Abstract
The use of immunosuppressive drugs predisposes to infections, as they block the most important stage in antiviral defense, which is the cytotoxic T-lymphocyte HLA-dependent response. We report a case of extensive genital warts in a young woman on therapy for psoriasis with cyclosporine, afterwards successfully treated with an anti-tumor necrosis factor alpha (TNF-α) agent. Cyclosporine may predispose to the reactivation of latent infections and may favor the clinical manifestations of human papillomavirus (HPV)-related diseases, due to the inhibition of cell-mediated immunity that plays a crucial role in controlling HPV infections. In the literature the relationship between HPV and TNF-blockers has not yet been clearly defined. Our case underlines that the prompt interruption of cyclosporine can induce a complete regression of warts without any additional treatment and adds evidence to the possible use of anti-TNF-α in patients with psoriasis and genital warts.

Abstract
Psoriasis (PSO) is traditionally defined as an immune-mediated, inflammatory dermatological disease characterized by a chronic-relapsing course and associated with multifactorial inheritance (genetic predisposition and influence of various environmental factors). Considered until recently a dermatological disease only, today PSO is correctly known as a systemic one because of the involvement of multiple organs with important impact on social life and relationships. PSO is found in the 0.3-4.6% of the world's population, while its prevalence in the Italian population is estimated at 2.8%. Therefore, if we consider that in Tuscany more than 100,000 people out of 3,672,202 suffer of psoriasis, it is of paramount importance to focus on a shared clinical and therapeutic protocol to manage the disease. With the aim of ensuring diagnostic-therapeutic suitability, high levels of care and standardization of treatment, a unique clinical-therapeutic management model has been developed and validated in Tuscany, involving all accredited regional dermatological centers. Among the possible alternatives to be implemented in the treatment of patients with mild, moderate-severe psoriasis, UVBnb phototherapy is widely used alone or in association with other systemic and non-systemic devices. Despite this, there is still no universally shared therapeutic protocol. In this context the CO.FO.TO working group (Consensus Fototerapia Toscana) is born with the aim of defining and validating the main guidelines in the use of phototherapy with UVBnb in psoriasis; the guidelines are based both on the real-life experience of the different centers of reference in the region and on the revision of the recent literature.

Abstract
Patients with HIV infection are more likely to develop anogenital warts compared to HIV-negative people and are susceptible to treatment failures and recurrences. We report a case of extensive vulvar warts in an HIV-positive woman successfully treated with sinecatechins ointment. After the failure of a combination of cryotherapy and imiquimod 5% cream, we started therapy with sinecatechins 10% ointment. The patient developed an intense local inflammatory reaction after three weeks that induced the discontinuation of the therapy. After two weeks, we observed a complete regression of inflammation and a reduction of genital warts. The lesions completely regressed within a few weeks, with no relapse after eight months. Sinecatechins is a standardized extract of green tea leaves, effective in the treatment of external genital and perianal warts in immunocompetent patients, but their role has not been yet studied for immunocompromised people. Our case may represent a starting point for further studies, in order to evaluate the relation between treatment dosage, side effects, and drug response in immunocompromised patients.

Abstract
BACKGROUND Though the combination/collision of nevi or lentigo simplex and hemangiomas is frequent, the malignant collision tumor melanoma-hemangioma is exceptional and can sometime clinically simulate a benign collision. To date, a series of collision tumors of hemangiomas associated with either benign or malignant melanocytic skin lesions (MSL) has yet to be studied by non-invasive imaging and clinico-pathologic correlates. METHODS We present 10 cases of patients with collision tumors of hemangioma with different MSL including: 2 in situ lentigo-maligna melanoma, 1 invasive melanoma, 5 melanocytic nevi, and 2 lentigo simplex. The clinical aspect along with the dermoscopic and reflectance confocal microscopy (RCM) features is described and compared with histopathologic findings. RESULTS Dermoscopic examination allows to recognize a dark ring in malignant collision melanoma-hemangioma and a jelly ring sign in benign collision of nevi/lentigo simplex-hemangioma. These peculiar features were confirmed by RCM and histopathologic findings. CONCLUSION Two simple dermoscopic clues confirmed by RCM features can be proposed to help distinguish between benign and malignant collisions tumors.

