The classification of self-inflicted skin lesions proposed by the European Society for Dermatology and Psychiatry (ESDaP) group generated questions with regard to specific treatments that could be recommended for such cases. The therapeutic guidelines in the current paper integrate new psychotherapies and psychotropic drugs without forgetting the most important relational characteristics required for dealing with people with these disorders. The management of self-inflicted skin lesions necessitates empathy and a doctor-patient relationship based on trust and confidence. Cognitive behavioural therapy and/or psychodynamic and psychoanalytic psychotherapy (alone, or combined with the careful use of psychotropic drugs) seem to achieve the best results in the most difficult cases. Relatively new therapeutic techniques, such as habit reversal and mentalization-based psychotherapy, may be beneficial in the treatment of skin picking syndromes. [ABSTRACT FROM AUTHOR]

Sensitive skin is a frequent complaint in the general population, in patients, and among subjects suffering from itch. The International Forum for the Study of Itch (IFSI) decided to initiate a special interest group (SIG) on sensitive skin. Using the Delphi method, sensitive skin was defined 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. These unpleasant sensations cannot be explained by lesions attributable to any skin disease. The skin can appear normal or be accompanied by erythema. Sensitive skin can affect all body locations, especially the face". This paper summarizes the background, unresolved aspects of sensitive skin and the process of developing this definition.

Chronic itch affects millions of patients worldwide and has a significant impact on quality of life. The assessment of itch and its associated effects is a significant compo-nent of clinical practice in itch management. Despite itch being a common complaint, there are few studies descri-bing the use of structured questionnaires for evaluation and measurement of itch and its sensory and affective dimensions. The International Society of the Study of Itch (IFSI) has recently provided invaluable data on the use of visual analogue scales as an assessment tool for itch. However, it is clear that additional tools are needed to better assess the different dimensions of chronic itch and better tailor management. With this goal in mind, a Special Interest Group was initiated by members of IFSI to determine which of the various psychometric properties of itch questionnaires offer the greatest uti-lity in the evaluation of chronic itch. This first consen-sus paper addresses what domains and structure of itch questionnaires need to be implemented to better assess chronic itch and guide therapy. [ABSTRACT FROM AUTHOR]

Medical adhesive tapes are commonly recommended for the prevention of friction blisters during hiking and military marches. The aim of this paper is to report on the results of investigations into an outbreak of taperelated foot dermatitis in 26 military conscripts following continuous use of medical adhesive tapes for several days during a field exercise. Patch tests were performed using baseline series and aimed testing was performed with colophonium-related substances and different medical adhesive tapes. Contact allergy to the adhesive tapes used was found in 20 (77%) subjects, and contact allergy to colophonium in 16 (61%). Chemical analysis detected colophonium-related substances in the culprit tapes. Compared with consecutive dermatitis patients investigated at our Department of Occupational and Environmental Dermatology in the previous 10 years, conscripts with colophonium allergy had increased odds ratios for concomitant contact allergy to phenol formaldehyde resins and fragrance substances including hydroperoxides of limonene and linalool. The results show that prolonged use of medical adhesive tapes on intact skin carries a high risk for allergic contact dermatitis. Prior to their introduction on the market, medical devices should be assessed for possible side-effects. [ABSTRACT FROM AUTHOR]

The terminology, classification, diagnosis and treatment of self-inflicted dermatological lesions are subjects of open debate. The present study is the result of various meetings of a task force of dermatologists, psychiatrists and psychologists, all active in the field of psychodermatology, aimed at clarifying the terminology related to these disorders. A flow chart and glossary of terms and definitions are presented to facilitate the classification and management of self-inflicted skin lesions. Several terms are critically discussed, including: malingering; factitious disorders; Miinchausen's syndrome; simulation; pathomimicry; skin picking syndrome and related skin damaging disorders; compulsive and impulsive skin picking; impulse control disorders; obsessive compulsive spectrum disorders; trichotillomania; dermatitis artefacta; factitial dermatitis; acne excoriée; and neurotic and psychogenic excoriations. Self-inflicted skin lesions are often correlated with mental disorders and/or pathological behaviours, thus it is important for dermatologists to become as familiar as possible with the psychiatric and psychological aspects underlying these lesions.

Chronic itch is a common and distressing symptom that arises from a variety of skin conditions and systemic diseases. Despite this, there is no clinically based classification of pruritic diseases to assist in the diagnosis and cost-effective medical care of patients with pruritus. The proposed classification focuses on clinical signs and distinguishes between diseases with and without primary or secondary skin lesions. Three groups of conditions are proposed: pruritus on diseased (inflamed) skin (group I), pruritus on non-diseased (non-inflamed) skin (group II), and pruritus presenting with severe chronic secondary scratch lesions, such as prurigo nodularis (group lII). The next part classifies the underlying diseases according to different categories: dermatological diseases, systemic diseases including diseases of pregnancy and drug-induced pruritus, neurological and psychiatric diseases. In some patients more than one cause may account for pruritus (category "mixed") while in others no underlying disease can be identified (category "others"). This is the first version of a clinical classification worked out by the members of the international Forum for the Study of itch. it is intended to serve as a diagnostic route for better evaluation of patients with chronic pruritus and aims to improve patients' care.

