Introduction: Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease with systemic inflammation and high impact on quality of life. Treatment strategies are still inadequate with a lack of inflammation biomarkers. We conducted a prospective study to assess the correlation between serum amyloid A (SAA) levels and active lesion count; disease severity; Dermatology Life Quality Index (DLQI); smoking; BMI; and lesion sites. Methods: Forty-one patients (M/F: 22/19) were enrolled. Demographic, clinical, laboratory, and therapeutic data were assessed at baseline on patients not under treatment or in wash-out from systemic treatment for at least 2 weeks. Associations were investigated by univariate and multivariate analyses. Results: SAA levels were significantly associated with number of nodules (p = 0.005), abscesses (p < 0.001), fistulas (p = 0.016), and severe IHS4 (p = 0.088 and r = 0.514). Gluteal localization was correlated with high values of mSartorius and severe IHS4. Conclusions: We recommend assessment of SAA levels to monitor therapeutic response in patient with HS in order to prevent disease’s flare and potential complications.

Introduction. Dubowitz syndrome is a rare genetic disease with only a few cases reported in the literature. It is characterized by growth retardation, microcephaly, facial dysmorphism and higher risk of developing cancer and cardiomyopathies. PG is an autoinflammatory disorder that causes painful ulcers to develop on the skin and has not been previously associated with Dubowitz syndrome. Case Presentation. The authors report the case of a 50-year-old female with Dubowitz syndrome who developed painful ulcerative lesions. An incisional biopsy was performed to rule out other diagnoses, and a subsequent clinical diagnosis of PG was made. The patient was treated with specialized wound dressings and oral glucocorticoids. The clinical picture improved consistently after 7 weeks of therapy. Conclusions. This case report, to the authors’ knowledge, is the first to suggest a possible association between Dubowitz syndrome and PG and also to indicate an effective treatment.

There is a strong interaction between the immunological and nervous system in the skin. Lesions that are physically disfiguring and chronically relapsing have a high impact on quality of life (QoL) and can result in the emergence of psychiatric disorders. The literature data confirm a higher prevalence of psychiatric disorders in patients with psoriasis, hidradenitis suppurativa (HS) and atopic dermatitis (AD), but such data are compromised by low-quality evidence due to methodological heterogeneity.The primary aim was to analyse the prevalence of psychiatric comorbidities in a group of psoriasis, AD and HS patients compared with a control group. The secondary aims were to evaluate the impact of psychiatric comorbidities on the disease development, severity, flare-ups and QoL.A total of 59 cases and 64 controls were included.Generalized anxiety disorder and depressive disorder with anxious distress were found to be risk factors for AD. Age, smoking and substance-related disorder showed a specific association with HS. Major depressive disorder showed a specific association with dermatology life quality index (DLQI) and all the above disease flare-ups.Atopic dermatitis, psoriasis and HS are associated with psychiatric disorders. A psychodermatological approach improves outcomes in terms of QoL, disease flare-ups and long-term management.

Purpose of Review The compression therapy provides valuable support during management of vascular and inflammatory lower leg skin disorders. The review outlines the mechanism of action and the treatment options available with indications for use in wound management and general dermatology. Recent Findings Atypical wounds such as pyoderma gangrenosum, cutaneous vasculitis and other inflammatory skin diseases may benefit from the use of compression therapy. Adherence to treatment is always a challenging aspects for patients and caregiver, but modern technologies and specific materials have improved the compliance during treatment. Summary Compression therapy is a main option in vascular ulcer management. The technology provided by different devices together with new methods of bandaging application have increased the outcomes and acceptability from patients. Physicians should be aware of the advantages provided by compression therapy in skin diseases.

It is increasingly recognized that stakeholder views can be essential to ascertain the credibility of those entrusted with protection of the public and workers against radiation risks, the robustness of the approaches to protection and the relevance of research underpinning radiation protection. The CONCERT European Joint Programme of radiation protection research included consideration of stakeholder views. These were surveyed by means of a publicly available survey that was made available in fifteen languages to help encourage responses from a wide range of European countries. The survey ran in 2017 and received some 1961 responses over many countries, though response rates varied widely between countries. The survey respondents were largely highly educated with many having a professional connection to radiation protection or the use of radiation in medicine or industry. Survey results indicated a high level of scientific/technical knowledge relevant to radiation protection and indicated a general trust of most actors involved in the radiation protection field, perhaps unsurprisingly given the nature of the sampled population. Most expressed a reasonable level of satisfaction with the information available to them on radiation risk, but there is clearly room for improvement. Additionally, the survey identified potential training needs amongst the groups responding. It is concluded that, while the survey results are limited by the non-representativeness of the respondents by comparison with the EU population as a whole, it has been successful in gaining insights into areas where communication could be improved, where professional training gaps are present and where research could help to build wider trust in radiation protection.

Treatment of chronic leg ulcers remains a major challenge and it is a substantial financial burden on individuals, families, caregivers, and health care system. There is increasing evidence on using of autologous Platelet-rich-plasma in wound repair but limited clinical data are available on the efficacy and safety of the use of umbilical cord blood platelet gel (CBPG). In our pilot study, for the first time, we aimed to evaluated the safety and efficacy of the use of umbilical CBPG combined with a hydrogel dressing in 10 patients with chronic venous ulcers (VU). The protocol consisted of application of umbilical cord blood platelet-rich plasma (PRP) combined with a Carboxymethyl cellulose (CMC)-based hydrogel dressing once a week for 4 weeks. The 80% of patients after 4 weeks of treatment had a significantly decrease in wound size. Moreover, we obtained an improvement in terms of mean Wound Bed Score (WBS), numeric rating scale (NRS) value and the EQ-5D index score. This pilot study showed that the topically therapeutic administration of umbilical CBPG associated with a CMC-based hydrogel dressing has the potential to accelerate the healing of chronic lesions without adverse reaction. However, additional studies with larger sample size and longer follow-up periods are required to confirm our findings.

