CO2 laser was found to be more effective in the treatment of striae distensae compared with intense pulse light.

Abstract
BACKGROUND AND AIMS The pulsed dye laser (PDL) is recognized both as an effective treatment for vascular malformations and the as first treatment of choice for these lesions. However, PDL irradiation has poor efficacy in some patients, particularly the elderly. The present study histologically assessed such patients to try to elucidate the reason. MATERIALS AND METHODS A pulsed dye laser was used in 3 subjects in whom previous laser treatment was ineffective. Three-millimeter punch biopsies were obtained before laser treatment, 1 week and 3 months after the laser treatment. Each specimen was stained with toluidine blue and examined under light microscopy followed by electron microscopy with oolong tea extract (OTE) staining. RESULTS Microscopy revealed an increase in the vasculature at baseline and an increased number of dermal fibroblasts. One week post-irradiation, inflammatory cell infiltration was observed together with extensive interstitial perivascular edema. At 1 week and 3 months after laser irradiation, normal structures were observed for both blood vessels and capillary endothelial cells. Mild changes were noted in other interstitial features, but findings obtained 3 months after irradiation were almost similar to those before irradiation. CONCLUSIONS The lower efficacy of PDL treatment in the elderly was possibly due to the markedly low amount of red blood cells in our subjects' blood vessels, a major chromophore for the PDL, was markedly low. It is possible that age-related denaturation of dermal matrix collagen plays some role in maintaining the vasculature in the interstitium with edema, and inflammatory cell infiltration could lead to the cellular release of some cytokines which favor reconstruction of the vasculature.

Abstract
There are numerous cutaneous disorders that affect the foot, but of these conditions skin infections have the most significant impact on overall patient morbidity and clinical outcome. Skin infections in foot and ankle patients are common, with often devastating consequences if left unrecognized and untreated in both surgical and nonsurgical cases. There is a diverse array of infectious dermatoses that afflict the foot and ankle patient including tinea pedis, onychomycosis, paronychia, pitted keratolysis, verruca, folliculitis, and erysipelas. Prompt diagnosis, treatment, and surveillance of these common infectious conditions are critical in managing these dermatoses that can potentially progress to form deep abscesses and osteomyelitis. Infections can be managed with a combination of ventilated shoewear and synthetic substances to keep the feet dry, topical and oral antimicrobial agents, and patient education regarding preventative hygiene measures. The purpose of this review is to aid foot and ankle surgeons and other physicians in the diagnosis and treatment of infectious dermatoses affecting the foot.

Abstract
OBJECTIVE To investigate connective tissue growth factor (CTGF) expression before and after pulsed dye laser (PDL, 595 nm) treatment, and to better understand the mechanism of PDL treatment of keloids. METHOD Twenty-six patients with keloids were recruited for this study. For each patient, two keloids of similar anatomic location, duration, texture, and appearance were chosen for study; one of these keloids was treated and the other served as a control. Three sessions of PDL treatment, with pulse duration of 1.5 milliseconds, spot size 7 mm, DCD duration 20 milliseconds/delay 10 milliseconds and fluence of 10 J/cm(2), were performed on the keloids at 3- to 4-week intervals. Punch biopsies were performed both on the treated and untreated keloids prior to the first treatment and after the final treatment. The specimens underwent realtime polymerase chain reaction (PCR) and immunohistochemistry (IHC) to investigate the CTGF mRNA and protein expression after PDL treatment. RESULTS According to realtime PCR, the CTGF mRNA was significantly down-regulated after PDL treatment in 80.77% of patients as compared to the control group. IHC investigation showed that after treatment the CTGF positive cells also significantly decreased in number as compared to the control group in 80.77% of patients. Using the Vancouver scar scale (VSS), there was an average decrease of 20.85 ± 12.33% after PDL treatment. CONCLUSIONS Pulsed dye laser treatment of keloids significantly down-regulates the expression of CTGF in most cases. This may partially explain the mechanism of action of PDL treatment of keloids.

Abstract
Dermatofibroma (DF), a common benign skin tumour, sometimes requires treatment either because of cosmetic concern or for associated symptoms. However, no effective treatment with optimal cosmetic outcomes has been reported. An effective and safe therapeutic option could be treatment with pulsed dye laser (PDL). Twenty-two DFs in 15 patients were treated with PDL at 595-nm wavelength, using a spot size of 7 mm, a pulse duration of 2 ms and a fluence of 11 J/cm(2) with 2 or 3 stacked pulses. Clinical and dermoscopic photographs were taken before and after therapy. Global clinical improvement was higher than 50% in 12 lesions. Patient satisfaction assessment showed 73% of patients as satisfied or very satisfied. All lesions showed changes from the previous dermoscopic pattern. We consider that PDL could be a safe, palliative treatment as it is well accepted by patients and has a better cosmetic outcome than surgical excision.

