Abstract
BACKGROUND Increased Staphylococcus aureus (SA) colonization is considered an important factor in the pathogenesis of atopic dermatitis (AD). Antibacterial therapeutic clothing aims to reduce SA colonization and AD inflammation; however, its role in the management of AD remains poorly understood. OBJECTIVES To investigate the effectiveness of antibacterial therapeutic clothing + standard topical treatment in patients with moderate-to-severe AD vs. standard therapeutic clothing + standard topical treatment; and, if effectiveness was demonstrated, to demonstrate its cost-effectiveness. METHODS A pragmatic double-blinded multicentre randomized controlled trial (NCT04297215) was conducted in patients of all ages with moderate-to-severe AD. Patients were centrally randomized 1 : 1 : 1 to receive standard therapeutic clothing or antibacterial clothing based on chitosan or silver. The primary outcome was the between-group difference in Eczema Area and Severity Index (EASI) measured over 52 weeks. Secondary outcomes included patient-reported outcomes (PROs), topical corticosteroid (TCS) use, SA colonization, safety and cost-effectiveness. Outcomes were assessed by means of (generalized) linear mixed-model analyses. RESULTS Between 16 March 2020 and 20 December 2021, 171 patients were enrolled. In total, 159 patients were included (54 in the standard therapeutic clothing group, 50 in the chitosan group and 55 in the silver group). Adherence was high [median 7 nights a week wear (interquartile range 3-7)]. Median EASI scores at baseline and at 4, 12, 26 and 52 weeks were 11.8, 4.3, 4.6, 4.2 and 3.6, respectively, in the standard therapeutic clothing group vs. 11.3, 5.0, 3.0, 3.0 and 4.4, respectively, in the chitosan group, and 11.6, 5.0, 5.4, 4.6 and 5.8, respectively, in the silver group. No differences in EASI over 52 weeks between the standard therapeutic clothing group, the chitosan group [-0.1, 95% confidence interval (CI) -0.3 to 0.2; P = 0.53] or the silver group (-0.1, 95% CI -0.3 to 0.2; P = 0.58) were found. However, a small significant group × time interaction effect between the standard and silver groups was found (P = 0.03), in which the silver group performed worse after 26 weeks. No differences between groups were found in PROs, TCS use, SA skin colonization and healthcare utilization. No severe adverse events or silver absorption were observed. CONCLUSIONS The results of this study suggest no additional benefits of antibacterial agents in therapeutic clothing in patients with moderate-to-severe AD.

Abstract
Silk fibroin has become a prominent material in tissue engineering (TE) over the last 20 years with almost 10,000 published works spanning in all the TE applications, from skeleton to neuronal regeneration. Fibroin is an extremely versatile biopolymer that, due to its ease of processing, has enabled the development of an entire plethora of materials whose properties and architectures can be tailored to suit target applications. Although the research and development of fibroin TE materials and devices is mature, apart from sutures, only a few medical products made of fibroin are used in the clinical routines. <40 clinical trials of Bombyx mori silk-related products have been reported by the FDA and few of them resulted in a commercialized device. In this review, after explaining the structure and properties of silk fibroin, we provide an overview of both fibroin constructs existing in the literature and fibroin devices used in clinic. Through the comparison of these two categories, we identified the burning issues faced by fibroin products during their translation to the market. Two main aspects will be considered. The first is the standardization of production processes, which leads both to the standardization of the characteristics of the issued device and the correct assessment of its failure. The second is the FDA regulations, which allow new devices to be marketed through the 510(k) clearance by demonstrating their equivalence to a commercialized medical product. The history of some fibroin medical devices will be taken as a case study. Finally, we will outline a roadmap outlining what actions we believe are needed to bring fibroin products to the market.