Capillary malformation-arteriovenous malformation syndrome is a rare genodermatosis with cutaneous capillary malformations and a risk of associated fast-flow malformations. We describe here a four-generation family with a novel heterozygous pathogenic variant in the EPHB4 gene (NM_004444.5 (EPHB4): c.2224G>C, p.(Ala742Pro)). A review of the literature retrieved 127 patients with capillary malformation-arteriovenous malformation syndrome and confirmed variants in EPHB4. Multiple capillary malformations were present in 114 (89.76%) patients, and 12 (9.44%) patients had a solitary capillary malformation. Arteriovenous malformations/fistulas were present in 23 (18.1%) patients, and were located within the central nervous system in 5 (3.9%) patients. Not all papers included description of epistaxis. Telangiectasias were reported in 28 (22%) patients, and Bier spots were described in 20 (15.7%) patients. The clinical characteristics of capillary malformation-arteriovenous malformation syndrome are diverse and often discrete, which can make it difficult to distinguish capillary malformationarteriovenous malformation syndrome from hereditary haemorrhagic telangiectasia.

Research interest in dermoscopy is increasing, but the complete dermoscopic image sets used in inter-observer studies of skin tumours are not often shared in research publications. The aim of this systematic review was to analyse what proportion of images depicting skin tumours are published in studies investigating inter-observer variations in the assessment of dermoscopic features and/or patterns. Embase, MEDLINE and Scopus databases were screened for eligible studies published from inception to 2 July 2020. For included studies the proportion of lesion images presented in the papers and/or supplements was extracted. A total of 61 studies (53 original studies and 8 shorter reports (i.e. research letters or concise reports)). published in the period 1997 to 2020 were included. These studies combined included 14,124 skin tumours, of which 373 (3%) images were published. This systematic review highlights that the vast majority of images included in dermoscopy research are not published. Data sharing should be a requirement for future studies, and must be enabled and standardized by the dermatology research community and editorial offices. [ABSTRACT FROM AUTHOR]

Linear IgA bullous dermatosis (LABD) is a rare subepidermal autoimmune blistering disease characterized by linear deposition of IgA along the basement membrane zone. Although most reported cases are idiopathic, there is a subset of patients with drug-induced LABD. Various drugs have been associated with the drug-induced form of the disease. This paper reviews the literature on drugs reported to elicit linear IgA dermatosis and its specific clinical presentation. In addition, a case report of a 77-year-old male patient with linear IgA dermatosis induced by vancomycin is described. The aim of this paper is to emphasize the need to include this differential diagnosis in cases of suspected adverse drug reactions, as well as to highlight the role of drugs in LABD.

In shared decision making (SDM) patients and physicians make treatment decisions together based on the best available evidence and the values and preferences of patients. SDM is very suitable for use in dermatological practice, but is infrequently applied by dermatologists. To support the application of SDM in dermatology we developed Decision Cards: 1-page overviews of possible treatment options, for use during a patient- physician consultation. Decision Cards provide answers to patients' most frequently asked questions, based on (inter)national guidelines, Summary of Product Characteristics, relevant literature, and clinical expertise. Three evidence-based Decision Cards were developed: 1 for biologicals or apremilast in psoriasis, and 2 for atopic eczema (1 for topical, photo- or systemic therapy, and 1 for systemic therapy only). More cards for psoriasis are currently in development. Patients, dermatologists and researchers collaborated in the development of the Decision Cards. This paper shares the framework used for the development of the Decision Cards, in order to support others in the development process. [ABSTRACT FROM AUTHOR]

Cutaneous melanoma arises from melanocytes following genetic, epigenetic and allogenetic (i.e. other than epi/genetic) modifications. An estimated 10% of cutaneous melanoma cases are due to inherited variants or de novo mutations in approximately 20 genes, found using linkage, next-generation sequencing and association studies. Based on these studies, 3 classes of predisposing melanoma genes have been defined based on the frequency of the variants in the general population and lifetime risk of developing a melanoma: (i) ultra-rare variants with a high risk, (ii) rare with a moderate risk, and (iii) frequent variants with a low risk. Most of the proteins encoded by these genes have been shown to be involved in melanoma initiation, including proliferation and senescence bypass. This paper reviews the role(s) of these genes in the transformation of melanocytes into melanoma. It also describes their function in the establishment and renewal of melanocytes and the biology of pigment cells, if known. [ABSTRACT FROM AUTHOR]

Superficial fungal infections have been known for hundreds of years. During the 20th century new diagnostic methods were developed and the taxonomy changed several times, which, unfortunately, resulted in many fungi having several names (synonyms). The taxonomy is important, as species-specific identification guides clinicians when choosing the most appropriate antifungal agent, and provides an indication of the source of infection (anthropophilic, zoophilic or geophilic). Traditional diagnostic tests (direct microscopy, culture and histopathology) are still widely used, but molecular-based methods, such as PCR, have many advantages, and increasingly supplement or replace conventional methods. Molecular-based methods provide detection of different genus/species spectra. This paper describes recent changes in dermatophyte taxonomy, and reviews the currently available diagnostics tools, focusing mainly on commercially available PCR test systems.

