  • A pilot study of the UVA-photoprotective potential of dehydrosilybin,
           isosilybin, silychristin, and silydianin on human dermal fibroblasts
    • Abstract: 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 silymarinʼs 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. Their effects on reactive oxygen species (ROS), carbonylated proteins and glutathione (GSH) level, caspase-3 activity, single-strand breaks’ (SSBs) formation and protein level of matrix metalloproteinase-1 (MMP-1), heme oxygenase-1 (HO-1), and heat shock protein (HSP70) were evaluated. The most pronounced preventative potential was found for DHSB, a minor component of silymarin, and SC, the second most abundant flavonolignan in silymarin. They had significant effects on most of the studied parameters. Meanwhile, a photoprotective effect of SC was mostly found at double the concentration of DHSB. ISB and SD protected against GSH depletion, the generation of ROS, carbonylated proteins and SSBs, and caspase-3 activation, but had no significant effect on MMP-1, HO-1, or HSP70. In summary, DHSB and to a lesser extent other silymarin flavonolignans are potent UVA-protective compounds. However, due to the in vitro phototoxic potential of DHSB published elsewhere, further studies are needed to exclude phototoxicity for humans as well as to confirm our results on human skin ex vivo and in vivo.

  • Seasonal variation in the internet searches for psoriasis
    • Abstract: 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. The cosinor analysis demonstrated a statistically significant seasonal pattern of searches for [psoriasis] in the United Kingdom (p < 0.001), Canada (p = 0.002), Ireland (p < 0.001), Australia (p < 0.001), and New Zealand (p < 0.001), and a trend towards a seasonal variation in searches in the United States (p = 0.079), with the zenith in late winter/early spring and through in late summer/early fall. A zenith in late winter/early spring and valley in late summer/early fall presented an approximately 6-month difference between hemispheres. Public interest in seeking psoriasis information through internet searches displayed a seasonal pattern, with the highest interest in the late winter/early spring. If a more comprehensive study validated the association of psoriasis flares with patterns in online searches, beyond investigating only seasonality in public interest, the internet data could be used to guide public health interventions and to manage the care of patients with psoriasis.

  • Alterations in the inflammatory cells infiltrating basal cell carcinomas
           during immunocryosurgery
    • Abstract: Immunocryosurgery, the combination modality of a cryosurgery session at day 14 of a 5-week daily imiquimod treatment cycle, has shown remarkable efficacy in the treatment of basal cell carcinoma (BCC). The modality was designed to exploit synergy of antitumor effects, including the induction of immune responses, elicited by imiquimod and cryosurgery. Herein, we report on the infiltration of the BCC by selected inflammatory cell species during an immunocryosurgery treatment cycle. The density of tissue infiltrating CD68+, CD3+ and Foxp3+ cells was studied by immunohistochemistry in 56 BCC biopsies from 28 treated sites (26 patients) at baseline and at days 12, 16 or 28 during treatment. Immunocryosurgery induces statistically significant alterations in all three cell species (p < 0.003): The density of CD68+ increased already by day 12 and remained at a higher level during the treatment thereafter. The density of CD3+ cells increased significantly between days 12 and 16 of treatment. The density of Treg (Foxp3+) cells increased in the early phase of treatment (highest at day 12) to decrease significantly already 2 days after the cryosurgery session (day 16) and thereafter up to day 28 of the treatment cycle (p = 0.033). Within the tumor tissue, these alterations result in an abrupt increase in the CD3+/Foxp3+ ratio, a finding suggesting that the cryosurgical perturbation may probably play a decisive modulating role in the cellular composition of the inflammatory infiltrate during immunocryosurgery, eventually heralding the induction of an effective tumor-destructing immune response.

  • Development and evaluation of a vegetable oil blend formulation for
           cutaneous wound healing
    • Abstract: 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. VOB resulted in faster and greater re-epithelialization in the in vivo excisional wounds, exhibiting significant wound area reduction of 8.9, 8.0, 35.1, 45.2 and 47.0% after 2, 5, 10, 14 and 21 days post-wounding, respectively, when compared with the vehicle control. Histological and biochemical analyses showed that the VOB-treated wounds exhibited a significant increase of granular tissue and controlled inflammatory response by modulation of the release of pro-inflammatory cytokines TNF-α, IL-6 and IL-1. Moreover, VOB-treated wounds showed a significant and concrete increase in the deposition and organisation of collagen fibres in the wound site and improved the quality of the scar tissue. Altogether, these data revealed that VOB accelerates wound healing processes and might be beneficial for treating wound disorders.