The main aim of this study is to evaluate the correspondence between the ultrasonographic thickness and the Breslow thickness in melanoma using ultra-high frequency ultrasound and the intra- and inter-operator repeatability in the ultrasonographic measurements of melanoma depth. Moreover, we propose a new protocol based on a combined ultrasonographic-histopathological approach.We analyzed 27 melanomas in a population consisted of 27 patients (mean age 57.6 years, 51.8% males), who came at the Department of Dermatology (University of Pisa, Pisa, Italy) from April 2016 to March 2018 and had an ultrasonographic examination of a suspected lesion before the surgical removal using ultra-high frequency ultrasound (Vevo®MD, Fujifilm, Visualsonics, Toronto, Canada; 70 MHz probe). B-mode images were analyzed by two skilled and blinded operators, and the maximum depth of the lesions was measured using a dedicated graphical user interface developed in Matlab R2016b (MathWorks Inc., Natick, MA), to obtain repetitive measurements.All melanomas appeared as band-like or oval/fusiform shaped hypoechoic inhomogeneous lesions. We observed an excellent agreement between the Breslow thickness of melanomas and the ultrasonographic thickness, as well as a reduced intra- and inter-operator variability in the ultrasonographic measurements of melanoma depth.We propose a ultrasonographic-histopathological protocol which may help clinicians to reduce the diagnostic delay, improve prognosis and survival rates, perform a surgical excision with negative margins, and reduce the variability in the assessment of Breslow thickness.

Traditional high-frequency ultrasound (HFUS; 20 MHz) is a non-invasive method used to study skin in vivo but is not able to measure skin thickness accurately and to identify the dermal-epidermal junction (DEJ). Ultra-high frequency ultrasound (UHFUS; 70-100 MHz) has sub-millimetre resolution comparable to histology. The aim of this study was to identify, by UHFUS, the DEJ and to describe skin differences in healthy individuals by providing a measure of skin thickness, based on age and gender. We also described the bullous pemphigoid lesion. We enrolled 42 patients divided into 2 groups: A and B. Group A included 32 healthy volunteers aged 22-74 years. Group B consisted of 10 patients with bullous pemphigoid. For each patient in group A, 8 ultrasound (US) clips by 70 MHz probe were performed at forehead, cheek, nose, forearm, abdomen, chest, back and leg. For each patient in group B, 5 US images were acquired at blisters roofs and edges. In each US image, we measured thickness of stratum corneum (α-β), epidermis (α-γ) and epidermis plus dermis (α-δ). In both groups, we found the presence of 4 lines delimiting: the stratum corneum (the layer between α-line and β-line), the epidermis (distance between α- and γ-line), and the boundary between dermis and subcutis (δ-line). The γ-line corresponds to the point of detachment of the bullae. The abdominal α-β layer was thicker in males (p = 0.019) and α-δ thickness at cheeks (p 0.001), chest (p = 0.007), back (p = 0.025) and forearm (p 0.001). In females, α-γ thickness of the back was greater (p = 0.005). In old people compared to young, we noticed an increase of α-β layer at forehead and chest (p = 0.014), an increase of α-γ layer at forearm (p = 0.001), back (p = 0.024) and leg (p = 0.010) and an increase of α-δ layer at forehead (p = 0.001) and nose (p = 0.049). UHFUS is an advanced imaging technique that can detect both the DEJ and the boundary between dermis and subcutaneous tissue so that epidermal and dermal thickness can be measured with good accuracy. Regarding gender and age, skin differences obtained with UHFUS were comparable to other non-invasive methods.

This article summarizes the main epidemiologic and diagnostic features of seborrheic keratosis-like (SK-like) melanoma. We performed a review of the current literature. The real and current incidence and prevalence of SK-like melanoma are unknown. Many lesions are misdiagnosed and not excised with histopathologic confirmation, or excised without an appropriate surgical approach due to a benign clinical and dermoscopic appearance. SK-like melanoma presents both melanoma and SK features. SK-like melanoma and SK are often clinically indistinguishable even for experienced dermatologists. Clinically, it develops as a black-dark brown or light slightly elevated, papule, nodule or plaque with rapid growth and a regular or irregular shape. SK-like melanoma presents melanocytic and nonmelanocytic dermoscopic features. Irregular dark-brown dots/globules, a blue-grayish veil, streaks, irregular pigmentation or network and brown lines point to a melanoma diagnosis. Among the nonmelanocytic features, milia-like cysts and comedo-like openings have been highlighted. The association of polarized and nonpolarized dermoscopic techniques is more accurate for studying the dermoscopic features of SK-like melanoma. If the dermoscopic features are unclear, further investigations with reflectance confocal microscopy (RCM) or biopsy with histologic examination are essential. SK-like melanoma is a dermatologic challenge. Careful clinical and dermoscopic evaluation favor a correct diagnosis. In unclear cases, it is important to perform a biopsy with histologic examination to confirm the correct diagnosis.

