Abstract
Breast cancer is a global health concern that requires personalized therapies to prevent relapses, as conventional treatments may develop resistance over time. Photothermal therapy using spectral radiation or intense light emission is a broad-spectrum treatment that induces hyperthermia-mediated cancer cell death. MXene, a two-dimensional material, has been reported to have potential biological applications in photothermal therapy for cancer treatment. In this study, we investigated the apoptotic activity of MXene and UV-irradiated MXene in MCF-7 breast cancer cells by treating them with varying concentrations of MXene. The cytotoxicity of MXene and UV was evaluated by analyzing cellular morphology, nuclei condensation, caspase activation, and apoptotic cell death. We also assessed the effect of the combined treatment on the expression and cellular distribution of Tubulin, a key component of microtubules required for cell division. At low concentrations of MXene (up to 100 µg/ml), the level of cytotoxicity in MCF-7 cells was low. However, the combined treatment of MXene and UV resulted in a synergistic increase in cytotoxicity, causing rounded cellular morphology, condensed nuclei, caspase activation, and apoptotic cell death. Furthermore, the treatment reduced Tubulin protein expression and cellular distribution, indicating a potent inducer of cell death with potential application for cancer treatment. The study demonstrates that the combined treatment of MXene and UVB irradiation is a promising strategy for inducing apoptotic cell death in breast cancer cells, suggesting its potential as a therapeutic intervention for breast cancer.

Abstract
The development of light-emitting diodes (LEDs) has led to an increase in the use of lighting regimes within medicine particularly as a treatment for dermatological conditions. New devices have demonstrated significant results for the treatment of medical conditions, including mild-to-moderate acne vulgaris, wound healing, psoriasis, squamous cell carcinoma in situ (Bowen's disease), basal cell carcinoma, actinic keratosis, and cosmetic applications. The three wavelengths of light that have demonstrated several therapeutic applications are blue (415 nm), red (633 nm), and near-infrared (830 nm). This review shows their potential for treating dermatological conditions. Phototherapy has also been shown to be an effective treatment for allergenic rhinitis in children and adults. In a double-anonymized randomized study it was found that there was 70% improvement of clinical symptoms of allergic rhinitis after intranasal illumination by low-energy narrow-band phototherapy at a wavelength of 660 nm three times a day for 14 consecutive days. Improvement of oedema in many patients with an age range of 7-17 were also observed. These light treatments can now be self-administered by sufferers using devices such as the Allergy Reliever phototherapy device. The device emits visible light (mUV/VIS) and infra-red light (660 nm and 940 nm) wavelengths directly on to the skin in the nasal cavity for a 3 min period. Several phototherapy devices emitting a range of wavelengths have recently become available for use and which give good outcomes for some dermatological conditions.

Abstract
Introduction Psoriasis affects children with a considerable burden in early life. Treating pediatric psoriasis is challenging also because of the lack of updated specific guidelines. With the recent approval of several biologics for pediatric psoriasis and the ongoing COVID-19 pandemic, the management of young psoriatic patients is facing major changes. A revision of treatment recommendations is therefore needed. Methods In September 2021, a board of six Italian dermatologists convened to update treatment recommendations. The board issued evidence- and consensus-based statements covering relevant areas of pediatric psoriasis, namely: assessment of psoriasis severity, management of children with psoriasis, and treatment of pediatric psoriasis. To reach consensus, the statements were submitted to a panel of 24 experts in a Delphi process performed entirely via videoconference. A treatment algorithm was produced. Results There was full consensus that psoriasis severity is determined by the extension/severity of skin lesions, site of lesions, and impact on patient quality of life. Agreement was reached on the need for a multidisciplinary approach to pediatric psoriasis and the importance of patient/parents education. The relevance of vaccinations, including COVID-19 vaccination, for psoriatic children was acknowledged by all participants. Management issues that initially failed to reach consensus included the screening for psoriasis comorbidities and early treatment with biologics to prevent them and the use of telemedicine to facilitate patient follow-up. There was full consensus that topical corticosteroids are the first choice for the treatment of mild pediatric psoriasis, while phototherapy and systemic therapy are used in children with moderate-severe psoriasis. According to the proposed treatment algorithm, biologics are the first line of systemic therapy. Conclusions Targeted systemic therapies are changing the treatment of moderate-severe pediatric psoriasis, while topical corticosteroids continue to be the first choice for mild disease. Children-centered research is needed to further improve the treatment of pediatric psoriasis.

