Symmetrical Facial Giant Plaque-Type Juvenile Xanthogranuloma: Case Report and Review of the Literature.

Juvenile xanthogranuloma (JXG) is the most common type of non-Langerhans cell histiocytosis. JXG is a rare benign tumor, which may be present at birth or develop later. The classical form of JXG is characterized by a red-yellowish benign papule or nodule with predilection sites on the head, neck, and trunk, although lesions can appear on extremities or extracutaneous sites.

Gene expression is stable in a complete CIB1 knockout keratinocyte model.

Epidermodysplasia verruciformis (EV) is a genodermatosis characterized by the inability of keratinocytes to control cutaneous β-HPV infection and a high risk for non-melanoma skin cancer (NMSC). Bi-allelic loss of function variants in TMC6, TMC8, and CIB1 predispose to EV. The correlation between these proteins and β-HPV infection is unclear.

When life is an itch: What harms, helps, and heals from the patients' perspective? Differences and similarities among skin diseases.

Itch is the commonest skin-related symptom, associated with a high psychosocial and economic burden. While the main focus of itch research lies on a few chronic skin diseases, only little is known about the perception of itch, itch-aggravating/-relieving factors and treatment preferences in patients with acute and chronic itch of various etiology. In this cross-sectional study, we assessed these aspects in 126 patients (mean age 61.

Pain reduction by dehydrated human amnion/chorion membrane allograft in nondiabetic leg ulcers might be an early indicator of good response: A case series.

Dehydrated human amnion/chorion membrane allograft (dHACM) derived from placenta is increasingly used for skin and soft tissue repair in several medical specialties. Promising effects of dHACM were also reported in chronic venous and diabetic leg ulcers. However, dHACM is cost-intensive and its effect on chronic leg ulcers of other etiologies and pain reduction is unknown.

Pruritic and antipruritic colors: An exploratory pilot study.

Itch is the commonest skin-related symptom and can be influenced by visual cues as exemplified by the phenomenon of "contagious itch." Colors are visual cues able to modify somatosensory inputs. We explored the relationship of colors and itch and the impact of color viewing on itch intensity.

Sexually transmitted coinfections in patients with anogenital warts - a retrospective analysis of 196 patients.

Background And Objectives: Anogenital warts (AGWs) are most commonly caused by low-risk human papillomavirus (HPV) types, and although they are the most frequent viral sexually transmitted infections (STIs), little is known about STI coinfections in affected patients. We therefore sought to assess STI coinfection rates in patients with AGW, specify STI coinfections and calculate the number needed to screen (NNS) for each STI.

Methods: A retrospective cross-sectional study analyzing data sets from AGW patients treated in our clinic between 2008-2016.

Arginine- but not alanine-rich carboxy-termini trigger nuclear translocation of mutant keratin 10 in ichthyosis with confetti.

Ichthyosis with confetti (IWC) is a genodermatosis associated with dominant-negative variants in keratin 10 (KRT10) or keratin 1 (KRT1). These frameshift variants result in extended aberrant proteins, localized to the nucleus rather than the cytoplasm. This mislocalization is thought to occur as a result of the altered carboxy (C)-terminus, from poly-glycine to either a poly-arginine or -alanine tail.

[The Interdisciplinary Stomatology Service at the Department of Oral Surgery and Dental Imaging, University Center for Dental Medicine and the University Hospital Basel, Switzerland - Results from 2003 - 2013].

The Interdisciplinary Stomatology Service at the Department of Oral Surgery and Dental Imaging, University Center for Dental Medicine and the University Hospital Basel, Switzerland - Results from 2003 - 2013 Stomatological problems are common, but rarely diagnosed in private dental practice. Even for oral surgeon's diagnosis and therapy of these disorders could be challenging. Stomatological problems can indicate general health problems.

Assessment of the impact of sex in intensity, skin flares and central processing of histaminergic itch-A pilot study.

Itch is the commonest skin-related symptom, and sex differences are increasingly recognised as important determinants in stratified medicine, but only little is known about sex differences in itch. Questionnaire-based studies indicated that women perceive itch as more intensive and bothersome in comparison with men. However, data of studies using standardised itch models to objectify sex differences are scarce and inconsistent.

Smoking does not Alter the Therapy Response to Systemic Anti-psoriatic Therapies: A Two-country, Multi-centre, Prospective, Non-interventional Study.