Introduction. Squamous cell carcinoma (SCC) is the second most prevalent malignant skin carcinoma. Bone infiltration is uncommon, and invasion of the dura mater and brain parenchyma is rare and possible only in the advanced stages of the disease. Treatment of advanced SCC is challenging and often requires the collaboration of a multidisciplinary team to provide local and systemic treatment. Management of advanced SCC of the scalp involving bones and meninges with brain exposure was described herein. Case Report. An 85-year-old male presented with advanced SCC of the scalp. A vegetative and infiltrating neoplastic ulcer of the frontal and parietal regions with exposure of the brain and extensive meningeal and bone destruction was observed. Because of comorbidities and decisions made by the patient and his family, he did not undergo immunotherapy, radiotherapy, or other invasive treatments. The neoplastic tissue was covered by blood, fibrin, and bacterial colonization. The patient received palliative care in a wound healing clinic twice monthly for 1 year, and daily dressing changes were performed at home. Binding bacteria dressings, silver dressings, and absorbent dressings were used to control exudate and infection. Alginate was used to manage bleeding, and charcoal dressings were used to manage odor. The dressings were covered with gauze and bandage. Additionally, swabs were performed when signs of infection were present and targeted systemic antibiotic treatment administered. Conclusions. Squamous cell carcinoma rarely presents with a devastating and rapid evolution. In this case, the local approach was based on the TIME (tissue, inflammation/infection, moisture imbalance, epithelial edge advancement) concept, with special attention paid to the most significant features of neoplastic wounds (eg, pain, exudate, bleeding, odor). Despite the patient’s serious conditions, he survived for a relatively long time.

Introduction. Due to venous insufficiency, a vascular ulcer frequently occurs with the progression of stasis dermatitis. Achromic melanoma, a rare form of pigmentless melanoma frequently located on the sole of the foot, is often and easily confused with a typical wound. Diagnosis of ulcerated achromic melanoma is thus often delayed and associated with a poor prognosis. Case Report. The authors report a very rare case of malignant melanoma in a 70-year-old female with stasis dermatitis. The painless ulcer was present for 1 year before the first visit. Upon clinical examination, a 2-cm diameter hypergranulating ulcer with irregular and pigmented borders was present. Dermoscopy revealed the presence of red globules, a gray-to-blue veil, irregular vessels, and the remains of a pigmented ridge pattern. Histological analysis showed infiltration of atypical melanocytes in the dermis, 2 mitoses, and ulceration. Diagnosis of melanoma was confirmed by positive MART-1 immunochemistry. After removal of the melanoma, the area was covered with an autologous skin graft excised from the inner thigh. In accordance with the guidelines, sentinel lymph node biopsy was performed, and the result was negative for lymph node involvement. A comprehensive clinical dermoscopic evaluation led to the correct diagnosis. Conclusions. The current case highlights the importance of evaluating a chronic, atypical, nonhealing ulcer clinically and dermoscopically as well as through a biopsy procedure.

BACKGROUND High-frequency ultrasound (HFUS) is a non-invasive method that detects superficial skin features. Ultra-high frequencies (50-100 MHz) can reveal epidermis and dermis structures. OBJECTIVES In this study, we describe the psoriatic plaque using a new device equipped with a 70 MHz probe (VEVO® MD, Fujifilm, VisualSonics) and we assess the lesion before and after ixekizumab. METHODS We examined the superficial hyperechoic band, the subepidermal hypoechoic band (SLEB), and the vascularization of the plaque in ten patients affected by plaque psoriasis. RESULTS The average superficial hyperechoic band thickness was 0.2157 mm before treatment, 0.1611 mm after 15 days, and 0.1354 mm (P

This study investigated the peripheral blood lymphocytes (PBL) response to a dose of γ-rays in patients treated with radioiodine (I-131) for hyperthyroidism vs. healthy controls, to gain information about the individual lymphocytes’ radio-sensitivity. Blood samples were taken from 18 patients and 10 healthy donors. Phosphorylated histone variant H2AX (γ-H2AX) and micronuclei (MN) induction were used to determine the change in PBL radio-sensitivity and the correlations between the two types of damage. The two assays showed large inter-individual variability in PBL background damage and in radio-sensitivity (patients vs. healthy donors). In particular, they showed an increased radio-sensitivity in 36% and 33% of patients, decrease in 36% and 44%, respectively. There was a scarce correlation between the two assays and no dependence on age or gender. A significant association was found between high radio-sensitivity conditions and induced hypothyroidism. PBL radio-sensitivity in the patient group was not significantly affected by treatment with I-131, whereas there were significant changes inter-individually. The association found between clinical response and PBL radio-sensitivity suggests that the latter could be used in view of the development of personalized treatments.

Background: Psoriatic arthritis (PsA) is an inflammatory condition which can affect up to 41% of psoriatic patients [1]. In 40-60% of patients, PsA can determine cartilage destruction and joint deformities, hereby heavily impacting physical function and quality of life, even increasing the risk of death compared to the general population[1]. PsA manifestations usually develop after psoriasis onset, therefore dermatologists play a crucial role in the detection of early signs of arthritis. In our study, we aimed to identify simply detectable clinical and ecographic signs of early PsA and to assess their reliability. Materials and methods: We assessed the opinion of a group of expert dermatologists, who were asked to express their opinion on the level of association between the selected anamnestic, clinical or instrumental signs and the onset of psoriatic arthritis by giving a score to each item. Results: Psoriatic onycopathy, signs of dactylitis and ultrasonographic alterations of selected joints were, respectively, the dermatologic, rheumatologic and imaging signs which had the strongest significance in the opinion of the experts. Conclusions: These signs should be carefully looked for during dermatological examinations in order to detect early PsA.