  • Extracutaneous involvement of pyoderma gangrenosum
    • Abstract: 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. As with any other ND, extracutaneous involvement may also occur preceding, during, or following the appearance of skin lesions. Sterile neutrophilic infiltrates have been found to affect internal organs supporting the concept of PG being a systemic disease, with lung being the most common extracutaneous manifestation followed by ocular and visceral compromise. Therefore, in this review, we describe the current knowledge of extracutaneous involvement of PG and its respective clinical manifestations to aid dermatologists in diagnosis, management, and determining prognosis.

  • The prevalence of ADH1B and OPRM1 alleles predisposing for alcohol
           consumption are increased in the Hungarian psoriasis population
    • Abstract: 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. Multiple logistic regression analyses were implemented. Analysis revealed association between C allele of the rs1229984 polymorphism (ADH1B gene) and psoriasis risk (ORadditive = 1.58, 95% CI 1.23–2.03, p < 0.001, ORrecessive = 1.58, 95% CI 1.22–2.04, p = 0.001). Furthermore, the G allele of rs1799971 polymorphism (OPRM1 gene) increased the risk of familial aggregation (ORadditive = 1.99, 95% CI 1.36–2.91, p < 0.001 ORdominant = 2.01, 95% CI 1.35–3.01, p < 0.001). In subgroups of psoriatic patients with history of early onset and familial aggregation effect allele ‘C’ of rs1229984 showed association in the additive and recessive models (ORadditive = 2.41, 95% CI 1.26–4.61, p < 0.01, ORrecessive = 2.42, 95% CI 1.26–4.68, p < 0.01). While effect allele ‘G’ of rs1799971 (OPRM1) also associated with increased risk of early onset and familial aggregation of psoriasis in the additive and dominant models (ORadditive = 1.75, 95% CI 1.27–2.43, p = 0.001, ORdominant = 1.82, 95% CI 1.26–2.63, p = 0.001). Our results suggest that genetically defined high-risk individuals for alcohol consumption are more common in the psoriasis population.

  • Retrospective study of immediate postoperative electron radiotherapy for
           therapy-resistant earlobe keloids
    • Abstract: 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. The first fraction of adjuvant radiotherapy was administered within 2 h of surgery, and the other two sessions were completed within the next day or two. Five (16.7%) primary keloids and 25 (83.3%) recurrent keloids were examined in this study. The primary endpoint was the local control rate, which was 86.7% after a median follow-up of 26 months (14–93 months). Secondary endpoints were acute and late procedure-related complications, and no severe complications were observed after combination therapy. Our results suggest that three-fraction electron radiotherapy after excision within 2 days of surgery is a safe and effective protocol for the prevention of earlobe keloid recurrence that can also improve patient compliance and comfort.

  • Carboxyethyl aminobutyric acid (CEGABA) lacks cytotoxicity and
           genotoxicity and stimulates cell proliferation and migration in vitro
    • Abstract: 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. Flow cytometry and the scratch-wound assay were used to assess cell-cycle phase distributions and cell migration rates. Compared with the untreated control, CEGABA increased cell growth 1.6 times after 72 h, independent of dose. The compound also decreased cell replication time by 4 h. These findings seem to be related with the approximately 1.5-times increase in phase S cells numbers. Importantly, in vitro wound healing improved roughly 20% after treatment with CEGABA for 24 h and persisted after 48 h, indicating culture recovery. The time-dependent proliferation and migration of fibroblasts induced by CEGABA besides the fact that the compound is neither genotoxic nor cytotoxic makes it an ideal candidate in the development of cosmeceuticals in antiaging therapy.

  • Comparison of physical and mental functioning among moderate-to-severe
           psoriasis patients on biologic versus oral therapy
    • Abstract: 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). Physical and mental functioning were measured with the Short Form-12 version 2 (SF-12v2) Physical Component Summary (PCS) and Mental Component Summary (MCS), respectively. The mean PCS score among patients on biologic therapy was significantly higher than that of patients on oral therapy (46.25 [95% CI 43.91–48.59] versus 42.39 [95% CI 41.05–43.73]; P < 0.01). The mean MCS score among patients on biologic therapy was also significantly higher than that of patients on oral therapy (52.46 [95% CI 50.51–54.41] versus 50.19 [95% CI 49.00–51.38]; P < 0.05). Based on adjusted multiple linear regression, biologic therapy was associated with a significantly greater increase in measures of physical functioning (P < 0.05) and mental functioning (P < 0.001) as compared to oral therapy. In conclusion, clinicians need to account for physical and mental health when making treatment decisions. Biologic therapy is associated with significantly greater increases in measures of physical and mental functioning when compared to oral therapy in the US adult psoriasis population.

