Abstract
INTRODUCTION Basic therapy is of central importance in the treatment of atopic eczema. Using electron microscopic images, the morphology of epidermal skin barrier and its lipids was investigated after application of a lipid foam cream and basic cream. METHODS Patients with two contralateral comparable atopic eczema (local SCORAD 1-10) on the forearms were tested. Eczema was treated with a lipid foam cream or basic cream twice daily for 28 days. At the beginning, after 14 days and at the end of application, the local SCORAD, transepidermal water loss (TEWL), skin hydration, intercellular lipid length (ICLL) in the intercellular space (ICS) of the stratum corneum (SC) and skin lipids were determined. RESULTS After application of the foam cream, the epidermal skin barrier could be completely restored and corresponded to skin-healthy skin, while the epiderrmal skin barrier could not reach this state after care with the basic cream. The content of lipids in the SC increases significantly by 31% after basic cream treatment, whereas they are significantly increased by 85% after application of the lipid foam cream. The local SCORAD improved for both treatments to about the same extent, no significant results could be shown for TEWL and skin hydration. CONCLUSION In subjects with mild atopic eczema, the lipid foam cream leads to a measurable recovery of the skin barrier which is much more pronounced in comparison to the basic cream.

Abstract
Introduction Medical device repairing emollient creams (MDRECs) are designed to repair and protect the skin barrier. In this study, we examined the added clinical benefit and tolerability of a MDREC when used in association with a moderately potent topical corticosteroid (TCS) for adults with atopic dermatitis (AD). Methods This was an intra-individual randomized controlled trial in adults with moderate to severe AD (EudraCT no. 2014-002,194-10). Symmetrical lesions on each arm of the subjects were randomized to treatment for 10 days with twice-daily TCS (desonide) cream alone or with combined TCS + MDREC. Subjects were then included in a following 2-week maintenance phase if the AD on at least one test area had sufficiently improved so that the treatment was no longer needed. During the maintenance phase, treatment with the TCS cream was stopped, but twice-daily application of the MDREC was continued on the same test area previously assigned to receive it. The primary outcome measure was the change in local Scoring Atopic Dermatitis (SCORAD) index between day 1 and 3 based on investigators’ assessment. Secondary measures of lesion severity included changes in the local patient-oriented SCORAD index, pruritus intensity according to subjects’ assessments, and global assessments by subjects and investigators. Results The study included 54 subjects. The change in investigator-observed local SCORAD index between day 1 and 3 was − 14.4% with TCS alone and − 24.5% for TCS + MDREC (p = 0.0005). Between baseline and the end of the treatment phase, all secondary measures of lesion severity decreased more with the combined TCS + MDREC treatment than with the TCS cream alone. The MDREC also reduced the relapse of AD lesions during the maintenance phase. Tolerability was very good, and the product was well accepted by subjects. Conclusion These results support using the MDREC in association with TCS during AD flares and as a maintenance therapy after treatment with TCS has stopped.

Abstract
Eczema is a chronic inflammatory skin disorder with considerable impact on quality of life. Emollients or moisturizers are widely recommended, but are these effective and safe? We searched for randomized controlled trials (RCTs) in the Cochrane Skin Group Specialised Skin Register, CENTRAL in The Cochrane Library, MEDLINE, Embase, LILACS, the GREAT database and five trial registers to December 2015. We included 77 RCTs with 6603 participants. Seven studies (9%) were at low risk of bias, 34 (44%) had unclear risk and 36 (47%) were at high risk. The quality of the evidence was mainly low or moderate for the prespecified outcomes. The most important comparison, 'moisturizer vs. no moisturizer', showed improved Scoring Atopic Dermatitis values in the moisturizer group compared with no moisturizer [mean difference -2·42, 95% confidence interval (CI) -4·55 to -0·28], but did not meet the minimal important difference of 8·7. Fewer flares were seen (risk ratio 0·40, 95% CI 0·23-0·70) and the rate of flares was reduced (hazard ratio 3·74, 95% CI 1·86-7·50). The groups applying moisturizer used less topical corticosteroids over 6-8 weeks (mean difference -9·30 g, 95% CI 15·3 to -3·27). Glycyrrhetinic acid-, urea- and glycerol-containing creams worked better than their controls (vehicle, placebo or no moisturizer) according to both participants and physicians. More flares were reported with moisturizer alone than when combined with twice-weekly fluticasone propionate (risk ratio 2·17, 95% CI 1·55-3·11). Adding moisturizers to topical anti-inflammatory treatment was more effective than anti-inflammatory treatment alone and resulted in fewer flares.