Abstract
Preterm infants, due to immature and dysfunctional skin, have increased water loss through the skin and consequently a decreased body temperature. In order to develop protective garments for preterm infants, it is important to select materials that will protect the child against water and heat loss. The authors are currently involved in the development of protective garments for premature babies, which are similar to baby clothes and contain a membrane that is partially permeable for vapor in combination with textile materials. This article presents the study of materials intended for the production of protective garments for pre-term infants. Samples of materials were investigated to determine biophysical comfort (tests of heat resistance, vapor resistance according to PN-EN ISO 11092:2014-11 and air permeability according to PN-EN ISO 9237) and porosity, surface mass in accordance with PN-EN 12127, and thickness in accordance with PN-EN ISO 5084. In order to determine the porosity of materials and to visualize the structure, tests on computer microtomography were carried out. The mechanical properties of the tested materials and the evaluation of the total hand value were characterized; the samples were tested on the KES device. The aim of this study was to select the most suitable fabrics for protective garments for premature infants to prevent excessive heat and moisture loss from the body, which can lead to hypothermia. For laminates, the optimal results of vapor resistance and heat resistance were obtained for laminate (15 g·m−2 PE foil + 15 g·m−2 PP non-woven), with a level of thermal resistance of 0.0766 m2·K·W−1 and vapor resistance of 188.729 m2·Pa·W−1, and for laminate (15 g·m−2 PE foil + 10 g·m−2 PP non-woven), with a level of thermal resistance of 0.0683 m2·K·W−1 and vapor resistance of 164.085 m2·Pa·W−1. For knitted fabrics, knitwear single cotton 155 g·m−2 showed the highest thermal resistance (0.0296 m2·K·W−1), and knitwear interlock polyester 120 g·m−2 showed the lowest thermal resistance (0.0179 m2·K·W−1). Knitwear cotton 120 g·m−2 had the highest water vapor resistance (8.402 m2·Pa·W−1), while knitwear interlock polyester 130 g·m−2 sample had the lowest resistance (6.356 m2·Pa·W−1). Garments for premature babies should have moisture barrier properties and high thermal insulation. They should also be characterized by optimal air permeability properties. Sample two-layer laminate (15 g·m−2 PE foil + 15 g·m−2 PP non-woven) had the best vapor resistance and thermal insulation properties. Moreover, this sample was characterized by good air permeability and surface weight compared to the other laminate samples. During the design of garments for premature babies, it is important to reduce the surface weight to as low as possible. Among the knitted fabrics, a knitwear single cotton 120 g·m−2 knitwear polyester interlock 120 g·m−2 was selected for having the best THV or tactile comfort. In addition, these knits were chosen for their lower surface weight. Based on the conducted tests, two-layer laminate (15 g·m−2 PE foil + 15 g·m−2 PP non-woven), the knitwear single cotton 120 g·m−2, and knitwear polyester interlock 120 g·m−2 were selected for further research.

Abstract
Currently, there are a few detailed guidelines on the overall management of children and adolescents with moderate-severe atopic dermatitis. AD is a complex disease presenting with different clinical phenotypes, which require an individualized and multidisciplinary approach. Therefore, appropriate interaction between primary care pediatricians, pediatric allergists, and pediatric dermatologists is crucial to finding the best management strategy. In this manuscript, members of the Italian Society of Pediatric Allergology and Immunology (SIAIP), the Italian Society of Pediatric Dermatology (SIDerP), and the Italian Society of Pediatrics (SIP) with expertise in the management of moderate-severe atopic dermatitis have reviewed the latest scientific evidence in the field. This narrative review aims to define a pathway to appropriately managing children and adolescents with moderate-severe atopic dermatitis.

Abstract
Shoe dermatitis is a type of contact dermatitis precipitated by allergens or irritants found in shoes. Potassium dichromate, commonly used in leather processing, is one of the most prevalent agents responsible for shoe dermatitis; however, it is not the only one. Shoe dermatitis caused by an allergen or an irritant may affect a person of any age, sex, or ethnicity. Numerous treatments exist for shoe dermatitis, the most simple yet important being avoidance of causative agents. Pharmaceutical agents commonly used are emollients, humectants, and topical corticosteroids. In more severe cases, topical calcineurin inhibitors and phototherapy may be used.

Abstract
BACKGROUND Clothing fabrics interact closely with the skin to shape our cutaneous microenvironment. Cotton and silk have been traditionally recommended for patients with atopic dermatitis because of reported patient comfort. New synthetic fabrics combine anti-microbial, anti-inflammatory, moisture-wicking, and soothing properties that may augment conventional management strategies in atopic patients. OBJECTIVE We review existing and emerging evidence for fabric selection in patients with atopic dermatitis including cotton, wool, lyocell, silk, anionic, cellulosic/cellulose based, zinc oxide coated, citric acid coated, chitosan coated, silver coated, borage seed oil coated, ethylene vinyl, and polyurethane and offer practical suggestions for clothing and bedding choices. METHODS A systematic search was conducted on PubMed and EMBASE electronic databases for articles from 1 January, 1994 to 1 January, 2020. Studies were included based on the following inclusion criteria: clinical trial, published in English, and fabric as the main agent being evaluated. Case reports, case series, conference abstracts, reviews, animal studies, and duplicates were excluded. Studies were then manually screened by title, abstract, and full-text articles and selected to specifically describe the effects of fabrics in patients with atopic dermatitis. Both adult and pediatric patient studies were included. RESULTS There appears to be an advantage to modern fabric manufacturing and processing techniques that have created smaller diameter, smoother fibers such as super- and ultrafine merino wool and anti-microbial finishes. Traditional cotton and silk fabrics have mixed evidence in improving atopic dermatitis symptoms and severity but have shown to be generally safe. Large-diameter wool has been shown to induce itching and irritation; ultra- or superfine merino wool is non-pruritic and may be recommended as an alternative. Emerging fabrics with potential efficacy in reducing atopic dermatitis severity and Staphylococcus aureus burden include silver-coated, chitosan-coated, and cellulose-based fabrics. Zinc oxide-coated, acid-coated, polyurethane-coated, borage seed oil-coated, anionic, lyocell, and ethylene vinyl fabrics have sparse evidence and require further study before conclusions can be made. CONCLUSIONS Appropriate fabric selection can reduce the symptom severity and exacerbations of atopic dermatitis.

