The Psychological Burden of Skin Diseases: A Cross-Sectional Multicenter Study among Dermatological Out-Patients in 13 European Countries

The contribution of psychological disorders to the burden of skin disease has been poorly explored, and this is a large-scale study to ascertain the association between depression, anxiety, and suicidal ideation with various dermatological diagnoses. This international multicenter observational cross-sectional study was conducted in 13 European countries. In each dermatology clinic, 250 consecutive adult out-patients were recruited to complete a questionnaire, reporting socio-demographic information, negative life events, and suicidal ideation; depression and anxiety were assessed with the Hospital Anxiety and Depression Scale. A clinical examination was performed. A control group was recruited among hospital employees. There were 4,994 participants––3,635 patients and 1,359 controls. Clinical depression was present in 10.1% patients (controls 4.3%, odds ratio (OR) 2.40 (1.67–3.47)). Clinical anxiety was present in 17.2% (controls 11.1%, OR 2.18 (1.68–2.82)). Suicidal ideation was reported by 12.7% of all patients (controls 8.3%, OR 1.94 (1.33–2.82)). For individual diagnoses, only patients with psoriasis had significant association with suicidal ideation. The association with depression and anxiety was highest for patients with psoriasis, atopic dermatitis, hand eczema, and leg ulcers. These results identify a major additional burden of skin disease and have important clinical implications.

Self-inflicted lesions in dermatology: Terminology and classification - A position paper from the European Society for dermatology and psychiatry (ESDaP)

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; Münchausens 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 patho-logical behaviours, thus it is important for dermatologists to become as familiar as possible with the psychiatric and psychological aspects underlying these lesions.

Angiokeratoma: Decision-making aid for the diagnosis of Fabry disease

Isolated angiokeratomas are common benign cutaneous lesions, generally deemed unworthy of further investigation. In contrast, diffuse angiokeratomas should alert the physician to a possible diagnosis of Fabry disease, a rare X‐linked lysosomal storage disorder, characterized by α‐galactosidase deficiency. Glycosphingolipids accumulate in cells throughout the body resulting in progressive multi‐organ failure. Difficulties are encountered when trying to interpret the significance of angiokeratomas because they may also occur in other lysosomal storage disorders and rarely in an isolated manner in Fabry disease. We present an algorithm for the classification of angiokeratomas which might prove useful for the diagnosis and management of Fabry disease. Assessment of the clinical features and location of the lesions, personal and family history, skin biopsy, dermoscopy and electron microscopy imaging are sequential steps in the diagnostic process. Assessing the deficiency of α‐galactosidase enzyme activity is essential to confirm the diagnosis in males, while mutation analysis is always needed in females. Potentially this algorithm can change the current approach to patients when Fabry disease is suspected, thus improving the diagnostic strategy and management of this disorder. It remains to be decided whether the use of an algorithm might reduce the number of genetic consultations. As evidence has shown the efficacy of enzyme replacement therapy in halting progression of the disease before the onset of irreversible organ damage, it is advisable to aim at an early diagnosis in order to achieve timely initiation of effective treatment with benefits for patients and appropriate use of medical resources.

Perception of disease and doctor-patient relationship experienced by patients with psoriasis. A questionnaire-based study

Background: Many studies have addressed the impact of psoriasis on quality of life, but few studies have investigated patient perception of the disease or the patient-physician relationship. As with most chronic diseases, improvement in the patient-physician relationship may be important in the proper management of patients with psoriasis.Objectives: To assess how psoriasis and its treatments are subjectively experienced by patients as well as patient expectations with regard to the patient-physician relationship.Methods: A discussion agenda for ‘focus group meetings’ was organized by a group of sociologists, psychologists, educators, researchers, and clinicians active in the field of psychodermatology. Four meetings were held in Northern and Central Italy and participants included one moderator and either eight dermatologists or eight patients. Discussions were based on a predefined agenda and included: (i) the psychological representation of psoriasis; (ii) the hetero– and self-perception of the patient; (iii) the patient-physician relationship; and (iv) the development of an educational intervention for dermatologists in order to improve the patient-physician relationship. A questionnaire, based on the information gathered at the focus groups, was administered to 323 patients with moderate to severe chronic plaque psoriasis from 17 dermatology clinics throughout Italy.Results: Three hundred patients completed the questionnaire. Psoriasis elicited anger, annoyance at the inconvenience of the disease, and irritation in approximately 50%of the patients, whilst 38%of patients were unable to describe their emotional state. Aspects of life that were limited by psoriasis included clothing (57%), social interactions (43%), and personal hygiene (31%). The disease was often seen by patients as incomprehensible, incurable, and uncontrollable. More than half of the patients stressed their need to be listened to by the treating physician, and their wish that the physician should use simple language and should improve their psychological skills and interpersonal communication techniques.Conclusions: Dermatologists need to convey to patients with psoriasis the feeling of ‘understanding the disease,’ of hope about its curability, and the ‘perception of control.’ These elements should be taken into account when treating patients and whenever educational interventions are planned.