Abstract
Introduction Moisturizers play a prominent role in the management of atopic dermatitis by improving the impaired skin barrier function and enhancing skin hydration. Their efficacy was evaluated in a recently published Cochrane Review ‘Emollients and moisturizers for eczema’. Objective In the present review, we summarize the performance and safety of Cetaphil® and Excipial® moisturizing products. Methods This review was carried out in compliance with standard Cochrane methodological procedures, which means independent study selection, data extraction, assessment of risk of bias, and analyses by two review authors. The quality of evidence for the predefined outcomes was rated with the GRADE approach. The prespecified outcomes of the review included participant assessments, satisfaction, adverse events, investigator assessments, prevention of flares, change in use of topical active treatment, skin barrier function and quality of life. Results Four randomized controlled studies examining these moisturizers were included in the previously published Cochrane Review. For the performance and tolerability of these moisturizers, there was very low to moderate quality evidence for the prespecified outcomes. Conclusion The results from these four studies are in line with those of the Cochrane Review that moisturizers themselves have beneficial effects, and that combining moisturizers with active topical treatment produced better results when compared to active topical treatment alone.

Abstract
BACKGROUND Eczema is a chronic skin disease characterised by dry skin, intense itching, inflammatory skin lesions, and a considerable impact on quality of life. Moisturisation is an integral part of treatment, but it is unclear if moisturisers are effective. OBJECTIVES To assess the effects of moisturisers for eczema. SEARCH METHODS We searched the following databases to December 2015: Cochrane Skin Specialised Register, CENTRAL, MEDLINE, Embase, LILACS, the GREAT database. We searched five trials registers and checked references of included and excluded studies for further relevant trials. SELECTION CRITERIA Randomised controlled trials in people with eczema. DATA COLLECTION AND ANALYSIS We used standard Cochrane methodological procedures. MAIN RESULTS We included 77 studies (6603 participants, mean age: 18.6 years, mean duration: 6.7 weeks). We assessed 36 studies as at a high risk of bias, 34 at unclear risk, and seven at low risk. Twenty-four studies assessed our primary outcome 'participant-assessed disease severity', 13 assessed 'satisfaction', and 41 assessed 'adverse events'. Secondary outcomes included investigator-assessed disease severity (addressed in 65 studies), skin barrier function (29), flare prevention (16), quality of life (10), and corticosteroid use (eight). Adverse events reporting was limited (smarting, stinging, pruritus, erythema, folliculitis).Six studies evaluated moisturiser versus no moisturiser. 'Participant-assessed disease severity' and 'satisfaction' were not assessed. Moisturiser use yielded lower SCORAD than no moisturiser (three studies, 276 participants, mean difference (MD) -2.42, 95% confidence interval (CI) -4.55 to -0.28), but the minimal important difference (MID) (8.7) was unmet. There were fewer flares with moisturisers (two studies, 87 participants, RR 0.40, 95% CI 0.23 to 0.70), time to flare was prolonged (median: 180 versus 30 days), and less topical corticosteroids were needed (two studies, 222 participants, MD -9.30 g, 95% CI -15.3 to -3.27). There was no statistically significant difference in adverse events (one study, 173 participants, risk ratio (RR) 15.34, 95% CI 0.90 to 261.64). Evidence for these outcomes was low quality.With Atopiclair (three studies), 174/232 participants experienced improvement in participant-assessed disease severity versus 27/158 allocated to vehicle (RR 4.51, 95% CI 2.19 to 9.29). Atopiclair decreased itching (four studies, 396 participants, MD -2.65, 95% CI -4.21 to -1.09) and achieved more frequent satisfaction (two studies, 248 participants, RR 2.14, 95% CI 1.58 to 2.89), fewer flares (three studies, 397 participants, RR 0.18, 95% CI 0.11 to 0.31), and lower EASI (four studies, 426 participants, MD -4.0, 95% CI -5.42 to -2.57), but MID (6.6) was unmet. The number of participants reporting adverse events was not statistically different (four studies, 430 participants, RR 1.03, 95% CI 0.79 to 1.33). Evidence for these outcomes was moderate quality.Participants reported skin improvement more frequently with urea-containing cream than placebo (one study, 129 participants, RR 1.28, 95% CI 1.06 to 1.53; low-quality evidence), with equal satisfaction between the two groups (one study, 38 participants, low-quality evidence). Urea-containing cream improved dryness (investigator-assessed) more frequently (one study, 128 participants, RR 1.40, 95% CI 1.14 to 1.71; moderate-quality evidence) with fewer flares (one study, 44 participants, RR 0.47, 95% CI 0.24 to 0.92; low-quality evidence), but more participants in this group reported adverse events (one study, 129 participants, RR 1.65, 95% CI 1.16 to 2.34; moderate-quality evidence).Three studies assessed glycerol-containing moisturiser versus vehicle or placebo. More participants in the glycerol group noticed skin improvement (one study, 134 participants, RR 1.22, 95% CI 1.01 to 1.48; moderate-quality evidence), and this group saw improved investigator-assessed SCORAD (one study, 249 participants, MD -2.20, 95% CI -3.44 to -0.96; high-quality evidence), but MID was unmet. Participant satisfaction was not addressed. The number of participants reporting adverse events was not statistically significant (two studies, 385 participants, RR 0.90, 95% CI 0.68 to 1.19; moderate-quality evidence).Four studies investigated oat-containing moisturisers versus no treatment or vehicle. No significant differences between groups were reported for participant-assessed disease severity (one study, 50 participants, RR 1.11, 95% CI 0.84 to 1.46; low-quality evidence), satisfaction (one study, 50 participants, RR 1.06, 95% CI 0.74 to 1.52; very low-quality evidence), and investigator-assessed disease severity (three studies, 272 participants, standardised mean difference (SMD) -0.23, 95% CI -0.66 to 0.21; low-quality evidence). In the oat group, there were fewer flares (one study, 43 participants, RR 0.31, 95% CI 0.12 to 0.7; low-quality evidence) and less topical corticosteroids needed (two studies, 222 participants, MD -9.30g, 95% CI 15.3 to -3.27; low-quality evidence), but more adverse events were reported (one study, 173 participants; Peto odds ratio (OR) 7.26, 95% CI 1.76 to 29.92; low-quality evidence).All moisturisers above were compared to placebo, vehicle, or no moisturiser. Participants considered moisturisers more effective in reducing eczema (five studies, 572 participants, RR 2.46, 95% CI 1.16 to 5.23; low-quality evidence) and itch (seven studies, 749 participants, SMD -1.10, 95% CI -1.83 to -0.38) than control. Participants in both treatment arms reported comparable satisfaction (three studies, 296 participants, RR 1.35, 95% CI 0.77 to 2.26; low-quality evidence). Moisturisers led to lower investigator-assessed disease severity (12 studies, 1281 participants, SMD -1.04, 95% CI -1.57 to -0.51; high-quality evidence) and fewer flares (six studies, 607 participants, RR 0.33, 95% CI 0.17 to 0.62; moderate-quality evidence), but there was no difference in adverse events (10 studies, 1275 participants, RR 1.03, 95% CI 0.82 to 1.30; moderate-quality evidence).Topical active treatment combined with moisturiser was more effective than active treatment alone in reducing investigator-assessed disease severity (three studies, 192 participants, SMD -0.87, 95% CI -1.17 to -0.57; moderate-quality evidence) and flares (one study, 105 participants, RR 0.43, 95% CI 0.20 to 0.93), and was preferred by participants (both low-quality evidence). There was no statistically significant difference in number of adverse events (one study, 125 participants, RR 0.39, 95% CI 0.13 to 1.19; very low-quality evidence). Participant-assessed disease severity was not addressed. AUTHORS' CONCLUSIONS Most moisturisers showed some beneficial effects, producing better results when used with active treatment, prolonging time to flare, and reducing the number of flares and amount of topical corticosteroids needed to achieve similar reductions in eczema severity. We did not find reliable evidence that one moisturiser is better than another.

