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...

BACKGROUND: The stratum corneum is an almost impermeable barrier. Recently, microneedles have been used to increase drug delivery passing the stratum corneum by incorporating the drug within the microneedle or by coating the surface of the microneedle with the drug. OBJECTIVE: This study was performed to investigate whether applying a biodegradable microneedle patch after topical steroid application increases penetration of the steroid in vitro, as well as treatment efficacy in patients with prurigo nodularis...

<p>Atopic dermatitis and prurigo nodularis result from complex interactions between the skin, the immune system, and the external environment. The pruritus associated with these conditions greatly impacts patients' quality of life and lacks uniformly effective treatment. A 57-year-old patient presented with severe atopic dermatitis and subsequent prurigo nodularis refractory to numerous standard therapies. The supplement isoquercetin was initiated and he noted significant, sustained reduction in his pruritus after only four weeks...

Prurigo nodularis (PN) is a subtype of chronic prurigo presenting single to multiple symmetrically distributed, hyperkeratotic and intensively itching papules and nodules. PN evolves along with chronic pruritus in the context of diverse dermatological, systemic, neurological or psychiatric conditions. Permanent scratching is possibly a major trigger of PN, although its exact pathophysiology remains unclear. Current state-of-the-art therapy for PN consists of topical steroids, capsaicin, calcineurin inhibitors, ultraviolet (UV) therapy, systemic administration of gabapentinoids, μ-opioid receptor antagonists, antidepressants or immunosuppressants...

Herein, we report a unique case of generalized eruptive keratoacanthoma (GEKA) in a 47-year-old Chinese man presenting with extensive pruritic papules and nodules accompanied by oral lesions. He also had a 2-year history of vitiligo and long-term experience of working outdoors. Biopsies were consistent with keratoacanthoma . Interestingly, prurigo nodularis (PN) was found in histopathology at 1-year follow up. To our knowledge, this is the first report describing a case of GEKA with oral lesions complicated with vitiligo and developed with PN...

Helicobacter pylori is a gram-negative, flagellate, microaerophilic bacterium identified for the first time about 30 years ago, as a pathogenic factor of gastritis and peptic ulcer. Soon after, it was linked to several gastrointestinal and extra-gastrointestinal diseases (hematological, cardiovascular, neurological, pulmonary and ocular diseases, obesity, diabetes mellitus, growth retardation and extragastric MALT lymphoma). Association and possible cause-effect correlation with H. pylori infection were suggested in diseases of dermatological interest such as chronic urticaria, rosacea, Henoch-Schoenleins purpura, idiopathic thrombocytopenic purpura, cutaneous and oral lichen planus, atopic dermatitis, recurrent aphthous stomatitis, systemic sclerosis, psoriasis, Sjögrens syndrome, Behçet's disease, pruritus, alopecia areata, primary cutaneous marginal zone B-cell lymphomas, vitiligo, chronic prurigo, multiformis, prurigo nodularis, leukocytoclastic vasculitis, prurigo pigmentosa, eczema nummulare, primary cutaneous MALT-type lymphoma, sublamina densa-type linear IgA bullous dermatosis, Sweet's syndrome, cutaneous T-cell pseudolymphoma and pemphigus vulgaris...

The skin and psyche are intimately related with various skin diseases caused by or resulting in psychiatric disturbances. Pruritus is a commonly reported symptom in psychiatric patients, and likewise psychiatric co-morbidities, including anxiety and depression, are frequently seen in chronic pruritus patients. Primary psychodermatologic conditions, such as somatic symptom disorder, dermatitis artefacta, obsessive-compulsive and related disorders (excoriation disorder and prurigo nodularis), delusional infestation, and substance use disorder, can all induce significant pruritus in patients, severely affecting their quality of life...