Psoriasis is one of the commonest inflammatory skin diseases determining a very high impact on patients' quality of life and daily activities and relationships. Several biologic therapies have been approved through the years for the treatment of moderate-to-severe plaque psoriasis, and efficacy and safety profile have been analyzed in clinical trials. Ixekizumab is an immunoglobulin G subclass 4 monoclonal antibody that selectively targets and binds IL-17A with high specificity and affinity. Inhibiting IL-17A activity, ixekizumab reduces and turns down levels of inflammation, resulting in the clinical improvement of the disease. Long-term efficacy and safety profile of ixekizumab have been investigated and reported in the UNCOVER trials, but in literature there are only few studies based on real life experience. We present the efficacy and safety profile of ixekizumab in a cohort of 779 patients affected by moderate-to-severe plaque psoriasis and treated with ixekizumab in 11 Italian dermatology hospitals, with a follow-up of care until 192 weeks.

MolecuLight i:X is a autofluorescence, portable device that allows an assessment of wound area, perimeter, width and length and an evaluation in real time of wound surface bacteria (>104 CFU/g). Primary objective of our study was to evaluate the reduction of bacterial load associated to 3 different therapeutic approaches: dressings and multicomponent bandages (Group1), sharp debridement, dressings and multicomponent bandages (Group 2), and 10 patients treated with zinc oxide bandage (Group 3). Secondary objective was NRS pain scale, Wound Bed Score (WBS) and Quality of Life (QoL) assessment. Despite the improvement of bacterial load, WBS, Qol and NRS was evident in all 3 groups, the analysis of our results demonstrates that the application of zinc oxide bandage, directly in contact with the wound bed and/or the perilesional skin, resulted in a higher improvement and a significant reduction of WBS and bacterial load. Fluorescence imaging can help the specialist in a more targeted assessment and management of infection. Sharp debridement and antiseptic dressings are classically used to reduced bacteria burden. Zinc oxide directly on the wound is an interesting cost-effective option to control different types of bacteria.

Introduction: Treat-to-target strategies are used in several chronic diseases to improve outcomes. Treatment goals have also been suggested for psoriasis, but there is currently no consensus on targets, and guidance is needed to implement this strategy in clinical practice. The project ‘Treat to Target Italia’ was launched by a scientific board (SB) of 10 psoriasis experts to generate expert consensus recommendations. Methods: On the basis of the published literature, their clinical experience, and the results of a survey among Italian dermatologists, the SB identified four relevant topics: (1) clinical remission; (2) quality of life; (3) abrogation of systemic inflammation; (4) safety. They drafted 20 statements addressing these four topics and submitted them to a panel of 28 dermatologists, in a Delphi process, to achieve consensus (greater than 80% agreement). Results: Consensus was reached on all statements. Treatment goals defining clinical remission should include a 90% improvement from baseline in the Psoriasis Area and Severity Index (PASI90 response) or an absolute PASI score of less than or equal to 3. Patient’s quality of life and satisfaction are important targets. If PASI targets are achieved, there should be no or very low impact of psoriasis on quality of life [Dermatology Life Quality Index (DLQI) score less than or equal to 3]. If PASI or DLQI goals are not achieved within 3–4months, treatment should be changed. Abrogation of systemic inflammation may be crucial for preventing or delaying inflammatory comorbidities. Safety is an equally important target as efficacy. Conclusion: These 20 consensus statements define the parameters of a treat-to-target strategy for psoriasis in Italy. It is hoped that use of these in the management of patients with psoriasis will improve treatment outcomes and patient health-related quality of life.

Objectives: Ultra-high frequency ultrasonography (UHFUS) is a recently introduced diagnostic technique which finds several applications in diverse clinical fields. The range of frequencies between 30 and 100 MHz allows for high spatial resolution imaging of superficial structures, making this technique suitable for the imaging of skin, blood vessels, musculoskeletal anatomy, oral mucosa, and small parts. However, the current clinical applications of UHFUS have never been analyzed in a consistent multidisciplinary manner. The aim of this study is to revise and discuss the current applications of UHFUS in different aspects of research and clinical practice, as well as to provide some examples of the current work-in-progress carried out in our center. Materials and Methods: A literature search was performed in order to retrieve articles reporting the applications of UHFUS both in research and in clinical settings. Inclusion criteria were the use of frequencies above 30 MHz and study design conducted in vivo on human subjects. Results: In total 66 articles were retrieved. The majority of the articles focused on dermatological and vascular applications, although musculoskeletal and intraoral applications are emerging fields of use. We also describe our experience in the use of UHFUS as a valuable diagnostic support in the fields of dermatology, rheumatology, oral medicine, and musculoskeletal anatomy. Conclusion: Ultra-high frequency ultrasonography application involves an increasing number of medical fields. The high spatial resolution and the superb image quality achievable allow to foresee a wider use of this novel technique, which has the potential to bring innovation in diagnostic imaging.