Abstract
Silk biomaterials are known for biomedical and tissue engineering applications including drug delivery and implantable devices owing to their biocompatible and a wide range of ideal physico-chemical properties. Herein, we present a critical overview of the progress of silk-based matrices in skin regeneration therapeutics with an emphasis on recent innovations and scientific findings. Beginning with a brief description of numerous varieties of silks, the review summarizes our current understanding of the biological properties of silk that help in the wound healing process. Various silk varieties such as silkworm silk fibroin, silk sericin, native spider silk and recombinant silk materials have been explored for cutaneous wound healing applications from the past few decades. With an aim to harness the regenerative properties of silk, numerous strategies have been applied to develop functional bioactive wound dressings and viable bio-artificial skin grafts in recent times. The review examines multiple inherent properties of silk that aid in the critical events of the healing process such as cell migration, cell proliferation, angiogenesis, and re-epithelialization. A detailed insight into the progress of silk-based cellular skin grafts is also provided that discusses various co-culture strategies and development of bilayer and tri-layer human skin equivalent under in vitro conditions. In addition, functionalized silk matrices loaded with bioactive molecules and antibacterial compounds are discussed, which have shown great potential in treating hard-to-heal wounds. Finally, clinical studies performed using silk-based translational products are reviewed that validate their regenerative properties and future applications in this area. STATEMENT OF SIGNIFICANCE: The review article discusses the recent advances in silk-based technologies for wound healing applications, covering various types of silk biomaterials and their properties suitable for wound repair and regeneration. The article demonstrates the progress of silk-based matrices with an update on the patented technologies and clinical advancements over the years. The rationale behind this review is to highlight numerous properties of silk biomaterials that aid in all the critical events of the wound healing process towards skin regeneration. Functionalization strategies to fabricate silk dressings containing bioactive molecules and antimicrobial compounds for drug delivery to the wound bed are discussed. In addition, a separate section describes the approaches taken to generate living human skin equivalent that have recently contributed in the field of skin tissue engineering.

Abstract
Humans have long appreciated silk for its lustrous appeal and remarkable physical properties, yet as the mysteries of silk are unraveled, it becomes clear that this outstanding biopolymer is more than a high-tech fiber. This progress report provides a critical but detailed insight into the biomedical use of silk. This journey begins with a historical perspective of silk and its uses, including the long-standing desire to reverse engineer silk. Selected silk structure-function relationships are then examined to appreciate past and current silk challenges. From this, biocompatibility and biodegradation are reviewed with a specific focus of silk performance in humans. The current clinical uses of silk (e.g., sutures, surgical meshes, and fabrics) are discussed, as well as clinical trials (e.g., wound healing, tissue engineering) and emerging biomedical applications of silk across selected formats, such as silk solution, films, scaffolds, electrospun materials, hydrogels, and particles. The journey finishes with a look at the roadmap of next-generation recombinant silks, especially the development pipeline of this new industry for clinical use.

Abstract
BACKGROUND Antibacterial clothes are classified as a complementary treatment in line with antisepsis, although meta-studies are unable to find significant improvements of eczemas. METHODS The antibacterial effectiveness of conventional AD clothes was compared across each other by (i) standard suspension tests for the appraisal of antibacterial products and (ii) a real-life setup of affected AD skin using S. aureus colonised artificial skin, to assess if functional clothes are effective under practical wear conditions. Additionally, the interaction of the fibre types with a moisturising cream was evaluated during a real wearing situation and after domestic laundry. RESULTS In the real-life setup simulating dry skin microenvironment, all samples failed to reduce S. aureus. Silver and zinc-fabrics showed a slight activity only under unrealistic moist conditions. When using standard suspension tests, samples differed considerably in their antibacterial effectiveness, where silver and zinc endowed fibres outperformed AEGIS endowed silk fabrics. Garments absorbed the cream dependent on the particular fibre types. Furthermore, domestic laundry was unable to completely remove the cream. CONCLUSION Considerable differences in the antibacterial effectiveness of conventional AD clothes were revealed. Under practical (dry) wear conditions, garments were unable to modify skin colonization with S. aureus, although effectiveness can be triggered by wetting the garments. Remnants of moisturising cream remain on the fibres after laundry.

Abstract
Silk possesses many beneficial wound healing properties, and electrospun scaffolds are especially applicable for skin applications, due to their smaller interstices and higher surface areas. However, purified silk promotes microbial growth. Selenium nanoparticles have shown excellent antibacterial properties and are a novel antimicrobial chemistry. Here, electrospun silk scaffolds were doped with selenium nanoparticles to impart antibacterial properties to the silk scaffolds. Results showed significantly improved bacterial inhibition and mild improvement in human dermal fibroblast metabolic activity. These results suggest that the addition of selenium nanoparticles to electrospun silk is a promising approach to improve wound healing with reduced infection, without relying on antibiotics.