Beginning from embryological development, skin and psyche are closely related to physiological state regardless of age. Altering the homeostasis of one of these components impacts on the other, thereby substantiating that the relationship between itch and psyche is bilateral. Itch has a complex pathogenesis, which involves the peripheral and central nervous systems, as well as various inflammatory mediators. This paper reviews key aspects of itch pathogenesis, relevant associations with stress, the contagiousness of itch, psychological and psychiatric considerations related to itch, and the burden of itch with respect to impairment of health-related quality of life (HRQoL) and stigmatization. Despite the fact that itch--psyche associations still pose many questions, current knowledge supports the role of a holistic, interdisciplinary approach to these patients in order to improve their well-being.

Nail-patella syndrome is an autosomal dominant disorder characterized by nail dysplasia and skeletal anomaly. Some patients have been shown to have ultrastructural abnormalities of the glomerular basement membrane that result in nephrosis. However, little has been reported on the epidermal basement membrane in this condition. This paper reports 2 families with nail-patella syndrome. Direct sequencing analysis of LMX1B revealed that family 1 and family 2 were heterozygous for the mutations c.140-1G>C and c.326+1G>C, respectively. To evaluate the epidermal basement membrane zone, ultrastructural and immunohistochemical analyses were performed using skin specimens obtained from the dorsal thumb. Electron microscopy showed intact hemidesmosomes, lamina lucida, lamina densa, and anchoring fibrils. Immunofluorescence studies with antibodies against components of the epidermal basement membrane zone revealed a normal expression pattern among the components, including type IV collagen. These data suggest that nail dysplasia in patients with nail-patella syndrome is not caused by structural abnormalities of the epidermal basement membrane. [ABSTRACT FROM AUTHOR]

Studies demonstrating the negative impact of paediatric psoriasis on health-related quality of life (HRQOL) are accumulating, but little is known about moderators of HRQOL. The objectives of this review were to summarize studies on HRQOL in paediatric psoriasis and to explore the potential moderating influences of demographic and clinical variables. Searches were conducted by 2 independent researchers in PubMed, Embase, CINAHL, PsycINFO, and Scopus for papers published between 1995 (the date the first dermatology-specific HRQOL-instrument for children was introduced) and 2016. Eligible studies were required to report HRQOL data for children and/or adolescents with psoriasis (4-18 years) using validated HRQOL questionnaires. Seventeen eligible studies (number of patients = 1,185) were identified. Moderation analyses revealed that study samples with a higher percentage of girls were associated with better HRQOL (β = 0.19), while a higher mean age of onset (β = 0.83) and study quality (β = 0.28) were associated with lower HRQOL (all p<0.05). Several papers did not provide the information necessary for exploring between-study differences, thus the moderation analysis results should be interpreted with caution. In conclusion, children and adolescents with psoriasis experience moderate impairment of HRQOL. Certain demographic characteristics (e.g. sex) and clinical characteristics (e.g. age at onset) appear to moderate this impact. [ABSTRACT FROM AUTHOR]

Gorlin syndrome comprises multiple basal cell carcinomas (BCCs), basal cell naevi (BCNs), odontogenic keratocysts, skeletal abnormalities and other features (1). Identification of the PTCH1 gene as the candidate gene for Gorlin syndrome demonstrated that activation of the Hedgehog (Hh) pathway is the key driver in the physiology and pathology of BCC formation (2). Gorlin syndrome has been linked to germline mutations of various members of the Hh pathway, including mainly PTCH1 and also PTCH2 and SUFU; however, to date, SMO germline mutations have not been described. Recently, a case of Gorlin syndrome type 1 mosaicism presented a somatic mutation of SMO L412F (3). This mutation has been described as oncogenic, conferring constitutive activation of the Hh pathway (4). This paper describes a second case of Gorlin syndrome mosaicism with the same SMO L412F mutation observed in affected skin. A detailed molecular assessment of multiple BCNs and BCCs was performed to analyse the oncogenic steps of BCC formation in this patient. [ABSTRACT FROM AUTHOR]

The aim of this study was to assess the knowledge and influence of predatory journals in the field of dermatology in Austria. A total of 286 physicians (50.5% men) completed a questionnaire. The vast majority of subjects read scientific articles (n = 281, 98.3%) and took them into consideration in their clinical decisionmaking (n = 271, 98.5% of participants that regularly read scientific literature). Open access was known by 161 (56.3%), predatory journals by 84 (29.4%), and the Beall's list by 19 physicians (6.7%). A total of 117 participants (40.9%) had been challenged by patients with results from the scientific literature, including 9 predatory papers. Participants who knew of predatory journals had a higher level of education as well as scientific experience, and were more familiar with the open-access system (p < 0.001). These results indicate that the majority of dermatologists are not familiar with predatory journals. This is particularly the case for physicians in training and in the early stages of their career.

