Abstract
INTRODUCTION Sweat secretion is controlled by the sympathetic nervous system and is less active during winter than in the summer. Raynaud's phenomenon is affected by an excessive strain of the sympathetic nerves after exposure to a cold environment, thus reducing the quality of life of patients with collagen disease. Herein, we focus on the eccrine sweat glands that receive both adrenergic and cholinergic innervation. Our hypothesis is that excessive activation of sympathetic nerve in Raynaud's phenomenon can affect sweating, especially in winter. This study is designed to evaluate the neuroactive sweating responses in patients with collagen disease and to assess its association with skin findings in peripheral circulatory disorders. METHODS AND ANALYSIS The study will be conducted at a single centre in Japan. Patients with systemic sclerosis, Sjogren's syndrome, systemic lupus erythematosus, mixed connective tissue disease, and dermatomyositis will be assessed using the quantitative sudomotor axon reflex test. The primary outcomes will be sweat volume and reaction time due to axon reflex and the Raynaud's condition score. The secondary outcomes will include patient background, skin symptoms (digital ulcers, pernio-like eruptions, subcutaneous calcifications, telangiectasia, nailfold capillary dilatation/bleeding and degree of skin sclerosis) and skin surface temperature. Evaluation will be done two times, during the summer and winter, allowing for the assessment of seasonal differences in sweating responses. ETHICS AND DISSEMINATION Ethical approval of this study was certified by the clinical research review board of Nagasaki University Hospital (Reference number: CRB19-001). We will disseminate the findings of this study through peer-reviewed publications and conference presentations. TRIAL REGISTRATION NUMBER jRCTs072190009; pre-results.

Abstract
BACKGROUND Keloid lesions are characterized by mesenchymal cell proliferation and excessive extracellular matrix deposition. Previous microarray analyses have been performed to investigate the mechanism of keloid development. However, the molecular pathology that contributes to keloid development remains obscure. AIM To explore the underlying essential molecules of keloids using microarrays. METHODS We performed microarray analyses of keloid and nonlesional skin tissues both in vivo and in vitro. Gene expression levels were compared between tissues and cells. Quantitative reverse transcription (qRT)-PCR and immunohistochemical staining were used to determine the expression levels of molecules of interest in keloid tissues. RESULTS Several common molecules were upregulated in both keloid tissues and keloid-lesional fibroblasts. PTPRD and NTM were upregulated both in vivo and in vitro. The genes MDFI and ITGA4 were located at the centre of the gene coexpression network analysis using keloid tissues. qRT-PCR revealed significant expression levels of PTPRD and MDFI in keloid tissues. Immunopathological staining revealed that MDFI-positive cells, which have fibroblast characteristics, were located in the keloid-associated lymphoid tissue (KALT) portion of the keloid tissue. CONCLUSION Our gene expression profiles of keloids could distinguish the difference between lesional tissue and cultured lesional fibroblasts, and MDFI was found to be commonly expressed in both tissues and cells. Thus, MDFI-positive cells, which were located in the KALT, may play an important role in keloid pathogenesis and thus might be useful for in vitro keloid studies.

Abstract
Hit, Lead & Candidate Discovery Antiangiogenesis therapy is a promising way for treatment of solid cancers, and many angiogenesis inhibitors that target vascular endothelial growth factor (VEGF) or its receptors have been developed. We explored novel antiangiogenic compounds other than anti-VEGF drugs by screening our synthetic compound library and found that 6-thiophen-3-yl-2-methoxy-1,4-naphthoquinone (6-TMNQ) had potential as a novel angiogenesis inhibitor. This paper describes the effects of 6-TMNQ on angiogenesis and tumor growth in vitro and in vivo. 6-TMNQ inhibited serum-, VEGF-, and basic fibroblast growth factor (bFGF)-stimulated proliferation of endothelial cells in a concentration-dependent manner, but had no effect on the proliferation of fibroblasts. VEGF-induced activation of VEGF receptor-2 in endothelial cells was not affected by the compound. 6-TMNQ markedly abrogated both migration and tube formation of endothelial cells. Orally administered 6-TMNQ inhibited angiogenesis in response to VEGF or bFGF in mice in a dose-dependent manner. Furthermore, when tumor-bearing mice were treated with 6-TMNQ, increase in tumor size was significantly prevented due to inhibition of angiogenesis in the tumor tissues. These results demonstrate that 6-TMNQ is an orally available compound that selectively inhibits endothelial cell proliferation and migration, and abrogates angiogenesis, resulting in the prevention of tumor growth. The mechanism of 6-TMNQ action is different from that of conventional anti-VEGF drugs.

