Modern psychodermatology relies on the bio-psycho-social disease model in psychosomatics, according to which biological, psychological and social factors (on various levels, from molecules to the biosphere) play a major role in the disease pathogenesis through complex, non-linear interactions over the entire disease course. It is nowadays experimentally proven that "emotions get into the skin". Recent research shows close anatomical, physiological and functional connections between skin and nervous system, already known to be ontogenetically related. These connections are reflected in many skin diseases where psychological and somatic etiological factors are closely intertwined. A holistic approach by the physician should do justice to this interdependence; biological, psychological and social factors should be adequately taken into account when taking anamnesis, making a diagnosis and choosing a therapy. The "visibility" of the skin organ bestows dermatology a special position among the various other clinical subjects, and renders a holistic, psychosomatic approach to the patient that is particularly important. The life course belongs also to modern psychodermatological approaches. Based on the modern psychodermatology concept, other corresponding sub-areas such as psychogastroenterology, psychocardiology etc. have emerged. After the theoretical part of this article, some selected skin diseases are discussed in more detail from the psychosomatic point of view., (© 2020 The Authors.

Objective: The objective of this study was to prove training-specific effects in children with atopic dermatitis (AD) and their parents concerning coping with the disease after their participation in a training program. In the 1-year follow-up, the changes in the training group were compared to the changes in a waiting control group while controlling the effects of the changes in severity scores., Methods: One hundred eighty-five children aged 8-12 years and their parents participated in the study. Complete data sets at the 1-year follow-up were available for 185 parent-child pairs (102 training group; 83 waiting control group). In addition to the severity of the AD [measured with the Scoring Atopic Dermatitis (SCORAD)], data on children's itching-scratching cognitions and coping behavior and on parents handling their affected children were used in the analysis. To study whether the intervention group experienced an additional psychological benefit, which is not due to the SCORAD values, analyses of covariance with repeated measures with standardized residual change scores of the SCORAD as covariate were calculated., Results: The intervention group showed greater improvement in children's coping behavior and in parents' handling their affected children. Additional effects of the training program not due to somatic improvement could be seen in the scales of itching-scratching cognitions and in three of four scales on parents dealing with their affected children., Conclusion: The training program, which was tested in the German Atopic Dermatitis Intervention Study, had effects on almost all explored psychological variables. Therefore, additional psychological benefit in the training group does not only depend on the greater improvement of SCORAD values in this group., (Copyright 2010 Elsevier Inc. All rights reserved.)

Objectives: The Clinic for Psychosomatic Medicine and Psychotherapy at the University Giessen, Germany, offers short-term (STT) and long-term inpatient therapy (LTT)., Methods: In a prospective, 3-year follow-up study, we examined therapeutic indication, short- and long-term results, outcome predictors, and the utilization of aftercare for both settings., Results: STT patients were more frequently acutely ill, suffered from stronger symptomatic manifestations, and were more frequently employed. LTT patients had a greater rate of chronic psychosomatic disorders, personality disorders and somatic comorbidity. In both settings, distress strongly declined during inpatient therapy and remained stable for 3 years. Negative predictors of outcome were infantile object relation patterns and interpersonal problems. We found no differences between STT and LTT patients in terms of the utilization of aftercare., Conclusion: Duration of psychosomatic inpatient treatment should be differentiated according to the chronicity and nature of the disorder.

Psychosomatic dermatology deals with skin disorders that are substantially influenced by psychosocial causes, sequelae or circumstances or in which these are important in the selection of therapy for the particular patient. In this context, skin diseases have been recognized in a biopsychosocial model for holistic medicine. In a wider sense, psychosomatic dermatology embraces every aspect of intra- and interpersonal problems relating to skin disorders and psychosomatic trigger mechanisms and/or ways of coping with skin disorders. A distinction is made between primarily psychic conflicts, psychosomatic diseases and somatopsychic aspects. Approaches to treatment take account of the doctor (doctor's-assistant)-patient relationship, compliance factors, the dermatosis patient's quality of life and the psychosocial health of the dermatologist, and also steps that can be implemented in the context of the practice management and basic psychosomatic treatment including referral for special psychotherapy.

