RESUMO
Chronic pruritus (CP) is frequent in general medicine and the most common complaint in general dermatology. The prevalence of CP is expected to rise in the future due to the ageing population. The clinical presentation, underlying aetiology and treatment strategy of CP are heterogeneous. Also, individual treatment aims and physical, psychic and economic burdens of patients might vary. Chronic prurigo (CPG) is the most severe disease in the chronic pruritus spectrum, being associated with long-standing scratch-induced skin lesions and a therapy refractory itch-scratch-cycle. It is thus important to raise disease awareness for CP and CPG in the general public and among decision-makers in the health system. Further, there is a need to support a rational clinical framework to optimize both diagnostics and therapeutics. Currently, there is still a shortcoming regarding approved therapies and understanding CP/CPG as severe medical conditions. Therefore, the EADV Task Force Pruritus decided to publish this white paper based on several consensus meetings. The group consented on the following goals: (a) ensure that CP is recognized as a serious condition, (b) increase public awareness and understanding of CP and CPG as chronic and burdensome diseases that can greatly affect a person's quality of life, (c) clarify that in most cases CP and CPG are non-communicable and not caused by a psychiatric disease, (d) improve the support and treatment given to patients with CP to help them manage their disease and (e) publicize existing therapies including current guidelines. We aim to point to necessary improvements in access and quality of care directed to decision-makers in health policy, among payers and administrations as well as in practical care.

BACKGROUND: Itch as the most common symptom in dermatology has been shown to be related to psychological factors such as stress, anxiety and depression. Moreover, associations were found between perceived stigmatization and itch. However, studies investigating the differences between patients with dermatoses with and without itch regarding perceived stress, stigmatization, anxiety and depression are missing. Therefore, one of the aims of the second study of the European Society for Dermatology and Psychiatry (ESDaP study II) was to investigate these relationships in a large cohort of patients with different itchy dermatoses. RESULTS: 3399 patients with 14 different itchy dermatoses were recruited at 22 centres in 17 European countries. They filled in questionnaires to assess perceived stigmatization, stress, signs of clinically relevant anxiety or depression, itch-related quality of life, the overall health status, itch duration, frequency and intensity. The most significant association between the severity of itching and the perception of stress was observed among individuals with rosacea (correlation coefficient r = 0.314). Similarly, the strongest links between itch intensity and experiences of stigmatization, anxiety, and depression were found in patients with seborrheic dermatitis (correlation coefficients r = 0.317, r = 0.356, and r = 0.400, respectively). Utilizing a stepwise linear regression analysis, it was determined that within the entire patient cohort, 9.3% of the variation in itch intensity could be accounted for by factors including gender, levels of anxiety, depression, and perceived stigmatization. Females and individuals with elevated anxiety, depression, and perceived stigmatization scores reported more pronounced itch intensities compared to those with contrary attributes. CONCLUSION: This study underscores the connection between experiencing itch and its intensity and the psychological strain it places on individuals. Consequently, psychological interventions should encompass both addressing the itch itself and the interconnected psychological factors. In specific cases, it becomes imperative for dermatologists to direct individuals towards suitable healthcare resources to undergo further psychological assessment.