Aim To evaluate the distinct contribution of obesity and diabetes (DM) to the skin modification in metabolic diseases. Methods We analysed all patients admitted for bariatric surgery in our hospital with BMI between 38 and 47 kg/m2, with (Group 1) or without (Group 2) DM and compared them with a group of nonobese diabetic patients (Group 3) and healthy volunteers (Group 4). The following features were evaluated: hardness, temperature, hydration and thickness alongside with anthropometric measures of foot and leg. Results For the general characteristics, patients differed in age and body mass index. As predictable all circumferences (dorsal foot, sovramalleolar and under the knee) were significantly higher in obese with no differences depending on DM (all parameters: p

In Italy, few epidemiologic studies have been conducted by tracing melanoma reports directly in the electronic registers of the operating units of pathologic anatomy. The Cancer Registers of the Italian regions receive only partial and incomplete data on the diagnoses of melanoma, for this reason, the incidences are usually underestimated. Our work offers a precise picture of the epidemiologic situation of melanoma in a homogenous sample of patients residing in a geographic area traditionally considered to have a high incidence of melanoma.

Immune dysregulation, in combination with genetic and epigenetic alterations, induces an excessive proliferation of uncontrolled melanoma cells followed by dissemination of the tumor cells to distant sites, invading organs and creating metastasis. Although immunotherapy, checkpoint inhibitors and molecular targeted therapies have been developed as treatment options for advanced melanoma, there are specific mechanisms by which cancer cells can escape treatment. One of the main factors associated with reduced response to therapy is the ability of residual tumor cells to persist in a dormant state, without proliferation. This comprehensive review aimed at understanding the genetic basis of dormancy/awakening phenomenon in metastatic melanoma will help identify the possible therapeutical strategies that might eliminate melanoma circulating tumor cells (CTCs) or keep them in the dormant state forever, thereby repressing tumor relapse and metastatic spread.

Psoriasis is a skin disorder characterized by chronic inflammation driven by different immunologic pathways, among which the IL-23/Th17 axis plays a pivotal role. For this reason, the use of IL23p19 inhibitors in psoriasis treatment has been evaluated over the years. Guselkumab, a totally human IgG1 lambda monoclonal antibody, that selectively blocks the p 19 subunit of IL- 23 has demonstrated high efficacy and safety throughout several, randomized, double-blind phase III trials (VOYAGE 1 and 2, NAVIGATE and ECLIPSE). We designed a single-center retrospective cohort study in a population consisting of 46 patients followed from December 2018 to April 2021. After a diagnosis of moderate to severe psoriasis, all the patients were considered suitable to receive treatment with Guselkumab. In our population, among those who achieved clinical improvement in terms of Psoriasis Area Severity Index (PASI), PASI 75, 90, and 100 were achieved on average on weeks 14, 19, 21 respectively. We then analyzed a subgroup of our population, consisting of 35 patients, who had an identical follow-up time of 28 weeks, thus observing the trend in mean PASI at subsequent assessments and the number of patients who had reached PASI 75, PASI 90, and PASI 100 at week 4 (10; 3; 1), week 12 (12; 13; 11), week 20 (7; 6; 2), and week 28 (1; 4; 6), respectively. The results obtained are in line with those obtained from previous studies, thus confirming that Guselkumab is an excellent choice in terms of security, long-term efficacy, and overall tolerance.

Background: To assess skin involvement in a cohort of patients with systemic sclerosis (SSc) by comparing results obtained from modified Rodnan skin score (mRSS), durometry and ultra-high frequency ultrasound (UHFUS). Methods: SSc patients were enrolled along with healthy controls (HC), assessing disease-specific characteristics. Five regions of interest were investigated in the non-dominant upper limb. Each patient underwent a rheumatological evaluation of the mRSS, dermatological measurement with a durometer, and radiological UHFUS assessment with a 70 MHz probe calculating the mean grayscale value (MGV). Results: Forty-seven SSc patients (87.2% female, mean age 56.4 years) and 15 HC comparable for age and sex were enrolled. Durometry showed a positive correlation with mRSS in most regions of interest (p = 0.025, ρ = 0.34 in mean). When performing UHFUS, SSc patients had a significantly thicker epidermal layer (p < 0.001) and lower epidermal MGV (p = 0.01) than HC in almost all the different regions of interest. Lower values of dermal MGV were found at the distal and intermediate phalanx (p < 0.01). No relationships were found between UHFUS results either with mRSS or durometry. Conclusions: UHFUS is an emergent tool for skin assessment in SSc, showing significant alterations concerning skin thickness and echogenicity when compared with HC. The lack of correlations between UHFUS and both mRSS and durometry suggests that these are not equivalent techniques but may represent complementary methods for a full non-invasive skin evaluation in SSc.

Cellutome™ is a minimally invasive, automated system for harvesting fractional epidermal micrografts. This therapy is indicated for granulating, small size, poor exuding acute wounds. We enrolled 15 patients with 9 venous leg ulcers and 6 atypical ulcers. The micrografts were applied with a nonadherent dressing and covered with a polyurethane foam and multilayer bandage. We scheduled 3 weekly visits for the change of the secondary dressings and multilayer bandage and clinical assessment (Wound Bed Score [WBS], pain assessment, and healing rate). The lesions were measured with the Silhouette Star™ system, a software that allows measurement of perimeter and area from a digital image. The only symptom during the procedure was a sensation of warmth. The donor area healed in 2 weeks in all patients ( n = 15). We reported an area reduction of 24.30% in typical ulcers and 38.82% in atypical ulcers after 3 weeks. The average WBS improved in all ulcers from 13.06 to 14.93. The average healing rate was 0.19 mm/day both in typical and atypical ulcers. Consequently, in our small case series fractionated epidermal graft treatment significantly promoted the healing rate in all chronic ulcers regardless of etiology. Future studies with larger case series will be needed.