In this open, controlled, multicentre and prospective observational study, smartphone teledermoscopy referrals were sent from 20 primary healthcare centres to 2 dermatology departments for triage of skin lesions of concern using a smartphone application and a compatible digital dermoscope. The outcome for 816 patients referred via smartphone teledermoscopy was compared with 746 patients referred via the traditional paper-based system. When surgical treatment was required, the waiting time was significantly shorter using teledermoscopy for patients with melanoma, melanoma in situ, squamous cell carcinoma, squamous cell carcinoma in situ and basal cell carcinoma. Triage decisions were also more reliable with teledermoscopy and over 40% of the teledermoscopy patients could potentially have avoided face-to-face visits. Only 4 teledermoscopy referrals (0.4%) had to be excluded due to poor image quality. Smartphone teledermoscopy referrals allow for faster and more efficient management of patients with skin cancer as compared to traditional paper referrals. [ABSTRACT FROM AUTHOR]

Prostanoids, including prostaglandins (PGs) and thromboxane A2 (TXA2), are a family of lipid-derived autacoids that modulate many physiological systems and pathological contexts. Prostanoids are generated by sequential metabolism of arachidonic acid, catalysed by cyclo-oxygenase, to PGH2, which is then converted to PGD2, PGE2, PGF2α, PGI2 and TXA2, catalysed by their specific synthases. Recent evidence suggests that prostanoids play a role in regulating hair growth. The PGF2α analogue is Food and Drug Administrationapproved in the US and routinely used to enhance the growth of human eyelashes. PGE2 is reported to protect from radiation-induced hair loss in mice. Conversely, PGD2 inhibits hair growth. This paper reviews the metabolism of prostanoids and the expression pattern of prostanoid receptors in hair follicles, focussing on their different and opposing effects on hair growth and the underlying mechanisms. This has potential clinical relevance in the treatment and prevention of hair disorders. [ABSTRACT FROM AUTHOR]

In order to improve diagnosis and treatment, physicians require information about the social context and quality of life of their patients. The Center for Chronic Pruritus at the University Hospital Münster achieves this goal using the electronic patient-reported outcome system "Mobile Patient Survey", which assesses pruritus and quality of life measures. The aim of this study is to evaluate the consistency and reliability of such measures. A total of 42 patients, age range 19-82 years, participated in the study and were asked to assess the measures at baseline via a paper questionnaire, and to use the "Mobile Patient Survey" at baseline and after 1 h in order to test reliability. Statistical analysis was performed using coefficient rc for metric variables and weighted kappa κw for categorical vari- ables. The internal consistency of all measures was unaffected. It was shown that 6 out of 7 measures can be assessed without loss of reliability. It is recommended that questionnaires for electronic usage are assessed for validity and reliability.

Although wool is commonly believed to cause irritant (non-immune) and hypersensitivity (immune) cutaneous reactions, the evidence basis for this belief and its validity for modern garments have not been critically examined. Publications from the last 100 years, using MEDLINE and Google Scholar, were analysed for evidence that wool causes cutaneous reactions, both immune-mediated (atopic dermatitis exacerbation, contact urticaria, allergic contact dermatitis) and non-immune-mediated (irritant contact dermatitis, itch). Secondary aims of this paper were to examine evidence that lanolin and textile-processing additives (formaldehyde, chromium) cause cutaneous reactions in the context of modern wool-processing techniques. Current evidence does not suggest that wool-fibre is a cutaneous allergen. Furthermore, contact allergy from lanolin, chromium and formaldehyde is highly unlikely with modern wool garments. Cutaneous irritation from wool relates to high fibre diameters (= 30-32 µm). Superfine and ultrafine Merino wool do not activate sufficient c-fibres to cause itch, are well tolerated and may benefit eczema management. [ABSTRACT FROM AUTHOR]

Performing a reliable assessment of chronic pruritus remains a challenge. Electronic diaries are often used, but many of the scales have not been validated. ItchApp© was developed for Android smartphones in order to address this lack. A total of 40 subjects with chronic pruritus completed questionnaires both on paper and with ItchApp© (verbal rating scale, numerical rating scale, dynamic pruritus score) in order to validate the software application. Strong correlations were found for test–retest reliability (intraclass correlation coefficient: 0.865-0.977) and convergent validity (Spearman's r: 0.442-0.924). A feasibility questionnaire for ItchApp© revealed a high level of user friendliness and compliance. This was confirmed in a randomized controlled trial with 68 subjects, for which the clinically important difference in the numerical rating scale values for ItchApp© was calculated (2.61 points). In summary, ItchApp© is a recently developed eDiary that can provide experts with a reliable evaluation of patients with chronic pruritus. It will be made available for future clinical trials.