  • Medical malpractice cases involving lack of access to dermatologists for
           incarcerated patients in the United States from 1982 to 2018
    • Abstract: While prison medicine is a heavily researched area for quality improvement, little is known regarding prisoner access to dermatologists. The goal of this study was to characterize the claims related to a lack of dermatologist access in prison malpractice cases. We searched the LexisNexis Academic database of legal records from 1970 to 2018 using the terms “medical malpractice and dermatologist” to yield federal malpractice cases involving dermatologists. Ultimately, 89 distinct cases in which a prisoner was not able to see a dermatologist were included in the final analysis. Data relating to year, location, anatomical site, symptoms, dermatologist related claim, specialty of treating physician, and final diagnosis were extracted for each case. The 89 cases involving prisoners who were not able to see a dermatologist for their skin condition ranged from 1982 to 2018, with California (n = 12) and Pennsylvania (n = 11) containing the largest number of cases. 76% of the prisoners were only treated by primary care prison physicians for their dermatologic concerns. Several issues regarding dermatologist access were categorized in this study. This study reveals limited access to dermatologists for prisoners in need of dermatologic care. Improved collaboration between prison officials, prison medical staff, and dermatologists could help improve prisoner care and limit malpractice risk.

  • Stem cells in aesthetic dermatology: bioethical and professional
           obligations
    • Abstract: Recently, stem cells in aesthetics have attracted increased attention, especially as they have become a popular trend that is being mass-marketed to consumers on the Internet and social media. Unfortunately, studies have shown this marketing to be misleading as it portrays many purported benefits of stem cells that have yet to be proven in the limited studies that are available. It is important for clinicians to understand the evidence and marketing behind any new trends, especially in the fast-paced world of aesthetics, where treatments often outpace current medical understanding. As clinicians, we have bioethical and professional obligations to educate ourselves on current trends, ensure adequate patient safety, and advocate for continued consumer education.

  • Carrier oils in dermatology
    • Abstract: Wounds are a common medical infliction. With the increase in microbial resistance and a shift of interest towards complementary medicines, essential oils have been shown to be beneficial in suppressing microbial growth. However, in practice, essential oils are more often diluted into a base due to the risk of topical adverse effects, such as dermatitis. There is a lack of collated evidence-based information on toxicity and efficacy of carrier oils. The current information on the subject matter is restricted to generic, aroma-therapeutic books and pamphlets, based on anecdotal evidence rather than an experimental approach. Therefore, this review aimed at identifying the recommended carrier oils used in dermatology and thereafter collating the scientific evidence to support the use of carrier oils together with essential oils recommended for dermatological use. Aloe vera gel had multiple studies demonstrating the ability to enhance wound healing; however, several other carrier oils have been largely neglected. It was observed that the extracts for certain plant species had been used to justify the use of the carrier oils of the same plant species. This is an inaccurate cross assumption due to the difference in chemical composition and biological activities. Lastly, despite these carrier oils being recommended as a base for essential oils, very little data was found on the interactive profile of the carrier oil with the essential oil. This review provides a platform for further studies, especially if essential oils are to receive credence in the scientific field.

  • Unravelling effects of relative humidity on lipid barrier formation in
           human skin equivalents
    • Abstract: Relative humidity (RH) levels vary continuously in vivo, although during in vitro generation of three-dimensional human skin equivalents (HSEs) these remain high (90–95%) to prevent evaporation of the cell-culture medium. However, skin functionality is directly influenced by environmental RH. As the barrier formation in HSEs is different, there is a need to better understand the role of cell-culture conditions during the generation of HSEs. In this study, we aim to investigate the effects of RH on epidermal morphogenesis and lipid barrier formation in HSEs. Therefore, two types of HSEs were developed at 90% or at 60% RH. Assessments were performed to determine epidermal morphogenesis by immunohistochemical analyses, ceramide composition by lipidomic analysis, and lipid organization by Fourier transform infrared spectroscopy and small-angle X-ray diffraction. We show that reduction of RH mainly affected the uppermost viable epidermal layers in the HSEs, including an enlargement of the granular cells and induction of epidermal cell activation. Neither the composition nor the organization of the lipids in the intercorneocyte space were substantially altered at reduced RH. In addition, lipid processing from glucosylceramides to ceramides was not affected by reduced RH in HSEs as shown by enzyme expression, enzyme activity, and substrate-to-product ratio. Our results demonstrate that RH directly influences epidermal morphogenesis, albeit the in vitro lipid barrier formation is comparable at 90% and 60% RH.