Introduction. Achilles tendon rupture is a common injury requiring surgical repair. Re-ruptures, infections, delayed wound healing, and hematomas have been reported postoperatively. Objective. This case series described the use of ultraportable negative pressure wound therapy (NPWT) and compression bandaging following postoperative dehiscence of Achilles tendon repair. Materials and Methods. Retrospective records were reviewed to identify patients who underwent wound management for Achilles tendon dehiscence between January 2014 and January 2018. Patient demographics, wound size at first and last visit, number of visits, and previous treatment data were extracted. Wound management included wound irrigation, surgical debridement, and application of silver dressings, as needed. Therapy was transitioned to ultraportable NPWT with twice-weekly dressing changes. When possible, patients with an ankle-brachial index greater than 0.8 received multilayer, multicomponent compression. Treatment response was evaluated using a wound imaging system at 2-week to 4-week intervals for a total of 24 weeks. Results. Nine male patients with a mean age of 69.7 years presented for care. One patient sustained injury during sports activities, and the other 8 patients sustained injuries resulting from household accidents. Six patients achieved complete wound closure. Three patients achieved a mean 90% wound closure. No adverse effects were observed during treatment with NPWT and compression therapy. Conclusions. In the current study, ultraportable NPWT and compression bandaging were found to be effective in the management of wounds with critical local vascularity. Larger, randomized controlled studies are necessary to fully assess the potential clinical benefit of NPWT and compression therapy in the management of postoperative wounds of the Achilles tendon.

Contains fulltext : 249929.pdf (Publisher’s version ) (Closed access) Malignant melanoma (MM) is one of the most dangerous skin cancers. The aim of this study was to present a potential new method for the differential diagnosis of MM from melanocytic naevi (MN). We examined 20 MM and 19 MN with a new ultra-high-frequency ultrasound (UHFUS) equipped with a 70 MHz linear probe. Ultrasonographic images were processed for calculating 8 morphological parameters (area, perimeter, circularity, area ratio, standard deviation of normalized radial range, roughness index, overlap ratio and normalized residual mean square value) and 122 texture parameters. Colour Doppler images were used to evaluate the vascularization. Features reduction was implemented by means of principal component analysis (PCA), and 23 classification algorithms were tested on the reduced features using histological response as ground-truth. Best results were obtained using only the first component of the PCA and the weighted k-nearest neighbour classifier; this combination led to an accuracy of 76.9%, area under the ROC curve of 83%, sensitivity of 84% and specificity of 70%. The histological analysis still remains the gold-standard, but the UHFUS images processing using a machine learning approach could represent a new non-invasive approach.

The aims of our study were to evaluate with ultra-high-frequency ultrasound (UHFUS) the ultrasound features of congenital melanocytic nevi (CMNs) and malignant melanomas (MMs) arising in CMNs and the correlation between ultrasonographic thickness and histological thickness in MMs. We evaluated 10 patients with small-medium CMNs and 10 patients with MMs arising in small-medium CMNs. We collected patient's data, clinical and dermoscopic features. The UHFUS was performed using a 70 MHz frequency probe to study the ecostructure, shape and vascularization. Breslow thickness was compared with ultrasonographic thickness. In the MMs group the following dermoscopic features were described: hyperpigmentation (n = 9), regression area (n = 6), whitish-blue veil (n = 5), thickened network (n = 5), irregular globules (n = 3), inverse network (n = 2) and striae (n = 1). Hyperpigmentation (n = n = 9), thickened network (n = 7), irregular globules (n = 5), regression area (n = 5), striae (n = 1) and whitish-blue veil (n = 1) were found in the CMNs group. The multicomponent pattern was present in both MMs (n = 4) and in CMNs (n = 5). Moreover, the parameters indicative of suspected malignancy were variously combined in the two groups, without showing significant differences in the statistical analysis; with the exception of the blue veil that correlated with the diagnosis of MM. Ultrasonoghaphic vascularization was an ever-present parameter in MMs (100%), with high intensity of intratumoral signal, as opposed to CMNs. We also found a statistically significant correlation between ultrasound thickness and Breslow thickness. In the future, this technique could implement the diagnostic preoperative phase of MMs arising in CMNs in combination with standard clinical-dermatoscopic evaluation.

To provide a full characterization of proper palmar digital arteries (PPDA) in systemic sclerosis (SSc) with ultra-high frequency ultrasound (UHFUS), and to investigate possible relationships between digital macroangiopathy and microangiopathy.SSc patients without active digital ulcers and healthy controls (HC) were enrolled. Each subject underwent UHFUS 70 MHz evaluation of PPDA from II to V fingers bilaterally, searching for vessel occlusion and measuring the thickness of the three arterial layers and the systolic-diastolic excursion range. Microcirculation was investigated with capillaroscopy and laser speckle contrast analysis (LASCA).Forty-six SSc patients (87% female, mean age 55.5 years) and 15 HC comparable for age and sex were enrolled. UHFUS in SSc revealed the occlusion of 124 (16.8%) PPDA, whereas in HC they were all patent. Considering a finger with at least one PPDA occluded as ultrasonographically pathological, 67.4% patients presented ≥1 pathological fingers. All three arterial layers were significantly thicker and excursion range significantly reduced in SSc than in HC (p0.001 for all). Seventy-three percent of fingers previously affected by digital ulcers, were ultrasonographically pathological. Disease duration was directly correlated to the thickness of all three arterial layers. No significant correlations emerged between capillaroscopy or LASCA findings and UHFUS features.UHFUS allows the characterization of vasculopathic involvement of PPDA in SSc, also showing subclinical vasculopathy. The lack of correlations between UHFUS and capillaroscopy or LASCA likely mirrors non-overlapping vasculopathic processes. UHFUS evaluation of PPDA emerges as complementary to microcirculation assessment for a more accurate and complete characterization of SSc vasculopathy.

