RESUMO
BACKGROUND: The complexity, high prevalence, and substantial personal and socioeconomic burden collectively render atopic dermatitis (AD) a major public health concern. Using crowdsourced Internet data has the potential to provide unique insights into this concern, as demonstrated by several previous studies. However, a comprehensive comparison across European countries remains lacking. OBJECTIVES: The study aimed to investigate AD-related web searches across Europe to assess spatiotemporal variations and associations between disease-related and external factors. METHODS: AD-related web search data were extracted for 21 European countries between February 2019 and January 2023. Descriptive analysis and autocorrelation functions were performed to examine spatiotemporal patterns. Correlations (r) were used to evaluate the associations between web searches and disease-related, socioeconomic and meteorological data. RESULTS: Over 241 million AD-related web searches were identified, with search volume varying substantially among European countries (p < 0.001) and correlating with AD prevalence and disease burden (both r = 0.51, p = 0.019). Search volume increased between 2019 and 2023 in all countries and seasonally peaked in January and March. Negative correlations with median population age (r = -0.46, p = 0.039), number of general practitioners (r = -0.29, p = 0.226) and specialists (r = -0.27, p = 0.270) were observed. Moderate to strong correlations were found between search volume and cold, humid and windy weather with fewer sunshine hours, while higher online interest typically occurred 1-3 months after such weather conditions. CONCLUSION: The study highlights the great potential of online crowdsourced data analysis, for example, to investigate the impact of climate change or to identify unmet needs at a population level. Furthermore, the growing online interest in AD and the corresponding seasonal peaks emphasize the necessity of adapting treatment plans, intensifying public health campaigns, and disseminating reliable online information by governments and healthcare providers, especially during these periods.

BACKGROUND: Brodalumab, a fully human IgG2k antibody blocking the receptor of IL17, is characterized by a rapid onset of action with high skin clearance rates in clinical trials. Since setting PASI90/100 or absolute PASI ≤ 3 as treatment goals have become attainable, evaluating the effectiveness and safety profile of biologic agents, such as brodalumab, in a real-world setting is essential. OBJECTIVE: The aim of this study was to evaluate the effectiveness and safety profile of brodalumab over a period of 104 weeks in everyday practice. Clinical predictive factors of initial (week 12/16) response to treatment and long-term drug survival were also investigated. METHODS: In this monocentric, retrospective study, PASI90/100 and absolute PASI ≤ 1/3 were assessed in 91 patients with moderate-to-severe skin psoriasis under brodalumab at weeks 12/16, 24, 52 and 104 of treatment. At week 12/16, patients with an absolute PASI ≤ 3 were defined as 'initial responders' and ≤1 as 'super-responders'. Clinical parameters, such as age, gender, BMI, comorbidities and previous systemic treatment, were assessed in order to predict 'super-responders'. Drug survival and its prognostic factors were also evaluated. RESULTS: PASI90/100 has reached 81.1/66.0% in week 12/16. This response rate increased at week 104, where 87.1/80.7% had PASI90/100 and 84.9% had absolute PASI ≤ 1. The presence of >3 comorbidities, prior treatment with >2 systemic agents and obesity tended to be negative predictive factors of 'super-response'. Previous exposure to IL17 inhibitors had no impact on both PASI < 1 and PASI < 3 initial response. One- and two-year drug survival probability was 87.6% and 77.32%, respectively. 'Initial responders' and anti-IL17 drug-naïve patients had better drug survival. Drug discontinuation occurred in 24.2%, mostly due to secondary failure, and arthralgia was the most common adverse event that led to discontinuation. CONCLUSIONS: Our study confirms the high effectiveness and good safety profile of brodalumab in the real-world setting.