Abstract
Eczema is a common skin inflammatory disorder particularly among children. The treatment of which usually consists of the application of emollients and moisturisers to maintain skin moisture and to reduce the risk of inflammation, infection and exacerbative factors. Recently, DreamSkin® Health Limited has developed a unique polymer treatment for eczema. The polymer has been applied to medical grade silk clothing as a means of delivering the therapeutic benefits to the sufferers' skin. They claim that the polymer reduces the loss of moisture caused by evaporation from damaged skin; acts as a barrier against external irritants and helps to restore the skin's natural temperature management process. The aim of this study was to assess the products effectiveness at providing symptomatic relief for a volunteer with confirmed eczema and atopic dermatitis over a period of 14 days. Both skin capacitance and NIR spectra were collected during the course of the study, using the Corneometer® CM 825 and a spectrophotometer equipped with a customized reflectance probe for measurements in the Near Infrared region. The treated area showed visibly improved skin and overall results from both techniques showed a noticeable increase in skin water content after 14 days, peaking on the 7th day. However, slight differences were observed in the 7 magnitude of increase between the two instruments. Future work will focus on expanding this study to include more cases as well as performing statistical analysis to build upon our previous work in the area of skin hydration determinations using Near Infrared Spectroscopy.

Abstract
Pruritus, or itch, is defined as "a sensation that, if sufficiently strong, will provoke scratching or the desire to scratch." Pruritus is a symptom associated with a wide variety of causes and treatment options. Topical therapy is becoming the new target for the treatment of pruritus. The treatment of pruritus in the dog must be approached in a systematic manner and should include the search and resolution of the primary causes. Identifying and treating the primary cause of pruritus greatly increases the success rate of any therapy for pruritus.

Abstract
Atopic dermatitis is a common, pruritic, inflammatory skin disorder. Chronic, localized, or even generalized pruritus is the diagnostic hallmark of atopic dermatitis, and its management remains a challenge for physicians. The threshold for itch and alloknesis is markedly reduced in these patients, and infections can promote exacerbation and thereby increase the itch. Modern management consists of anti-inflammatory, occasionally antiseptic, as well as antipruritic therapies to address the epidermal barrier as well as immunomodulation or infection. Mild forms of atopic dermatitis may be controlled with topical therapies, but moderate-to-severe forms often require a combination of systemic treatments consisting of antipruritic and immunosuppressive drugs, phototherapy, and topical compounds. In addition, patient education and a therapeutic regimen to help the patient cope with the itch and eczema are important adjuvant strategies for optimized long-term management. This review highlights various topical, systemic, and complementary and alternative therapies, as well as provide a therapeutic ladder for optimized long-term control of itch in atopic dermatitis.

Abstract
The article presents data confirming the efficacy of external application of Locobase Repair cream and Atoderm cream in a combination
with hydrocortisone 17-butyrate 0.1% (Locoid ointment) in children aged from 6 months to 12 years suffering from moderate
atopic dermatitis. The patients were followed up for a year. The treatment efficacy was estimated according to the dynamics of
the SCORAD index and skin instrumental examination indices (corneometry, tewametry and pH-metry). The life quality in children
younger than 5 years was estimated based on the Childrens Dermatology Life Quality Index (CDLQI). The external therapy mentioned
above resulted in the decreased frequency of atopic dermatitis exacerbations, their reduced severity, increased duration of
inter-recurrent periods and reduced need in topical corticosteroids.

Abstract
Atopic dermatitis is a common condition characterized by pruritus, inflammation, and dryness of the skin. Inflammation disrupts the barrier function of the stratum corneum, predisposing the skin to be dry, and increases susceptibility to irritants and secondary bacterial infection. Sensitive skin is common, reported by 40-50% of women and 30% of men in the US, Europe, and Japan. Basic requirements in managing eczema and sensitive skin include effective cleansers that do not compromise skin barrier integrity, alleviation of skin dryness, and restoration of skin barrier function through the use of therapeutic moisturizers. The selection of a skin cleanser is therefore an important part of managing these conditions. Studies have reported clinical improvement with the use of soap-free cleansers in combination with topical treatments. While topical corticosteroids and immunosuppressive agents are mainstays of treatment for atopic dermatitis, therapeutic moisturizers are important adjuncts. Moisturizers improve skin hydration, reduce susceptibility to irritation, restore the integrity of the stratum corneum, and enhance the efficacy of topical corticosteroids.