Background The management of hidradenitis suppurativa (HS) flares with intralesional steroids lacks strong scientific evidence but limited data suggest that it may be useful. Objective To assess the clinical and ultrasound responses of HS flares to ultrasound-guided injections of intralesional triamcinolone (40 mg/mL) with a dilution 1:4 vs 1:2 at 30-day (t1), 60-day (t2) and 90-day (t3) follow-up. Materials and methods We recruited patients with ≤3 acute lesions, unresponsive to topical therapy. At baseline we assessed lesions clinically and by ultra-high frequency ultrasound (48 or 70MHz) and randomly performed an ultrasound-guided injection of triamcinolone. Assessments were repeated at t1, t2 and t3 follow-up, re-injecting the lesion in the case of no or partial response. Results We treated 49 lesions: 38.8% showed improvements at t1; 46.9% at t2; 6% at t3; and 8.3% showed no clinical and ultrasound improvements. Long-term follow-up data confirmed a statistically significant reduction in VAS-pain, Dermatology Life Quality Index (DLQI), and HS-Physician Global Assessment (HS-PGA), as well as edema and vascular signals. No adverse effects were reported. Conclusions Our study suggests that ultrasound-injections with a 1:2 dilution are beneficial for HS flares that do not respond to topical treatment and should be included in the therapeutic algorithm. The preliminary results of this study were presented during the European Hidradenitis Suppurativa Foundation 2020 meeting in Athens and the abstract will be published in the supplements of Experimental Dermatology.

Background Hidradenitis suppurativa is a chronic inflammatory skin disease. An ultrasound staging (SOS-HS) using frequencies from 7 to 18 MHz has been proposed to evaluate the severity of the disease. Materials and methods We retrospectively evaluated the most significant lesions in 50 patients with hidradenitis suppurativa (32 females and 18 males, aged from 12 to 68 years old), who had undergone high-frequency ultrasound (HFUS) (18-22 MHz) and ultra-high frequency ultrasound (UHFUS) (48 and 70 MHz). A MyLab™ Touch system (Esaote) equipped with a 18-22 MHz linear probe was used for the HFUS, and a Vevo® MD (VisualSonics) was used for the UHFUS, equipped with two linear probes (70 and 48 MHz). Results A total of 116 lesions were observed, of which 66 were fluid collections, 32 were tunnels, 6 pseudocysts, 5 bridge scars, 5 tombstone comedones, and 2 granulation tissues. Structures that had already been described with HFUS were then observed with UHFUS but with a better definition. In addition, structures that had not been detected by HFUS were also observed with UHFUS such as drop-shaped hair follicles, micro-tunnels, and microcysts. Conclusion Ultra-high frequency ultrasound provides a better understanding of hidradenitis suppurativa. Patients can be monitored more effectively thereby preventing the most severe changes.

Atypical ulcers show atypical clinical features, histology, localization, and resistance to standard therapies. The persistence of a chronic ulcer despite treatment with standard therapies requires a more specific diagnostic investigation. Diagnosis involves obtaining the history and performing clinical examination and additional tests. A skin biopsy is frequently used to confirm unclear diagnosis. In difficult cases, microbiological and immunohistochemical examinations, laboratory blood tests, or instrumental tests should be evaluated. The treatment of atypical wounds is characterized by local systemic therapy and pain control. Our results highlight the need for early diagnosis, and standardized and targeted management by a multidisciplinary wound healing center.

Objective: The recently completed EUREKA study confirmed the efficacy and safety profile of fluorescent light energy (FLE) in treating hard-to-heal wounds. To supplement the EUREKA prospective, observational, uncontrolled trial results, researchers selected one of the EUREKA clinical centres to conduct a retrospective analysis of matching wound care data for 46 venous leg ulcers (VLU) patients who had received standard wound care over a five-year period, compared with 10 EUREKA VLU subjects. Method: The study centre selected 46 patients with VLUs based on the matching criteria (wound age and size, patient's age and gender). They compared the healing rates of these matching VLUs with 10 VLU patients treated at the same centre during the EUREKA study. Results: The EUREKA patients had larger and significantly older wounds (pConclusion: These findings show that the system based on FLE was well-tolerated and efficacious, with better clinical outcome results compared with the wounds analysed in this retrospective matching study and treated with standard of care alone.

BACKGROUND A rationalized model of clinical and therapeutic management of hidradenitis suppurativa (HS) should place the patients at the heart of the process, facilitating their access to diagnostic tests and treatments, providing the appropriate care for each grade of disease severity and optimizing the use of healthcare resources, both in economic and human terms. MATERIAL AND METHODS This paper reports the results of a Consensus of the Tuscany HS working group for a rationalized model of diagnosis and management of HS. RESULTS The diagnostic and therapeutic protocols, the available technological equipments and the management models, are presented in the light of today's scientific evidence. CONCLUSION The goal of the Consensus is to bring the issue of HS management to the attention of the Tuscan regional government, in order to create unanimously accepted diagnostic and therapeutic protocols.