BACKGROUND: Dysmorphic concern is an overconcern with an imagined or slight defect in physical appearance that can be a symptom of body dysmorphic disorder (BDD). Appearance-related concerns are frequently reported by people with dermatological conditions. However, relatively little remains known about the relationship between dysmorphic concern and other variables within persons with different skin conditions. OBJECTIVES: The aim of this multicentre, cross-sectional study was to investigate gender differences regarding dysmorphic concern and the prevalence of BDD in a large sample of patients with skin conditions, in relation to sociodemographic, clinical and psychological variables. METHODS: Participants aged ≥18 years with skin conditions were consecutively enrolled in dermatological clinics of 22 European centres. Dysmorphic concern and the possible presence of BDD were measured using the Dysmorphic Concern Questionnaire (DCQ) and compared between men and women in relation to sociodemographic, clinical and psychological variables, and separately for each skin condition. RESULTS: The DCQ questionnaire was completed by 5290 dermatological patients. In all categories, mean scores were significantly higher in women than in men. Mean DCQ scores were also higher in women for most skin conditions, with the highest effect size in vitiligo. The percentage of patients who screened positive for BDD on the DCQ was 10.5%, 7.7% of men and 12.7% of women. The prevalence of BDD positive was 6.9% in patients with mild clinical severity, 11.1% for moderate and 19.1% for severe condition. In the multivariate model in patients with mild skin condition, the presence of BDD was positively associated with stress and stigma both in men and in women. CONCLUSIONS: Dysmorphic concern and BDD were more frequent in women than in men with skin conditions. Both received and actual stigmatization might have an impact on body-related concerns, in particular in women, who may be more at risk for sociocultural reasons.
RESUMO
BACKGROUND: Chronic pruritus (CP) significantly affects patients' health-related quality of life (HRQoL). Very few self-reported HRQoL questionnaires exploring CP have been developed according to international guidelines, thus limiting their use in preauthorization trials. OBJECTIVES: To develop a self-reported HRQoL questionnaire in patients with CP owing to psoriasis, atopic dermatitis, seborrhoeic dermatitis of the scalp or idiopathic dermatitis, and to explore the preliminary psychometric properties of the questionnaire. METHODS: The study was performed in France. A conceptual framework was developed based on a structured literature review and expert insight, and was improved using three focus groups involving 19 participants. A 50-item questionnaire was created and tested with 21 participants using cognitive debriefings; 11 items were removed. A cross-sectional study including 251 participants was performed to explore the preliminary psychometric properties of the 39-item questionnaire. Dimensionality was explored using principal component analysis. Cronbach's alpha and correlation coefficients (interitem, item-total score and item-dimension score) were measured. The number of items was reduced through expert consensus. RESULTS: In the 39-item version, three main dimensions were identified (Cronbach's alpha = 0·94) and all correlation coefficients were > 0·34. Upon review, 13 items were deleted owing to poor quality and six items were deleted by the team, generating a 20-item version. The questionnaire's factorial structure was best reflected with a two-dimension solution, i.e. (i) social and emotional repercussions and (ii) relation to others, fear of judgement. CONCLUSIONS: The Chronic Itch Burden Scale patient-reported questionnaire explores broad aspects of HRQoL that are relevant for patients with various skin diseases. Its good cross-sectional validity makes it useful for trials and practitioners.

Atopic dermatitis (AD) is a chronic, auto-immune condition that imposes a high burden on individuals, society, and the healthcare system. Approximately 4.4% of adults and up to 18.6% of children/adolescents have AD in Europe, with 20% of all cases accounting for moderate-to-severe forms. This form of the condition in adults results in annual societal costs across Europe of an estimated 30 billion; 15.2 billion related to missed workdays or reduced work productivity, 10.1 billion related to direct medical costs and 4.7 billion related to personal expenditure of patients/families. AD can also substantially impact physical, emotional, and social quality-of-life. Several studies have shown the debilitating itch-scratch cycle is the main cause of the multifaceted burden, as it causes substantial sleep deprivation and stigmatisation due to the physical appearance of the skin, and confidence issues. These factors lead to psychosocial issues and can cumulate over time and prohibit patients reaching their 'full life potential'. Despite this, many patients with the condition are undertreated, resulting in uncontrolled symptoms and a further strain placed on patients, society, and the economy. The authors of this White Paper comprise the European Atopic Dermatitis Working Group, which is a network of international specialists with expertise in dermatology and healthcare policy decisions. Their programme of action is focused on harnessing their expertise to build consensus, advance research, share knowledge, and ultimately seek to improve AD care outcomes through achieving long-term symptom control. This White Paper presents a systematic evaluation of the overall financial and humanistic burden of moderate-to-severe AD and the current challenges that exist with AD care. It introduces recommendations for how, collaboratively, key stakeholders and policy makers can support improvements in AD management to achieve better disease control, thus reducing the costs and associated burden placed on individuals, society, and the economy.