Abstract
The Italian Consensus Conference on clinical management of atopic dermatitis in children reflects the best and most recent scientific evidence, with the aim to provide specialists with a useful tool for managing this common, but complex clinical condition. Thanks to the contribution of experts in the field and members of the Italian Society of Pediatric Allergology and Immunology (SIAIP) and the Italian Society of Pediatric Dermatology (SIDerP), this Consensus statement integrates the basic principles of the most recent guidelines for the management of atopic dermatitis to facilitate a practical approach to the disease. The therapeutical approach should be adapted to the clinical severity and requires a tailored strategy to ensure good compliance by children and their parents. In this Consensus, levels and models of intervention are also enriched by the Italian experience to facilitate a practical approach to the disease.

Abstract
Atopic dermatitis, perhaps more than other dermatologic diseases, has garnered much attention in the realm of alternative medicine. This may be because its etiopathogenesis is incompletely understood, it is increasingly common, and it waxes and wanes often without clear precipitants, opening up many opportunities for misinterpretation. Herein we explore the evidence for a number of different alternative and complementary therapies, from textiles to vitamin supplements. By definition, none have enough data to be deemed "effective" in a conventional sense, but it is hopeful that some show promising evidence that may one day lead to mainstream acceptance with further research.

Abstract
Biomedical textiles and fiber-based implants (BTFIs) have been in routine clinical use to facilitate healing for nearly five decades. Amongst the variety of biomaterials used, silk-based biomaterials (SBBs) have been widely used clinically viz. sutures for centuries and are being increasingly recognized as a prospective material for biomedical textiles. The ease of processing, controllable degradability, remarkable mechanical properties and biocompatibility have prompted the use of SBBs for various BTFIs for extracorporeal implants, soft tissue repair, healthcare/hygiene products and related needs. The present Review focuses on BTFIs from the perspective of types and physical and biological properties, and this discussion is followed with an examination of the advantages and limitations of BTFIs from SBBs. The Review covers progress in surface coatings, physical and chemical modifications of SBBs for BTFIs and identifies future needs and opportunities for the further development for BTFIs using SBBs.

Abstract
This study surveys the improvement characteristics in old-aged muscular mitochondria by bio-active materials coated fabric (BMCF). To observe the effects, the fabric (10 and 30%) was worn to old-aged rat then the oxygen consumption efficiency and copy numbers of mitochondria, and mRNA expression of apoptosis- and mitophagy-related genes were verified. By wearing the BMCF, the oxidative respiration significantly increased when using the 30% materials coated fabric. The mitochondrial DNA copy number significantly decreased and subsequently recovered in a dose-dependent manner. The respiratory control ratio to mitochondrial DNA copy number showed a dose-dependent increment. As times passed, Bax, caspase 9, PGC-1α and β-actin increased, and Bcl-2 decreased in a dose-dependent manner. However, the BMCF can be seen to have had no effect on Fas receptor. PINK1 expression did not change considerably and was inclined to decrease in control group, but the expression was down-regulated then subsequently increased with the use of the BMCF in a dose-dependent manner. Caspase 3 increased and subsequently decreased in a dose-dependent manner. These results suggest that the BMCF invigorates mitophagy and improves mitochondrial oxidative respiration in skeletal muscle, and in early stage of apoptosis induced by the BMCF is not related to extrinsic death-receptor mediated but mitochondria-mediated signaling pathway.

Abstract
Naju Jjok (Polygonum tinctorium Lour.) has been known to treat skin diseases in traditional Korean medicine. A natural textile dye, Niram made from Naju Jjok has traditionally been used to dye clothes. Thymic stromal lymphopoietin (TSLP) plays an important role in the development of atopic dermatitis (AD). Thus, we investigated that Niram might ameliorate AD through regulation of TSLP. Niram significantly inhibited the levels of TSLP through blockade of caspase-1/receptor-interacting protein 2 pathway in stimulated mast cells. Further, Niram ameliorated clinical symptoms in AD mouse. Niram significantly inhibited the infiltration of inflammatory cells in lesional skin. The levels of TSLP, caspase-1, IL-4, and IL-6 were inhibited in lesional skin applied topically with Niram. Niram significantly inhibited the serum levels of IgE and histamine in AD mouse. Finally, Niram significantly inhibited the levels of TSLP in polyriboinosinic polyribocytidylic acid-stimulated human keratinocyte HaCaT cells. These results establish Niram as a functional dye embracing the aspects of not only a traditional use but also a pharmacological effect.