In dermatology, primary emotional disorders with cutaneous manifestations, secondary emotional disorders caused by dermatoses and multifactorial diseases are possible indications for the use of psychopharmaceuticals. Neuroleptics (anti-psychotics) are usually used in psychiatric illnesses, while antidepressants are foremost in treating depression as well as obsessive-compulsive, anxiety and panic disorders. Minor tranquilizers may be used symptomatically. To define the indications for mid- and long-term treatment with psychopharmaceuticals, the unequivocal diagnosis of the main and secondary psychiatric symptoms as well as the primary target symptoms must be designated. At the start of therapy planning, any possible desired and undesired side effects must be taken into account, such as stimulation, sedation, anticholinergic side effects or weight gain. The main antidepressants are the well-tolerated selective serotonin reuptake inhibitors (SSRI) such as sertraline, fluoxetine or citalopram. A clear long-term plan and how to monitor it must be discussed with patient carefully because of the need for individual dose titration and the late onset of action of many of these medications. Good results can be achieved in dermatologic patients requiring psychopharmaceuticals if the indications are carefully assessed and the therapy logically structured.

Objective: Psychological side effects of the therapy with interferon-alpha (IFN-alpha) have frequently been reported. The symptomatology varies, although there seems to be a predominance of depressive complaints. Mediating somatopsychological vs. psychosomatic pathways remain unknown so far., Patient: We describe the case of a 26-year old female inpatient suffering from hepatitis C infection. During medical treatment with interferon-alpha, a transfer to a psychosomatic unit became necessary due to increasing agitation, somatization and a lacking response to psychopharmacological medication., Results: After the discontinuation of IFN-alpha-treatment, the patient's gradual emotional stabilization could be attained. In psychotherapy, inner conflicts as well as fears about possible side effects of the medication were worked through. After discharge, parallel to an ambulatory psychotherapy, the IFN-alpha medication was readministered and completed successfully., Conclusions: As long as aetiology and mechanisms of psychic side effects of IFN-alpha-treatment remain unclear, ward-based integrative psychosomatic psychotherapy can be supportive and enlightening with regard to psychosocial factors of influence on the IFN-alpha-induced side effects.

Introduction: The prevalences and differences of biopsychosocial disorders were investigated in the dermatologic clinics of Erfurt and Giessen, where a liaison-therapy model has been established. Different dermatological diseases were compared by a variety of psychological tests, and patients with the same diagnosis were compared between the two clinics., Patients and Methods: We examined 406 patients for psychosomatic problems with diagnostic interviews and psychometric tests. The coping of skin disease questionnaire (CSD) and the Symptom Checklist (SCL-90R) served as diagnostic measures. Between 1995-2000, 71 patients were seen in Erfurt and 335 in Giessen. The distribution of skin diseases and the psychosomatic disorders are shown by ICD-10 diagnoses., Results: The comparison of an East and a West German city showed no significant differences in the whole group or the parallel groups using the CSD and SCL-90R. There was only a tendency to a greater reduction of quality of life in Erfurt. Patients with glossodynia evaluated themselves in all psychometric tests as very "normal". By contrast, patients suffering from alopecia and acne felt very helpless and seemed to have a need of greater psychosocial care., Conclusions: The biopsychosocial characteristics of the patients treated in the dermato-psychosomatic units in Erfurt and Giessen show no significant differences. Patients with diseases such as alopecia and acne are underestimated in regard to the need for additional psychosocial care. The liaison therapy model is an effective approach to diagnose psychosomatic-dermatological disorders and decide if further psychosomatic treatment is indicated.