Acquired Epidermodysplasia Verruciformis: A Comprehensive Review and a Proposal for Treatment

BACKGROUND Epidermodysplasia verruciformis (EV) is a rare genodermatosis characterized by immunologic abnormalities, disseminated human papilloma virus infection, and early development of skin cancers. Acquired forms have been rarely reported and usually occur with immunosuppression. The therapeutic management of the acquired forms is not standardized, and several therapies have been tried, with variable outcomes. OBJECTIVES To provide updated clinical and experimental information on the treatment of acquired EV. METHODS A Medline literature search was performed for relevant Medical Subject Heading terms, reviewing publications on strategies for management of acquired EV. We also report a case successfully treated using a combination of photodynamic therapy and oral retinoids. CONCLUSION Data from the literature show that a standardized approach to this condition is lacking; the combination treatment chosen in our case may be proposed because it led to an excellent clinical outcome and a long‐lasting remission.

Psodisk, a new visual method for assessing the burden of psoriasis on patients

Background  The last decades have witnessed an increasing interest for the psychosocial aspects of chronic skin diseases, such as psoriasis. Nonetheless, systematic assessments of the impact of psoriasis on patients’ lives are rarely done in daily clinical practice. The existing instruments are mostly meant to be completed by patients alone, and rarely comprise a graphical representation of the results.

Why quality of life measurement is important in dermatology clinical practice: An expert-based opinion statement by the EADV Task Force on Quality of Life.

The aim of this study was to describe the many ways in which quality of life (QoL) measurement may potentially be advantageous in routine clinical dermatology practice. Thirteen members of the EADV Task Force on Quality of Life, eight dermatologists, three health psychologists, one epidemiologist and one pharmacoepidemiologist, independently listed all of the ways they thought this may be advantageous. A total of 108 different ways of using QoL information in clinical practice were suggested (median per participant = 8, range = 4–15), and were classified into 20 descriptive groups. These were sorted into the following five categories: inform clinical decisions, clinician–patient communication, awareness of skin disease burden, informing the consultation and clinical service administration. The wide range of potential benefits identified may not only encourage clinicians to use these measures but also highlights many areas requiring evidence to establish the true value of routine use of QoL measures.

Generalized granuloma annulare treated with methylaminolevulinate photodynamic therapy.

Granuloma annulare (GA) is a non-infectious granulomatous dermatosis characterized by annular papules and rarely nodules and plaques, arising on the dorsa of the hands, feet, elbows and knees; it is usually chronic and asymptomatic. The aetiology of GA is unknown, although many hypotheses have been postulated. About 10% of patients affected by GA present the generalized subtype, characterized by a later age of onset and a chronic course with a low tendency to spontaneous resolution. The widespread papular eruption develops on the trunk and upper or lower limbs. Generalized GA is very disfiguring because of the extensive dissemination of the lesions. The response to various treatments, namely topical and intralesional corticosteroids, topical tacrolimus, dapsone, isotretinoin, etretinate or hydroxychloroquine, is usually unsatisfactory. We report 3 cases with long-lasting generalized GA responding to methylaminolevulinate photodynamic therapy.

Dysplastic nevi, cutaneous melanoma, and other skin neoplasms in patients with myotonic dystrophy type 1: A cross-sectional study

BACKGROUND Myotonic dystrophy type 1 (MD1) is reported to be associated with internal malignancies. The association of myotonic dystrophy with cutaneous tumors is not fully understood. OBJECTIVE We sought to explore the total nevi count and the presence of atypical nevi, cutaneous melanoma, and other skin neoplasms in a representative cohort of patients with MD1 and to compare the findings with age- and sex-matched control subjects. METHODS In all, 90 patients with MD1 and 103 age- and sex-matched control subjects were assessed for cutaneous neoplasms by clinical skin and epiluminescence examination (dermoscopy). Where indicated, subsequent excisions were performed. In patients with MD1, leukocyte n(CTG) expansion was measured. RESULTS Patients with MD1 showed significantly higher numbers of nevi, dysplastic nevi, and melanomas despite a significantly greater proportion of the control subjects reporting sunburns. In addition, we found a significantly greater number of pilomatrixoma in patients with MD1. LIMITATIONS Our study is limited by the fact that there is no agreed-upon standardized technique to assess for prior sun exposure. Further research in the association of cutaneous neoplasms and MD1 including vitamin D and molecular biological techniques are also recommended. CONCLUSION MD1 itself may predispose to development of skin tumors.

A Case-control Study on Family Dysfunction in Patients with Alopecia Areata, Psoriasis and Atopic Dermatitis

Family history can provide important information about a patients psychological status, and thus their disease risk. A multicentric case-control study on family dysfunction was performed on 59 patients with psoriasis (63.7%), atopic dermatitis (11.9%) or alopecia areata (25.4%), and 47 patients with minor skin problems (controls), all attending a dermatological clinic or a psychodermatological consultation. The mean age of subjects was 47.7 years in the cases and 48.8 years in the controls. Women represented 53% of cases and 62% of controls. Patients and controls first completed the General Health Questionnaire (GHQ-12) and the Toronto Alexithymia Scale (TAS-20) questionnaire. The overall prevalence of anxiety and/or depression in cases was 43.3% (71.4% in atopic dermatitis). To collect the family history a genogram was built by the interviewer during a semi-structured interview. It can show dysfunction in the family, as it highlights alliances and ruptures, generational repetition of behaviours of dependence or vulnerability, and traumatic events. The mean (± standard deviation) genogram score was 6.7 ± 3.3 in the cases and 3.0 ± 2.4 in the controls (p<0.001). The cases had three times the risk of having moderate family dysfunction compared with controls and 16 times the risk of having a severe family dysfunction. The genogram score was correlated with the severity of the disease as evaluated by the patient. In conclusion, family dysfunction may play an important role in the onset or the exacerbation of psoriasis, alopecia, and atopic dermatitis.