Abstract
Nanotechnology and tissue engineering have enabled engineering of nanostructured strategies to meet the current challenges in skin tissue regeneration. Electrospinning technology creates porous nanofibrous scaffolds to mimic extracellular matrix of the native tissues. The present study was performed to gain some insights into the applications of poly(l-lactic acid)-co-poly-(ε-caprolactone) (PLACL)/silk fibroin (SF)/vitamin E (VE)/curcumin (Cur) nanofibrous scaffolds and to assess their potential for being used as substrates for the culture of human dermal fibroblasts for skin tissue engineering. PLACL/SF/VE/Cur nanofibrous scaffolds were fabricated by electrospinning and characterized by fiber morphology, membrane porosity, wettability, mechanical strength, and chemical properties by Fourier transform infrared (FTIR) analysis. Human dermal fibroblasts were cultured on these scaffolds, and the cell scaffold interactions were analyzed by cell proliferation, cell morphology, secretion of collagen, expression of F-actin, and 5-chloromethylfluorescein diacetate (CMFDA) dye. The electrospun nanofiber diameter was obtained between 198±4 nm and 332±13 nm for PLACL, PLACL/SF, PLACL/SF/VE, and PLACL/SF/VE/Cur nanofibrous scaffolds. FTIR analysis showed the presence of the amide groups I, II, and III, and a porosity of up to 92% obtained on these nanofibrous scaffolds. The results showed that the fibroblast proliferation, cell morphology, F-actin, CMFDA dye expression, and secretion of collagen were significantly increased in PLACL/SF/VE/Cur when compared to PLACL nanofibrous scaffolds. The accessibility of human dermal fibroblasts cultured on PLACL/SF/VE/Cur nanofibrous scaffolds proved to be a potential scaffold for skin tissue regeneration.

Abstract
Atopic dermatitis (AD) continues to present significant therapeutic challenges, especially in severe cases. Navigating the line between risk and benefit can be difficult for more powerful medications such as immunosuppressants, but non-pharmacologic treatments are often overlooked and underutilized. Creative application of these more physical therapies can serve to minimize the pharmacologic treatments and their side effects, and possibly even create synergy between modalities, to maximize benefit to the patient.

Abstract
Atopic dermatitis (AD) is a relapsing inflammatory skin disease with a considerable social and economic burden. Functional textiles may have antimicrobial and antipruritic properties and have been used as complementary treatment in AD. We aimed to assess their effectiveness and safety in this setting. We carried out a systematic review of three large biomedical databases. GRADE approach was used to rate the levels of evidence and grade of recommendation. Meta-analyses of comparable studies were carried out. Thirteen studies (eight randomized controlled trials and five observational studies) met the eligibility criteria. Interventions were limited to silk (six studies), silver-coated cotton (five studies), borage oil, and ethylene vinyl alcohol (EVOH) fiber (one study each). Silver textiles were associated with improvement in SCORAD (2 of 4), fewer symptoms, a lower need for rescue medication (1 of 2), no difference in quality of life, decreased Staphyloccosus aureus colonization (2 of 3), and improvement of trans-epidermal water loss (1 of 2), with no safety concerns. Silk textile use was associated with improvement in SCORAD and symptoms (2 of 4), with no differences in quality of life or need for rescue medication. With borage oil use only skin erythema showed improvement, and with EVOH fiber, an improvement in eczema severity was reported. Recommendation for the use of functional textiles in AD treatment is weak, supported by low quality of evidence regarding effectiveness in AD symptoms and severity, with no evidence of hazardous consequences with their use. More studies with better methodology and longer follow-up are needed.

Abstract
BACKGROUND Atopic dermatitis (AD) is a disease with multifactorial etiology. Staphylococcus aureus is one of the predominant environmental factors acting on the course and intensity of the disease. OBJECTIVES The aims of the study were to evaluate the efficacy and safety of clothing made of cellulose fibers with seaweed enriched with silver ions in the treatment of children with AD. METHODS A prospective, randomized and double-blinded controlled selection was done to recruit 19 children with diagnosis of AD. This sample was divided in two groups with similar demographic and clinical characteristics (the "control" group of seven children who wore placebo clothing and the "trial textile" group of 12 children who wore clothing with the new textile). The severity of AD and clinical response were assessed by the SCORAD index, the intensity of pruritus and the changes in sleep characteristics, at the start of the study and after 7 and 90 d. RESULTS The SCORAD index improvement in the group with the fiber under study was statistically significant after the first 7 d of treatment (p < 0.001) and was reduced by about 45% after 90 d. There was also a statistically relevant reduction of the intensity of pruritus and an improvement in the sleep quality after the initial 7 d and at day 90. CONCLUSION The results showed that the textile clothing with seaweed enriched with silver ions brings a quicker improvement of the patients in the first days in opposition to the use of standard all-cotton clothes. The results also reinforce the importance of non-pharmacological measures, like clothing, in the management of patients with a diagnosis of AD.

Abstract
In the present study, we reported fabrication and skin benefit of a novel vitamin E (VE)-loaded silk fibroin (SF) nanofibrous mats. RRR-α-Tocopherol polyethylene glycol 1000 succinate (VE TPGS), a water-soluble derivative of VE, was incorporated into SF nanofiber successfully by aqua solution electrospinning for the first time. Morphology of the composite nanofibers changed with the different amount of VE TPGS: a ribbon-like shape for lower loading dose of VE TPGS, while a round shape for higher loading dose (more than 4% (wt/wt) based on the weight of SF). After treated with 75% (v/v) ethanol vapor, the composite nanofibrous mats showed an excellent water-resistant ability. In vitro study disclosed a sustained release behavior of VE TPGS disassociated from the nanofibrous mats. The mouse skin fibroblasts (L929 cells) cultured on the VE-loaded SF nanofibrous mats spread and proliferated much better than on cover slips. Moreover, the incorporation of VE TPGS was found strengthening the ability of SF nanofibrous mats on protecting the cells against oxidation stress induced by tert-butyl hydroperoxide. Our data presented impressive skin benefits of this VE-loaded SF nanofibrous mats, suggesting a promising applicative potential of this novel product on personal skin care, tissue regeneration and other related area.