BACKGROUND: Recent trends in the sensitization of construction workers show a decrease in potassium dichromate and an increase in epoxy resin sensitization. OBJECTIVES: To present the trends of occupational contact allergy of construction workers in Greece from 2009 to 2018. METHODS: We retrospectively reviewed the files of patients with eczema patch tested in our Contact Dermatitis Clinic who were construction workers. RESULTS: A total of 191 construction workers initially reported contact dermatitis. Of these, 138 had occupation-relevant allergic contact dermatitis (ACD) or irritant contact dermatitis (ICD). All patients were men. After being patch tested, 98 (71.0%) were diagnosed with ACD and 40 with ICD. Median duration of occupation till onset of ACD was 2 years (interquartile range [IQR] 0.8-7). The hands were the most common location for ACD (73.5%), followed by the trunk (39.8%), the legs (38.8%), and the face (11.2%). Of the patients, 74.6% had lesions affecting multiple body sites. Potassium dichromate (67%) was the most frequent allergen, followed by thiuram mix (37.4%) and cobalt chloride (31.8%). Sensitization to epoxy resins was lower (12.1%). CONCLUSION: The sensitization pattern of Greek construction workers does not follow the trends in Central or Northern Europe, rather sharing attributes with less industrialized countries.

BACKGROUND: Oxidative hair dyes are an important source of chemical exposure and a major risk factor for the development of occupational and non-occupational allergic contact dermatitis (ACD) worldwide. OBJECTIVE: To identify the frequency of common allergens associated with occupational and non-occupational ACD to hair dyes during the last 10 years, in Greece. METHODS: We retrospectively reviewed the medical records of patients with suspected ACD to hair dyes from 2010-2019. All patients with patch-test-confirmed ACD to hair dyes were evaluated. RESULTS: Out of 501 patients with suspected ACD to hair dyes, 362 had at least one positive reaction to hair dye allergens (62.4% were customers and 37.6% were hairdressers). The mean age of customers and hairdressers was 43.8 years and 30.8 years, respectively. Of the customers, 58.9% were exposed to dyes for >10 years and 61% of hairdressers for <5 years. The most common site of ACD among customers was the scalp (85%) and among hairdressers the hands (90%). p-Phenylenediamine (PPD) was the most common contact allergen (52.2%), followed by toluene-2,5-diamine, p-aminophenol, m-aminophenol, and ammonium persulfate. CONCLUSIONS: Sensitization prevalences for PPD and cross-reacting allergens have increased in Greece during the last decade, regardless of occupational or non-occupational exposure to hair dyes.

Widespread use of oxidative hair dyes during the past decades has raised questions on the potential allergy reactions and their management, as well as prevention measures for both professionals and consumers. Allergic contact dermatitis can be elicited by various hair dye-related allergens, though the main problem remains with p-phenylenediamine and related aromatic amines. If allergy is suspected, patch testing identifies the responsible hapten. Individuals sensitized to specific permanent hair dyes substances should avoid the exposure to these chemicals, but also be aware of possible cross-sensitization to other similar compounds. Cross-reactions detected in patch-tested populations indicate that one cannot safely use alternatives, although cross-reactivity is not always clinically relevant. An open application hair dye allergy self-test is recommended by manufacturers for early detection of allergy predisposition in consumers, although the lack of standardized conditions makes the efficacy of this process doubtful. Appropriate use of hand gloves, especially nitrile, is the most efficient prevention measure for professional hand eczema. In this systematic review, we focus on cross-reactions among hair dye-related allergens and make an attempt to answer some, frequently encountered by physicians, questions, while presenting the prevalence of the hair dye-related allergens.

