Chronic hand eczema is a common chronic inflammatory skin disease that influences public health. Staphylococcus aureus colonization plays important roles in chronic hand eczema morbidity and progression, which also correlated to chronicity and severity of the disease. In this multicenter clinical trial, we aim to investigate the relationship between S. aureus colonization and chronic hand eczema. Eighty patient volunteers diagnosed with chronic hand eczema in 4 hospitals from 4 cities participated in this study...

Recent studies have noticed significant role of interleukin (IL)-17, 22, 23, Foxp3, interferon-gamma (IFN-γ) and Wnt5a in oral and cutaneous lichen planus (LP). This study was undertaken to assess whether similar expression exists in lichen planus pigmentosus (LPP). We recruited 30 patients of treatment-naïve 'LPP' (in absence of cutaneous/mucosal LP elsewhere, group 1), 10 patients having active treatment-naïve cutaneous 'LP' (group 2), 10 patients having 'post-LP' hyperpigmentation (in absence of active LP and off treatment for at least past 3 months, group 3), and 10 controls...

WNT/β-catenin signaling pathways play a pivotal role in the human immune defense against infections and in chronic inflammatory conditions as psoriasis. Wnt gene alterations are linked to known comorbidities of psoriasis as obesity, diabetes and Crohn's disease. The objective of this study was to investigate WNT7B, WNT10B, WNT16 and TCF7L2 gene and protein expression in lesional and non-lesional skin and in the peripheral blood of patients with chronic plaque psoriasis compared with healthy individuals. To investigate the effect of narrowband UVB radiation, expression of these genes were analyzed before and after narrowband UVB treatment...

Alopecia areata (AA) is an autoimmune disease associated with high levels of proinflammatory cytokines. Since chronic inflammation plays a major role in the pathogenesis of insulin resistance, AA can theoretically increase the risk of diabetes. We sought to investigate this theory by conducting a case-control study. Sixty patients with alopecia areata and 60 healthy volunteers (matched for age, sex, and body mass index) were evaluated. Fasting blood glucose (FBS), C-peptide, plasma insulin, and homeostasis model assessment for insulin resistance (HOMA-IR) were measured for each individual...

Cosmeceuticals are cosmetics formulated using compounds with medical-like benefits. Though the antiaging effect of carboxyethyl aminobutyric acid (CEGABA) has been discussed, its action mechanism in cosmeceuticals remains unclear. This study assessed the in vitro efficacy and safety of CEGABA. NHI-3T3 mouse fibroblast cell line was treated with two CEGABA concentrations (50 and 500 μmol/L) for 24 h, 48 h, and 72 h. Cytotoxicity and genotoxicity were evaluated by colorimetry (MTT) and the alkaline version of the comet assay, respectively...

The exposure of naked unprotected skin to solar radiation may result in numerous acute and chronic undesirable effects. Evidence suggests that silymarin, a standardized extract from Silybum marianum (L.) Gaertn. seeds, and its major component silybin suppress UVB-induced skin damage. Here, we aimed to investigate the UVA-protective effects of silymarin's less abundant flavonolignans, specifically isosilybin (ISB), silychristin (SC), silydianin (SD), and 2,3-dehydrosilybin (DHSB). Normal human dermal fibroblasts (NHDF) pre-treated for 1 h with flavonolignans were then exposed to UVA light using a solar simulator...

Retronychia is a condition, first described in 1999, characterized by the embedding of the proximal nail plate into the proximal nail fold and the stacking of a multiple generations of nail plates beneath the proximal nail fold. The disease affects frequently the toenails and is associated with stress-relevant situations including repetitive trauma, ischemic etiologies, postpartum, and compartment syndrome. Predisposing factors including static disorder of the feet may be underestimated. The paucity of data regarding the predisposing factors is because existing studies are limited to small case reports, case series, and retrospective studies...

Keloid resection followed by adjuvant radiotherapy is the most efficacious treatment for keloids. However, for earlobe keloids, an optimal protocol for the total dose and fractions of adjuvant radiation has not yet been established. We retrospectively analyzed the efficacy and safety of immediate three-fraction electron radiotherapy after operation for resistant earlobe keloids. From 2011 to 2017, three-fraction electron radiotherapy with single dose of 5 Gy was given postoperatively to 23 patients with 30 keloids in our hospital...

Some researches with different designs investigated the seasonal pattern of psoriasis; however, the seasonal variation in public interest in psoriasis has not yet been examined. The monitoring of internet search activity has increasingly been used to gain insights into public interest in health-related topics. The aim of the investigation is to employ the Google Trends datasets to evaluate whether a seasonal trend exists in the internet searches of psoriasis by the general public. In the observational investigation, the Google Trends was queried for the [psoriasis] in the United States, the United Kingdom, Canada, Ireland, Australia, and New Zealand between January 2004 and December 2018...