Abstract
The existing evidence for treatment of atopic eczema (atopic dermatitis, AE) is evaluated using the national standard Appraisal of Guidelines Research and Evaluation. The consensus process consisted of a nominal group process and a DELPHI procedure. Management of AE must consider the individual symptomatic variability of the disease. Basic therapy is focused on hydrating topical treatment, and avoidance of specific and unspecific provocation factors. Anti-inflammatory treatment based on topical glucocorticosteroids and topical calcineurin inhibitors (TCI) is used for exacerbation management and more recently for proactive therapy in selected cases. Topical corticosteroids remain the mainstay of therapy, but the TCI tacrolimus and pimecrolimus are preferred in certain locations. Systemic immune-suppressive treatment is an option for severe refractory cases. Microbial colonization and superinfection may induce disease exacerbation and can justify additional antimicrobial treatment. Adjuvant therapy includes UV irradiation preferably with UVA1 wavelength or UVB 311 nm. Dietary recommendations should be specific and given only in diagnosed individual food allergy. Allergen-specific immunotherapy to aeroallergens may be useful in selected cases. Stress-induced exacerbations may make psychosomatic counselling recommendable. 'Eczema school' educational programs have been proven to be helpful. Pruritus is targeted with the majority of the recommended therapies, but some patients need additional antipruritic therapies.

Abstract
BACKGROUND Several previous studies have suggested the improvement of atopic dermatitis (AD) in response to special fabrics. In particular, beneficial effects have been reported, following the use of anion textiles. OBJECTIVE The purpose of this study is to evaluate the effectiveness and safety of an anion textile in patients suffering from AD. METHODS We compared an anion textile with a pure cotton textile. Fifty-two atopic patients (n=52) were enrolled and divided into two groups. The patients in the test (n=25) and control (n=19) groups wore undergarments made of an anion textile or pure cotton over a period of 4 weeks. The overall severity of disease was evaluated using the SCORing atopic dermatitis (SCORAD) index, whereas, the treatment efficacy was measured using a Tewameter® (Courage & Khazaka, Cologne, Germany), Mexameter® (Courage & Khazaka) and Corneo meter® (Courage & Khazaka). RESULTS At the end of the study, a significant decrease in the SCORAD index was observed among the patients with AD in the test group (mean SCORAD decreased from 47.2 to 36.1). Similarly, improvements in the mean transepidermal water loss, skin erythema and stratum corneum hydration were significantly greater among the patients with AD in the test group than in the control group. CONCLUSION Anion textiles may be used to significantly improve the objective and subjective symptoms of AD, and are similar in terms of comfort to cotton textiles. The use of anion textiles may be beneficial in the management of patients with AD.

Abstract
Despite the generally excellent results achieved with fluconazole 150 mg weekly in recurrent vulvovaginal candidosis (RVVC), some patients with a long history of disease do not achieve complete resolution of symptoms following antimycotic treatment. It is thought that use of tight synthetic fabric underwear could be a significant factor in causing recurrence. We decided to compare underwear made of Dermasilk®, a pure fibroin fabric impregnated with a permanent antimicrobial protection, with a cotton placebo to see whether it could be a useful adjunctive tool in the management of RVVC. We recruited 96 women who had a long-term history of RVVC and had not responded to oral antimycotics with complete satisfaction. The patients were randomly divided into two groups and instructed to use either white cotton placebo briefs or Dermasilk® briefs. Both groups were treated with fluconazole 150 mg once weekly for 6 months. After 6 months, the Dermasilk group showed a statistically significant greater decrease of itching, burning, erythema and a smaller number of recurrences than the cotton group. Our work suggests that Dermasilk® briefs could be a useful adjunctive tool in addition to antimycotic treatment to help relieve the discomfort of recurrent vulvovaginitis.

Abstract
Atopic dermatitis (AD) is easily aggravated by detergents, synthetic and woollen clothing, and bacterial colonization. Cotton clothing is often recommended for children with AD, but cotton can contain rough fibres that may act as skin irritants. In contrast, silk is characterized by smooth fibres with minimal potential for irritation. We report a sericin-free silk (DermaSilk), which is treated with AEGIS AEM5772/5, a product that has antibacterial properties, and evaluate its use in the treatment of AD.

