Atopic dermatitis (AD) is a highly pruritic, chronic inflammatory skin disease. The diagnosis is made using evaluated clinical criteria. Disease activity and burden are best measured with a composite score, assessing both objective and subjective symptoms, such as SCORing Atopic Dermatitis (SCORAD). AD management must take into account clinical and...

Attenuated total reflectance Fourier transform infrared spectroscopy (FTIR) is a useful technique for the molecular analysis of surfaces, including the skin, with promising translational clinical potential. Skin‐surface levels of natural moisturizing factor (NMF) are a biomarker of filaggrin (FLG) status (both inherited and acquired) and skin dryne...

Background and Aim: With inflammatory skin conditions such as atopic dermatitis (AD), epidermal thickness is mediated by both pathological hyperplasia and atrophy such as that resulting from corticosteroid treatment. Such changes are likely to influence the depth and shape of the underlying microcirculation. Optical coherence tomography (OCT) provi...

Background: Preventing relapses of atopic dermatitis (AD) through the regular use of topical products to repair the skin barrier defect is an emerging concept. It is still unclear if some commonly used emollients exert a positive effect on the skin barrier. Objectives: To determine the skin barrier effects of emollients commonly prescribed in th...

Xerosis affects up to 75% of older people and develops as a result of a skin barrier defect. Emollients are widely used to treat xerosis; however, there is limited understanding of the differences between them and their effects on the skin barrier in older people. This study aimed to compare the effect of a commercially available emollient containi...

Background: From birth, the functional properties of the neonatal epidermal barrier mature whereby the stratum corneum (SC) hydrates and the skin surface acidifies. The identification of a thinner infant SC compared to adults suggests underdeveloped mechanisms underlying differentiation and desquamation. Objectives: To assess the functional prop...

Background: European roundtable meeting recommendations on bathing and cleansing of infants were published in 2009; a second meeting was held to update and expand these recommendations in light of new evidence and the continued need to address uncertainty surrounding this aspect of routine care.

Background The use of baby wipes is common for cleansing of babies' skin. However, with the use of wipes come differing, and often conflicting perceptions, due to an absence of published research tackling the safety and efficacy of disposable baby wipes. Although studies have evaluated the use of baby wipes, these have tended to be on older babies...

Olive oil is commonly recommended by health professionals to new parents for use in the prevention and treatment of the term baby's dry skin, and for baby massage. There is no evidence to support this practice. The use of olive oil may be harmful to skin, affecting skin barrier function. This effect may be a contributory factor in the prevalence of...

Atopic dermatitis (AD) is a chronic, inflammatory disease of the skin characterised by xerosis, pruritus and erythematous lesions with increased trans-epidermal water loss (TEWL). AD is associated with a skin barrier defect, which permits the entry of irritants and allergens. Variants within three groups of genes, encoding structural proteins, degr...

Background: The vulnerability of newborn babies' skin creates the potential for a number of skin problems. Despite this, there remains a dearth of good quality evidence to inform practice. Published studies comparing water with a skin-cleansing product have not provided adequate data to inform an adequately powered trial. Nor have they distinguish...

The emollient aqueous cream BP is frequently used for the treatment of atopic dermatitis (AD), yet it is associated with a high rate of adverse cutaneous reactions. It contains the harsh anionic surfactant sodium lauryl sulphate, a known negative environmental factor associated with the exacerbation of AD. To investigate the effect of aqueous cream...

Allergic contact dermatitis in children is less recognized than in adults. However, recently, allergic contact dermatitis has started to attract more interest as a cause of or contributor to eczema in children, and patch testing has been gaining in recognition as a useful diagnostic tool in this group. The aim of this analysis was to investigate th...

Psoriasis is an inflammatory skin disorder that exhibits multifactorial mode of inheritance. In addition to the well-known susceptibility locus PSORS1 many other loci have been shown to be implicated in the genetic predisposition for disease. However, interactions between loci have not been thoroughly explored. Thus, we measured the effect of poten...

Background: Over the last decade, health professionals have debated the relative merits and potential harms of various neonatal bathing practices. Two schools of thought exist - those that support the use of water alone, and those who believe that bathing products offer some benefit. However, there is a dearth of empirical evidence on which to info...

Development of the skin barrier continues up to 12 months after birth; therefore, care must be taken when cleansing and bathing infants' skin. Available guidelines for skin care in newborns are, however, limited. In 2007, the 1st European Round Table meeting on 'Best Practice for Infant Cleansing' was held, at which a panel of expert dermatologists...

Atopic dermatitis (AD) is a multifactorial, heterogenous disease that arises as a result of the interaction between both environmental and genetic factors. Changes in at least three groups of genes encoding structural proteins, epidermal proteases, and protease inhibitors predispose to a defective epidermal barrier and increase the risk of developi...

Breakdown of the skin barrier is the first event in the development of atopic eczema (atopic dermatitis). Research over the past five years has indicated that this arises as a result of the interaction of environmental agents such as soap and other detergents with the products of changes in several genes. These genetic changes predispose to the bre...

Chronic plaque psoriasis is the most common type of psoriasis and is characterised by redness, thickness and scaling. First line management of chronic plaque psoriasis is with topical treatments, including vitamin D analogues, topical corticosteroids, tar-based preparations, dithranol, salicylic acid and topical retinoids.