Abstract
Psoriasis is a chronic inflammatory skin disease that affects up to 1.2% of children and adolescents. The treatment options for childhood psoriasis are often based on the same principles as in adults. However, most data on safety and efficacy derive from adult studies, and only a few of the frequently used treatments have achieved approval for use in children. The aim of this study was to review the current literature on off-label treatments for psoriasis in children and adolescents. We searched PubMed and identified 50 studies on off-label treatments. Of these, 23 studies were clinical trials (four randomized). There are only a small number of available studies on off-label treatments for children and adolescents with psoriasis, and many of these are retrospective reviews with few participants. Despite the current lack of studies, we still recommend the use of unapproved treatments since we have clinical experience with treatments such as topical corticosteroids, vitamin D analogs, and methotrexate that have shown promising effects. Regular clinical trials are needed to investigate the safety and efficacy of unapproved treatments. Due to The Pediatric Investigation Plans issued by The European Union, new drugs developed by pharmaceutical companies are required to undergo clinical trials in a pediatric population to get their application for marketing authorization processed. This will hopefully lead to much more data on the efficacy and safety of the new treatments, including treatments for children and adolescents with psoriasis.

Abstract
INTRODUCTION The dry and scaly skin of psoriatic patients decreases the efficacy of ultraviolet B (UVB) phototherapy. Different agents are used to facilitate the transmission of light, but most of these preparations are cosmetically unfavorable. We have tested a novel preparation containing sodium hyaluronate and nicotinic acid (UV Fotogel®; Pernix Ltd.) with the double aim to improve the efficacy of UVB phototherapy and assess the cosmetic acceptability of the preparation. METHODS Ninety patients with plaque psoriasis were enrolled in the study, of whom 44 received narrow-band UVB (NB-UVB) phototherapy. Prior to phototherapy, one side of the patient's body was treated with UV Fotogel while the other side served as a control. The other 46 patients used the preparation at their homes before regular sunbathing. The Local Psoriasis Severity Index (L-PSI), cosmetic acceptability and tolerability were recorded. The median values with the 25th and 75th percentiles (25p and 75p, respectively) were determined for the UV Fotogel-treated and control sites and then compared. RESULTS The sides of the body to which UV Fotogel was applied prior to NB-UVB phototherapy had a significantly lower median L-PSI score than the non-treated control sides at the end of the treatment (1.0 [25p-75p: 0.0-2.0] vs. 2.0 [1.0-3.0], respectively). The application of UV Fotogel prior to sunbathing also led to a significant decrease in L-PSI score. There was a significant reduction in the median L-PSI score of patients at the final visit compared to baseline (2.5 [25p-75p: 1.5-3.5] vs. 6.0 [6.0-7.0], respectively). Use of the preparation was not accompanied by considerable adverse effects, and the patients found it cosmetically acceptable. Application of UV Fotogel prior to sunbathing was well tolerated by the patients, and the cosmetic acceptability was also good. CONCLUSION UV Fotogel is potentially a useful device for enhancement of the efficacy of phototherapy in patients with psoriasis.

Abstract
BACKGROUND Topical agents used in combination with phototherapy or photochemotherapy may have both blocking or enhancing effects in ultraviolet rays. OBJECTIVE In this in vivo study, the effects of topical petrolatum, basis cream, glycerine, and olive oil on the transmission of ultraviolet A radiation were investigated. METHODS A test was performed to determine the minimal phototoxic dose on 29 volunteers with only psoralen plus ultraviolet A (PUVA) and then the same test was repeated with white petrolatum, basis cream, glycerine, olive oil, and sunscreen (0.3cc/25cm2). The effects of each agent on the minimal phototoxic dose were determined after 72 h. RESULTS When compared to pure PUVA, there was a statistically significant increase in the mean minimal phototoxic dose values by the application of white petrolatum (P = 0.011), but there was no significant increase or decrease in the mean minimal phototoxic dose values after the application of basis cream (P = 0.326), glycerine (P = 0.611) or olive oil (P = 0.799). STUDY LIMITATIONS Low number of patients Conclusion: The application of white petrolatum, which has a blocking effect, and also of basis cream immediately before PUVA therapy should not be recommended. Although we specify that glycerine and maybe olive oil can be used before photochemotherapy, there is a need for further research in larger series.

