Abstract
Excimer light is a subtype of NB-UVB that emits a 308 nm wavelength, and can provide targeted phototherapy treatment. The absorption of 308 nm light by skin cells leads to therapeutic response in various common and ultraviolet-responsive skin diseases, such as psoriasis and vitiligo, and photo-resistant skin diseases such as prurigo nodularis, localized scleroderma, genital lichen sclerosis, and granuloma annulare, cutaneous T-cell lymphomas, among others. Excimer light has few adverse reactions and overall is well tolerated by patients, furthermore, it can be performed in places that are difficult to access. This article aims to explain the therapeutic bases and applications of excimer light in current dermatology.

Selection of Quality Indicators for the Certification of Psoriasis Units: The CUDERMA Project Delphi Consensus Study. ACTAS DERMO-SIFILIOGRAFICAS 2023; 114:865-883. [PMID: 36796538 DOI: 10.1016/j.ad.2023.02.002] [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: 02/06/2023] [Accepted: 02/06/2023] [Indexed: 02/17/2023] Open
Abstract
Defining quality indicators is a key strategy for ensuring the quality and standardization of health care. The CUDERMA project, an initiative of the Spanish Academy of Dermatology and Venerology (AEDV), was undertaken to define quality indicators for the certification of specialized units in dermatology; the first 2 areas selected were psoriasis and dermato-oncology. The aim of this study was to reach a consensus on what should be assessed by the indicators used to certify psoriasis units. The structured process used to do this comprised a literature review to identify potential indicators, the selection of an initial set of indicators to be evaluated by a multidisciplinary group of experts and, finally, a Delphi consensus study. A panel of 39 dermatologists evaluated the selected indicators and classified them as either "essential" or "of excellence". Consensus was finally reached on 67 indicators, which will be standardized and used to develop the certification standard for psoriasis units.

Abstract
INTRODUCTION AND OBJECTIVES The starting dose for narrowband UV-B phototherapy is determined by a patient's skin phototype or minimal erythema dose (MED). Calculation of MED identifies patients with unsuspected photosensitivity. The aim of this study was to investigate the influence of factors such as concomitant use of photosensitizing agents, diagnosis, and combination with acitretin in patients with psoriasis on the frequency and severity of adverse effects in patients with a low MED to narrowband UV-B phototherapy. MATERIAL AND METHODS We undertook a retrospective observational cohort study between February 1, 2009 and March 31, 2015. MED values were classified as normal or low. RESULTS In total, 302 patients with different skin conditions started narrowband UV-B phototherapy at a dose determined by their MED. No differences were found between patients with a low MED and those with a normal MED for number of drugs taken (P=.071) or use of photosensitizing agents (P=0.806). Following adjustment for age, sex, and phototype, the multivariate analysis showed that psoriasis exerted a protective effect against a low MED (OR=0.31 [95% CI, 0.16-0.58]). No significant risk of erythema or pruritus was detected in patients with a low MED (OR=1.68; 95% CI, 0.91-3.29 and OR=2.04; 95% CI, 0.99-4.22, respectively). CONCLUSIONS Psoriasis protects against a low MED. Although erythema and pruritus were more common in patients with a low MED, the differences were not significant.

Abstract
Photodynamic therapy (PDT) is an intensively studied part of medicine based on free radicals. These reactive species, extremely harmful for whole human organism, are used for eradication numerous diseases. Specific structure of ill tissues causes accumulation free radicals inside them without attack remaining healthy tissues. A rapid development of medicine and scientific research has led to extension of PDT towards treatment many diseases such as cancer, herpes, acne and based on antimicrobials. The presented review article is focused on the aforementioned disorders with accurate analysis of the newest available scientific achievements. The discussed cases explicitly indicate on high efficacy of the therapy. In most cases, free radicals turned out to be solution of many afflictions. Photodynamic therapy can be considered as promising treatment with comparable effectiveness but without side effects characteristic for chemotherapy.