Atopic dermatitis (AD) is a chronic inflammatory disease, driven by type 2 inflammation. The condition manifests as moderate-to-severe disease in approximately 20% of adults with AD across Europe and is associated with a substantial burden on patients, society and healthcare systems. However, systematic assessments capturing the totality of disease burden associated with moderate-to-severe AD are limited; therefore, the overall impacts of the disease may be underestimated. A systematic literature review (SLR) was carried out to assess the overall costs of moderate-to-severe AD across Europe, including the financial, societal and humanistic impacts. PubMed, Embase and Cochrane databases were searched to identify relevant studies published between 1 January 2010 and 2 June 2020. Scientific conference proceedings, health technology assessment websites and patient association group websites were also searched for relevant information. Twenty-seven publications, corresponding to 22 unique studies, were included in the analysis. Total costs (direct and productivity losses) reached 20 695 per-person-per-year (PPPY) for adults with uncontrolled symptoms of moderate-to-severe AD. Direct medical costs ranged between 307 and 6993 PPPY; prescription medications and specialist dermatologist visits were the main contributors. Costs increased with disease severity or with uncontrolled disease. Patients with AD also incurred personal costs of 927 per year for healthcare items not reimbursed, which increased by 9% for those with moderate-to-severe forms. Annual work productivity losses comprised most of the total costs reported for adults with moderate-to-severe AD (up to 60.8% of the total burden) and were highest in those with uncontrolled disease (13 702 PPPY). Patients with moderate-to-severe disease also experienced physical, emotional, and social impacts. The overall costs of moderate-to-severe AD greatly impact on healthcare systems, patients and society. Sustained control of moderate-to-severe AD, through effective treatment and care management, is essential to limit the burden caused by the disease.

Itch is a sensation defined as the urge to scratch. The central mechanisms of itch are being increasingly studied. These studies are usually based on experimental itch induction methods, which can be classified into the following categories: histamine-induced, induction by other non-histamine chemicals (e.g. cowhage), physically induced (e.g. electrical) and mentally induced (e.g. audio-visual). Because pain has been more extensively studied, some extrapolations to itch can be proposed and verified by experiments. Recent studies suggest that the itch-processing network in the brain could be disrupted in certain diseases. This disruption could be related to the implication of new regions or the exclusion of already engaged brain regions from itch-processing network in the brain.

BACKGROUND: Acne is a long-lasting disease in adolescents and adults impacting the patient's daily life. Currently, there is no specific questionnaire that assesses its impact in adult patients. AIM: To build a self-administered questionnaire assessing the impact of acne on the daily life in adult patients. METHOD: A multidisciplinary working group was created, including 3 experts in healthcare questionnaires and dermatologists specialized in acne. A questionnaire using a standardized methodology for designing self-administered patient questionnaires according to conceptual, development and validation phases was developed. A cultural and linguistic validation into US English was conducted, based on the original French version. RESULTS: A 14-item questionnaire demonstrating consistency, reproducibility and high reliability was build. The questionnaire significantly correlated with the SF-12 mental and SF-12 physical scores and CADI, indicating good external validity. CONCLUSION: The present acne burden questionnaire AI-ADL allows the practioner to assess quickly and easily the burden of acne in patients during his daily clinical practice. Moreover, its short format allows patients to express easily and quickly their feelings and to initiate a conversation between the practioner and his patient. Thus, AI-ADL may help to better understand the multidimensional nature of acne, as well as the individual impact on the acne patient's daily life and moreover, it may play a key role in the decision-making process of treatment initiation and involvement of the patient in the management of his acne.

BACKGROUND: Sensitive skin is related to environmental factors. OBJECTIVES: We aimed to investigate the roles of poorly known associated and triggering factors on sensitive skin in a large global population. METHODS: A survey was administrated to a representative sample of the adult population aged 18-75 years in five different countries (Brazil, China, France Russia, and the United States). All participants answered a web-based questionnaire on sociodemographic characteristics, sensitive skin and environmental factors. RESULTS: Among the 10 743 included individuals (5285 men and 5458 women), 48.2% declared that they had sensitive skin. The group with sensitive skin reported significant increases in fatigue, dust or sweating and to a lesser extent food or tobacco consumption. The members of this group also declared that they experienced more sleep disorders than individuals without sensitive skin. Sensitive skin was very frequent in pregnant women, women with painful menstruations or women using contraceptive pills. CONCLUSIONS: This large cohort study identified new factors, including female hormonal status, fatigue, sleep disorders and food, associated with sensitive skin. These associations suggest that sensitive skin is not restricted to an epidermal disorder but may be included in a larger context. The identified factors are potential upstream drivers of neurogenic inflammation in sensitive skin.

