RESUMO
BACKGROUND: Preliminary data support the possible use of ultraviolet-induced fluorescence (UVF) dermoscopy in general dermatology, yet no accuracy analysis has been performed so far. OBJECTIVE: To evaluate diagnostic accuracy of UVF dermoscopy in clinically similar non-neoplastic conditions as compared to polarized light-based dermoscopy. METHODS: Patients with dermatoses potentially showing UV-induced findings were considered; cases were grouped according to clinical patterns and controls were also included. Standardized evaluation of dermoscopic pictures of the target lesion along with comparative and accuracy analysis were performed for polarized and UVF dermoscopic findings. RESULTS: A total of 208 patients were included [31 foot intertrigo (7 due to Pseudomonas, 13 due to Corynebacterium and 11 due to dermatophytes); 57 intertrigo of major creases (18 inverse psoriasis, 13 erythrasma, 15 tinea infections and 11 candidiasis); 16 acne (papulopustular) and 13 Malassezia folliculitis; 46 papulosquamous dermatoses (14 guttate psoriasis, 11 lichen planus, 12 pityriasis rosea and 9 pityriasis lichenoide chronica); and 45 hypopigmented macular dermatoses of the trunk (9 progressive macular hypomelanosis, 9 idiopatic guttate hypomelanosis, 13 vitiligo and 14 achromic pityriasis versicolor)]. Significant (p < 0.01) UVF was seen in several conditions: green in Pseudomonas foot intertrigo; red in Corynebacterium foot intertrigo, inverse and guttate psoriasis (arranged around dermal papillae in the former), progressive macular hypomelanosis (folliculocentric distribution) and erythrasma (showing polygonal or structureless appearance); blue fluorescent concretions along hair shaft in erythrasma; light green in achromic pityriasis versicolor and tinea of major creases; and blue follicular in Malassezia folliculitis. Additionally, both acne and achromic pityriasis versicolor were also associated with interruption of uniform follicular red fluorescence. Notably, polarized and UVF dermoscopy were related to the most accurate feature in nine and eight analysed dermatoses, respectively. CONCLUSION: UVF dermoscopy improves recognition of non-neoplastic dermatoses, yet it should be considered complimentary to polarized light-based dermoscopy to increase diagnostic performance.
RESUMO
PURPOSE OF REVIEW: Skin rashes seen during COVID-19 usually feature maculopapular or vesicular morphology, thus mimicking cutaneous eruptions occurring in other common infectious dermatoses, such as mononucleosis, chickenpox, sixth disease and measles, with possible diagnostic mistakes. In this review article, we sought to provide a practical overview about clinical appearance of skin rashes related to SARS-CoV-2 infection. RECENT FINDINGS: The study summarizes literature evidence on clinical patterns of COVID-19-associated maculopapular or vesicular rash, with a particular emphasis on the principal points of differentiation with possible mimickers. SUMMARY: Several differences do exist between rashes due to SARS-CoV-2 infection and other viral eruptions, mainly including lesions morphology, spreading pattern, symptoms and mucosal involvement. The increase of awareness of such features among clinicians may help promptly recognize COVID-19-related exanthemas in order to take proper action to manage the infection.

BACKGROUND: Limited data on dermatoscopy of nodular/plaque-type T-/B-cell primary cutaneous lymphomas (PCLs) is available. OBJECTIVE: To describe dermatoscopic features of nodular/plaque-type PCLs, comparing them with those of clinical mimickers (pseudolymphomas, tumors, and inflammatory lesions) and investigating possible differences according to histologic subtypes. METHODS: Participants were invited to join this retrospective, multicenter case-control study by submitting histologically/immunohistochemically confirmed instances of nodular/plaque-type PCLs and controls. Standardized assessments of the dermatoscopic images and comparative analyses were performed. RESULTS: A total of 261 lesions were included (121 PCLs and 140 controls). Orange structureless areas were the strongest PCL dermatoscopic predictor on multivariate analysis compared with tumors and noninfiltrative inflammatory dermatoses. On the other hand, a positive association was found between PCLs and either unfocused linear vessels with branches or focal white structureless areas compared with infiltrative inflammatory dermatoses, whereas white lines were predictive of PCLs over pseudolymphomas. Differences in the vascular pattern were also seen between B- and T-cell PCLs and among B-cell PCL subtypes. LIMITATIONS: Retrospective design and the lack of a dermatoscopic-pathologic correlation analysis. CONCLUSION: Nodular/plaque-type PCLs display dermatoscopic clues, which may partially vary according to histologic subtype and whose diagnostic relevance depends on the considered clinical differential diagnoses.