Dissociation and conversion (defined as the somatic component of dissociation) can play an important mediating role in the exacerbation of the stress-reactive dermatoses (eg, psoriasis, idiopathic urticaria, atopic dermatitis), dermatoses that are exacerbated by excessive scratching (eg, lichen simplex chronicus, prurigo nodularis) and koebnerization, and the self-induced dermatoses (dermatitis artefacta, acne excoriée, skin picking disorder, trichotillomania, onychotillomania/onychophagia). Dissociative symptoms often coexist with obsessive-compulsive symptoms in the more severe cases of the self-induced dermatoses...

Immunoglobulin G4-related disease (IgG4-RD) is a systemic inflammatory condition characterized by tissue infiltration with IgG4+ plasma cells and an elevated serum IgG4 level. It usually occurs in middle-aged or older patients, with male predominance, and can involve multiple organs synchronously or metachronously. Patients with IgG4-RD generally respond to steroid therapy. IgG4-related skin lesions are typically erythematous and itchy plaques, subcutaneous nodules, or papules like prurigo nodularis located on the head and neck areas...

An abnormal change in skin colour is designated as discolouration of the skin. A 73-year-old male patient with circumscribed discolouration of the upper lid margin near the lacrimal pathway is presented. Slit lamp biomicroscopy showed no other signs of pathomorphological change. An excisional biopsy was performed. The whole abnormal area was removed. The oculoplastic procedure was the surest way to establish a definite diagnosis of Prurigo nodularis.

Mark R Wick
Psoriasis vulgaris (PV)-the prototypical "psoriasiform" dermatitis-may assume a spectrum of histologic appearances, depending on whether it has been treated or not. Because of that relative lack of morphological uniformity, other skin disorders that feature epidermal acanthosis, with or without associated inflammation, may be confused diagnostically with PV. This brief review considers the clinicopathologic attributes of PV and its imitators, including chronic spongiotic dermatitides, lichen simplex chronicus, prurigo nodularis, pityriasis rubra pilaris, psoriasiform secondary syphilis, and Reiter syndrome...

Levocetirizine is a second-generation nonsedative antihistaminic agent that has been demonstrated to be safe and effective for treating allergic disease. There was only one case report of levocetirizine-induced liver toxicity, but a liver biopsy was not performed. In this article, we present the first case of levocetirizine-induced liver injury with histologic findings. A 48-year-old man was hospitalized with jaundice and generalized pruritus that had developed after 2 months of therapy with levocetirizine for prurigo nodularis...

REVIEW
A E Kremer, K Wolf, S Ständer
Intrahepatic cholestasis of pregnancy (ICP) is a liver-specific disorder occurring in approximately 0.5-2.0% of all pregnancies with a considerable variation in certain ethnic groups. ICP usually runs a benign course for the mother and is characterized by maternal pruritus mainly in the third trimester, elevated transaminases and fasting total serum bile salts and increased fetal adverse events. The etiology of ICP is only partially understood but seems to be multifactorial. Cholestasis-inducing effects of certain female sex hormones and their metabolites play an important role in genetically susceptible women...

REVIEW
Nazanin Foroutan, Naemeh Nikvarz
Pruritus can be one of the distressing symptoms of many dermatologic, systemic, neurologic or psychiatric disorders. In each case, the origin of itch is in the skin and/or the nervous system. Involvement of the nervous system causes neurogenic, psychogenic or neuropathic itch. Itch sensation is transferred to the central nervous system via unmyelinated C-type nerve fibers, and many mediators and receptors engage in the its induction and transmission. Also it has been demonstrated that there are similarities and interactions between neurotransmitters and pathways of pain and itch sensation...

Prurigo nodularis (PN) is an intensely pruriginous dermatological disorder whose treatment is challenging for dermatologists. It is characterized by eruptions of papules and hyperkeratotic nodules, some of which are eroded, on the extensor surfaces of the limbs. The most commonly used treatments for this condition are oral antihistamines and topical or systemic steroids. Thalidomide is an effective treatment option in cases of recalcitrant PN; however, its most frequent adverse effect is neurotoxicity, which often results in its discontinuation...