BACKGROUND: In 2018 in France, overall mean health-related out-of-pocket (OOP) expenditures were 214.00/year/patient. AIM: To evaluate OOP expenditures for psoriasis patients in France. METHODOLOGY: Observational, cross-sectional, non-comparative, multicentre study in 3000 patients with clinically confirmed psoriasis who responded to a specific digital questionnaire collecting demographic and socio-economic characteristics, assessing the 3 domains (severity, psychosocial impact and past history and interventions) of the patient's Simplified Psoriasis Index (sa-SPI) and expenditures to manage psoriasis, including OOP. Multivariate linear regression was conducted to search for factors associated with higher OOP. RESULTS: In total, 2681 patients completed the questionnaire and, of those, 2562 provided clinically validated data. Overall, 60% were women; the mean age was 49.4 ± 14.8 years. 30% of the patients declared that they suffered from psoriatic arthritis. The final mean sa-SPI core was 10.86 ± 9.70. Of these 2562 patients, 243 (9.5%) had severe, 442 (17.3%) moderate and 1877 (73.3%) mild psoriasis. In addition, 932 (36.4%) patients reported facial involvement, 724 (28.25%) genital impairment and 1124 (43.8%) lesions on the limbs. Mean OOP expenditures to manage psoriasis per patient were 531.00, 439.74 ± 939.85 for patients with mild, 791.06 ± 1367.67 with moderate and 1077.64 ± 1680.14 for patients with severe psoriasis. For patients with psoriasis in the genital area, the median amount of expenditures (251.17; CI95% [138.35;363.99]) was significantly higher than that for the face (183.85; CI95% [78.76;288.94]) or limbs (199.96; CI95% [93.77;306.15); (P < 0.001). More than 90% of the patients had OOP expenditures for over-the-counter products (97.5%) and alternative care (92.0%), especially for emollients and/or hydrating products. CONCLUSION: In France, in 2019, OOP expenditures to manage psoriasis were on average more than twice as high as the overall mean health-related OOP expenditures estimated by the French Health Agency in 2018. These results should lead health authorities to review certain standards of healthcare reimbursement.

BACKGROUND: Chronic pruritus (CP) is a subjective symptom, and it is necessary to assess its intensity with validated patient-reported outcome tools in order to allow determination of the treatment course. OBJECTIVES: So far, the itch intensity scales were validated in small cohorts and in single languages. Here, we report the validation of the numerical rating scale, the verbal rating scale and the visual analogue scale for the worst and average pruritus intensity in the last 24h in several languages across Europe and across different pruritic dermatoses. METHODS: After professional translation, the intensity scales were digitized for use as a tablet computer application. Validation was performed in clinics for Dermatology in Austria, France, Germany, Italy, Poland, Russia, Spain, Switzerland and Turkey. RESULTS: A total of 547 patients with contact dermatitis, chronic nodular prurigo, psoriasis vulgaris, lichen planus or cutaneous T-cell lymphoma were included. The intensity scales showed a high level of reproducibility and inter-correlations with each other. The correlation with the Dermatology Life Quality Index was weak to strong in nearly all countries and dermatoses with the exception of France and patients with chronic nodular prurigo, for which no statistically significant correlations were found. CONCLUSIONS: The numerical rating scale, the verbal rating scale und the visual analogue scales are valid instruments with good reproducibility and internal consistency in German (Germany, Austria, Switzerland), French, Italian, Polish, Russian, Spanish and Turkish for different pruritic dermatoses. VAS worst was the best reproducible and consistent measuring instrument in all countries.