Abstract
BACKGROUND UVA1 phototherapy is a valid therapeutic alternative for skin lymphoproliferative disorders, although there are few studies concerning its role in mycosis fungoides (MF). Our aim was to evaluate and confirm the effectiveness of UVA1 phototherapy in patients in early stage MF. METHODS We enrolled 12 patients, 9 males and 3 females (mean age 54.83±9.99, range 36-74) with a histological diagnosis of mycosis fungoides at early stage. All patients were treated with UVA1 for 22 sessions with two different protocols (3 times or 5 times per week) at the dose of 45 J/cm2. A punch biopsy was performed before and after the treatment, to evaluate the variation of histological features and of the proliferation index (Ki67/MIB1). RESULTS At the end of the study, we found a marked clinical improvement in all patients, associated to a statistically significant reduction of the proliferation index Ki67/MIB1. Five patients achieved a complete clinical and histological response, while six a partial one and only one a minimal response. CONCLUSIONS Although in recent years the number of the therapeutic options available for all types of skin lymphoproliferative disorders, in particular mycosis fungoides, has increased considerably, there are few studies concerning UVA1 phototherapy. Our results represent a starting point for further studies, in order to investigate the role that these UV-rays can play either alone or in combination with other therapeutic regimens.

Abstract
Purpose Eye involvement has long been appreciated in patients with chronic graft versus host disease (cGVHD). In particular, ocular complications are frequent and can be potentially severe in patients with steroid-refractory cGVHD, and therefore necessitate close monitoring. This prospective study was designed to describe eye manifestations of cGVHD in a large series of patients monitoring them before and after 1 year of extracorporeal photochemotherapy (ECP). ECP is a relatively new therapeutic approach based on the biological effects of psoralen 8-methoxypsoralen (8-MOP) and ultraviolet A light (UVA) on mononuclear cells collected by apheresis, and reinfused into the patient. Methods Only patients with steroid-refractory cGVHD under treatment with ECP, who developed cGVHD-related eye symptoms, were selected for the study. Ophthalmologic examination was repeated every 3 months. Only patients with complete recovery of the ocular manifestations and symptoms were considered responsive. Results In our study we observed eye alterations in 24 out of 140 patients (17%) with cGVHD. After 12 months of ECP, 10 out of 21 patients (48%) completely responded to the therapy. In all these cases the contribution of ECP was also essential in all the other organs subject to cGVHD. Conclusions Further studies are necessary to clarify the role of ECP in patients with cGVHD, especially in associated eye manifestations. Although our experience is limited, it suggests that ECP could be a safe and effective therapy for steroid-refractory eye manifestations of cGVHD.

SNHG5 promotes proliferation and induces apoptosis in melanoma by sponging miR-155. RSC Adv 2018; 8:6160-6168.

Abstract
Background: Melanoma is the most common malignancy of skin cancer. Small nucleolar RNA host gene 5 (SNHG5), a long non-coding RNA (lncRNA), has been demonstrated to be abnormally expressed in multiple malignances. However, the roles and molecular mechanisms of SNHG5 in melanoma progression have not been well identified. Methods: RT-qPCR assays were used to detect the expression patterns of SNHG5 and microRNA-155 (miR-155). Cell proliferation was assessed using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and colony formation assays. Cell apoptosis rate was measured by flow cytometry via double-staining of fluorescein isothiocyanate (FITC)-labeled annexin V (Annexin V-FITC) and propidium iodide (PI). The interaction between SNHG5 and miR-155 was validated using bioinformatics analysis, subcellular fraction assay, luciferase assay and RNA immunoprecipitation (RIP) assay. A mouse model of melanoma was established to further verify the effect of SNHG5 on tumor growth in vivo. Results: SNHG5 expression was upregulated in melanoma tumor tissues and cell lines. Moreover, higher SNHG5 expression was associated with advanced pathogenic status and poor prognosis. Functional analysis showed that SNHG5 knockdown suppressed proliferation and facilitated apoptosis in melanoma cells. Mechanical exploration revealed that SNHG5 acted as a molecular sponge of miR-155 in melanoma cells. Restoration experiments delineated that miR-155 down-regulation partly abrogated SNHG5-knockdown-mediated anti-proliferation and pro-apoptosis effect in melanoma cells. In vivo assays further demonstrated that SNHG5 depletion hindered tumor growth through up-regulating miR-155 expression. Conclusion: SNHG5 promoted the development of melanoma by sponging miR-155 in vitro and in vivo, implying the important implication of lncRNAs in melanoma progression and providing a potential therapeutic target for melanoma. Melanoma is the most common malignancy of skin cancer. Small nucleolar RNA host gene 5 (SNHG5), a long non-coding RNA (lncRNA), has been demonstrated to be upregulated in tumor tissues and cells of melanoma.![]()