Pruritus occurs frequently in the elderly population, but it has not been fully defined and its precise prevalence is unknown. Putative causes of pruritus are numerous and patients' quality of life can be greatly reduced. In the absence of any specific cause, a diagnosis of senile pruritus is proposed, suggesting that itch is secondary to ageing. However, the relationship of pruritus with skin ageing and/or neuronal ageing and/or immune ageing is poorly understood. Many treatments have been reported, but are poorly effective. This paper reviews the literature on senile pruritus, in order to improve understanding of this condition and to enable improved diagnosis and treatment. [ABSTRACT FROM AUTHOR]

Malignant tumours are the foremost complications of immunosuppressive treatment. They are a major challenge for organ transplant recipients and their treating physicians. This paper reviews the aetiology and current treatment of an unusual neuroendocrine skin cancer, Merkel cell carcinoma (MCC), caused by a Merkel cell polyomavirus infection. MCC occurs more frequently than expected in immunosuppressed subjects, especially in organ transplant recipients. The current literature comprises reports of 79 organ transplant recipients with MCC. The risk of MCC in organ transplant recipients is increased up to 66-182-fold compared with the general population. In addition to the increased risk of developing MCC, immunosuppressed individuals have poorer MCC-specific survival. The aim of this review article is to familiarize organ transplant doctors with this unique and clinically challenging skin cancer, and to provide recent data on the diagnosis and current treatment recommendations for an immunosuppressed population.

In the 1990s, 5-flourouracil (5-FU) was introduced as a treatment for keloids; however, there is still no consensus on its use. In order to guide clinical practice, a systematic review of the clinical evidence on the effectiveness of 5-FU in keloid treatment was carried out. Eight databases were searched on 10 September 2014 using the terms "keloid" and "5-FU", together with all synonyms of these terms. Two reviewers selected original research reports using 5-FU alone or combined with a maximum of 2 other therapies. Eighteen papers were found that reported either on intralesional 5-FU alone, or on 5-FU combined with triamcinolone acetonide (TAC:5-FU) or excision, including 482 patients. 5-FU treatment was effective in 45–96% of patients, but only TAC:5-FU may perform better than TAC alone. Due to a poor level of evidence, further research should establish the superiority of repeated intralesional TAC:5-FU injections over TAC alone with several doses and injection schedules.

In clinical practice, the term "paraneoplastic itch" is used to describe itch in patients with cancer. Patients with hematological or solid tumor malignancies can be affected. In general, paraneoplastic itch is considered a rare disorder. However, paraneoplastic itch in hematological malignancies such as polycythemia vera and lymphoma are relatively frequent while other forms of paraneoplastic itch are in fact extremely rare. The true frequency of this symptom is unclear, epidemiological data in this field are limited. Itch in malignant disease may additionally impair patients' quality of life. A population-based cohort study showed that chronic itch without concomitant skin changes is a risk factor for having undiagnosed hematologic and bile duct malignancies. Paraneoplastic itch is rather resistant to treatment. In 2012, an interdisciplinary interest group of physicians and researchers was founded, aiming to generate a clear definition of paraneoplastic itch. In this paper we briefly review the current knowledge and aim to define what can be summarized under the term "paraneoplastic itch". [ABSTRACT FROM AUTHOR]

In the absence of Nordic-wide guidelines on the best practice management of psoriasis, this paper aims to provide Nordic recommendations for treatment goals, evaluation of quality of life impact and assessment/management of co-morbidities. This Delphi approach consisted of telephone interviews, local Nordic face-to-face meetings, and a Nordic-wide meeting, in which questions on treatment goals, quality of life impact and assessment/management of co-morbidities were posed to 17 dermatologists with psoriasis-treatment experience to gain consensus (≥90% agreement). The dermatologists agreed on the individualisation of treatment goals using Psoriasis Area and Severity Index and Dermatology Life Quality Index, which should be measured at the same frequency. Training of healthcare professionals on the use of these tools and psychological assessments were considered important, along with the referral of psoriasis patients with cardio-metabolic risk factors to their general practitioner. In order to achieve the best practice management of psoriasis, Nordic dermatologists should be trained and adhere to these recommendations in conjunction with available treatment guidelines.

Psoriasis is a multifactorial chronic inflammatory disease. Monogenic psoriasis has been described recently, including dominantly inherited plaque and generalized pustular types, related to activating mutations in the CARD14 gene. We describe here a family with CARD14-related psoriasis, exhibiting an extreme variability of clinical presentation (from mild plaque-type to generalized pustular psoriasis) and early disease onset. The affected family members harboured the c.349G>A [p.Gly117Ser] mutation in CARD14, which has not previously been linked to pustular psoriatic phenotype. Furthermore, most severely affected individuals carried 3 additional CARD14 coding region polymorphisms (rs2066964, rs34367357 and rs11652075), suggesting their possible effect on disease expression. Early-onset psoriasis co-segregated with the HLA-C*0602, indicating that HLA-C*0602 could potentially modulate the time of disease onset. In summary, this paper describes a family with CARD14-related psoriasis and discusses the possible influence of the specific haplotypes on intrafamilial variation in the clinical phenotype of the disease.

