Mindfulness-based cognitive hypnotherapy integrates mindfulness, cognitive-behavioral therapy, and hypnotherapy to improve physical, emotional, mental, and/or spiritual aspects of skin disorders. Meditation, including mindfulness meditation, and hypnosis both utilize trance phenomena to help produce focalization and specific improvements in skin disorders through psycho-neuro-endocrine-immunologic mechanisms. Hypnosis, cognitive hypnotherapy, focused meditation, and mindfulness meditation are discussed with respect to improving various skin disorders including acne, acne excoriée, alopecia areata, atopic dermatitis, congenital ichthyosiform erythroderma, dyshidrotic dermatitis, erythema nodosum, erythromelalgia, furuncles, glossodynia, herpes simplex, hyperhidrosis, ichthyosis vulgaris, lichen planus, neurodermatitis, nummular dermatitis, postherpetic neuralgia, prurigo nodularis, pruritus, psoriasis, rosacea, trichotillomania, urticaria, verruca vulgaris, and vitiligo...

Eyelash trichomegaly (ET) is increased length (≥ 12 mm), curling, pigmentation, or thickness of eyelashes. Among acquired causes, allergic diseases and atopic dermatitis (AD) have been found to be associated with eyelash trichomegaly especially in children; however, to date, this claim has not been studied in detail. To compare the eyelash lengths of AD and ichthyosis vulgaris (IV) patients with those of age- and sex-matched patients with unrelated skin disorders, we measured (with a digital Vernier caliper) and compared the eyelash lengths of AD (n = 58) and IV (n = 31) patients to those of age- and sex-matched patients with unrelated skin disorders (n = 178)...

Recessive X-linked ichthyosis (XLI), the second most common ichthyosis, is caused by mutations in the STS gene encoding the steroid sulfatase enzyme. A complete deletion of the STS gene is found in 85-90% of cases. Rarely, larger deletions involving contiguous genes are detected in syndromic patients. We report the clinical and molecular genetic findings in a series of 35 consecutive Italian male patients. All patients underwent molecular testing by MLPA or aCGH, followed, in case of negative results, by next generation sequencing analysis...

Ichthyosis is a broad and loosely defined group of hereditary and acquired disorders characterized by filaggrin dysfunction and impaired epidermal homeostasis that results in dry, scaly and thickened skin. Individuals with truncation mutations in the profilaggrin gene coding for filaggrin are strongly predisposed to severe forms of ichthyosis. The phenotypical expression of ichthyosis caused by the same genotypical mutation can vary considerably in severity and in regards to how much constricting scar tissue develops...

Previous transcriptome analyses underscored the importance of immunological and skin barrier abnormalities in atopic dermatitis (AD). We sought to identify pathogenic pathways involved in AD by comparing the transcriptomes of AD patients stratified for filaggrin (FLG)-null mutations to those of both healthy donors and patients with ichthyosis vulgaris. We applied RNA sequencing to analyze the whole transcriptome of nonlesional skin. We found that 607 genes (476 up-regulated and 131 down-regulated by >2-fold) and 193 genes (172 up-regulated and 21 down-regulated by >2-fold) were differentially expressed when all AD or ichthyosis vulgaris patients were compared with healthy donors, respectively...

We present concurrent X-linked chondrodysplasia punctata and ichthyosis vulgaris in adolescent fraternal twin girls, notable for initial presentation with dry skin in adolescence, characterized by dark-brown scale typical of ichthyosis vulgaris and blaschkolinear, atrophic, scaly plaques. This constellation of findings prompted further genetic investigation. Using a multigene approach to examine 39 genes associated with congenital ichthyosis, next-generation sequencing revealed a novel heterozygous missense mutation at a mutational hotspot in the EBP gene c...

X-linked ichthyosis (XLI) is a relatively common, recessive condition caused by mutations in the steroid sulfatase (STS) gene. Common loss-of-function mutations in the filaggrin gene (FLG) cause ichthyosis vulgaris and predispose individuals to atopic eczema. We report a case of a 6-year-old boy who presented with unusually severe XLI, an increased serum immunoglobulin E level (2120IU/ml) and moyamoya angiopathy. Whole-exome sequencing identified a gross deletion encompassing the STS in Xp22.31 and the p.K4022X FLG mutation...