Abstract
OBJECTIVE The colour of a nail polish varies according to the nail on which it is applied. The objective of this study was to predict the colour of the nail polish on a given nail and to study how the colour varies depending on the nail polish thickness. METHODS Six nail polishes were applied in one, two and three layers on the nails of one subject, thus forming eighteen samples. The spectral reflectances of the eighteen nail polishes applied on the nails with different thicknesses were obtained by spectrophotometry. The spectral reflectances of the nails without polish were also measured using the same technique. The thicknesses of nail polishes were measured by high-definition optical coherence tomography (HD-OCT). Then, to determine the physical parameters of the nail polish itself, we applied the six nail polishes on an opacity drawdown chart and we measured the spectral reflectance and the thickness of each patch using spectrophotometry and HD-OCT, respectively. The Kubelka-Munk theory was used to get the predicted spectral reflectance of the nail polish applied on the nail according to the polish thickness by knowing the parameter of the polish itself and the spectral reflectance of the nail. The predicted spectral reflectances were finally compared with those measured directly on the nails. RESULTS The predicted spectral reflectances were rather close to measured ones. Consequently, knowing the colour of the nail without polish and the optical parameters of the nail polish itself, we can estimate the colour of the nail polish applied on the nail depending on its thickness. CONCLUSION Our study showed that the Kubelka-Munk theory can be used to predict the nail polish colour. The ability to predict the real colour of a nail polish applied on a nail could help a nail polish manufacturer to improve his polish formulae in order to obtain a precise colour.

Abstract
Plaque-type blue naevus (PTBN) is a very rare variant of blue naevus (BN). The potential malignancy of subcutaneous cellular nodules (SCN) in PTBN was discovered in 2012, and there is currently no clear consensus on prognostic factors or management guidelines of such lesions. PTBN on the scalp have not been described in the literature. We report the clinical, histopathological and immunohistological features of a 50-year-old man who presented with a 30-year history of scalp PTBN, with malignant proliferation of nodular elements and fatal outcome 8 years later. This case suggests that long-term monitoring of patients with PTBN is required. Early surgical removal of such lesions should be considered, especially in the presence of any case of enlargement or change.

Abstract
Psoriasis is a chronic and relapsing inflammatory skin disease, clinically characterized by erythematous and scaly plaques. Treatment approach is mainly driven by disease severity, though several factors should be considered in order to identify the optimal therapeutic choice. Mild psoriasis may be treated with a wide array of topical agents including corticosteroids, vitamin D analogs, keratolytics, and calcipotriol/betamethasone propionate compound. Because guidelines may not provide practical indications regarding the therapeutic approach, the use of topical agents in psoriasis is more individually tailored. In order to homogenize the standard of care, at least in a local setting, we collected the real-life-based recommendations for the use of topical therapies from an expert panel, the Tuscany Consensus Group on Psoriasis, representing all leading centers for psoriasis established in Tuscany. With this document, this consensus group sought to define principles guiding the selection of therapeutic agents with straightforward recommendations derived from a real-life setting.

Abstract
BACKGROUND Inflammatory external root resorption is one of the possible complications of replantation of an avulsed tooth. Several studies have shown that limited FOV CBCT is an efficient diagnostic support and in treatment planning of these cases in paediatric patients because of its high resolution combined with low radiation doses. The recent literature has suggested that Biodentine is an effective material for resolution of inflammatory root resorption. CASE REPORT This article describes the successful therapy of a replanted tooth affected by inflammatory root resorption. In the present case, a CBCT exam was performed to detect the extent of the damage, and the canal was filled with Biodentine in the apical third. At present, the threated tooth is asymptomatic, and the twelve months follow-up examination showed healing of periradicular hard tissues.