Abstract
This is the report from the fifth meeting of the Harmonising Outcome Measures for Eczema initiative (HOME V). The meeting was held on 12-14 June 2017 in Nantes, France, with 81 participants. The main aims of the meeting were (i) to achieve consensus over the definition of the core domain of long-term control and how to measure it and (ii) to prioritize future areas of research for the measurement of the core domain of quality of life (QoL) in children. Moderated whole-group and small-group consensus discussions were informed by presentations of qualitative studies, systematic reviews and validation studies. Small-group allocations were performed a priori to ensure that each group included different stakeholders from a variety of geographical regions. Anonymous whole-group voting was carried out using handheld electronic voting pads according to predefined consensus rules. It was agreed by consensus that the long-term control domain should include signs, symptoms, quality of life and a patient global instrument. The group agreed that itch intensity should be measured when assessing long-term control of eczema in addition to the frequency of itch captured by the symptoms domain. There was no recommendation of an instrument for the core outcome domain of quality of life in children, but existing instruments were assessed for face validity and feasibility, and future work that will facilitate the recommendation of an instrument was agreed upon.

Abstract
Background and objectives Itch is one of the major symptoms in dermatology clinics, and severely impairs the quality of life. Itch is frequently produced by environmental stimuli, especially heat or warmth. Changes of temperature on the skin surface and noxious heat stimuli augment and develop itch, respectively. Thermally provoked itch is sometimes intractable with existing treatments. Data bases and data treatment Recent researches, linking heat sensation and itch, were searched in MEDLINE literature database through PubMed. Results Recent studies of the transient receptor potential cation channel subfamily vanilloid type 1 (TRPV1), the calcitonin gene‐related peptide (CGRP) and the vesicular glutamate transporter 2 (VGLUT2), which link noxious heat and itch, contribute to a much better understanding of the thermally evoked itch process. From a clinical perspective, a warm sensation is a major provocative factor for subjects with atopic dermatitis. The accumulation of artemin (also known as enovin or neublastin) in the dermis of lesional skin can possibly provide a pathological mechanism for warmth‐provoked itch. Conclusions This mini‐review describes recent results of both basic and clinical research related to thermally provoked itch.

Abstract
Differential diagnosis of cutaneous T cell lymphoma (CTCL) and severe atopic dermatitis (AD) is often difficult because of the similarity in their skin manifestations. However, such differentiation is extremely important because of the differences in remedy and prognosis. The aim of this study was to investigate new, helpful diagnostic aids for distinguishing CTCL from AD. The frequency of forkhead box protein 3(+) (FoxP3(+)) regulatory T cells (T(regs)) in cutaneous lesions was evaluated among the three populations. Serum-soluble interleukin-2 receptor (sIL-2R), immunoglobulin (Ig)E-radioimmunosorbent test, lactate dehydrogenase (LDH) and blood eosinophil count were measured in 11 CTCL patients (including three CTCL patients misdiagnosed previously with intractable AD), 10 adult AD patients and nine psoriasis patients. The frequency of T(regs) was increased significantly in cutaneous lesions of AD compared with those of CTCL. Serum IgE and LDH levels were also elevated significantly in AD compared with CTCL, whereas there were no significant differences in serum sIL-2R levels between CTCL and AD. In the three CTCL patients who were misdiagnosed with intractable AD, IgE and LDH levels were lower than in AD patients, whereas serum sIL-2R levels were as high as in AD patients and higher than in the other eight CTCL patients. The higher frequency of T(regs) in the cutaneous lesions of patients with AD than in those with CTCL and higher serum IgE and LDH levels in patients with AD than in those with CTCL might be helpful reference values for the differential diagnosis of these two diseases.

Abstract
Acanthosis nigricans (AN) is a hyperpigmented keratotic skin lesion known to be associated with malignant disease and endocrinopathy. We report a very rare case of generalized AN with Sjögren's syndrome- and systemic lupus erythematosus-like features but without type B insulin resistance. Neither internal malignancy nor other endocrinological disorders, including glucose intolerance, were detected during a 10-year clinical course with benign diffuse papillomatosis extending from the mucosa of the larynx to the esophagogastric junction. The case was complicated with chronic thyroiditis and interstitial pneumonia, which were not treated with any medication. AN skin lesions and mucosal papillomatosis regressed with oral cyclosporine A, accompanied by the lowering of autoantibody titers. This is the first report of generalized AN involving an area from the mucosa of the larynx to the esophagogastric junction accompanied by autoimmune manifestations which responded to systemic immunosuppressive therapy.

Abstract
Thymoma-associated multi-organ autoimmunity is a rare, autoimmune disease that causes colitis, liver dysfunction and cutaneous graft-versus-host (GVH)-like skin damage. This paraneoplastic autoimmune disorder may be due to inadequate T cell selection in the tumour environment of the thymus. Although sporadic case reports have revealed its clinical features, little is known about its pathological mechanism. By comparing the skin-infiltrating T cell subsets with those of GVH disease (GVHD) and other inflammatory skin diseases, we sought to elucidate the pathological mechanism of thymoma-associated multi-organ autoimmunity. Histopathological and immunohistochemical analysis of skin biopsies was performed for three patients with thymoma-associated multi-organ autoimmunity. Histopathological findings of thymoma-associated multi-organ autoimmunity were indistinguishable from those of patients with acute GVHD, although the aetiologies of these diseases are completely different. The frequency of regulatory T cells (T(regs)) is reduced in cutaneous lesions and CD8+ cytotoxic T lymphocytes that massively infiltrate into the epidermis of patients with thymoma-associated multi-organ autoimmunity. Additionally, the ratio of T helper type 17 (Th17) cells to CD4+ cells in patients with thymoma-associated multi-organ autoimmunity and acute GVHD was higher than that in healthy controls, but similar to that in psoriasis vulgaris patients. Similarity of the skin-infiltrating T cell subsets with those of acute GVHD suggested that skin damage in patients with thymoma-associated multi-organ autoimmunity might be induced by self-reactive cytotoxic T lymphocytes under the diminished suppressive capacity of T(regs).