OBJECTIVES: To evaluate the prevalence of articular/extra-articular inflammatory lesions and structural damage on ultrasonography in patients suffering from psoriasis as well as to assess possible correlations between ultrasonographic elementary lesions and clinical features. METHODS: Psoriatic patients without musculoskeletal symptoms and healthy controls (HCs) were recruited. All patients received a blinded extended ultrasonographic examination of 42 joints, 12 entheses and 32 tendons. Active synovitis was defined by the presence of a grade ≥2 for grey scale (GS) and ≥1 for power Doppler (PD), while active enthesitis corresponded to entheseal hypoecogenicity in GS and entheseal PD signal (<2 mm from bone insertion). RESULTS: Forty psoriatic patients and 20 HCs were included. A total of 2516 joints and 712 entheses were scanned. Active synovitis was found in 11/40 (27.5%) psoriatic patients and 0/20 HCs (p=0.01). Articular synovitis (GS≥2) was more frequent in psoriasis than in HCs [34/40 (85.0%) and 11/20 (55.0%) respectively; p=0.024). Active enthesitis was found only in psoriatic patients, with a prevalence of 20.0% (8/40) (p=0.04). No significant difference in the prevalence of tenosynovitis or paratenonitis was observed between psoriatic patients and HCs. In psoriasis cohort, age was correlated with the presence of active synovitis (p=0.03), while male sex and a higher PASI score were independently correlated with the presence of active enthesitis (p=0.05 and p=0.034, respectively). CONCLUSIONS: Active enthesitis and synovitis could be useful to identify subclinical psoriatic arthritis. This might represent a relevant clinical step to better stratify patients with psoriasis.

BACKGROUND: Dermoscopy of morphea and cutaneous lichen sclerosus (CLS) has been described by various studies, with none of them considering variability according to clinical phases and investigating dermoscopic-histological correlations. OBJECTIVE: To evaluate dermoscopic features in general and according to clinical stage, identify possible distinctive dermoscopic clues, and assess dermoscopy accuracy in detecting subclinical alterations in morphea and CLS. METHODS: A representative dermoscopic image of target lesions was evaluated for the presence of specific features, correlating them with clinical subtype (inflammatory, inflammatory-sclerotic, sclerotic, or sclerotic-atrophic). In case of clinical-dermoscopic discordance (inflammatory, sclerotic, and atrophic findings in noninflammatory, nonsclerotic, and nonatrophic lesions, respectively), dermoscopic-pathological correspondence was assessed. RESULTS: A total of 86 lesions (51 morphea/35 CLS) were analyzed, with most of them displaying an inflammatory-sclerotic or sclerotic clinical pattern. The most common dermoscopic findings of morphea were "fibrotic beams," while CLS was mainly characterized by bright white/white-yellowish patches and yellowish-white keratotic follicular plugs; all these structures displayed complete specificity for the correspondent dermatosis. Additionally, pigmentary structures were significantly more frequent in morphea and white scaling and hemorrhagic spots in CLS. Only few dermoscopic features reached a statistical significance for a specific clinical stage. Regarding the clinical-dermoscopic discordance rate, it was significantly more common in morphea than CLS; in all cases there was a correspondence between dermoscopic and pathological findings. CONCLUSION: Dermoscopy of morphea and CLS reveals distinctive dermoscopic clues which are often unrelated to clinical stage but show a constant histological correspondence, thus emphasizing its usefulness in diagnosis and therapeutic management of these conditions.

BACKGROUND: Dermoscopy of granuloma annulare has been investigated by several studies, but none of them took into account the variability of dermoscopic findings according to clinical characteristics and/or histological subtype. OBJECTIVE: To describe the dermoscopic features of classic granuloma annulare and seek possible dermoscopic clues related to specific clinical findings/histological subpatterns. METHODS: A representative dermoscopic image of a target lesion (the most active lesion underwent histological examination) was retrospectively assessed for the presence of specific morphological findings, correlating them with clinical variables, i.e. disease duration and extension (localized or generalized) and clinical aspect (annular or non-annular) and localization (trunk or extremities) of the biopsied lesion, and with histological subtype. RESULTS: A total of 25 lesions from 25 subjects were analysed; an "interstitial" histological variant was detected in 11 cases, while a "palisading granuloma" histological pattern was found in 14 instances. The most common dermoscopic findings included blurry vessels having variable appearance (dotted, linear-irregular, and branching) over a more or less evident pinkish-reddish background, followed by whitish and/or yellowish-orange areas. Additional findings were rosettes, crystalline structures, and whitish scaling. No difference (p > 0.05) in the frequency of dermoscopic features according to clinical findings was found, while we observed a strict association (p < 0.001) between the presence of yellowish-orange structureless areas on dermoscopy and "palisading granuloma" histology. CONCLUSION: The dermoscopic aspect of granuloma annulare is independent from clinical features but varies according to histological subtype, with the detection of yellowish-orange colour being indicative of the "palisading granuloma" variant.