  • PUVA-induced pityriasis lichenoides chronica-like papular lesions in
           patients with mycosis fungoides: a clinical, histopathological and
           immunohistochemical study
    • Abstract: Mycosis fungoides (MF) is the most common form of cutaneous T cell lymphoma (CTCL) with many clinical variants including papular and pityriasis lichenoides chronica (PLC)-like variants. During psoralen and ultraviolet A (PUVA) treatment of MF, PLC-like papular lesions were observed to appear. The exact nature of these lesions is not fully understood. This work aimed to study PLC-like papular lesions arising in MF patients receiving PUVA therapy clinically, histopathologically and immunohistochemically (using monoclonal antibodies against CD4 and CD8) and to compare them with lesions in classic PLC patients. Fifteen MF patients with PLC-like papular lesions arising during PUVA treatment were included and 15 patients with classic PLC served as controls. While the extent of these lesions significantly correlated with their duration (p < 0.05), it showed no significant correlation with the TNMB stage of MF, number of phototherapy sessions or cumulative UVA dose at which they started to appear. The response status of MF to PUVA did not affect their development. Compared to classic PLC, these lesions showed significantly more acute onset (p = 0.003). None of these lesions showed histopathological features essential to diagnose papular/PLC-like MF and no significant difference existed with regard to their histopathological and CD4/CD8 phenotypic features compared to classic PLC. Papular lesions mimicking PLC in MF patients receiving PUVA mostly represent an upgrading reaction with possible good prognostic implication.

  • Down-regulation of tissue levels of serine protease inhibitor (vaspin) in
           psoriasis vulgaris patients: a possible mechanism of narrowband
           ultraviolet B radiation
    • Abstract: Vaspin is a serine protease inhibitor of the serpin family which has an anti-inflammatory effect. It has an important role in the pathogenesis of some inflammatory diseases such as psoriasis. There are no previous studies comparing the effect of narrowband ultraviolet B (NB-UVB) radiation on tissue vaspin levels in psoriasis. So we aimed in this case–control study to estimate the possible role of vaspin in the pathogenesis of psoriasis, and to evaluate the effect of NB-UVB radiation on tissue vaspin in psoriasis. This study included 21 non-obese patients with moderate psoriasis and 20 non-obese clinically healthy age and sex matched controls. Patients underwent 24 sessions of NB-UVB radiation. A 4 mm punch skin biopsy was taken from all patients before and after treatment and from the controls for estimation of tissue vaspin level by enzyme-linked immunosorbent assay. Vaspin levels was significantly lower in patients before NB-UVB (99.72 pg/mg ± 12.11 pg/mg) compared to controls (257.34 pg/mg ± 28.11 pg/mg) with (P < 0.001). In addition, high significant difference was detected between vaspin levels in patients before (99.72 pg/mg ± 12.39 pg/mg) and after NB-UVB (190.92 pg/mg ± 27.61 pg/mg) with (P < 0.001). In conclusion, improvement of psoriatic plaques by NB-UVB is associated with an upregulation of tissue vaspin levels. Therefore, we suggest that vaspin has an important role in psoriasis pathogenesis.

  • Successful intra-class switching among IL-17 antagonists: a multicentre,
           multinational, retrospective study
    • Abstract: 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. After 12 weeks of treatment, patients’ PASIs were evaluated. Treatment success was defined as reaching PASI 75 after 12 weeks. Topical treatment was allowed and used in all patients. 26 patients were included (13 male, 13 female) and 29 switches were evaluated. Overall, 29 switches in 21 patients were evaluated. 18 patients changed their therapy from secukinumab to ixekizumab, or in 7 cases to brodalumab. Brodalumab was used in 3 cases after failure of treatment with ixekizumab. Only in one case, non-response of brodalumab resulted in a therapy switch to secukinumab. In 15 (52%) cases, PASI 75 was reached. In 6 (20%) patients, the switch led to a PASI 50 response. No success of treatment was seen among 8 (28%) participants. When patients fail to respond or do not tolerate an IL-17 blocker, switching to another anti-IL-17A/RA is a promising viable option. Larger studies are needed to confirm our results.