Abstract
BACKGROUND Atopic dermatitis (AD) requires permanent skin care. OBJECTIVE A cream containing 2% SO (sunflower oleodistillate), with peroxisome proliferator-activated receptor-alpha (PPAR-α) agonist properties, has been compared to a topical steroid (hydrocortisone butyro-propionate 1 mg/g). METHODS An open, randomized study included two groups of 40 children (aged 3 months to 4 years). Group A applied the steroid and group B applied the 2% SO cream, twice a day. SCORAD (SCORing Atopic Dermatitis) was determined at D0, D7 and D21 and quality of life (QoL) at D0 and D21. RESULTS SCORAD was similar at D0 (37.2 versus 36.9), D7 (18.9 versus 19.2) (-49% and -48%) and D21 (11 versus 9.4) (-70% and -75%) (p < 0.01 versus D0). The Infant Dermatitis Quality of Life and Dermatitis Family Impact Questionnaire improved similarly by 65%/67% in group A and 72%/75% in group B at D21 (p < 0.01 versus D0). CONCLUSION A 2% SO cream has demonstrated therapeutic properties, using clinical scores and QoL, comparable to those of a topical steroid.

Abstract
BACKGROUND Although moisturizer usage has been considered a mainstay of treatment for atopic dermatitis (AD) patients, few clinical studies have been investigated. Recently, moisturizers containing non-steroidal anti-inflammatory agents, such as licochalcone A (LA) and vitamin B(12) are of emerging interest. OBJECTIVE To compare the effectiveness of moisturizer containing LA with hydrocortisone (HC) lotion in treatment of childhood AD. Methods The randomized, controlled, investigator-blinded 6-week study was conducted. Patients were administered with twice-daily application of LA lotion on one side of the body and HC lotion on the opposite side. The clinical outcome was assessed by the scoring of atopic dermatitis (SCORAD) index. The relapse rate was comparatively analysed by survival analysis. RESULTS From 30 patients enrolled, 26 patients completed the protocol. The mean age of the children was 5.8 years. The average baseline SCORAD score is about 28 on both sides. The response rates of both agents were equal to 73.33%. There is no statistical significant group difference in reduction of SCORAD score. Although we observed more rapid resolution of oedema and erythema in areas treated with HC lotion, both agents exhibited no significant difference. The relapse rate of HC group was higher than in LA group; however, there was no significant difference. No side-effect was observed from both agents. CONCLUSION The effectiveness of LA lotion is equal to that of HC lotion. It was suggested that moisturizer containing LA could be used both for treatment of acute and maintenance phase in mild-to-moderate childhood AD.

Abstract
Objective: To evaluate the available treatment options for pediatric atopic dermatitis, Data Sources: A literature review was performed in MEDLINE (1950-February 2010) using the key word atopic dermatitis. The references identified were evaluated in comparative treatment. The references included in this review were limited to studies conducted in children less than 18 years of age and written in the English language. Study Selection and Data Extraction: All of the literature retrieved that was published within the last 5 years (2005-2010) was included in this review. Other pertinent articles published prior to 2005 were also included. Data Synthesis: Atopic dermatitis is a chronic inflammatory skin disorder that usually begins during infancy. Potential causes include irritants such as soap and detergents, food allergens, contact allergens, and skin infections. Emollients, moisturizing agents that inhibit water loss and provide a protective coating, are recommended in all patients with atopic dermatitis. Additionally, emollients may reduce the need to use topical corticosteroids. Patients receiving desanide 0.05% plus an emollient achieved significant reductions in severity scores compared to those receiving desonide 0.05% as monotherapy (80% vs 70%; p < 0.01). Topical calcineurin inhibitors are not recommended as first-line therapy in pediatric patients with atopic dermatitis; however, their use in children above 2 years of age who fail to respond to topical corticosteroids may be considered. Conclusions: Emollients are recommended in pediatric patients with a diagnosis of atopic dermatitis regardless of symptoms. Topical corticosteroids reduce the inflammation and pruritus associated with atopic dermatitis and are available in several formulations and strengths. Calcineurin inhibitors may be an alternative in children older than 2 years of age who do not respond to topical corticosteroids,

Abstract
Atopic dermatitis is a common, complex disease that frequently follows a chronic, relapsing course. The disease can impact the quality of life (QOL) of patients and families to a significant degree. Patients and caregivers may focus on unproven triggers at the expense of proper skin care. A multidisciplinary approach is needed to comprehensively evaluate triggers and response to treatment, address confounding factors including sleep disruption, and educate patients and caregivers.