The aim of this study was to analyse factors associated with remission of atopic dermatitis (AD) in childhood. A population-based AD cohort of 894 children aged 1-3 years from a cross-sectional baseline study in 2000 was followed up in 2005. The association between remission, background, health, lifestyle, and environmental variables was estimated with crude and multivariable logistic regression. At follow-up, 52% of the children had remission. Independent factors at baseline predicting remission were: milder eczema (adjusted odds ratio (aOR), 1.43; 95% confidence interval (95% CI) 1.16-1.77); later onset of eczema (aOR 1.40; 95% CI 1.08-1.80); non-flexural eczema (aOR 2.57; 95% CI 1.62-4.09); no food allergy (aOR 1.51; 95% CI 1.11-2.04), and rural living (aOR 1.48; 95% CI 1.07-2.05). Certain aspects of AD and rural living were important for remission, but despite the initial hypotheses to the contrary, the environ mental factors examined in this paper were not substantial predictors of remission.

Chronic hand eczema places a heavy burden on patients, often affecting their ability to work. This paper compares the cost-of-illness and treatment approaches for patients with refractory chronic hand eczema, in relation to whether the disease was occupational or unrelated to work factors. Data from 2 surveys, comprising 310 patients with chronic hand eczema insured by German statutory health insurance (SHI) (including work-impaired patients, work-unaffected patients and non-working patients) and known work-related chronic hand eczema insured by occupational health insurance (OHI). Annual healthcare costs of managing work-impaired patients (SHI) and patients with work-related chronic hand eczema (OHI) were €3,164 and €3,309, respectively, approximately double the costs of managing non-working and work-unaffected (SHI) patients. This analysis shows that the costs associated with chronic hand eczema are affected by the correlation of chronic hand eczema with work, with costs being higher for occupational patients with chronic hand eczema.

Chronic pruritus is a common symptom and there is an urgent need to test new anti-pruritic substances in highquality clinical trials. However, no widely accepted standardized and validated method for objectively measuring pruritus is yet available. A special interest group of the International Forum for the Study of Itch has been established to assess scoring methods and questionnaires for use in clinical trials. This paper presents our current recommendations. The set of measures we recommend includes pruritus intensity scales, instruments for assessment of scratch lesions, chronic pruritus course, quality of life and patient benefitsen.

This paper reports survey-based data on the diagnosis and management of genital herpes simplex virus (HSV) infection in 14 countries of the Eastern European Network for Sexual and Reproductive Health (EE SRH). Only 43% of the countries could provide the number of genital HSV cases recorded at national level. Eighty-six percent of countries employed syndromic management in cases of genital ulcer disease. Most countries performed type-specific and/or non-type-specific enzyme immunoassays to detect HSV antibodies. Non-type-specific serology for diagnostic purposes should be actively discouraged. Direct detection methods for HSV, such as PCR, antigen detection and culture, are available in the region, but their usage was extremely low. Their use in Eastern European countries should be actively promoted. The availability of laboratory services must be improved, and countries in the region should implement consensus recommendations for the laboratory diagnosis of genital HSV infections in order to improve clinical practice.

Our clinical experience has suggested that the presently recommended patch-test concentration (1.0%) for formaldehyde in the baseline series might be too low. Therefore, consecutively patch-tested dermatitis patients were tested simultaneously with formaldehyde 1.0% and 2.0% (w/v) in aqua. Formaldehyde 1.0% and 2.0% were applied with a micro-pipette (15 μl) to filter paper discs in Finn Chambers (0.30 mg/cm² and 0.60 mg/cm², respectively). A total of 1397 patients with dermatitis were patchtested. In all, 68 (4.9%) patients reacted positively to formaldehyde; 37 reacted only to 2.0%, 29 reacted to both concentrations, and 2 reacted only to 1.0%. Significantly more patients were thus diagnosed with contact allergy to formaldehyde 2.0% compared with 1.0% (p<0.001). We detected 0.1%, 0.4%, and 29.6% irritant reactions to 1.0%, 2.0%, and 3.0% formaldehyde, respectively. We conclude that, with an optimized patch-test technique, doubling the dose per area detects significantly more contact allergies to formaldehyde, but an even higher test concentration causes too many irritant reactions to be usable.