Abstract
Extracorporeal photochemotherapy (ECP) has been used successfully for the treatment of chronic Graft versus Host Disease (cGvHD). However, the mechanism by which ECP exerts its protective effects remains elusive. Some recent observations have suggested a possible role of certain subsets of T lymphocytes with immunosuppressive properties (T-regulatory cells) that coexpress CD4 and high levels of the interleukin-2 receptor chain: CD4+CD25+ T lymphocytes. We studied whether ECP affects the percentage of these cells in the peripheral blood of patients with cGvHD. The study population consisted of 14 patients with cGvHD refractory to systemic steroids. On enrolment in each cycle of ECP, patients underwent clinical examination, blood chemistry analysis and other instrumental procedures to document and assess involvement of the various organs and systems. For cytofluorimetric identification and phenotyping of CD4+CD25+ T lymphocytes, peripheral blood samples were collected in EDTA anticoagulant before ECP, after 48 hours, and after 6 and 12 months from the start of treatment. The 14 patients in this study received a total of more than 300 cycles of ECP, with only minor side effects. The clinical outcome was negative in 2 patients and positive in 12 patients. Within-subject analysis indicated that the percentage of CD4+CD25+ T lymphocytes before ECP and after 12 months of treatment was significantly increased. Our study confirms that changes in the percentage of CD4+CD25+ T cells induced by ECP could be a central aspect in the cascade of immune events leading to the immunological and clinical effects of this treatment in patients with cGvHD.

A risk scoring system for the differentiation between melanoma with regression and regressing nevi. J Dermatol Sci 2016; 83:138-44.

Abstract
BACKGROUND Spontaneous regression of melanomas is relatively common, its prevalence ranging from 10 to 35%. However, regressing nevi can exhibit worrisome feature and simulate melanoma both clinically and dermoscopically. Thus, the presence of regression can represent a confounding factor. OBJECTIVE To investigate the frequency of dermoscopic patterns of "regression" in a series of benign and malignant melanocytic skin lesions, and to design an integrated scoring system. Scoring classifiers are very effective in selecting the significant parameters for discriminating two clinical conditions, thus can rapidly calculate a patient's risk for a given disease. METHODS We selected a series of 95 regressing melanocytic lesions, including 50 regressing nevi and 45 melanomas with regression. For each lesion, 12 dermoscopic variables (i.e. five types of regression structures, five atypical pigmentation structures, atypical vascular pattern and pink areas) were examined by three expert in dermoscopy (blinded to the histological diagnosis). The dermoscopic evaluation was then combined with patient age, gender, body site and the maximum diameter of lesion. Concordance analysis with Cohen's kappa was performed between the three clinicians. A risk scoring system was designed by the leave-one-out cross-validation procedure to ensure model prediction power. RESULTS The predictive score model revealed a sensitivity of 97.8% and a specificity of 75.5% in discriminating nevi and melanomas with regression. Using the score model, the diagnostic performance of the examiners increased by an average of 23.7% in sensitivity and 5.9% in specificity, compared with standard dermoscopic pattern analysis. CONCLUSIONS We assessed the validity of an integrated risk scoring model as a new methodological approach that could help the dermatologist in the differentiation between melanoma with regression and regressing nevus. Future studies could test the setting up of a score model over an even more complex pool of data obtained from different skin lesions with various diagnostic devices.

Abstract
Skin allografts from cadaver donors are an important resource for treating extensive burns, slow-healing wounds and chronic ulcers. A high level of cell viability of cryopreserved allografts is often required, especially in burn surgery, in Italy. Thus, we aimed to determine which conditions enable procurement of highly viable skin in our Regional Skin Bank of Siena. For this purpose, we assessed cell viability of cryopreserved skin allografts procured between 2011 and 2013 from 127 consecutive skin donors, before and after freezing (at day 15, 180, and 365). For each skin donor, we collected data concerning clinical history (age, sex, smoking, phototype, dyslipidemia, diabetes, cause of death), donation process (multi-tissue or multi-organ) and timing of skin procurement (assessment of intervals such as death-harvesting, harvesting-banking, death-banking). All these variables were analysed in the whole case study (127 donors) and in different groups (e.g. multi-organ donors, non refrigerated multi-tissue donors, refrigerated multi-tissue donors) for correlations with cell viability. Our results indicated that cryopreserved skin allografts with higher cell viability were obtained from female, non smoker, heartbeating donors died of cerebral haemorrhage, and were harvested within 2 h of aortic clamping and banked within 12 h of harvesting (13-14 h from clamping). Age, cause of death and dyslipidaemia or diabetes did not appear to influence cell viability. To maintain acceptable cell viability, our skin bank needs to reduce the time interval between harvesting and banking, especially for refrigerated donors.