Atopic dermatitis is a common skin disorder with a complex, evolving pathogenesis. Research on the pathogenesis has shifted from focusing primarily on generalized immune system abnormalities in T helper 1/T helper 2 (Th 1/Th 2) activity to more targeted immune and skin barrier abnormalities contributing to the overall phenotype. Specific signaling pathways recently implicated in atopic dermatitis include production of interleukin (IL) 4 and IL-13, which promote immunoglobulin E production, Th 17 and Th 22 cells, and production of cytokines...

BACKGROUND: Symmetrical acrokeratoderma (SAK) is characterized by brown to black hyperkeratotic patches on acral regions. Although epidermal hyperkeratosis and acanthosis are consistent pathological changes, the nature of epidermal hyperplasia is unknown. AIM: To evaluate epidermal proliferation and differentiation and melanocytic density in skin lesions of SAK. METHODS: Expression of keratin 10 (K10), K14, K16, involucrin, filaggrin, Ki-67, and Melan-A was detected by immunohistochemistry in eight patients with SAK, seven patients with ichthyosis vulgaris (IV) and six healthy controls (HCs)...

AP1 transcription factors are important controllers of gene expression in the epidermis, and altered AP1 factor function can perturb keratinocyte proliferation and differentiation. However, our understanding of how AP1 signaling changes may underlie or exacerbate skin disease is limited. We have shown that inhibiting AP1 factor function in suprabasal adult epidermis leads to reduced filaggrin levels and to a phenotype that resembles the genetic disorder ichthyosis vulgaris. We now show that inhibiting AP1 factor function during development in embryonic epidermis produces marked phenotypic changes including reduced filaggrin mRNA and protein levels, compromised barrier function, marked ultrastructural change, and enhanced dehydration susceptibility that resembles the phenotype observed in the flaky tail mouse, a model for ichthyosis vulgaris...

The aim of the study was to evaluate the effects of allelic polymorphism of the FLG and MTHFR genes and their associations in gynecological patients with ichthyosis vulgaris. Gynecological disorders are observed in presence of some forms of ichtyosis. From the prospective of improving nation's healthcare, the greatest attention is drawn to reproductive disorders. Based on this, the research was also tasked with studying of the genetic nature of gynecological diseases, as well as the influence of geographical latitude on the frequencies of mutagenic alleles of the FLG gene and heterogeneous carriers of these mutations...

Mutations of filaggrin gene (FLG) have been identified as the cause of ichthyosis vulgaris, while recently FLG mutations were found to be associated with gastric cancer. This study aimed to investigate the association of filaggrin polymorphism with Epstein-Barr virus-associated tumors in China. A total of 200 patients with three types of tumors and 117 normal control samples were genotyped at three common FLG mutation loci (rs3126085, K4671X, R501X) by using Sequenom MassARRAY technique. The χ 2 test was used to evaluate the relationship between the mutation and the three kinds of tumors...

Ichthyoses are a heterogeneous group of inherited cornification disorders characterized by generalized dry skin, scaling and/or hyperkeratosis. Ichthyosis vulgaris is the most common form of ichthyosis in humans and caused by genetic variants in the FLG gene encoding filaggrin. Filaggrin is a key player in the formation of the stratum corneum, the uppermost layer of the epidermis and therefore crucial for barrier function. During terminal differentiation of keratinocytes, the precursor profilaggrin is cleaved by several proteases into filaggrin monomers and eventually processed into free amino acids contributing to the hydration of the cornified layer...

BACKGROUND: Common loss-of-function mutations in filaggrin gene (FLG) represent a strong genetic risk factor for atopic dermatitis (AD). Homozygous mutation carriers typically display ichthyosis vulgaris (IV) and many have concomitant AD. Previously, homozygous, but not heterozygous, filaggrin gene mutations have been associated with squamous cell carcinomas. OBJECTIVE: The first objective was to examine the association between FLG mutations and actinic keratosis (AK)...

Ichthyosiform dermatosis is a term referred to a group of disorders that have as their basis a disorder of keratinization (1). These conditions which are present at birth result in a generalized dry, scaly skin without any inflammation. There are several types of ichthyosis based on their clinical presentation and mode of inheritance. The most common types are: ichthyosis vulgaris, X-linked recessive ichthyosis, epidermolytic hyperkeratosis (bullous), lamellar ichthyosis and non-bullous ichthyosiform erythroderma...