INTRODUCTION: Basal cell carcinoma (BCC) is the most common skin cancer worldwide and has been reported to have a rising incidence in the last years. Multiple therapeutic modalities are approved for the treatment of BCC, making it difficult for physicians to choose the most suitable option for every patient. Photodynamic therapy (PDT) using either 5-aminolevulinic acid (ALA) or methyl aminolevulinate (MAL) as photosensitizing agents is an established treatment option for low-risk BCC. OBJECTIVES: This review aims to summarize the available evidence from randomized clinical trials (RCTs) that utilize either ALA or MAL PDT and compare it with other treatment modalities. The main outcomes related to the effectiveness, adverse events, cosmetic outcomes and pain sensation, along with data from long-term follow-ups will be presented and discussed. METHODS: Thorough literature searches were conducted through the electronic databases ClinicalTrials. gov and Pubmed/MEDLINE from inception up to 28 March 2023. Only studies in English were included. All relevant data were extracted accordingly from the eligible studies. RESULTS: Eight RCTs included superficial BCC (sBCC) alone, 7 included nodular BCC (nBCC), 2 included both sBCC and nBCC and 1 included BCC of unspecified subtype. Follow-up duration ranged from 3 months to 5 years. Both ALA-PDT and MAL-PDT demonstrated acceptable efficacy, adverse events, cosmetic outcomes and pain sensation while no major differences were observed between them. PDT was less effective than surgery but with better reported cosmetic outcomes. CONCLUSIONS: PDT is a safe and efficacious treatment option for sBCC and to a lesser extent nBCC.
RESUMO
INTRODUCTION: Bimekizumab is a humanized monoclonal IgG1 antibody with a unique mechanism of action, as it inhibits both IL17A and IL17F molecules. This dual inhibition is thought to be responsible for its high efficacy in treating chronic plaque psoriasis with rapid onset of action in Randomized Controlled Trials (RCTs). Concerning safety, oral candidiasis was one of the most common drug-related adverse events, commonly mild-to-moderate in severity. Although data from RCTs supporting this efficacy and safety profile of bimekizumab is numerous, results from the real-world setting concerning short- and mid-term treatment effectiveness and safety profile are limited. MATERIALS AND METHODS: An observational, retrospective, monocentric study was conducted at the Psoriasis Outpatient Unit of "A. Sygros" Hospital for Skin and Venereal Diseases, in Athens, Greece, which included 61 adult patients with moderate-to-severe skin psoriasis, who received at least one dosage of bimekizumab. RESULTS: At week 4, 65.7% achieved PASI75, 45.7% PASI90, and 32.4% PASI100. After 16 weeks of treatment, 92.3/76.9/66.7% of the patients achieved PASI75/90/100, respectively. Increased BMI, previous treatment with another IL-17 inhibitor, or previous exposure to another biologic did not seem to influence the possibility of achieving PASI90 and PASI100 at week 16 of bimekizumab treatment in this cohort. Six (9.8%) cases of possibly drug-related AEs were reported, from which four incidences of oral candidiasis. CONCLUSION: Our results confirm that this IL17A/F inhibitor is highly effective, with a tolerability profile similar to the one expected from RCTs.