Vitiligo is an autoimmune disorder that occurs with greatly increased frequency in the rare recessive autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy syndrome (APECED) caused by mutations of the autoimmune regulator (AIRE) gene on chromosome 21q22.3. We have previously detected an association between alopecia areata and single nucleo...

Desquamation occurs after proteolysis of corneodesmosomal proteins, including corneodesmosin (CDSN), by proteases of the kallikrein family, particularly KLK7. Impaired desquamation is one of the features of psoriasis, and psoriasis-associated single nucleotide polymorphisms of the CDSN gene may potentially modify the proteolysis of the encoded prot...

Alopecia areata is an immune-mediated disorder, occurring with the highest observed frequency in the rare recessive autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) syndrome caused by mutations of the autoimmune regulator (AIRE) gene on chromosome 21q22.3. We have previously detected association between alopecia areata and a...

Atopic dermatitis (AD) is a multifactorial, heterogeneous, disease that arises as a consequence of the interaction between genetic and environmental factors. Genetic variants found within several groups of genes have been associated with the development of a defective skin barrier including protease, protease inhibitor and structural genes. Loss-of...

Family-based analysis has revealed several loci for psoriasis and the locus, PSORS5, on chromosome 3q21 has been found in two independent studies. In this region, cystatin A (CSTA) encodes a skin barrier cystein protease inhibitor found in human sweat and it is over-expressed in psoriatic skin. Three CSTA markers at positions -190 (g.-190T>C), +162...

In this report, we review the data on the safety and tolerability of pimecrolimus cream 1&percnt; (Elidel®) from clinical trials and post-marketing surveillance in patients with atopic dermatitis. These data demonstrate that topically applied pimecrolimus is minimally absorbed through the skin and has afavourable safety margin. The most common trea...

Cystatin A (CSTA) is a strong candidate for atopic dermatitis (AD) because it maps to AD susceptibility locus on chromosome 3q21 and it does inhibit Der p 1 and Der f 1, major house dust mite cysteine proteases and environmental triggers for AD and asthma. To examine any association between polymorphisms in CSTA and AD and study the effect on the C...

Alopecia areata is an acquired hair loss disorder resulting from an immunologically- mediated attack on hair follicles and autoimmunity may play a part in its pathogenesis. The non-synonymous C1858T substitution in the PTPN22 gene, which encodes lymphoid protein tyrosine phosphatase, has been shown to be associated with susceptibility to autoimmune...

Atopic dermatitis (AD) is a multifactorial, chronic inflammatory skin disorder in which genetic mutations and cutaneous hyperreactivity to environmental stimuli play a causative role. Genetic mutations alone might not be enough to cause clinical manifestations of AD, and this review will propose a new perspective on the importance of epidermal barr...

Young people who are concerned that consultations may not remain confidential are reluctant to consult their doctors, especially about sensitive issues. This study sought to identify issues and concerns of adolescents, and their parents, in relation to confidentiality and teenagers' personal health information. Recruitment was conducted in paediatr...

The pro-inflammatory cytokine interleukin-1 (IL-1) is constitutively expressed by keratinocytes in vivo and has been shown to be expressed in psoriatic lesional skin. To determine what role the IL-1 system might contribute to the inflammatory process in psoriasis, semi-quantitative RT-PCR and cRNA microarray studies were performed on biopsies excis...

We questioned the significance of haplotype structure in gene regulation by testing whether individual single nucleotide polymorphisms (SNPs) within a gene promoter region [interleukin-1-beta (IL1B)] might affect promoter function and, if so, whether function was dependent on haplotype context. We sequenced genomic DNA from 25 individuals of divers...

Unlabelled: Topical corticosteroids were introduced into medicine about 50 years ago. They represent a significant milestone in dermatologic therapy. Despite encouragement to report observed adverse drug reactions, the clinical practice of reporting is poor and incomplete. Likewise, adverse effects and safety of topical corticosteroids are neglect...

Pimecrolimus is a calcineurin inhibitor developed for the topical treatment of atopic dermatitis. During the clinical development of 1% pimecrolimus cream, 1133 patients 3 to 23 months of age with mild to severe atopic dermatitis were treated for up to 2 years. The objective of this review is to discuss the safety and tolerability of 1% pimecrolimu...

Genes that control the thickness of our skin and its vulnerability to chemicals in the environment play a role in the development of contact dermatitis and atopic eczema. Sensitive skin manifests itself as a burning, stinging or itching sensation following the application of topical products such as soap, bubble baths and cosmetics. The skin may be...

Outcomes of health care interventions can be measured in many different ways, but there has been growing interest in the role that quality-adjusted life-years (QALYs) can play in informing priorities in health care. While existing generic preference-based measures can be used to obtain QALYs, these measures may often be inappropriate for some condi...

Psoriasis is a chronic inflammatory skin disease that affects 0.1%-5% depending on the population. PSORS1 is the major susceptibility locus, accounting for approximately 33%-50% of the genetic component of psoriasis among Caucasians. PSORS1 is located within the major histocompatibility complex (MHC) locus on 6p21.3. Its position has been refined t...