UNLABELLED: Pressure ulcers (PrUs) remain a concern for clinicians, patients, caregivers, and researchers. Although data on prevalence and incidence are available, as well as evidence-based prevention and management intervention, PrU healing time is underreported. OBJECTIVE: The objective of this study was to evaluate the healing time of Stage II PrUs. METHODS: Secondary analysis of data collected from a multicenter randomized clinical trial was undertaken. Patients (a) with a Stage II PrU, (b) older than 18 years, and (c) who had given informed consent were included. The endpoints of the study were complete re-epithelialization of the PrU measured with the Pressure Ulcer Scale for Healing Tool 3.0 and the healing time. A network of 46 healthcare centers located in northern Italy participated in the study. RESULTS: Two hundred seventy patients with an average age of 83.9 years (95% confidence interval [CI], 82.71-85.10) were recruited. Among 270 Stage II PrUs included, 153 lesions healed (56.7%), whereas 74 (27.4%) were still present after 10 weeks of follow-up. For 43 lesions (15.9%), the follow-up evaluation was interrupted because of patient death or transfer to units not included in the study. The PrUs healed on an average of 22.9 days (95% CI, 20.47-25.37 days), with a median of 18 days. The average healing time for PrUs of less than 3.1 cm was significantly shorter (19.2 days; 95% CI, 16.6-21.8) compared with those 3.1 cm or greater (31.0 days; 95% CI, 26.4-35.6 days) (P = .000). CONCLUSIONS: To achieve complete re-epithelialization in Stage II PrUs, it takes approximately 23 days. This is quite a long time if we consider that pressures of only 60 to 70 mm Hg for between 30 and 240 minutes are needed to cause tissue damage. On average, a small ulcer heals 12 days faster compared with those with a surface of 3.1 cm or greater.

BACKGROUND: Cutaneous melanoma is an aggressive form of skin cancer. It has become an increasingly common neoplasm in the most developed countries, especially among individuals of European origin. PATIENTS AND METHODS: Anonymous data of patients with cutaneous melanoma were collected from the diagnostic database of the University Hospital of Trieste from 1 January 1990 to 10 December 2013. Our study is based on a population which was constant over the period of observation; it was also well-defined and characterised by unrestrained sun exposure. RESULTS: The number of cutaneous melanomas increased during the period of observation with a seasonality trend and gender related differences both for anatomical sites distribution and stage of the disease. Moreover, 6% of our cohort developed multiple melanomas. CONCLUSIONS: In a well-defined population devoted to excessive sun exposure the frequencies of skin melanomas roughly doubled from 1990 to 2013 following a seasonal trend. In that population, prevention efforts according to gender specific risk behaviour, as well as follow-up programmes both for evaluation of metastatic spreading and for early diagnosis of additional skin melanomas, are crucial due to gender specific differences and to the occurrence of multiple melanomas.

BACKGROUND: Lyme Borreliosis is a multisystemic infection caused by spirochetes of Borrelia burgdorferi sensu lato complex. The features of Lyme Borreliosis may differ in the various geographical areas, primarily between the manifestations found in America and those found in Europe and Asia. OBJECTIVE: to describe the clinical features of Lyme Borreliosis in an endemic geographic area such as Friuli-Venezia Giulia in the Northeastern part of Italy. METHODS: The medical records of patients resulted seropositive for Borrelia burgdorferi have been retrospectively recorded and analyzed. RESULTS: Seven hundred and five patients met the inclusion criteria, 363 males and 342 females. Erythema migrans was the most common manifestation, detected in 437 patients. Other classical cutaneous manifestations included 58 cases of multiple erythema migrans, 7 lymphadenosis benigna cutis, and 18 acrodermatitis chronica atrophicans. The musculoskeletal system was involved in 511 patients. Four hundred and sixty patients presented a neurological involvement. Flu-like symptoms preceded or accompanied or were the only clinical feature in 119 patients. COMMENTS: The manifestations of Lyme borreliosis recorded in this study are similar to the ones of other endemic areas in Europe, even if there are some peculiar features which are different from those reported in Northern Europe and in the USA.