Abstract
BACKGROUND Clinical manifestations of cutaneous lupus erythematosus (CLE) vary widely, and different subtypes of this autoimmune disease exist. Tumidus subtype (LT) has been recently separated from the chronic subtypes and is now considered an independent entity due to its particular clinical and histological features. Different treatments are usually prescribed for CLE. Our group has experience of CLE effectively treated with pulsed dye laser (PDL). It was our impression that better responses were achieved in the LT subtype, but no controlled prospective studies with PDL have been specifically performed. MATERIALS AND METHODS A prospective study was performed on 10 patients with histologically confirmed LT treated with PDL. All patients were treated with 595 nm PDL using the 10 mm spot size at 0.5 ms pulse width and a fluence of 8 J/cm(2). Biopsies were taken before and 4 weeks after treatment and were stained with haematoxylin-eosin. RESULTS Evaluation after PDL treatment showed clinical improvement in all of them without side-effects and reduction of the dermal lymphocytic infiltrate in 9/10 of the patients. Epidermal changes were absent in all patients. Mucin deposition persisted only in one patient. However, 50% of the patients developed new lesions nearby or distant to the treated zones. CONCLUSIONS PDL therapy is an effective and fast treatment option for acute flares of LT; however, it does not prevent recurrences. A histological improvement has been confirmed in this study. Purpura seems to be necessary to achieve a good response.

Abstract
Background: Although cryotherapy is still the first-line therapy for solar lentigines, because of the side effects such as post-inflammatory hyperpigmentation (PIH), especially in patients with darker skin types, pigment-specific lasers should be considered as a therapy for initial treatment. Aim: The aim of this study is to evaluate the efficacy and safety of cryotherapy compared with 595-nm pulsed dye laser (PDL) with cutaneous compression in the treatment of solar lentigines. Materials and Methods: Twenty-two patients (skin type II–IV) with facial or hand lentigines participated in this study. Lesions of one side of the face or each hand were randomly assigned and treated with either cryotherapy or PDL. Treatments were performed with radiant exposures of 10 J/cm2 , 7-mm spot size and 1.5 ms pulse duration with no epidermal cooling. Photographs were taken before treatment and 1-month later. The response rate and side effects were compared. Results: PDL was more likely to produce substantial lightening of the solar lentigines than cryotherapy, especially in skin type III and IV (n = 8, n = 9; P < 0.05), but might be no difference in type II (n = 5; P > 0.05). PIH was seen only in cryotherapy group. PDL group had only minimal erythema. No purpura was observed. Conclusion: PDL with compression is superior to cryotherapy in the treatment of solar lentigines in darker skin types.

Abstract
Acne is a domain in which the technology and understanding of light/laser therapeutic procedures have advanced considerably. The aim of the paper was to revisit adjunctive physical treatments of acne, including light/laser treatments and photodynamic therapy. This review summarizes findings about such treatment modalities with particular emphasis on efficacy and safety. A number of laser/light-based modalities have been developed to meet the increasing demand for new acne treatments. The current devices correspond, on the one hand, to light-emitting diode therapy and, on the other hand, to the 532-nm potassium titanyl phosphate laser, the 585- and 595-nm pulsed dye laser, the 1450-nm diode laser, the 1320-nm Nd:YAG laser and intense pulsed light. Photodynamic therapy is also available. It is claimed that light/laser treatments might induce a faster response compared with the 1-3 months needed for response to traditional oral and topical treatments. In conclusion, pulsed dye laser shows efficacy in some patients with mild to moderate acne. The relative effectiveness compared with other treatments is unconfirmed; from the published information, evidence-based efficacy assessment of light/laser therapies in acne remains almost impossible.

Abstract
Darier disease is often associated with pruritus and an unpleasant odor, causing medical and emotional problems. Ablative laser therapy has proven effective in ameliorating these symptoms. Side effects of this approach include permanent hypopigmentation and a risk of scarring. We present two cases where non-ablative therapy with pulsed dye lasers proved a safe and effective way to manage the intertriginous lesions. Although the mechanism of action is unclear, our success indicates that pulsed dye laser therapy is an option in Darier disease. Larger numbers of patients, ideally in multicenter studies, must be treated in this way to confirm our results.