Abstract
The aim of the study was to investigate whether adding emollients to the standard topical corticosteroid therapy influences the outcome of children with atopic dermatitis. Fifty-two children aged between 2 and 12 yr were divided randomly in two subgroups consisting of 26 children each. Both groups applied 0.1% methylprednisolone aceponate cream on lesional atopic skin once daily for 2 wk and were observed for another 4 wk after treatment discontinuation. Group B used additionally emollients for the whole study period. Patients were evaluated at days 0 (baseline), 7, 14 (end of therapy), 28 and 42 (follow-up). Both groups demonstrated significant improvement of disease severity according to EASI (Eczema Area and Severity Index) scale (group A: 6.8 +/- 3.59 before and 0.87 +/- 1.25 after therapy, p < 0.001; group B: 9.6 +/- 8.39 before and 1.11 +/- 2.37 after therapy, p < 0.001). Xerosis improved significantly better in group B compared to group A, both clinically (group A: 1.38 +/- 0.57 scores before and 1.5 +/- 0.58 scores after therapy, p = 0.11; group B: 1.62 +/- 0.64 scores before and 0.12 +/- 0.33 scores after therapy, p < 0.001), and by corneometry assessment (group A: 41.7 +/- 9.1 units before and 51.3 +/- 11.3 units after therapy, p < 0.001; group B: 38.9 +/- 12.9 units before and 58.2 +/- 13.5 units after therapy, p < 0.001). A trend towards faster resolving of pruritus in group B (group A: 5.44 +/- 2.6 scores before and 3.22 +/- 2.31 scores after therapy, p = 0.001; group B: 5.87 +/- 2.79 scores before and 2.24 +/- 1.59 scores after therapy, p < 0.001) was also observed. In group B, the improvement was maintained for couple of weeks after treatment discontinuation, while in group A recurrence of the disease was noted (EASI at day 42 in group A vs. group B: 5.29 +/- 5.6 vs. 1.25 +/- 1.4, p = 0.01). Similar results were also observed for xerosis (p < 0.001) and pruritus (p = 0.002). Concomitant usage of emollients significantly improves xerosis and pruritus during corticosteroid treatment of atopic dermatitis and enables to maintain clinical improvement after therapy discontinuation.

Abstract
Emollients are commonly used for their effectiveness on atopic skin, supported by a few clinical studies suggesting their potential role as corticosteroid sparing agents. We investigated the effect of a new natural emollient on corticosteroid sparing and quality of life of young atopic children and their family. Eighty-six patients (4-48 mos) with moderate atopic dermatitis were randomized by 20 pediatricians to five groups for 21 days: corticosteroids (from twice daily to one application every other day) combined or not with the studied cream (twice daily), and evaluated by SCORAD and specific quality of life questionnaires. At the end of the study, all five groups were statistically improved in terms of SCORAD and quality of life index. Thus, application of a topical corticosteroid every other day in addition to the studied cream was as effective as a once or twice daily application of the steroid alone. The studied cream had a significant impact on lichenification, excoriation and quality of life. A twice daily application of a new natural emollient provided a major corticosteroid sparing, improved lichenification and excoriation and improved the quality of life in children and their parents.

Abstract
BACKGROUND The safety of topical therapies for atopic dermatitis (AD), a common and morbid disease, has recently been the focus of increased scrutiny, adding confusion as how best to manage these patients. OBJECTIVES The objective of these systematic reviews was to determine the safety of topical therapies for AD. METHODS Databases searched included: OVID Medline, Medline In-Process and Other Non-Indexed Citations, Embase, and the Cochrane Central Register of Controlled Trials. In addition to the articles identified by this search, investigators were also referred to a list of links (most recently updated 25 September 2005) to recent Food and Drug Administration (FDA) studies, reports and meetings regarding the topical calcineurin inhibitors for further potential references. Only fully published papers available in English and data obtained from FDA sites were included. Furthermore, the criteria for inclusion and exclusion for each systematic review were further evaluated at a meeting of all of the content and evidence-based medicine experts participating in this process and alteration of the inclusion criteria was done at that time when it was felt necessary to avoid inclusion of lower-quality data in the review. Qualitative review of the abstracted data was performed and reviewed at a meeting of all of the content and evidence-based medicine experts. RESULTS While systemic exposure to these topical agents does occur, physiological changes appear to be uncommon and systemic complications rare and have only been found with use of topical corticosteroids. CONCLUSIONS Based on the data that are available the overall safety of AD therapies appears to be good with the only documented systemic side-effects of therapy those occasionally seen with use of topical corticosteroids.