Abstract
Phototherapy can be a safe and effective treatment for various skin diseases in children. Special considerations governing the use of this treatment modality in pediatric populations include patient, family, and facility-based factors that are oriented around heightened concerns with regard to safety and tolerability of treatment. Although phototherapy has been found to be effective in a wide range of dermatologic conditions affecting pediatric populations, including psoriasis, atopic dermatitis, pityriasis lichenoides, cutaneous T-cell lymphoma, and vitiligo, there is need for additional research on other conditions in which phototherapy has shown promise.

Abstract
Narrow-band ultraviolet B (NBUVB) phototherapy is an important treatment modality in dermatology. The most common dermatological indications for NBUVB include psoriasis, atopic dermatitis and vitiligo; however, it has been found to be an effective and well-tolerated treatment option in various other dermatoses. The efficacy of NBUVB phototherapy compares favorably with other available photo(chemo)therapy options and its efficacy is further augmented by a number of topical and systemic adjuncts. The long-term safety of NBUVB phototherapy remains to be fully elucidated; however, available data now suggest that it is safe and well-tolerated. The objective of this review was to summarize the current understanding of the safety and efficacy of NBUVB phototherapy in dermatology.

Abstract
Phototherapy and photochemotherapy are well-described treatment modalities for psoriasis in adults. Like many other treatments, the experience and long-term safety of their use in children is limited. We conducted a literature search and identified publications reporting the use of phototherapy and photochemotherapy in pediatric populations. This article summarizes the existing literature on this topic. Although many studies report good improvement with these treatment modalities, long-term safety data on their use is lacking for pediatric patients.

Abstract
Onset of psoriasis in childhood is quite common. Chronicity, inflammation and hyperproliferation are the cardinal features by which the condition establishes its uniqueness. Clearance of disease may be farfetched in most patients and relapse is frequent. Early recognition and management of psoriasis in children and adolescents is vital in therapy in children.

Abstract
BACKGROUND Phototherapy is effective for many dermatoses in adults, but there is a paucity of data for its use in children. OBJECTIVES To review the efficacy and tolerability of narrowband UVB phototherapy in children at a tertiary centre in New Zealand, and determine if there were any factors that differentiated responders from non-responders. METHODS A prospective analysis of children (<16 years old) who had undergone phototherapy over a 15-year period. RESULTS 116 children received phototherapy with a total of 144 courses. Mean age was 11.0 years with the majority being European and having skin phototype II. Atopic dermatitis was the most common indication for treatment followed by psoriasis, pityriasis lichenoides, nodular prurigo, morphea, vitiligo, urticaria pigmentosa and erythropoietic porphyria. Treatment was effective in the majority of children (72%). Most received only one course. For responders, the mean number of treatments was 32.4. The mean dose per treatment to achieve clearance was 886 mJ/cm(2) and the mean maximum treatment dose per treatment was 1328 mJ/cm(2) . All children tolerated treatment well with 36% developing brief, minimally symptomatic, erythema. Only two children experienced exacerbations of their underlying dermatoses. CONCLUSIONS This study shows that phototherapy is an effective and well-tolerated treatment modality in children.

Abstract
Phototherapeutic modalities, including narrowband-UVB, broadband-UVB, PUVA photochemotherapy, and excimer laser therapy are valuable tools that can be used for photoresponsive dermatoses in children. As a systematically safer alternative compared with internal agents, including the prebiologic and biological therapies, phototherapy should be considered a possible treatment option for children with diseases including psoriasis, atopic dermatitis, pityriasis lichenoides chronica, and vitiligo.