Abstract
Eczema, frequently named atopic dermatitis, is the most frequent chronic skin disease of early childhood, with a high prevalence in industrialized countries and a relapsing-remitting course that is responsible for a serious burden on affected children and their families. Even though most facets of this disease are nowadays well known and numerous guidelines are available, some confusion still exists regarding certain aspects. First, several names have been proposed for the disorder. We suggest that the name and definition adopted by the World Allergy Organization should be used: 'eczema,' divided into 'atopic,' when an allergic sensitization can be demonstrated, and 'non-atopic,' in the absence of sensitization. Several diagnostic criteria have been proposed, but at present the two most reliable are the 2003 revision by the American Academy of Dermatology of the Hanifin-Rajka criteria, and those by Williams revised in 2005. To date, 20 different clinical scores have been published to assess the severity; however, only the EASI (Eczema Area and Severity Index), the SCORAD (SCORing Atopic Dermatitis), and the POEM (Patient-Oriented Eczema Measure) seem to have been adequately validated and are recommended for use in clinical practice and trials. The diagnostic tests to identify associated allergy or sensitization include skin-prick tests, determination of the specific IgE in serum using different assays, and atopy patch tests; in the case of suspected food allergy, a food challenge may be necessary to define the diagnosis. To evaluate quality of life, tools exist that allow both the child's and family's impairment to be considered. In addition, several algorithms exist to help decide therapy on a step-wise basis. However, such guidelines and algorithms represent only an aid to the physician and not an obligatory directive, since the ultimate judgment regarding any therapy must be performed by the physician and tailored to individual needs. A clear and validated definition of eczema control would permit better monitoring of the disease, similar to the situation with asthma in recent years. Finally, the review examines the role of special textiles in diminishing Staphylococcus aureus skin superinfection, of house dust-mite avoidance measures, and of educational programs for patients and their families, which may all help improve eczema.

Abstract
Atopic dermatitis (AD) is the most common chronic inflammatory skin disease, affecting 10-20% of children and 2% of adults worldwide. Preventive treatment of AD consists of daily skin hydration and emollient therapy; but the majority of patients still require symptomatic treatment with topical corticosteroids and/or topical calcineurin inhibitors, both of which may be associated with potential long-term side effects. With increasing evidence supporting the role of skin barrier defects in the pathogenesis of AD, there is also a parallel increase in medications that claim to assist barrier repair. The current review discusses some exciting results with these medications, as well as the challenges that lie ahead of them. While barrier repair treatments offer some promise, there continues to be a need for safer anti-inflammatory medications. Some of these medications under investigation are phosphodiesterase-4 inhibitors, urocanic acid oxidation products and IL-4/IL-13 receptor blockers. The review also discusses anti-staphylococcal treatments including nanocrystalline silver cream, silver and antimicrobial-coated fabrics, and anti-itch treatments including mu-opiod receptor antagonists, chymase inhibitors and cannabinoid receptor agonists. These medications may become an integral part of AD therapy.

Abstract
Symptoms of atopic dermatitis are often affected by environmental irritants. Modulation of potential irritants may benefit such symptoms. The purpose of this study was to evaluate the impact of a novel silklike bedding fabric for persons with mild to moderate atopic dermatitis. Participants with mild to moderate atopic dermatitis were provided a bedsheet set. Eczema Area and Severity Index and Investigator Global Assessment were the primary outcome measures. Visual Analog Scale for itch and a quality of life were also evaluated. The Wilcoxon signed rank test indicated a significant decrease in severity, with the Investigator Global Assessment score decreasing from 2.05 to 1.74 at week 8 (p = 0.03), the Eczema Area and Severity Index decreasing from 2.63 at baseline to 2.19 (p = 0.014), and the itching score decreasing from 3.97 to 3.00 (p = 0.010). An increase in the study-specific quality of life index was also observed, changing from -0.08 (no change in quality of life) to 1.23 (some improvement) (p < 0.0001). Atopic dermatitis is commonly recalcitrant to therapy and synthetic silklike bed linens may have value as another option for the treatment of this disease. This pilot study demonstrated promising results that warrant confirmation in controlled clinical studies.

Abstract
BACKGROUND A randomized, double-blind study designed to compare the efficacy of DermaSilk versus a sleeve of similar structure but minus the AEM 5772/5 antimicrobial finish in the treatment of atopic dermatitis (AD). OBJECTIVE To evaluate the clinical effect of adding an antimicrobial finish to knitted silk garments on eczema severity and on pruritus in patients with AD. METHODS Thirty patients aged between 3 and 31 years (mean 14.2 +/- 7.7) were enrolled. The inclusion criterion was that the patients presented with active AD with eczematous lesions located on the arms without any sign of infection. Each participant was given a set of 4 pairs of knitted silk tubular sleeves marked with seams of different colours. Only one colour was treated with AEGIS AEM 5772/5. This information was unknown to both the clinicians and the patients/parents. At baseline (T0) and after 7 (T7), 14 (T14), 21 (T21) and 28 (T28) days, the patients were evaluated using the following methods: photographic assessment, local modified SCORAD index adapted for only the arm, and parent/patient assessment of pruritus measured with a visual analogue scale. RESULTS The mean local SCORAD index of both the DermaSilk- and the unmodified-silk-covered arms decreased significantly between baseline (T0) and the end of study (T28). However, while the Derma-Silk group showed a constant decrease each week, the unmodified-silk group showed a significant decrease only in the first 2 weeks of the study. Also the decrease in pruritus values between T0 and T28 was greater for the DermaSilk group. CONCLUSIONS This study demonstrates the importance of including the AEM 5772/5 finish to the specially knitted silk for a long-term improvement of atopic eczema symptoms.