Intolerance reaction of the skin refers to multiple reaction patterns, including toxic, allergic, pseudo-allergic and even psychiatric mechanisms. In our case, a patient was diagnosed for years as having "multiple allergies", but except for a documented contact allergy to a local anesthetic, her underlying disease was panic disorder with multiple phobias. Using this case study with one year follow-up, hypotheses are discussed about effective psychotherapy in patients with intolerance reactions of the skin. Differential indications are explored with reference to the latest investigative results in psychoneuroimmunology. In this patient, psychotherapy helped the phobias and eliminated her conviction that she had multiple allergies. In addition, the positive pre-therapy allergy testing was not reproducible. The dermatologist should not expect such patients to present with phobias, because they frequently shift their phobic anxiety into the fear of allergic reactions to escape from the label of having psychiatric disease. Such patients should receive psychotherapy if they begin to generalize their avoidance behavior and limit their social contacts.

The psychic-dynamic factors underlying the hypochondriac disorder involving an obsessive preoccupation with physical attractiveness (dysmorphophobia) and the treatment possibilities for some manifestations of this syndrome have been examined. This psychosomatic illness frequently leads to the taking of finasteride, a medication that halts the balding process in cases of androgenetic alopecia or even stimulates renewed hair growth. The nosological demarcation of the disorder requires the differential diagnosis of depressive, hypochondriac and delusionary disorders. The psychodynamics involved, as deduced from 2 case studies, takes the form of an expansion of the patients' reductionist perspective, characterized by an emphasis on external types extending to a psychogenetic attitude with regression into narcissistic fixation. The authors seek eternal youth which is a "leitmotif' of the disorder, and they apply the term "Dorian Gray Syndrome" after Oscar Wilde's novel. The treatment recommended is a course of intensive psychotherapy; often the topic of "life-style medication" must be introduced before the specific narcissistic conflicts behind the current symptoms can be treated.

Background and Objective: A questionnaire study of German dermatological clinics was designed to show the situation and development of psychosomatic dermatology 10 years after a similar study., Patients/methods: A questionnaire was sent to 170 dermatological clinics. 76 were send back; 69 of them (40.6%) were evaluable. The questionnaires were mostly answered by the heads of the dermatological clinics (38/69 = 55.1%)., Results: Nearly 85% of the dermatological clinics answered that they take psychosomatic aspects into consideration in the therapy. 5.1% of the dermatologists working in clinics have additional psychotherapeutic certification. The improvement of coping behaviour seems to be the main goal of psychosomatic interventions. The importance of psychic factors increased in the last 10 years in comparison to a former study in regard to most of the dermatological diseases., Conclusions: Psychosomatic aspects seem to be an obligatory part of inpatient dermatological therapy. The frequency of some diseases was underestimated in comparison with results from literature.

Based on the current literature, the paper gives an overview of the state of knowledge in psychosomatic dermatology. The authors propose the following classification: (1.) Dermatologic problems as a consequence of psychic disorders (e.g. factitious disorder, trichotillomania, dysmorphophobia, delusions of parasitosis etc.); (2.) Multifactorial dermatologic disorders, which can be substantially influenced by psychological factors (e.g. atopic dermatitis, psoriasis, chronic urticaria etc.); (3.) Psychic disorders developing as a consequence of disfiguring or life-threatening dermatoses (e.g. adjustment disorder, depressive disorder, anxiety disorder); (4.) Comorbidity with other psychiatric disorders. Psychosomatic dermatology developed from an anecdotal initial stage to more systematic research with larger numbers of patients, employing control groups and psychometric instruments. During the last decade, research focused on psychophysiological and psychoneuroimmunological mechanisms which influence dermatologic disorders. This course of development and the current state of knowledge are presented for atopic dermatitis and psoriasis.