Psoriasis can involve the skin, joints, nails and cardiovascular system and result in a significant impairment in quality of life. Studies have shown a lower response rate to systemic anti-psoriatic therapies in smokers, and smoking is a trigger factor for psoriasis. The aim of this study was therefore to analyse the response to systemic therapies for psoriasis, with a focus on smoking.

Implementation and evaluation of an algorithm for the management of scabies outbreaks.

Background: Infestations with scabies mites are a global burden affecting individuals of all ages, classes and ethnicities. As poor sanitation and overcrowding favor the transmission of this highly contagious disease, epidemic outbreaks are frequently observed among displaced persons and asylum seekers. Due to the growing influx of refugees during the last years, public health authorities in host countries are frequently confronted with the challenge to treat individuals with diagnosed or suspected scabies promptly and effectively to avoid further spreading of the infestation.

The Absence of Evidence is Evidence of Non-Sense: Cross-Sectional Study on the Quality of Psoriasis-Related Videos on YouTube and Their Reception by Health Seekers.

Background: Approximately 80% of internet users access health information online and patients with chronic illnesses especially rely on internet-based resources. YouTube ranks second among the most accessed websites worldwide and hosts an increasing number of videos with medical information. However, their quality is sometimes unscientific, misleading, or even harmful.

Good vibrations: Itch induction by whole body vibration exercise without the need of a pruritogen.

Mechanically induced itch is an important cofactor in many patients with chronic itch. However, studying mechanical itch in a controlled environment is challenging because it is difficult to evoke. We investigated the use of whole body vibration (WBV) exercise, a training method used for musculoskeletal rehabilitation, to experimentally evoke mechanical itch.

The human CIB1-EVER1-EVER2 complex governs keratinocyte-intrinsic immunity to β-papillomaviruses.

Patients with epidermodysplasia verruciformis (EV) and biallelic null mutations of (encoding EVER1) or (EVER2) are selectively prone to disseminated skin lesions due to keratinocyte-tropic human β-papillomaviruses (β-HPVs), which lack E5 and E8. We describe EV patients homozygous for null mutations of the gene encoding calcium- and integrin-binding protein-1 (CIB1). CIB1 is strongly expressed in the skin and cultured keratinocytes of controls but not in those of patients.

Epidermodysplasia Verruciformis: Inborn Errors of Immunity to Human Beta-Papillomaviruses.

Epidermodysplasia verruciformis (EV) is an autosomal recessive skin disorder with a phenotype conditional on human beta-papillomavirus (beta-HPV) infection. Such infections are common and asymptomatic in the general population, but in individuals with EV, they lead to the development of plane wart-like and red or brownish papules or pityriasis versicolor-like skin lesions, from childhood onwards. Most patients develop non-melanoma skin cancer (NMSC), mostly on areas of UV-exposed skin, from the twenties or thirties onwards.

Elucidating the genetic architecture of Adams-Oliver syndrome in a large European cohort.

Adams-Oliver syndrome (AOS) is a rare developmental disorder, characterized by scalp aplasia cutis congenita (ACC) and transverse terminal limb defects (TTLD). Autosomal dominant forms of AOS are linked to mutations in ARHGAP31, DLL4, NOTCH1 or RBPJ, while DOCK6 and EOGT underlie autosomal recessive inheritance. Data on the frequency and distribution of mutations in large cohorts are currently limited.

Exudate collection using wound sponges-An easy, non-invasive and reliable method to explore protease activities in ulcers.

Proteases are important for wound healing, but in excessive amounts or left uncontrolled, they may cause healing impairment or other severe wound complications. Point-of-care testing for protease activities in wounds may be useful for monitoring the effectiveness of treatment, and for early identification of wounds that potentially fail to heal. Here we describe an easy, noninvasive method to collect wound fluid for evaluating the protease milieu of wounds.

Papular Epidermal Nevus with "Skyline" Basal Cell Layer Syndrome - Natural Course: Case Report and Literature Review.

Papular epidermal nevus with "skyline" basal cell layer (PENS) is a very rare type of keratinocytic nevus and is associated with extracutaneous findings such as neurological symptoms in about 50% of the cases. Therefore, it is also referred to as PENS syndrome. Clinically visible hyperkeratotic papules and plaques already appear at birth or shortly thereafter, while neurological symptoms such as epilepsy and mental retardation manifest themselves during childhood.