Abstract
Irritation of the skin of patients with atopic dermatitis by contact with rough fibres of synthetic or woollen clothes is well known. Therefore, it has been recommended that patients should wear cotton clothes. However, cotton also consists of rough fibres able to irritate the skin, whereas silk is characterized by smooth fibres without irritating potential. The aim of our study was to evaluate the clinical effect of Dermasilk- a special silk fabric (sericin-free silk treated with AEGIS AEM5772/5 which has antibacterial properties) - in children with atopic dermatitis. A total of 22 children with mild-to-moderate atopic dermatitis were recruited for a study period of 3 months. All of them received three different tube-fabrics - Dermasilk, sericin-free silk fabric without AEGIS AEM 5772/5 and cotton, covering the cubital region. Patients were advised to wear the Dermasilk fabric all day long during the whole study period on one arm, whereas the sericin-free AEGIS-free silk tube had to be used during the first 2 wk only on the other arm followed by the use of the cotton tube for the rest of the study period. Evaluation of the local SCORAD score was carried out at the beginning of the study, after 2, 4, 8 and 12 wk. A significant reduction of the local SCORAD index of the Dermasilk covered arm was observed after 4, 8 and 12 wk in comparison with the cotton-covered arm score [median (quartile 1-quartile 3)] 6.5 (5-8) vs. 8 (7-9), p < 0.002; 6 (5.25-7.75) vs. 8 (7-9), p < 0.0001; and 6 (5-6) vs. 8 (7.25-10), p < 0.0001. The use of Dermasilk has a significant beneficial effect in atopic dermatitis because of the non-irritating properties of silk as well as the antibacterial capacity of AEGIS AEM 5772/5.

Abstract
There are remarkable differences in the diagnostic and therapeutic management of atopic dermatitis practiced by dermatologists and pediatricians in different countries. Therefore, the European Academy of Allergy and Clinical Immunology and the American Academy of Allergy, Asthma and Immunology nominated expert teams who were given the task of finding a consensus to serve as a guideline for clinical practice in Europe as well as in North America. The consensus report is part of the PRACTALL initiative, which is endorsed by both academies.

Abstract
BACKGROUND Patients with atopic dermatitis (AD) have an increased tendency to develop bacterial skin infections. Colonization with Staphylococcus aureus is known to be a major trigger and might also play a pathophysiological role. Because of their antiseptic action, silver-coated textiles suppress S. aureus colonization and toxin formation, thus damping the inflammatory reaction. OBJECTIVES To evaluate the clinical effectiveness and safety of a special silver textile in the treatment of patients suffering from acute AD. METHODS In a randomized phase II monocenter parallel-group comparative study 30 patients were recruited (average age 25.5 years, min. 4 years, max. 70 years) who were affected by AD in an acute phase. During the first study phase from Day 1 to Day 14, 10 patients received a silver textile (Group 1), 10 a silver-free textile (Group 2), and 10 prednicarbate ointment (Group 3). In the second phase from Day 15 to Day 28 all patients wore the silver textile, and during the follow-up period from Day 28 to Day 56 no textiles were used. Prednicarbate ointment was allowed as emergency medication, but ointment consumption was measured. The overall severity of the disease was evaluated using the SCORAD index as the primary efficacy parameter. Secondary parameters included severity of pruritus and the patients' assessment of their disease control (uncontrolled, limited, good or complete). Safety tests included hematology, blood chemistry, urinalysis for silver, and physical examination for silver deposits in the skin and mucous membranes. RESULTS The initial SCORAD was 61.6 (IQR 26.6, min. 30.6, max. 99.9). At the end of the Study Phase 1 the SCORAD had improved significantly in the patients of Groups 1 (74.6-29.9, p = 0.005) and 3 (57.8-24.0, p = 0.009). During Study Phase 2 healing of eczema continued in Group 1 (SCORAD 29.9-18.1, p = 0.037), was observed in Group 2 (48.2-24.1, p = 0.015), and remained at an improved level in Group 3 (SCORAD 24-23.5). Consumption of prednicarbate ointment (Phase 1, Phase 2, follow-up period, medians are given): Group 1: 135 g, 10 g, 45 g; Group 2: 13 g, 0 g, 0 g; Group 3: 145 g, 30 g, 90 g. Silver textiles reduced the severity of the pruritus (p = 0.031); silver-free textiles (n.s.) and prednicarbate (n.s.) were less effective. No undesired events were observed. CONCLUSION The elastic silver textile worn directly against the skin led to an impressive improvement of AD and a reduction in the use of prednicarbate ointment.