Congenital ichthyosis is often associated with typical neonatal phenotypes, "Collodion baby" and "Harlequin foetus", later transforming into severe lamellar or erythrodermic ichthyosis. However, in a minority of cases the skin condition will improve spontaneously after birth, although slight scaling, xerosis, hypohidrosis and keratoderma usually persist. Some of these patients will eventually be diagnosed as suffering from self-improving collodion ichthyosis, ichthyosis prematurity syndrome, or other, even rarer, forms of ichthyosis also characterized by a phenotypic shift in early childhood. This paper summarizes newly described aetiologies for some of these diseases and discusses difficulties encountered when trying to distinguish them clinically from other types of autosomal recessive congenital ichthyosis. To remind health providers about this heterogeneous group of partially transient disorders of cornification, a new umbrella term, "pleomorphic ichthyosis", is proposed. [ABSTRACT FROM AUTHOR]

Psoriasis is a chronic inflammatory skin disease, which affects approximately 2.6% of the population in Northern Europe and Scandinavia. To achieve disease control, combinations of systemic treatments are sometimes needed for variable time periods. However, no evidence-based guidelines exist for the use of systemic combination therapy. Therefore, the aim was to review the current literature on systemic anti-psoriatic combination regimens. We searched PubMed, and identified 98 papers describing 116 studies (23 randomized) that reported on the effect of various systemic combination treatments. The most thoroughly investigated combination was retinoid and phototherapy. Further controlled research is needed to define the safest and most effective combination regimens. [ABSTRACT FROM AUTHOR]

There are substantial difficulties involved in carrying out clinical studies of recurrent herpes labialis, since the disease has a rapid onset, short-lasting viral shedding period and is rapidly self-healing. The aim of this paper was to critically assess published reports of episodic treatment of herpes labialis and to review biological and methodological problems involved in such studies. Limited, but statistically significant, results have been shown with topical antivirals, such as acyclovir and penciclovir, improving healing times by approximately 10%. Orally administrated antivirals, such as valaciclovir and famciclovir, have subsequently found clinical use. However, these two oral medications have different profiles in phase 3 studies. Famciclovir showed additional improvement of efficacy in terms of lesion healing time, but no effect on prevention of ulcerative lesions, while valaciclovir appeared to have similar efficacy to that of acyclovir cream on lesion healing, but some additional efficacy with respect to prevention of ulcerative lesions. A formulation of acyclovir/hydrocortisone showed further improvement in prevention of ulcerative lesions, while retaining efficacy with respect to lesion healing. [ABSTRACT FROM AUTHOR]

Scleromyxoedema is a rare disease of unknown aetiology that is characterized by progressive cutaneous mucinosis and paraproteinaemia. A variety of systemic (e.g. gastro-intestinal, neurological, pulmonary, cardiac and renal) complications may lead to significant morbidity and mortality necessitating therapeutic intervention. The latter remains challenging. Numerous treatment modalities have been reported in the literature, often, however, with inconsistent responses, frequent relapses and potentially serious side-effects. Moreover, the rarity of sclero-myxoedema has prevented the execution of controlled therapeutic trials. This paper discusses current proposed therapeutic strategies and reports the case of a 64-year-old male patient with progressive scleromyxoedema associated with IgG-λ paraproteinaemia in whom monthly administrations of vincristine, idarubicin and dexamethasone in addition to daily oral thalidomide led to clinical and laboratory remission within 12 weeks.

Hidradenitis suppurativa (HS) is a common inflamma- tory skin disease. Medical treatment is often disappointing and in severe disease surgery remains the therapy of choice. Extensive surgery may be effective but also mutilating. Patients experience a significant reduction in quality of life and the need for new treatment modalities are urgent. In recent years patients with HS have been treated off-label with tumour necrosis factor-α (TNF-α) inhibitors with a varying degrees of effect. We performed a systematic review of papers retrieved from two databases (PubMed and Web of Science) using the following keywords: hidradenitis suppurativa, acne inversa, infliximab, etanercept, and adalimumab. A total of 34 publications were retrieved, describing treatment of 105 patients. Most cases report treatment with infliximab (52/105). A positive treatment outcome was reported in 90/105 cases, with only 7/105 non-responders and 8/105 patients experiencing side-effects. The side-effects were comparable to those seen in other TNF-α inhibitor studies. In the majority of cases the treatment was effective when given as a suppressive therapy, but 15/105 cases were described with long-term remission (>3 months) after the end of therapy. In most publications follow-up was, however, insufficient to allow a systematic exploration of this. TNF-α inhibitors seem to be effective in the treatment of HS. However, several questions remain to be answered through specific studies. This review has also identified a need for more standardized reporting of the outcomes as well as randomized controlled trials in this disease. [ABSTRACT FROM AUTHOR]

Itch is the most frequent symptom in dermatology and has been researched more extensively in recent years. Nevertheless, there are few true epidemiological studies on itch. The aim of this paper is to review the current state of research on the epidemiology of chronic itch in Western and non-Western populations. The electronic databases PubMed, Medline and the Cochrane Library were searched. Conference proceedings and national and international studies were included. It is difficult to compare existing studies due to differing methodology and lack of standardized measures. The symptom of itch is a challenge, not only to clinicians, but also within the structure of regional health systems, and with regards to accessibility to specialized medical doctors in non- Western countries. Published studies show that the symptom of itch is highly prevalent; it should therefore receive adequate attention from physicians and other healthcare providers, including healthcare planners.