Abstract
BACKGROUND No study has clearly demonstrated the steroid-sparing effect of emollients in the treatment of atopic dermatitis (AD). AIM Evaluating the effect of an emollient containing oat extracts on the amount of topical corticosteroids used in infants with moderate to severe AD. STUDY DESIGN During 6 weeks, 173 infants under 12 months old treated for inflammatory lesions by moderate- and/or high-potency topical corticosteroids randomly received the emollient or not (control group). METHODS Evaluation of corticosteroid consumption by weighing the tubes, disease severity by the Scoring Atopic Dermatitis Index (SCORAD), and infants' and parents' quality of life by Infant's Dermatitis Quality of Life Index and Dermatitis Family Impact scores at D0, D21 and D42. RESULTS Compared to the control group, the amount of moderate- and high-potency corticosteroids used in 6 weeks decreased by 7.5% (not significant) and 42% (p < 0.05), respectively, in the emollient group. The SCORAD index, and infants' and parents' quality of life significantly improved (p < 0.0001) in both groups. CONCLUSION The emollient treatment significantly reduced the high-potency topical corticosteroid consumption in infants with AD.

Abstract
A shift in focus from disease therapy toward disease prevention is occurring in many medical specialties, including dermatology. There are no generally accepted strategies for the prevention of atopic dermatitis. Most research has focused on allergen avoidance and has not produced consistently effective interventions. Immune cell modulation and skin barrier protection are examples of new approaches that hold promise for preventing, or modifying the course of, this common disease.

Abstract
The prevalence of atopic dermatitis is increasing, and more than 50% of children with atopic dermatitis go on to develop asthma and allergies. A better understanding of the underlying immune abnormalities of this complex chronic relapsing skin disease is needed. Although the optimal treatment approach remains to be defined, several recent studies suggest a rationale for using topical calcineurin inhibitors as early intervention and adding topical corticosteroids as rescue therapy if needed.

Abstract
Topical therapy of atopic dermatitis should incorporate an understanding of the underlying immune abnormalities of this complex chronic skin disease. Avoidance of irritants and proven allergens, skin hydration, and use of emollients and anti-inflammatory therapy help maintain a normal skin barrier. Topical calcineurin inhibitors have been added to the topical treatment armamentarium. Although the optimal treatment approach remains to be defined, several studies suggest the use of topical calcineurin inhibitors as early intervention therapy and topical corticosteroids as rescue therapy.

Abstract
Well-designed clinical trials are a fundamental aspect of evidence-based medicine. Such trials are dependent on the use of valid, reliable, and relevant outcome measures. Wide variation in outcome methodology can have important detrimental effects on the correct interpretation and comparison of results. The objective of this study was to describe the variation in outcome methodology in randomized controlled trials of therapeutic interventions for atopic dermatitis published between January 1994 and December 2001. Of the 93 eligible randomized controlled trials identified using a systematic electronic database search strategy, 85 (91%) incorporated an objective measurement of clinical signs. Only 23 (27%) of these trials used a published severity scale, however. The remainder used either modified versions of published scales (14%) or unnamed scales with no data on validity or reliability (59%), although unpublished scales were used significantly less frequently over the last 2 y compared to previously (21%vs 74%, p<0.01). There was lack of consensus on which clinical features best reflect disease severity, with 31 different descriptions of clinical signs being used across all scoring systems. Fifty-six different "objective" clinical scales were identified. Patient symptoms were recorded in 80 trials (86%) and disease extent in 62 trials (67%). Quality of life was measured in only three trials (3%). This wide variation in outcome methodology is hindering evidence-based practice, and the widespread use of unvalidated outcome measures is a potential source of bias and inaccuracy. More emphasis should be placed on measuring things that are important to patients such as symptoms and quality of life.