BACKGROUND: Itch is a common symptom in the general population. Affected individuals often do not seek medical consultation and rely on Internet searches to obtain information regarding their itch. OBJECTIVES: The aim of this study was to attain insights into common concerns of the general population regarding itch can by analysing itch-related Internet search behaviour. METHODS: Google AdWords Keyword Planner was used to assess search volumes for itch-related terms in 15 European countries between September 2014 and August 2018. All identified keywords were qualitatively categorized. Itch-related terms were descriptively analysed and are shown as number of searches/100 000 inhabitants. RESULTS: The search volume for the keyword 'itch' per 100 000 inhabitants was highest in Northern Europe, followed by Eastern, Central and Southern Europe. In 4/15 countries, itch was searched for more often in the autumn/winter months compared to in the spring/summer months. Most itch-related terms were related to dermatological conditions such as inflammatory skin diseases (e.g. psoriasis, atopic dermatitis), allergic or immunologic conditions (e.g. urticaria), and infectious diseases or infestations (e.g. scabies). In terms of body location, genitoanal itch dominated the searches. Symptoms and signs related to itch, possible non-dermatological aetiologies, and treatment options were also among the most searched terms. CONCLUSIONS: These analyses provided for the first time insights into the search behaviour patterns related to itch across Europe. People from Northern and Eastern Europe are more likely to seek online information regarding itch. Causes for the itch, especially dermatological conditions, and genitoanal itch are the most important concerns for Internet users. This unconventional and inexpensive method identifies medical needs of people beyond the medical setting, including people who do not seek medical consultation. Accordingly, the data could be used to guide public health interventions and manage respective inhabitants' medical needs.

AIM: To evaluate the extent to which COVID-19-related lockdown affected dermatologists. METHODS: An anonymous online survey was proposed to all French dermatologists and dermatology residents to assess the impact of COVID-19 lockdown on their professional activity, their level of stress and their psychological state, as well as their coping strategies. RESULTS: Exactly 800 dermatologists completed the survey. The respondents noted changes in behaviour in their professional and personal environment. The number of cancelled or rescheduled appointments was very high, with a huge financial impact for private practitioners. Stigmatisation was also reported. Anxiety and a feeling of increased stress were very frequent. Increased substance use was also reported. CONCLUSION: The impact of the COVID-19 pandemic and lockdown was significant for French dermatologists, with risks to their own health, profound changes in their practice, and financial and psychological impact, but also the development of new consultation and evaluation strategies to improve their work-life balance.

BACKGROUND: Corticosteroids (CS) with or without adjuvant immunosuppressant agents are standard treatment for pemphigus vulgaris (PV). The efficacy of adjuvant therapies in minimizing steroid-related adverse events (AEs) is unproven. OBJECTIVES: To utilize data collected in a French investigator-initiated, phase III, open-label, randomized controlled trial to demonstrate the efficacy and safety of rituximab and seek approval for its use in PV. METHODS: This was an independently conducted post hoc analysis of the moderate-to-severe PV subset enrolled in the Ritux 3 study. Patients were randomized to rituximab plus 0·5 or 1·0 mg kg-1 per day prednisone tapered over 3 or 6 months, or 1·0 or 1·5 mg kg-1 per day prednisone alone tapered over 12 or 18 months, respectively (according to disease severity). The primary end point was complete remission at month 24 without CS (CRoff) for ≥ 2 months, and 24-month efficacy and safety results were also reported. RESULTS: At month 24, 34 of 38 patients (90%) on rituximab plus prednisone achieved CRoff ≥ 2 months vs. 10 of 36 patients (28%) on prednisone alone. Median total cumulative prednisone dose was 5800 mg in the rituximab plus prednisone arm vs. 20 520 mg for prednisone alone. Eight of 36 patients (22%) who received prednisone alone withdrew from treatment owing to AEs; one rituximab-plus-prednisone patient withdrew due to pregnancy. Overall, 24 of 36 patients (67%) on prednisone alone experienced a grade 3/4 CS-related AE vs. 13 of 38 patients (34%) on rituximab plus prednisone. CONCLUSIONS: In patients with moderate-to-severe PV, rituximab plus short-term prednisone was more effective than prednisone alone. Patients treated with rituximab had less CS exposure and were less likely to experience severe or life-threatening CS-related AEs. What's already known about this topic? Pemphigus vulgaris (PV) is the most common type of pemphigus. Corticosteroids, a standard first-line treatment for PV, have significant side-effects. Although their effects are unproven, adjuvant corticosteroid-sparing agents are routinely used to minimize steroid exposure and corticosteroid-related side-effects. There is evidence that the anti-CD20 antibody rituximab is effective in the treatment of patients with severe recalcitrant pemphigus and in patients with newly diagnosed pemphigus. What does this study add? This study provides a more detailed analysis of patients with PV enrolled in an investigator-initiated trial. Rituximab plus prednisone had a steroid-sparing effect and more patients achieved complete remission off prednisone. Fewer patients experienced grade 3 or grade 4 steroid-related adverse events than those on prednisone alone. This collaboration between academia and industry, utilizing independent post hoc analyses, led to regulatory authority approvals of rituximab in moderate-to-severe PV.