The aim of this paper is to report our clinical experience of Sweet's syndrome, a severe dermatological disease which may be extremely important to recognize for the early diagnosis of a neoplastic disorder. Eleven patients affected by Sweet's syndrome, treated at the Department of Dermatology, University of Ferrara, Ferrara, Italy, during 1998 to 2004, were evaluated. A retrospective analysis was performed. Data on age, sex distribution, clinical data, histopathological and immunohistochemical findings and therapy were collected. We observed one patient with idiopathic form, 5 patients affected by the para-inflammatory variant and 5 para-neoplastic cases (with haemoproliferative diseases). The cases with the para-inflammatory form were affected by minor infectious manifestations. Prolonged follow-up is necessary to verify that a case of idiopathic variant is not really a paraneoplastic form. Based on immunohistochemical analysis, we cannot exclude that true histiocytes, immunoreactive for CD68/PGM, infiltrate the dermis in Sweet's syndrome lesions. [ABSTRACT FROM AUTHOR]

Functional itch disorder or psychogenic pruritus is a poorly defined diagnosis. This paper sets out the proposed diagnostic criteria of the French Psychodermatology Group (FPDG). There are three compulsory criteria: localized or generalized pruritus sine materia, chronic pruritus (>6 weeks) and the absence of a somatic cause. Three additional criteria from the following seven items should also be present: a chronological relationship of pruritus with one or several life events that could have psychological repercussions; variations in intensity associated with stress; nocturnal variations; predominance during rest or inaction; associated psychological disorders; pruritus that could be improved by psychotropic drugs; and pruritus that could be improved by psychotherapies.

Since they were first administered to patients with anti-body deficiency disorders over 50 years ago, human intravenous immunoglobulin preparations have been used successfully to treat a rapidly increasing number of auto-immune and inflammatory disorders, among which are a series of cutaneous autoimmune and inflammatory diseases. These include dermatomyositis, Kawasaki's disease, a number of autoimmune bullous diseases, severe adverse drug reactions, and other autoimmune and/or allergic conditions, such as atopic dermatitis. Although only a minority of these indications (dermatomyositis, Kawasaki's disease) are officially registered or based on double-blind, placebo-controlled clinical studies, the observed efficacy and safety profile of currently available intravenous immunoglobulin sometimes makes this a treatment of choice for initiation of therapy or for replacement of more toxic alternatives, such as systemic immunosuppressive medications. The increasing use of intravenous immunoglobulin has been associated with further understanding of its mechanism(s) of action, clinical manipulation and associated side-effects, as well as the introduction of improved or new types of intravenous immunoglobulin. This paper reviews the current knowledge of the mode of action of intravenous immunoglobulin, its reported therapeutic effects in cutaneous disease, its mode of administration and safety profile, and compares the currently available intravenous immunoglobulin preparations.

Conflicts of interest exist in dermatology when professional judgement concerning a primary interest, such as research validity, may be influenced by a secondary interest, such as financial gain from a for-profit organization. Conflict of interest is a condition and not a behaviour, although there is clear evidence that gifts influence behaviour. Little has been written about conflicts of interest in dermatology. This series of papers raises awareness of the subject by exploring it in greater depth from the perspective of a dermatology researcher, an industry researcher, a dermatology journal editor, a health services researcher and a patient representative. Collectively, they illustrate the many ways in which conflicts can pervade the world of dermatology publications and patient support group activities. [ABSTRACT FROM AUTHOR]

An allergy workup is done in many children with atopic dermatitis but its pratical benefit on disease management remains largely unproven. This paper emphasizes the need of a global assessment of the young patient, including compliance to previous treatments and disease severity. Allergy testing should be considered as a second line option, integrated to global management. True food allergy is found in one third of patients with moderate/severe disease, and avoidance diets in such patients help reducing topical corticosteroids consumption. Apart a better delineation of the indication of the tests, there is a need to make allergy workups simplier, and a better standardization of tests is needed. [ABSTRACT FROM AUTHOR]

The aim of this study was to confirm findings that vapour-impermeable panty liners might impair skin climate, and to assess their impact on the skin microflora. Temperature, surface pH and aerobic microflora were measured on vulvar skin of 102 women. The mean skin temperature was 1.1°C higher when using a vapour-impermeable panty liner compared with not using one. Use of panty liners with vapour-permeable back sheets and acidic cores resulted in skin temperature, pH and microflora levels that were very close to those observed in persons not using liners. The temperature, pH and total number of microorganisms were significantly lower for users of vapour-permeable panty liners than for users of vapour-impermeable ones ( p <0.05, p <0.001 and p <0.001, respectively). The microorganism densities were usually higher when using the vapour-impermeable panty liner, but mean differences were minor. The use of panty liners seems not to imply a microbial risk for normal, healthy women. [ABSTRACT FROM AUTHOR]