Abstract
Dermatologists are often referred urgent cases of acral hematoma by general practitioners and sports medicine specialists for the purpose of excluding warts, nevi or melanoma. Acral hematoma is often a cause of anxiety to patients and their families. Here, we report a case of purpura traumatica pedis, referred to us as suspected plantar melanoma because of the finding of parallel-ridge pattern on dermatoscopic examination. To avoid unnecessary and costly procedures, doctors should inquire about any episode of physical exertion before the onset of purpura, recording the lesion’s anatomic site (e.g., unilateral vs. bilateral involvement) and clinical features.

Abstract
We report the case of a 37-year-old woman (phototype II) who presented at our outpatient clinic with a two-month history of hyperpigmented plantar macules. Medical history revealed that the patient had taken capecitabine in the past three months as adjuvant chemotherapy for recurrent breast cancer. Dermoscopic examination of the plantar macules showed parallel ridge pattern with pigmentation in the furrows without obliteration of eccrine gland apertures. Besides in acral melanoma, parallel ridge pattern can also be observed in benign plantar lesions, such as congenital or acquired acral nevi, subcorneal hemorrhage, dye-related pigmentation and drug-induced hyperpigmentation, especially in patients with phototypes III–VI. The few reported cases of capecitabine-induced hyperpigmentation have been associated with hand and foot syndrome in patients with phototypes IV–V and palmar as well as plantar involvement.

Abstract
Platelet-derived products have proven useful in accelerating healing processes and tissue regeneration. However, despite their widespread use in clinical practice, the cellular and molecular mechanisms involved have not yet been completely clarified. Recent studies show that interaction between platelet gel (PG) and peripheral blood mononuclear cells (PBMC) can result in activation of PBMC and production of several cytokines involved in wound healing and tissue repair. The aim of our study was to analyze whether crosstalk between platelets and PBMC can influence wound healing by modulating release of VEGF, bFGF and IL-10 by PBMC. Cultures of PBMC alone and co-cultures with autologous PG of 24 healthy volunteers were incubated under normoxia for 24 h. VEGF, bFGF and IL-10 concentration and expression were then analyzed in supernatants by ELISA and by real-time RT-PCR. We observed a down-regulation of VEGF and bFGF release and an up-regulation of IL-10 release in co-cultures of PBMC and PG. Platelets are not only important in the early stages of the healing process (clot formation, direct release of growth factors), but also can influence the whole process of tissue regeneration by modulating synthesis and release of VEGF, bFGF and IL-10 by PBMC. These effects could give platelets a new key role in the control of healing processes and provide insights into the clinical success of platelet-derived products in many medical fields.

Abstract
BACKGROUND Nicolaides-Baraitser and Coffin-Siris syndromes are emerging conditions with overlapping clinical features including intellectual disability and typical somatic characteristics, especially sparse hair, low frontal hairline, large mouth with thick and everted lips, and hands and feet anomalies. Since 2012, mutations in genes encoding six proteins of the BAF complex were identified in both conditions. METHODS AND RESULTS We have clinically evaluated a cohort of 1161 patients with intellectual disability from three different Italian centers. A strong clinical suspicion of either Nicolaides-Baraitser syndrome or Coffin-Siris syndrome was proposed in 11 cases who were then molecularly confirmed: 8 having de novo missense mutations in SMARCA2, two frame-shift mutations in ARID1B and one missense mutation in SMARCB1. Given the high frequency of the condition we set up a one-step deep sequencing test for all 6 genes of the BAF complex. CONCLUSIONS These results prove that the frequency of these conditions may be as high as the most common syndromes with intellectual deficit (about 1%). Clinical geneticists should be well aware of this group of disorders in the clinical setting when ascertaining patients with intellectual deficit, the specific facial features being the major diagnostic handle. Finally, this work adds information on the clinical differences of the two conditions and presents a fast and sensitive test for the molecular diagnosis.

Abstract
Infantile perianal pyramidal protrusion, it is a rare benign cutaneous condition described in relatively recent times. It is considered to be under-reported in the pediatric literature because it is often mistaken for other conditions. The unawareness of this lesion may be responsible for an excessive concern both in physician and in parents, which leads to overly aggressive and unnecessary treatments. Thus its recognition has many implications regarding proper management and treatment. We report a typical presentation of IPPP in which the diagnosis was based on the use of non-invasive diagnostic tools and in particular of dermoscopy and ultrasonography.