Background: Dermatoscopy has been established as an important diagnostic tool for a wide range of skin diseases. This study aims to evaluate the use of dermatoscopy in clinical practice among Greek dermatologists. Methods: A nationwide questionnaire-based survey was conducted collecting data on the frequency of dermatoscopic examinations, the types of lesions examined, training and educational resources, as well as factors influencing the choice to incorporate dermatoscopy into daily clinical routines. Results: A total of 366 Greek dermatologists participated in the survey. Most of the respondents reported the daily use of dermatoscopy in their practice. Pigmented and non-pigmented lesions, inflammatory diseases, cutaneous infectious, hair disorders, and nail lesions were the most common indications for dermatoscopy. Factors influencing the utilization of dermatoscopy included increased diagnostic accuracy, enhanced patient care, better patient communication and general compliance, and improved satisfaction among dermatologists. Conclusions: This national questionnaire-based study demonstrates that dermatoscopy has become an integral part of daily dermatological practice in Greece. The findings highlight the significance of structured training and education to promote dermoscopy's effective and routine use. Incorporating dermatoscopy into clinical practice not only improves diagnostic precision but also enhances patient care, contributing to the overall quality of dermatological services in Greece.
RESUMO
A 47-year-old Caucasian traveller from an mpox (formerly monkeypox and also best suited abbreviated MPX)-endemic country was referred for a skin rash, of recent onset, confined to the genital area. The rash consisted of erythematous umbilicated papules, vesicles and pustules with a characteristic white ring. The lesions were observed simultaneously at different stages of progression on the same anatomical site, a clinical presentation that is not encountered frequently. The patient was febrile, fatigued and had blood-tinged cough. The clinical suspicion of mpox was raised, and the initial real-time PCR identified a non-variola orthopox virus, which was confirmed at the National Reference Laboratory to belong to the West African clade.
RESUMO
BACKGROUND: Vitiligo onset during childhood is common. There are limited data regarding childhood-onset vitiligo. OBJECTIVE: We sought to provide an epidemiologic and clinical comparison between childhood- and later-onset vitiligo. METHODS: Two groups of patients were included in this cross-sectional study. Consecutive patients examined at the Vitiligo Clinic of Andreas Sygros Hospital for Skin and Venereal Diseases, Athens, Greece, from January 2005 to December 2009 with a disease onset before the age of 12 years were included in the childhood-onset group. The later-onset group included randomly selected patients who were examined at the same period and had a disease onset after the age of 12 years. After clinical examination, a standardized questionnaire was completed for each patient. RESULTS: In all, 126 patients were included in the childhood-onset and 107 patients in the later-onset group. Childhood-onset vitiligo: (1) involved different sites at initial presentation, (2) included more cases of segmental type, and (3) was characterized by a higher prevalence of allergic diseases and a lower prevalence of thyroid diseases. Longer duration of disease and a positive family history of thyroid disease were associated with the presence of thyroid disease only in the childhood-onset group. In the later-onset group, only female sex was associated with the presence of thyroid disease. LIMITATIONS: The study was conducted in a hospital specializing in skin diseases and a selection bias toward more severe vitiligo cases is possible. CONCLUSIONS: Childhood-onset vitiligo had distinct epidemiologic and clinical characteristics, compared with later-onset disease.

Atopic dermatitis (AD) is a highly heterogeneous inflammatory disease regarding both its pathophysiology and clinical manifestations. However, it is treated according to the "one-size-fits-all" approach, which may restrict response to treatment. Thus, there is an unmet need for the stratification of patients with AD into distinct endotypes and clinical phenotypes based on biomarkers that will contribute to the development of precision medicine in AD. The development of reliable biomarkers that may distinguish which patients with AD are most likely to benefit from specific targeted therapies is a complex procedure and to date none of the identified candidate biomarkers for AD has been validated for use in routine clinical practice. Reliable biomarkers in AD are expected to improve diagnosis, evaluate disease severity, predict the course of disease, the development of comorbidities, or the therapeutic response, resulting in effective and personalized treatment of AD. Among the studied AD potential biomarkers, thymus and activation-regulated chemokine/C-C motif ligand 17 (TARC/CCL17) has the greatest evidence-based support for becoming a reliable biomarker in AD correlated with disease severity in both children and adults. In this review, we present the most prominent candidate biomarkers in AD and their suggested use.
RESUMO
In recent years, the broadening understanding of the pathogenesis of atopic dermatitis (AD) has led to the development of novel therapeutic molecules, that target core inflammatory components of the disease. The Janus kinase (JAK)/signal transducer and activation of transcription (STAT) pathway constitutes the principal signaling cascade for a large number of cytokines and growth factors and is involved in intracellular signal transduction and subsequent regulation of gene transcription. Current knowledge suggests that the robust activation of the T-helper (Th)-2 [interleukin (IL)-4, IL-5, IL-13, IL-31] and Th22 (IL-22) immune responses in both skin and serum plays a pivotal role in the immunopathogenesis of AD especially at the acute stage, followed by a variable degree of Th1 (interferon-γ, tumor necrosis factor alpha) and Th17 (IL-17) activation in chronic disease. Of note, most of the aforementioned inflammatory cytokines utilize the JAK/STAT pathway for downstream signal transduction, explaining the emerging role of JAK inhibitors in the therapeutic armamentarium of AD. The present systematic review aims to discuss the involvement of JAK/STAT pathway in the pathogenesis of AD and summarize the clinical data available on the efficacy and safety of JAK inhibitors which have been used in the treatment of AD thus far.