The aim was to determine the relationship between mercury content of resting and stimulated saliva, and blood and urine. Eighty subjects participated; 40 of them attributed their self-reported complaints to dental amalgam (patients), the others were matched with respect to age, sex and amalgam restorations (controls). Serum, 24-h urine, resting and chewing stimulated saliva were analyzed for mercury using the ASS-technique. Quality, number, surfaces and total area of amalgam fillings were recorded clinically and using study models. Median (range) mercury levels in serum were 0.67 (0.1-1.52) microgram/l for patients and 0.60 (0.1-1.3) for controls. In urine levels were found to be 0.77 (0.11-5.16) and 0.94 (0.17-3.01) microgram/g creatinine respectively. No significant differences were found between the groups. Resting saliva contained 2.97 (0.10-45.46) micrograms/l in patients and 3.69 (0.34-55.41) in controls (not significant). Chewing mobilized an additional amount of 16.78 (-6.97 to 149.78) micrograms/l in patients and 49.49 (-1.36 to 504.63) in controls (P < or = 0.01). Only a weak correlation was found between mobilized mercury in saliva and serum (r = 0.27; P < or = 0.05) or urine (r = 0.47; P < or = 0.001). For resting saliva the respective values were r = 0.45 (P < or = 0.001) and r = 0.60 (P < or = 0.001). Saliva testing is not an appropriate measure for estimating the mercury burden derived from dental amalgam.

The effectiveness of concurrent psychotherapeutic treatment for various skin diseases can be regarded as sufficiently validated. Contributions on in-patient treatment concepts are rare, and there are up to now no reports on methods integrating psychotherapeutic treatment approaches. Our concept of a 4-week short-term psychotherapy-starting from a conflict hypothesis in the complaint intensifying, acute situation-includes the bimodal work on both understanding and practice oriented treatment focus. By means of 2 case studies with 1-year-follow-up, insight is given into the treatment approach from which effective factors of psychotherapeutic treatment were tentatively in with patients with skin diseases.

25 male patients suffering from acne vulgaris were examined by means of endocrinological, morphological, and 5 psychometric procedures in order to check the correlations and interactions between the psychological and dermatological aspects of the disease. In comparison with a control group, the acne patients did not show any striking endocrinological abnormalities; we found no correlation between the extensiveness of the lesions and the level of DHEA sulphate. All the psychological tests yielded results deviating from those achieved by the representative controls, but they were comparable with those of other patients suffering from psychosomatic diseases. The individual feeling of being "disfigured" found its expression in self-consciousness, lack of trust in his/her own body, as well as the clinically relevant difference between his/her conception of self and the ideal of self. During times of enhanced psychosocial strains subjectively assumed by the patients, the lesions increased and the patients were disturbed in social interaction and communication. Surprisingly, we did not find any correlation between the clinical status and significant psychometric findings. Our results show that in acne vulgaris, the individual experience of wanting physical attractiveness, associated with a predominantly neurotic depressive personal structure, may play a central part in a disturbed process of interaction with the environment and suggest the influence of psychic factors in the pathogenesis of acne vulgaris.

The present study was performed to investigate whether patients with atopic dermatitis differ as a group from controls on psychological measures of mood and personality or whether psychologically deviant and normal patient subgroups can be distinguished. Furthermore, we were interested in what clinical characteristics might co-vary with psychological disability in patients with atopic dermatitis. In all, 93 patients filled in a standardized mood scale (Hamburg-Erlanger-Stimmungsbarometer) and a personality scale (Kurztest zur Erfassung der Persönlichkeitsstruktur). Compared with matched controls, patients described themselves as being more anxious, more aroused, more depressed and less energetic, and they reached higher neuroticism scores. A cluster analysis identified four patient subgroups. Only one of the subgroups (n = 17) was psychologically disabled according to the questionnaire scores. In contrast to a psychologically stabile patient group, the psychologically disabled patients showed an earlier age of onset of dermatitis, but less intense itching and scratching. They reported more somatic complaints and a higher level of familial stress, were more dissatisfied with their life situation and work, had fewer friends and experienced more losses of significant others. Furthermore, they more frequently rated their disorder as being determined by psychological factors and were more intelligent. Thus, the questionnaires identified a subgroup of patients who may need psychotherapeutic interventions.