Abstract
BACKGROUND Mast cell-derived histamine is known to act on dermal fibroblasts and contribute to formation of an intractable chronic allergic dermatitis. Although this fibrotic event may also occur in other organs such as the nasal mucosa, no direct evidence has been reported as to whether responsiveness to histamine by fibroblasts derived from different organs is of the same intensity. Furthermore, while type 1 histamine receptor (H1R) blockers have been shown to be effective for alleviation of the symptoms of allergic diseases, their ability to affect histamine-induced tissue remodeling has not yet been clarified. OBJECTIVE Our aim was to study the effect of H1R-blockers on histamine-induced tissue remodeling. METHODS A macroarray assay was used for a comprehensive analysis of histamine-induced gene expression by normal human fibroblasts. Fibroblasts derived from skin or nasal mucosa were cultured in the presence of various concentrations of histamine, and the synthesis of type 1 collagen was measured by means of semi-quantitative reverse-transcriptase polymerase chain reaction and enzyme-linked immunosorbent assay. To determine the effect of H1R blockers, diphenhydramine hydrochloride and emedastine difumarate were investigated in this assay. RESULTS Histamine induced expression of various kinds of fibrogenic molecules in fibroblasts. Increased type 1 collagen expression was observed in fibroblasts treated with high-dose (0.1 mM to 1 microM) and low-dose (1 pM) histamine. This histamine-induced type 1 collagen synthesis was effectively diminished by emedastine difumarate. While organ specificity seems to be involved, emedastine difumarate is considered to be an effective drug for reversal of such histamine-induced remodeling in the skin. CONCLUSIONS We found that the expression of fibroblast-derived genes is differentially regulated by different concentrations of histamine and that the robustness of the inhibitory action of H1R blockers is different for skin-derived and nasal mucosa-derived fibroblasts. We believe that our findings may contribute to a better understanding of the mechanisms of histamine-induced tissue remodeling and provide information useful for the management of refractory allergic dermatitis.

Abstract
Non-Herlitz junctional epidermolysis bullosa (JEB-nH), a nonlethal variant of junctional epidermolysis bullosa (JEB), is an autosomal recessive disorder characterized by separation of the dermal-epidermal junction. JEB-nH is caused by mutations in several genes and lack of the COL17A1 gene product may lead to skin fragility. A 41-year-old Japanese man with JEB-nH, featuring mutations in the gene encoding type XVII collagen, presented with great blisters over his entire body accompanied by severe itching and eosinophilia usually observed in bullous pemphigoid (BP). To our knowledge, our patient is the first with JEB-nH to be treated successfully with an oral steroid to control his skin affliction, symptoms and eosinophilia. This suggests that in the case of JEB-nH with eosinophilia caused by some secondary immune activation, oral steroids may constitute an alternate therapy to improve aggravated skin conditions and severe itching, both of which tend to show resistance to usual dermatological treatments.

Abstract
Fourteen patients with malignant tumor in the head and neck region were treated with infusion of carboplatine microcapsules (CBDCA-mc) via percutaneous super-selective catheterization. A microcatheter was advanced into a feeding artery using a coaxial catheter system. Eleven patients had over 30% reduction of the tumor size on CT within 1 month after embolization. Twelve patients had an increased amount of low attenuation tissue in the tumor on CT after embolization, suggesting increased necrosis in the tumor. No definite hematologic toxicity was found. A majority of patients complained of moderate pain in the embolized region immediately after embolization, easily relieved by i.v. analgesics. Chemoembolization using CBDCA-mc may be an effective therapeutic modality in advanced cases of head and neck cancer.

Abstract
To achieve targeted distribution of anticancer drugs with sustained activity, ferromagnetic ethylcellulose microcapsules containing an anticancer drug, mitomycin C (FM-MMC-mc), were prepared by a method based on phase separation principles. Two prototypes of FM-MMC-mc were made: one with the drug as the core and zinc ferrite on its capsular surface (outer type); the other with both the drug and zinc ferrite as the core (inner type). Both preparations provided a sustained-release property and a sensitive response to conventional magnetic force, although certain differences in the release rate of drug, magnetic responsiveness, and particle size were found between the two dosage forms. Animal studies showed that the magnetic microcapsules could be magnetically controlled in the artery and urinary bladder. VX2 tumors in the rabbit hind limb and urinary bladder were successfully treated with magnetic control of FM-MMC-mc. Pharmacokinetic study revealed that the targeting of the microcapsules markedly enhanced the drug absorption into the surrounding tissues for a prolonged period of time. The results indicate the feasibility and effectiveness of the magnetic microcapsules as a targeted drug delivery system.