BACKGROUND: Pruritus is a common symptom in many skin diseases. Music interventions have demonstrated their efficacy in different symptoms or diseases such as pain, depression and anxiety. OBJECTIVE: To evaluate the effects of a music intervention on pruritus. PATIENTS AND METHODS: A randomized controlled trial was conducted from November 2018 to April 2019. Fifty inpatients with pruritus intensity ≥3/10 in various chronic skin diseases were randomized in a music group or an emollient group. The primary endpoint was the evolution of pruritus as measured by the Numerical Rating Scale before and one hour after the procedure. The secondary judgement criteria were the effects on patient anxiety, the impact of pruritus on the quality of life and patient satisfaction (NCT03701971). RESULTS: Fifty patients with chronic pruritus were included, 62% were male, and the average age was 60.7 years. The most common diseases were psoriasis (N = 10), atopic dermatitis (N = 8) and contact eczema (N = 6). The average ItchyQol score was 64.8/110, showing a significant impact on quality of life. The intensity of pruritus decreased more significantly in the music intervention group than in the emollient group: 2.3 (SD 2.1) and 1.2 (SD 1.7), respectively (P < 0.05). There was a decrease in anxiety in both groups, with no statistical significant difference between groups. Among patients who received the music intervention, 64% reported feeling an improvement, 91% would recommend the music intervention, and 64% would like to continue this practice. DISCUSSION: Pruritus management is complex and requires first-line aetiological treatment. Aetiological or symptomatic treatments do not always provide enough relief; it is useful to find other therapeutic options. The music intervention has shown interest in our study. Its repeated use over the long term will be interesting to evaluate. As in pain, music may work by activating inhibitory neural circuits. The use of music is a simple method to manage chronic pruritus.

BACKGROUND: Despite the prevalence of psoriasis, the processing of itch in psoriasis and its impact on the central nervous system (CNS) remain unclear. OBJECTIVE: We studied the influence of psoriasis on the CNS using magnetic resonance imaging techniques (fMRI and DTI, respectively) to investigate whether mentally induced itch can modify the functional connectivity or the white matter microstructure of the brain. METHODS: Fourteen patients with chronic psoriasis and 15 healthy controls were recruited. Itch was mentally induced in subjects by videos showing others scratching themselves. RESULTS: The observation of functional connectivity during the viewing the video revealed an interconnected network of brain regions that are more strongly coupled in psoriasis patients than in healthy controls. This network links the cerebellum, the thalami, the anteroposterior cingulum, the inferior parietal lobules, the middle temporal poles and the parahippocampal, hippocampal, lingual and supramarginal gyri. We also found connections with the right precuneus and both left insula and superior temporal gyrus. The DTI analysis showed that chronic itch affects the microstructure of white matter, including the anterior thalamic radiations, the superior and inferior longitudinal fasciculi, the corticospinal tracts, the cingulum, the external capsules, the inferior frontal-occipital fasciculi and both minor and major forceps. CONCLUSION: Our results indicate that there could exist a network which is more interconnected in psoriasis patients. Among two building blocks of this network, the subnetwork encoding the perception and control of itch sensation is more affected than the subnetwork representing mentalizing and empathy. With an approach consisting of measuring microstructural changes at a local level in the brain, we also contradict the findings obtained with global measures which stated that chronic psoriasis cannot alter the anatomy of the brain. This confirms that itchy pathophysiological conditions have similar effects on functional and structural connectivity as those observed in chronic pain.