Background: Dermatophytosis is a prevalent superficial infection caused by filamentous fungi, primarily affecting the skin and/or its appendages. In recent years, there has been a notable increase in mycotic strains resistant to standard antifungal therapies, including Trichophyton indotineae, a dermatophyte of the Trichophyton mentagrophytes complex. This review aims to provide a comprehensive overview of the treatment options for T. indotineae, elucidating their effectiveness in managing this challenging mycotic infection. Methods: For this review, a search was conducted in the PubMed, Scopus, Web of Science, Embase, and Google Scholar databases, encompassing all published data until March 2024. English-language articles detailing therapy outcomes for patients confirmed to be affected by T. indotineae, identified through molecular analysis, were included. Results: Itraconazole was shown to be a good therapeutic choice, particularly when administered at a dosage of 200 mg/day for 1-12 weeks. Voriconazole was also demonstrated to be effective, while terbinafine exhibited a reduced response rate. Griseofulvin and fluconazole, on the other hand, were found to be ineffective. Although topical treatments were mostly ineffective when used alone, they showed promising results when used in combination with systemic therapy. Mutational status was associated with different profiles of treatment response, suggesting the need for a more tailored approach. Conclusions: When managing T. indotineae infections, it is necessary to optimize therapy to mitigate resistances and relapse. Combining in vitro antifungal susceptibility testing with mutational analysis could be a promising strategy in refining treatment selection.
RESUMO
This comprehensive review offers a detailed look at atopic dermatitis (AD) treatment in Italy, focusing primarily on the use of biologics and small molecules. In response to advancing knowledge of AD's causes and treatments, there's a global need for updated guidelines to provide physicians with a more comprehensive clinical perspective, facilitating personalized treatment strategies. Dupilumab, a groundbreaking biologic, gained approval as a significant milestone. Clinical trials demonstrated its ability to significantly reduce AD severity scores, with an impressive 37% of patients achieving clear or nearly clear skin within just 16 weeks of treatment. Real-world studies further support its efficacy across various age groups, including the elderly, with a safety profile akin to that of younger adults. Tralokinumab, a more recent approval, shows promise in clinical trials, particularly among younger populations. However, its real-world application, especially in older individuals, lacks comprehensive data. Janus Kinases inhibitors like Upadacitinib, Baricitinib, and Abrocitinib hold substantial potential for AD treatment. Nevertheless, data remains limited for patients over 75, with older adults perceived to carry a higher risk profile. Integrated safety analyses revealed individuals aged 60 and above experiencing major adverse cardiovascular events and malignancies, underscoring the need for cautious consideration. While these therapies offer promise, especially among younger patients, further research is essential to determine their safety and efficacy in various populations, including pediatric, geriatric, and those with comorbidities. Biologics and small molecules are improving AD treatment, as shown in this review.
RESUMO
INTRODUCTION: Atopic dermatitis (AD) is a chronic inflammatory skin disease that negatively impacts the quality of life and work productivity of patients. OBJECTIVES: We sought to evaluate the real-world burden of AD patients in Italy. METHODS: This sub-analysis of the MEASURE-AD multicountry study conducted between December 2019-2020 included patients diagnosed with moderate-to-severe AD eligible for or receiving systemic therapy in the previous 6 months. During a single visit, physician and patient-reported questionnaires were used. RESULTS: A total of 118 adult patients were enrolled and 57.6% (N = 68) of patients had moderate-to-severe AD at the time of enrolment according to the Eczema Area and Severity Index. Sleep disorders interfered with daily function in the previous week in 58.5% (N = 69) of patients, pruritus was severe in 50% (N = 59) and 42.4% (N = 50) reported a flare lasting >7 days in the previous 6 months. According to the Dermatology Quality of Life Index, 37.3% (N = 44) of patients reported a severe impact of AD and approximately 10% had clinical depression/anxiety. Current drug therapy was considered inadequate in controlling AD in 26.3% (N=31) of patients. Work activity impairment was 38.6±31.7% and monthly AD-related expenses were 148.6±134.6 Euros per patient. CONCLUSIONS: This real-life study documents a high burden of disease in patients with moderate-severe AD in Italy.