  • Lectin-like transcript 1 (LLT1) expression is associated with nodal
           metastasis in patients with head and neck cutaneous squamous cell
           carcinoma
    • Abstract: 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. The estimator of Fine and Gray was used to estimate the cumulative incidence curves for relapse. Proportional Hazard models and Hazard ratios (HRs) were used for studying the risk of tumor relapse and mortality. LLT1 strong expression was a significant risk factor for nodal metastasis with crude and adjusted ratios (HRs) of 3.40 (95% CI 1.39–9.28) and 3.25 (95% CI 1.15–9.16); and for cSCC specific death of 6.17 (95% CI 1.79–21.2) and 6.10 (95% CI 1.45–25.7). Strong LLT1 expression is an independent predictor of nodal metastasis and poor disease-specific survival and it might be helpful for risk stratification of patients with cSCC.

  • Liver fatty acid-binding protein might be a predictive marker of clinical
           response to systemic treatment in psoriasis
    • Abstract: 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. Serum FABP1 concentrations were analyzed by the enzyme-linked immunosorbent assay. Statistical analysis was performed for correlation of FABP1 with anthropometric, metabolic or inflammatory indices and treatment used. Serum liver-type FABP levels were significantly increased in psoriatic patients compared to the controls (p < 0.001). No statistical correlations between FABP1 and PASI (p = 0.25) was noted, however patients with severe psoriasis had the highest level of FABP1. No significance with metabolic parameters was obtained, beside a positive significant relation with BMI after therapy (p = 0.03). Liver-type FABP significantly correlated with CRP (p = 0.01) and morphotic blood elements. Systemic treatment combined resulted in significant decrease of FABP1 (p = 0.04), regardless of the drug: p = 0.1 in acitretin group, p = 0.3 in methotrexate group. Liver-type FABP might be a novel marker of psoriasis and predictor of clinical response to systemic therapy. FABP1 could be involved in CMDs risk assessment and perhaps link psoriasis with hematological disorders.

  • From pathogenesis of acne vulgaris to anti-acne agents
    • Abstract: Acne vulgaris is a cutaneous chronic inflammatory disorder with complex pathogenesis. Four factors play vital roles in acne pathophysiology: hyperseborrhea and dysseborrhea, altered keratinization of the pilosebaceous duct, Cutibacterium acnes (C. acnes) and inflammation. The main hormones responsible for the development of acne vulgaris include androgens, insulin and insulin-like growth factor-1. Other factors involved in this process are corticotropin-releasing hormone, α-melanocyte-stimulating hormone and substance P. Wnt/β-catenin signaling pathway, phosphoinositide 3-kinase (PI3K)/Akt pathway, mitogen-activated protein kinase pathway, adenosine 5′-monophosphate-activated protein kinase pathway and nuclear factor kappa B pathway participate in the modulation of sebocyte, keratinocyte and inflammatory cell (e.g. lymphocytes, monocytes, macrophages, neutrophils) activity. Among all the triggers and pathways mentioned above, IGF-1-induced PI3K/Akt/Forkhead box protein O1/mammalian target of rapamycin (mTOR) C1 pathway is the most important signaling responsible for acne pathogenesis. Commonly used anti-acne agents include retinoids, benzoyl peroxide, antibiotics and hormonal agents (e.g. spironolactone, combination oral contraceptive and flutamide). New approaches including peroxisome proliferator-activated receptor γ modifier, melanocortin receptor antagonists, epigallocatechin-3-gallate, metformin, olumacostat glasaretil, stearoyl-CoA desaturase inhibitor omiganan pentahydrochloride, KDPT, afamelanotide, apremilast and biologics have been developed as promising treatments for acne vulgaris. Although these anti-acne agents have various pharmacological effects against the diverse pathogenesis of acne, all of them have a synergistic mode of action, the attenuation of Akt/mTORC1 signaling and enhancement of p53 signal transduction. In addition to drug therapy, diet with no hyperglycemic carbohydrates, no milk and dairy products is also beneficial for treatment of acne.

  • Association of dermatomyositis with systemic and opportunistic infections
           in the United States
    • Abstract: 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. Overall, dermatomyositis was associated with serious infections in adults (multivariable logistic regression; adjusted odds ratio [95% confidence interval]: 2.19 [2.08–2.30]) and children (1.45 [1.20–1.76]). In particular, dermatomyositis was significantly associated with 32 of 48 and 15 of 48 infections examined in adults and children, respectively, including infections of skin, bone, joints, brain, heart, lungs, and gastrointestinal system, as well sepsis, antibiotic-resistant and opportunistic infections. Predictors of infections included non-white race/ethnicity, insurance status, history of long-term systemic corticosteroid usage, Cushing’s syndrome (likely secondary to corticosteroid usage), diabetes, and cancer. Serious infections were associated with significantly increased inpatient cost and death in dermatomyositis patients. In conclusion, dermatomyositis is associated with higher odds, costs and inpatient mortality from serious and opportunistic infections.