The omentum is a large peritoneal fold. Its main function is to protect abdominal organs, exerting a defensive action against infective agents. The tissue promotes repair after several types of injury. An extensive vascularisation is the key characteristic of this tissue and the omentum has the highest level of production and content of vascular endothelial growth factor (VEGF). A component of omentum is the lipid compound, which carries out important activities for the organism. Omentum is rich in neutral glycerides, phospholipids, glycolipids and gangliosides. Dermatological products containing purified omental lipids are commercially available and topical omental extracts have been useful in the softening, moisturising and smoothing of skin. Animal-derived omental lipids could be use in topical products with different textures (creams, fluids, emulsions and cleansers) and at different concentrations (10–25%) for the treatment of fragile skin or skin conditions causing risk of ulcer formation. This review summarises the pharmacological rationale of purified omental lipids in topical formulations for use in fragile skin conditions, the clinical efficacy data available in the scientific literature and the potential future perspectives. Efficacy of topical purified omental lipids have been demonstrated in numerous clinical controlled trials involving a total of 320 subjects. These studies demonstrated that this product helps prevent the formation of pressure ulcers (PU) in hospitalised high-risk subjects, improves wound healing process, normalises skin hydration in diabetic subjects with moderate-severe skin xerosis and improve the clinical evolution of diabetic foot. Therefore, purified omental lipid could be an effective tool for the management of fragile skin and the skin at high risk of PU formation.

Atopic dermatitis (AD) is a chronically relapsing skin disease. Although a definitive cure is not available, appropriate treatment can control the disease. The advent of biologic drugs has led to the need for a clear definition of the disease severity and treatment response. A standardized list of outcomes that defines clinician-reported disease severity and patients' reported severity are therefore essential. Solid criteria to define the response to treatment and treatment failure are lacking to date.This systematic review defines treatment goals in terms of clinician-reported disease severity and patient-reported outcomes, referring to the published moderate-to-severe AD clinical trials. The application of these goals in daily clinical practice will ensure a better selection of available treatment options, thus increasing patient quality of care.A systematic literature search was performed to identify the treatments goals of randomized controlled clinical trials (RCTs) on moderate-to-severe adult AD published between January 2000 and October 2020.In total, 14 studies met the eligibility criteria. The most widely used tools in terms of clinician-reported disease severity were the Scoring of Atopic Dermatitis (SCORAD) followed by the Eczema Area Severity Score (EASI) and Investigator Global Assessment (IGA). For disease severity scales as efficacy outcome in RCTs, the greatest standardization and reproducibility was for improvement of at least 50% in EASI score and IGA score reduction of ≥2 grades from baseline. The most widely used tools from the patients' perspective were the Dermatology Life Quality Index (DLQI), Numeric Rate Scale (NRS)-itch and Patient Oriented Eczema Measure Score (POEM). In terms of patients' reported efficacy outcomes in RCTs, a numerical DLQI, NRS-itch and POEM score improvement of at least 4 points from baseline was reported.This systematic review highlights the need for collaboration between experts in order to define and optimize treatment outcomes. Despite considerable progress in harmonizing outcome measures, promoted by the foundation of the Harmonizing Outcome Measures for Eczema (HOME) initiative in 2008, our results demonstrate that this endpoint is still an unmet need. Based on the literature data we propose a minimum treatment goal algorithm for use in daily clinical practice aimed at stimulating a discussion on how the care of AD patients could be further improved.

A nationwide survey was conducted in adult patients with psoriasis (PsO) across Italy to obtain their real-world perspective of the impact of PsO on their wellbeing. Patients completed a 26-question survey (based on the patient benefit index; PBI, The Dermatology Life Quality Index; DLQI and the World Health Organization-five; WHO-5 wellbeing index) and workshop discussion sessions were undertaken by dermatologists to interpret results from the survey. 392 patients with PsO completed the survey. Analysis of results was restricted to patients who had moderate-to-severe plaque psoriasis (assessed by patients; n = 252; 64.3%). Dermatologists (n = 32) completed one question from the survey related to wellbeing and rated social, physical and mental domains as contributing to a similar extent, with comparable scores also observed by patients. For treatment, biologics yielded higher scores on average, whereas little difference was observed between topical and conventional systemic treatments. Only 23.8% of patients felt that their dermatologist was taking into consideration their wellbeing and 32.6% of the patients considered their therapy as inadequate in improving signs and symptoms of the disease. This survey identified key factors contributing to barriers impacting on patient wellbeing. Simple, but comprehensive questionnaires can provide important insight to patients’ needs that may significantly increase clinician awareness during visits leading to tailored treatment.

Healing rate is the most accurate method to predict healing; however, there are no data in atypical ulcers. We retrospectively analyzed clinical features, associated comorbidities, and therapies of 159 patients with atypical ulcers. In a subgroup of 59 patients, we analyzed the areas, perimeters, and the healing rate (mm/d) as prognostic indicators of wound healing. Atypical ulcers were more frequent among women (n = 98) with an average age of 76 years. Confirmed by biopsy, the etiologies were as follows: inflammatory diseases (38%), neoplastic ulcers (29%), vasculitis (21%), drug-induced ulcers (7%), and infectious ulcers (4%). Systemic therapies were applied based on the different etiologies. Wound bed preparation principles guided the local treatment. The average reduction of the area during the observation interval was 36%, while the average reduction in the perimeter was 41%. Overall, 51 ulcers showed a reduction in wound size and 8 ulcers showed an increase. Neoplastic ulcers were the group with the fastest healing rate, with an average speed of 0.24 mm/d. The slowest healing occurred in the inflammatory group with an average healing rate of 0.032 mm/d. The initial area and perimeters influenced wound healing; however, ulcer etiology and comorbidities significantly altered the healing rate.