With the extensive variety of available treatments for psoriasis, it is paramount that clinicians understand the differences between therapies. A critical literature gap exists regarding the effects of different systemic therapies on physical and mental functioning in the US psoriasis population. We sought to compare the impact of biologic versus oral therapy on measures of physical and mental functioning among US adults with moderate-to-severe psoriasis. We performed a nationwide, cross-sectional study of 2,431,282 (weighted) (183 non-weighted) US adults with psoriasis on biologic or oral therapy using the 2003-2015 Medical Expenditure Panel Survey (MEPS)...

Alcohol intake affects in great the symptoms and life of  psoriasis patients, although the association of SNPs related to increased alcohol consumption with psoriasis has not been elucidated. Therefore, to investigate the association of psoriasis with established alcohol consumption and dependence-related gene variants we conducted a population-based case-control study including 3743 subjects (776 psoriasis cases and 2967 controls from the general Hungarian population). Genotyping of 23 SNPs at ADH1B, ADH1C, ALDH1A1, ALDH2, SLC6A3, DDC, GABRA2, GABRG1, HTR1B, MAOA, TPH2, CHRM2, GRIN2A, POMC, OPRM1, OPRK1 and BDNF were determined and differences in genotype and allele distributions were investigated...

This work aimed to evaluate the in vivo capacity of a vegetable oil blend formulation (VOB) developed to accelerate cutaneous wound closure. Total thickness wounds were punctured on the skin on the back side of each animal and topically treated with the VOB formulation, Dersani® ointment or the vehicle control. After 2, 7, 14, 21 days post-wounding, five animals from each group were euthanized, and the rates of wound closure and re-epithelialization were evaluated. The wounds were harvested for histological and biochemical analysis...

Hair loss affects men and women of all ages. Dermal papilla (DP) plays a crucial role in regulating the growth and cycling of hair follicles. Lactoferrin (LF) exhibits a wide range of biological functions, including antimicrobial activity and growth regulation. However, its effect on DP and its role in hair growth remain unknown. In this study, we found that bovine LF (bLF) promoted the proliferation of DP cells and enhanced the phosphorylation of Erk and Akt. The bLF-mediated proliferation was significantly blocked by the Erk phosphorylation inhibitor PD98059 or the Akt phosphorylation inhibitor LY294002...

Previous studies have identified neuron navigator 2(NAV2) as an oncogene in several human tumors. However, the NAV2 gene expression changes and its role in the pathogenesis of cutaneous melanoma have not been clearly illustrated. Further investigations of NAV2 in cutaneous melanoma may provide new mechanistic insight and treatment strategy for this disease. Through immunohistochemistry assay and bioinformatics analysis, we found that melanoma tissues showed an upregulated expression of NAV2 which correlated with poor prognosis of cutaneous melanoma...

Fatty acid-binding proteins play an inconclusive role in lipid metabolism and cardiometabolic diseases (CMDs) which are closely related with psoriasis. Aim of the study was to investigate the diagnostic value of serum liver fatty acid-binding protein (FABP1) level and associations with disease severity, inflammation or metabolic parameters and influence of systemic treatment in psoriatic patients. The study included thirty-three patients with active plaque-type psoriasis and eleven healthy volunteers. Blood samples were obtained before and after 12 weeks of therapy with methotrexate and acitretin...

The interaction of lectin-like transcript 1 (LLT1) with CD161 inhibits Natural Killer cell activation. Overexpression of LLT1 contributes to the immunosuppressive properties of tumor cells. However, there are little data about LLT1 expression in human solid tumors. The objective of this paper is to investigate the relationship between LLT1 expression with the clinicopathologic features and its impact on the prognosis of head and neck cutaneous squamous cell carcinoma (cSCC). LLT1 expression was analyzed on paraffin-embedded tissue samples obtained from 100 patients with cSCC by immunohistochemistry...

Patients with dermatomyositis have multiple risk factors for serious and opportunistic infections, including immune dysregulation, long-term systemic corticosteroid treatment and comorbid health conditions. We sought to determine whether dermatomyositis is associated with increased odds and burden of systemic, opportunistic and antibiotic-resistant infections. We analyzed data from the Nationwide Inpatient Sample from 2002 to 2012, containing a cross-sectional representative 20% sample of all hospitalizations in the US...

Pyoderma Gangrenosum (PG) is an inflammatory neutrophilic dermatosis (ND) associated with underlying chronic inflammation and/or malignancy. Diagnosis remains to be challenging as a gold standard diagnostic test is lacking. Initial manifestations may include papules, vesicles, or pustules that subsequently develop into ulceration with features of undermining and violaceous borders. Timely recognition of pyoderma gangrenosum is impeded by clinical findings shared with other etiologies, such as granulomatosis with polyangiitis, polyarteritis nodosa, and antiphospholipid syndrome...

IL-17 blockers are among the newer anti-psoriatic treatment options and little is known about the interclass switching. We have thus initiated a multi-center, multi-national, retrospective study to assess the treatment response of patients who were switched from one IL-17 blocker to another. Analysis consisted of data from patients with moderate-to-severe psoriasis who did not respond satisfactorily to one of the available IL-17 blockers (secukinumab, ixekizumab, brodalumab) and were subsequently switched to another drug of this class...
