OBJECTIVE: Profoundly increased mortality rates in schizophrenia, largely caused by a higher risk and earlier onset of cardiovascular disease, remain a major challenge. During the human lifespan, advanced glycation end products (AGEs) accumulate, and their concentration is strongly linked to cardiovascular mortality. AGE accumulation can be accelerated by several pathways, including oxidative stress. METHODS: From March 2015 through January 2016, a case-control study including 111 patients with a recent-onset psychosis, 135 controls from a validation cohort, and 286 healthy controls was performed...

Corynebacterium pseudotuberculosis is a Gram-positive, pleomorphic, facultative intracellular pathogen that causes Oedematous Skin Disease (OSD) in buffalo. To better understand the pathogenic mechanisms of OSD, we performed a comparative genomic analysis of 11 strains of C. pseudotuberculosis isolated from different buffalo found to be infected in Egypt during an outbreak that occurred in 2008. Sixteen previously described pathogenicity islands (PiCp) were present in all of the new buffalo strains, but one of them, PiCp12, had an insertion that contained both a corynephage and a diphtheria toxin gene, both of which may play a role in the adaptation of C...

BACKGROUND: Metastatic melanoma is still one of the most prevalent skin cancers, which upon progression has neither a prognostic marker nor a specific and lasting treatment. Proteomic analysis is a versatile approach with high throughput data and results that can be used for characterizing tissue samples. However, such analysis is hampered by the complexity of the disease, heterogeneity of patients, tumors, and samples themselves. With the long term aim of quest for better diagnostics biomarkers, as well as predictive and prognostic markers, we focused on relating high resolution proteomics data to careful histopathological evaluation of the tumor samples and patient survival information...

Transcription factor binding, chromatin modifications and large scale chromatin re-organization underlie progressive, irreversible cell lineage commitments and differentiation. We know little, however, about chromatin changes as cells enter transient, reversible states such as migration. Here we demonstrate that when human progenitor keratinocytes either differentiate or migrate they form complements of typical enhancers and super-enhancers that are unique for each state. Unique super-enhancers for each cellular state link to gene expression that confers functions associated with the respective cell state...

BACKGROUND: Psoriasis (PsO) is a multifactorial chronic and relapsing skin disease that affects about 125 million people in the world. Several studies have demonstrated the link between adipose tissue, inflammation, and PsO. The purpose of our study is to evaluate hypodermal adipose tissue inflammation underneath PsO plaques quantifying tissue elasticity with sonoelastography before and after treatment. The study was conducted at the Department of Dermatology of the University of "Rome Tor Vergata" and Department of Radiology of the University of "Rome Tor Vergata...

Xuesheng Han, Tory L Parker
The effect of cinnamon (Cinnamomum zeylanicum) bark essential oil (CBEO) on human skin cells has not been elucidated. Therefore, we investigated the activity of a commercially available CBEO in a validated human dermal fibroblast system, a model of chronic inflammation and fibrosis. We first evaluated the impact of CBEO on 17 protein biomarkers that play critical roles in inflammation and tissue remodeling. The impact of CBEO on genome-wide gene expression was also evaluated. CBEO showed strong anti-proliferative effects on skin cells and significantly inhibited the production of several inflammatory biomarkers, including vascular cell adhesion molecule-1, intercellular cell adhesion molecule-1, monocyte chemoattractant protein-1, interferon gamma-induced protein 10, interferon-inducible T-cell alpha chemoattractant, and monokine induced by gamma interferon...

N Spindler, C Josten, S Langer
Aim: Partial fasciectomy in cases of grade III-IV Dupuytren's contracture and coverage of the defect with local flaps. Indication: Dupuytren's contracture is a progressive disease of the hand associated with the formation of fascial cords, which may result in flexion and adduction contractures of the fingers leading up to complete dysfunction of the hands. Method: If several fingers are affected, partial fasciectomy is the gold standard in the treatment of Dupuytren's contracture. Ideally, the fingers reach the neutral position after the fibres causing the contracture are resected and arthrolysis is performed as needed...

REVIEW
H Stege, J Krutmann
Actinic keratosis is one of the most common skin diseases. Because of the ongoing demographic changes, it is anticipated that the incidence will further increase. Prevention of actinic keratoses is thus of great importance. By far the most important cause of actinic keratoses is the chronic cumulative irradiation of human skin with ultraviolet B and A radiation from natural sunlight. There is no doubt that use of sunscreens is effective in preventing actinic keratoses. Recent studies indicate that in high-risk groups the regular use of medical devices which are characterized by a very high SPF and which contain liposomally encapsulated DNA repair enzymes are effective in preventing the development of new actinic keratoses even when field cancerization is already present in human skin...

