- Abstract
PS16 Prurigo is defined by the presence of chronic pruritus and multiple localized or generalized pruriginous lesions. The aim of this study was to assess the psychological burden of prurigo in patients of European countries. In this multicentre European study, 3, 635 general dermatology outpatients and 1, 359 controls were included. Socio-demographic data and answers to questionnaires (regarding quality of life, general health, anxiety and depression and suicidal ideation) were collected.There were 27 patients with prurigo; of these, 63% were men, and the mean age was 58.6 years. Among patients with prurigo, 10 of 27 (37%) suffered from anxiety and 8 of 27 (29%) from depression. Suicidal ideation was reported in 5 of 27 (19%) patients, and for 4 of these 5 patients, suicidal ideation was related to their skin disease. These frequencies were higher in the 10 commonest dermatological diseases (including psoriasis, atopic dermatitis and leg ulcers). The impact on quality of life was severe, with a mean Dermatologic Life Quality Index (DLQI) of 12.4, with an extreme impact on quality of life for 23% of patients and a very large impact for 27% of patients.The psychological comorbidities of prurigo are common, greater than those of other skin diseases, and their impact on quality of life is significant. Thus, it is important to study this condition and to find new treatments.

Itch is an unpleasant symptom, affecting many dermatological patients. Studies investigating the occurrence and intensity of itch in dermatological patients often focus on a single skin disease and omit a control group with healthy skin. The aim of this multi-centre study was to assess the occurrence, chronicity and intensity (visual analogue scale 0–10) of itch in patients with different skin diseases and healthy-skin controls. Out of 3,530 dermatological patients, 54.3% reported itch (mean ± standard deviation itch intensity 5.5 ± 2.5), while out of 1,094 healthy-skin controls 8% had itch (3.6 ± 2.3). Chronic itch was reported by 36.9% of the patients and 4.7% of the healthy-skin controls. Itch was most frequent (occurrence rates higher than 80%) in patients with unclassified pruritus, prurigo and related conditions, atopic dermatitis and hand eczema. However, many patients with psychodermatological conditions and naevi also reported itch (occurrence rates higher than 19%).

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. [ABSTRACT FROM AUTHOR]

Background: Chronic nodular prurigo (CNPG) is a condition characterized by chronic itch, a prolonged scratching behaviour and the presence of pruriginous nodules. A comprehensive understanding of this condition, especially regarding its clinical characteristics and impact on quality of life is still lacking. Objectives: Aim of this pan‐European multicentre cross‐sectional study was to establish the clinical profile of CNPG, including its associated burden. Methods: Fifteen centres from 12 European countries recruited CNPG patients presenting at the centre or using the centres' own databases. Patients were asked to complete a questionnaire in paper or electronic format. Demography, current co‐morbidities, underlying disease, itch intensity, additional sensory symptoms, quality of life, highest burden and emotional experience of itch were assessed. Results: A total of 509 patients (210 male, median age: 64 years [52; 72]) were enrolled. Of these, 406 reported itch and CNPG lesions in the previous 7 days and qualified to complete the whole questionnaire. We recorded moderate to severe worst itch intensity scores in the previous 24 h. Scores were higher in patients with lower educational levels and those coming from Eastern or Southern Europe. Most patients experience itch often or always (71%) and report that their everyday life is negatively affected (53%). Itch intensity was considered to be the most burdensome aspect of the disease by 49% of the patients, followed by the visibility of skin lesions (21%) and bleeding of lesions (21%). The majority of patients was unaware of an underlying condition contributing to CNPG (64%), while psychiatric diseases were the conditions most often mentioned in association with CNPG (19%). Conclusions: This multicentre cross‐sectional study shows that itch is the dominant symptom in CNPG and reveals that the profile of the disease is similar throughout Europe. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

ITCHING ,DELPHI method ,TASK forces - Abstract
Background: Chronic prurigo (CPG) is a distinct disease characterized by chronic pruritus, history and/or signs of prolonged scratching and multiple pruriginous lesions. It may present with various clinical manifestations, including papules, nodules, plaques or umbilicated lesions. Some patients with chronic pruritus show pruriginous linear and scaring scratch lesions (LSSL) and it is unclear whether these lesions belong to the spectrum of CPG. Objective: To achieve a consensus on the classification of pruriginous LSSL and establish criteria to differentiate them from similar appearing conditions of different nature. Methods: Members of the Task Force Pruritus (TFP) of the European Academy of Dermatology and Venereology participated in the consensus conference, discussing representative clinical cases. Using the Delphi method, consensus was reached when ≥75% of members agreed on a statement. Results: Twenty‐one members of the TFP with voting rights participated in the meeting. It was consented that LSSL occurs due to chronic pruritus and prolonged scratching, and share common pathophysiological mechanisms with CPG. LSSL were thus considered as belonging to the spectrum of CPG and the term 'linear prurigo' was chosen to describe this manifestation. Conclusion: Considering linear prurigo as belonging to the spectrum of CPG has important clinical implications, since both the diagnostic and therapeutic approach of these patients should be performed as recommended for CPG. Importantly, linear prurigo should be differentiated from self‐inflicted skin lesions as factitious disorders or skin picking syndromes. In the latter, artificial manipulation rather than pruritus itself leads to the development of cutaneous lesions, which can show clinical similarities to linear prurigo. [ABSTRACT FROM AUTHOR]

Background Acne is a very common skin condition, and it is of great interest to elucidate lifestyle factors that may contribute to its occurrence. In the last decade, the acne-diet connection has been brought back to credibility. Objective To examine whether high intakes of dairy products in early adolescence is associated with moderate to severe acne in later adolescence. Methods The study is a longitudinal, questionnaire-based population study of Norwegian adolescents. Students attending the 10th grade (15-16 years old) of compulsory schooling in Oslo in 2000-2001 and the 13th grade (18-19 years old) 3 years later, in 2004, were invited. Dairy product consumption was self-reported at age 15-16 and acne severity was self-assessed and reported at age 18-19. Results The overall prevalence of moderate to severe acne was 13.9%. High intakes (≥2 glasses per day) of full-fat dairy products were associated with moderate to severe acne. In boys with exclusively high intakes of full-fat dairy products, the odds ratio for acne was 4.81 (1.59-14.56). A high total intake of dairy products was associated with acne in girls ( OR 1.80, 1.02-3.16). No significant associations were found between acne and intake of semi-skimmed or skimmed dairy products, and not with moderate intakes of any fat variety of dairy products. Conclusion This study shows association between high intakes of dairy products and acne in adolescence. Our findings support a hypothesis suggesting that dairy consumption may be a factor contributing to acne. The study is based on multiple hypothesis testing, and the methodological limitations must be considered when interpreting the results. [ABSTRACT FROM AUTHOR]