Sensitive skin (SS) is a syndrome defined by the occurrence of unpleasant sensations in response to stimuli that normally should not provoke such sensations. In most patients, symptoms occur within 1 h following exposure to trigger factors and may persist for minutes or even hours. Numerous triggering factors (physical, chemical or psychological) are suspected and described in articles. The aim of this article was to perform a systematic literature review to collect data on the triggering factors involved in SS and to then perform a meta-analysis. Thirteen studies were included in the systematic literature review. Subjects were classified into groups, SS or no sensitive skin (NSS), and triggering factors were researched through responses to different questions. SS could be triggered by numerous factors. The most important triggering factor was cosmetics, with an odds ratio (OR) equal to 7.12 [3.98-12.72]. Other triggering factors were physical (variations in temperature, cold, heat, wind, sun, air conditioning, wet air and dry air), chemical (water and pollution) or psychological (emotional) factors. After cosmetics, the most important factors were wet air, OR 3.83 [2.48-5.91]; air conditioning, OR 3.60 [2.11-6.14]; heat, OR 3.5 [2.69-4.63]; and water, OR 3.46 [2.56-4.77].

The special interest group on sensitive skin of the International Forum for the Study of Itch previously defined sensitive skin as a syndrome defined by the occurrence of unpleasant sensations (stinging, burning, pain, pruritus and tingling sensations) in response to stimuli that normally should not provoke such sensations. This additional paper focuses on the pathophysiology and the management of sensitive skin. Sensitive skin is not an immunological disorder but is related to alterations of the skin nervous system. Skin barrier abnormalities are frequently associated, but there is no cause and direct relationship. Further studies are needed to better understand the pathophysiology of sensitive skin - as well as the inducing factors. Avoidance of possible triggering factors and the use of well-tolerated cosmetics, especially those containing inhibitors of unpleasant sensations, might be suggested for patients with sensitive skin. The role of psychosocial factors, such as stress or negative expectations, might be relevant for subgroups of patients. To date, there is no clinical trial supporting the use of topical or systemic drugs in sensitive skin. The published data are not sufficient to reach a consensus on sensitive skin management. In general, patients with sensitive skin require a personalized approach, taking into account various biomedical, neural and psychosocial factors affecting sensitive skin.

BACKGROUND: Hair diseases play an important burden on patients' lives, causing significant emotional and psychosocial distress. However, the impairment due to different hair conditions, such as alopecia areata (AA) and androgenetic alopecia (AGA), has rarely been compared. OBJECTIVE: The aim of this study was to assess the psychological burden of subgroups of patients with different hair diseases and to compare them to a healthy population. METHODS: In this study, we analysed a subgroup of patients with hair diseases from patients of a large multicentre study including 3635 dermatological patients and 1359 controls from 13 European countries. In the subgroup of patients with hair diseases, we analysed the socio-demographic characteristics, the stress level, and the impact of hair diseases on quality of life (QoL), anxiety, and depression and we compared them among patients with AA, AGA and healthy controls. RESULTS: The study population included 115 patients (77% women, 23% men) with hair diseases, 37 of whom with AA and 20 with AGA. Patients with hair diseases had a lower education level than healthy controls (medium educational level: 43% vs. 28%). Overall, 41% of the patients reported stressful life events during the last 6 months compared with 31% of the controls. Patients with the same age, sex, depression level and comorbidities had a worse QoL when suffering from AA than from AGA (Mean Dermatology Life Quality Index score: 5.8 vs. 2.5). CONCLUSION: Patients with hair diseases are more anxious, depressed and have a lower QoL than controls.