Abstract
Psoriasis is a chronic inflammatory disease affecting mainly the skin but which can be complicated by psoriatic arthritis (PsA).This autoimmune skin disorder concerns 2-5% of the world population. To date, the physiopathology of psoriasis is not still completely elucidated but many researches are ongoing which have led for example to the discovery of the Th17/Th22 pathway. The conventional therapeutic approaches (local or systemic route) appeal to various classes of drugs with complex mechanisms of action and non-negligible side effects. Although there is no therapy capable to cure psoriasis, the current goal is to relieve symptoms as longer as possible with a good benefit/risk ratio. That is one of the principal limits of conventional antipsoriatic drugs. New formulations based on nanoencapsulation are a promising opportunity to answer to this limit by offering an optimization of the conventional antipsoriatic drug use (higher activity, lower side effects and frequency of application, etc.). Herein, we tried to put in perspective the mechanistic insights (histological and immunological views) proposed into scientific literature these last years in order to have a better comprehension of psoriasis physiopathology resulting in skin lesions and PsA. The therapeutic armamentarium and the different strategies in the management of psoriasis are discussed in greater details. To finish, the field of encapsulation in nanoparticles is broached in order to put forward recent advances in innovative skin drug delivery systems (ISDDSs) of antipsoriatic active agents for a better efficacy, safety and compliance.

Abstract
BACKGROUND Prediction of response to ultraviolet B (UVB) phototherapy in psoriatic patients mainly relies on clinical criteria, although some genetic predictors have been identified. Toll-like receptors (TLRs) have been involved in psoriasis pathogenesis through activation of the innate immune system. Their polymorphisms may condition not only the clinical profile of psoriasis but also the response to therapy. METHODS We analyzed the role of functional single-nucleotide polymorphisms (SNPs) of TLR2, 5, 4, and 9 in clinical response to a standard narrow-band UVB (NBUVB) therapy in 39 patients with moderate to severe psoriasis. RESULTS We found a significant relationship between TLR9-1486T/C SNP variants and a better response to NBUVB phototherapy. Patients with TC and CC genotype showed a higher improvement of Psoriasis Area and Severity Index (PASI) than patients with TT genotype. Results of multivariate analysis indicate that the differences in PASI improvement at the end of phototherapy attributed to TRL9 SNP genotype were not dependent on the patients' phototype, age, gender, body mass index, basal PASI, or disease evolution. CONCLUSIONS We describe a functional genetic variant in TLR9 gene that might affect the susceptibility to antipsoriatic treatment. The search of genetic predictive factors may be helpful in therapy selection and optimization of therapeutic regimes in psoriatic patients.

Abstract
BACKGROUND Psoriasis is associated with high treatment costs due to the increasing use of biologic drugs. Phototherapy has been demonstrated to be safe and cost effective for the treatment of psoriasis, although it is limited by the requirement for patients to visit a hospital various times a week. OBJECTIVES To evaluate the efficiency of home-based phototherapy with narrow-band UV-B radiation compared with biologic drugs for the treatment of moderate to severe psoriasis under normal practice conditions in our setting. METHODS A retrospective cost-effectiveness study was undertaken in 12 patients with moderate to severe psoriasis. Half of the patients were treated with biologic drugs (2 with etanercept, 2 with adalimumab, and 2 with infliximab) and the other half with home-based phototherapy using a Waldmann UV100L-TL01 lamp. Clinical effectiveness was determined on the basis of achieving a 75% improvement in Psoriasis Area and Severity Index (PASI 75) within 16 weeks of treatment. RESULTS Treatment was considered to be effective in 5 out of 6 patients (83%) treated with biologics and 4 out of 6 patients (66%) treated with home-based phototherapy. The direct costs required to achieve PASI 75 were 8256€ per patient for biologics and 903€ per patient for home-based phototherapy. The costs associated with effective treatment using biologic drugs in a single patient would provide effective home-based phototherapy for 9.1 patients. LIMITATIONS The study included a limited number of patients analyzed over a short time period (16 weeks) and the comparison group included multiple treatments with different predicted responses. CONCLUSIONS Although biologic drugs exhibited greater efficacy, home-based phototherapy was more efficient for the treatment of moderate to severe psoriasis. Home-based phototherapy represents a cost-effective treatment option for patients with psoriasis and may be appropriate for use in the Spanish health care system.