The ε4 allele of the APOE gene encoding apolipoprotein E (apoE) is a strong genetic risk factor for aging-related cognitive decline as well as late-onset Alzheimer's disease (AD) compared to the common ε3 allele. In the central nervous system, apoE is produced primarily by astrocytes and functions in transporting lipids including cholesterol to support neuronal homeostasis and synaptic integrity. Although mouse models and corresponding primary cells have provided valuable tools for studying apoE isoform-dependent functions, recent studies have shown that human astrocytes have distinct gene expression profile compare with rodent astrocytes...

BACKGROUND: Atopic dermatitis (AD) is the most common chronic inflammatory skin disease. A complex interaction of both genetic and environmental factors is thought to contribute to the disease. Recently relations between single nucleotide polymorphisms (SNPs) of toll-like receptors (TLRs) and AD have been reported. AIMS: The aim of the study was to evaluate whether SNPs in the TLR2 gene c.2258C>T (R753Q) (rs5743708) and TLR2 c.-148+1614T>A (A-16934T) (rs4696480) (NM_0032643) are associated with AD in Turkish children...

Dermoscopy is a method of growing significance in the diagnoses of dermatological pigmented skin diseases. However, in my case, mycology culture was negative and successful treatment was given on the basis of trichoscopy and wood lamp examination. I hereby describe a young boy with tinea capitis, multiple "comma hairs" and "zigzag hair" and a subtle additional feature "Morse code-like hair" when intensification was applied. Dermatoscopic aspects found skin Type 2 in a child of as a distinctive dermoscopic finding...

Extramammary Paget's disease is a rare cutaneous, intraepithelial adenocarcinoma involving primarily the epidermis but occasionally extending into the underlying dermis. The condition typically presents as a red, velvety, pruritic skin rash of the vulva region which closely mimics a multitude of other, more common conditions. As a result, vulvar Paget's disease is frequently misdiagnosed, leading to an often lengthy lag time (an average of about 2-3 years) between the onset of symptoms and diagnosis.

BACKGROUND: Vasculitis represents a specific pattern of inflammation of the blood vessel wall that can occur in any organ system of the body. The neutrophil to lymphocyte ratio (NLR) and red blood cell distribution width (RDW) are currently used as markers of inflammation in several diseases. OBJECTIVES: This study analyzed C-reactive protein level (CRP), erythrocyte sedimentation rate (ESR), white blood cell (WBC), NLR, and RDW in patients who had cutaneous vasculitis, or cutaneous vasculitis with systemic involvement, and in healthy controls...

Monogenic autoinflammatory diseases are a heterogeneous emergent group of conditions that are currently under intensive study. We review the etiopathogenesis of these syndromes and their principal manifestations. Our aim is to propose a classification system based on the clinicopathologic features of typical skin lesions for routine clinical use in dermatology. Our focus is on diagnosis in pediatric practice given that this is the period when the signs and symptoms of these syndromes first appear. In Part 1 we discuss the course of urticaria-like syndromes, which include cryopyrin-associated periodic conditions and hereditary periodic fever syndromes...

BACKGROUND: Aggregated amyloid-β peptide 1-42 (Aβ42), derived from the cellular amyloid precursor protein, is one of the pathological hallmarks of Alzheimer's disease (AD). Although active immunization against Aβ42 peptide was successful in AD mouse models and led to removal of plaques and improved memory, a similar clinical trial in humans (Aβ42 peptide immunization with QS-21 adjuvant) was stopped in phase II, when 6% of the treated patients developed encephalitis. Currently ongoing passive immunizations with the injection of preformed monoclonal antibodies against different epitopes within the Aβ1-42 peptide, which do not lead to activation of the immune system, have shown some effects in slowing AD pathology...

OBJECTIVES: The current study addressed the hypothesis that the local decrease in endothelin-1 (ET-1) bioavailability during sustained flow increases contributes to endothelium-dependent, flow-mediated dilatation (FMD) of conduit arteries and is altered in presence of cardiovascular risk factors. METHODS AND RESULTS: In nine young healthy individuals, the decrease in local ET-1 plasma levels and radial artery FMD in response to hand skin heating (from 34 to 44 °C) was not affected by endothelin type A (ETA) receptor blockade, achieved using the brachial infusion of BQ-123 (100 nmol/min per l of forearm), as compared with physiological saline (0...
