    Notizen: A 51-year-old white male suffering from metastatic malignant melanoma of the skin presented with lymph node metastases and paraneoplastic retinopathy 4 years after resection of the primary tumour. There were no cerebral metastases. Ocular symptoms consisting of night blindness and sensations of ‘shimmering lights’ persisted after total resection of the inguinal lymph node metastases and administration of dacarbazine and prednisone. Perimetry of both eyes was abnormal with concentric restriction. Electroretinography showed significantly reduced amplitudes in both eyes. Only 11 patients with melanoma-associated retinopathy (MAR) have been described. High titres of autoantibodies against whole retina extract were detected by enzyme-linked immunosorbent assay (ELISA) reactions. Indirect immunohistochemistry showed strong autoantibody activity against retinal bipolar cells.

    Notizen: Schäfer T, Ring J. Epidemiology of allergic diseases.The escalation of allergic diseases (hay fever, asthma, atopic eczema) over recent decades has been linked to an increase in environmental pollutants. The prevalence of hay fever is associated with genetic predisposition, and some reports show an association with urban areas, socioeconomic status, and combined high allergen and automobile exhaust exposure. In asthma, there is also some evidence for geographical variations in prevalence; exercise challenge tests prove positive more often in urban areas than in rural areas. Although genetic predisposition is the strongest single risk factor for atopic eczema, air pollutants may aggravate the condition by acting as unspecific irritants and immunomodulators, leading to increased immunoglobulin E expression. In a study of 678 pre-school children, the influence of maternal smoking habits on individual measures of atopy revealed a positive association between smoking during pregnancynactation, and a positive history of atopic eczema. An East-West German comparative study examining different types and levels of air pollution, i.e. sulphurous (industrial; East) and oxidising (urban; West), showed that the prevalence of atopic eczema was greatest in East Germany. When various direct and indirect parameters of air pollution exposure were measured, the greatest association with atopic eczema was found with NOx exposure (indoor use of gas without a cooker hood), and close proximity to roads with heavy traffic. The increased prevalence of atopic eczema cannot be explained by changes in study methodology over time, or conventional risk factors alone; environmental risk factors may be an important contributing factor.

    Experiences with the severity scoring of atopic dermatitis in a population of German pre-school children (1997)

    Notizen: Severity scoring of atopic dermatitis (SCORAD) was introduced as a standard tool but has not been used in a population-based epidemiological study; the objective of the present study was to determine the practicability of this instrument in this setting. We assessed the distribution of the severity of atopic eczema in the community and investigated differences between east and west Germany. A factor analysis was then carried out to characterize the variables of this scoring system and to analyse possible relationships within them. A multicentre cross-sectional study was carried out in five east German and two west German locations in 1994; pre-school children (5–6 years old) were investigated and cases of atopic eczema identified by a dermatological examination. The SCORAD was used to determine the severity of atopic eczema and the results assessed using analysis of variance and principal component analysis (varimax rotation). In all, 1511 (76·2%) of the children originally contacted participated and 11·3% were diagnosed with atopic eczema at the time of examination. The median severity score was 21·4 (interquartile range 13·5) and there was a tendency to higher scores in west Germany for the mean overall score, the intensity score and the extent. ‘Erythema’ (1·30 vs. 1·06; P= 0·006) and ‘excoriation’ (0·77 vs. 0·36; P= 0·002) were significantly more prominent in children with eczema from west Germany (adjusted for observer). Interobserver variabilities of the SCORAD parameters were calculated, adjusted for location and were in accordance with earlier findings. Principal component analysis identified three independent factors accounting for 54·1% of the total variance. A severity factor, characterized by ‘extent’, ‘lichenification’, ‘excoriation’ and ‘pruritus’, was separated from a factor with an acute eczema-type profile (‘erythema’, ‘oedema’, ‘oozing’) and a factor whose major characteristics were ‘extent’, ‘dryness’, and ‘sleep loss’. We conclude that atopic eczema is frequent in pre-school children. The SCORAD proved to be readily applicable and useful in epidemiological studies, but further validation is needed.

    Skin testing of the pruritogenic activity of histamine and cytokines (interleukin-2 and tumour necrosis factor-α) at the dermal–epidermal junction (1997)

    Notizen: Cytokines have been proposed as histamine-independent itch mediators. To investigate this hypothesis, single doses of interleukin-2 (IL-2, 10MU/mL) and tumour necrosis factor α (TNF-α, 10 μg/mL) were delivered to the epidermis of 10 healthy volunteers with a controlled skin-prick model; 1% histamine and solvent controls were included in a double-blind, randomized crossover design. Itch ratings (computerized visual analogue scale) were obtained every 20s for 15 min and cutaneous reactions (weal, flare and temperature) were measured. Reactions were also recorded after 2, 24 and 48 h. The mean itch ratings were: histamine 35·5, IL-2 3·3 (both P〈0·01 compared with control), TNF-α 1.6 and solvent control 1.75 (not significant). Weal and flare occurred only with histamine. In two volunteers, an inflammatory papule with transient pruritus developed 12–18 h after applying IL-2. In conclusion, IL-2 showed a rapid, low pruritogenic effect, which may be followed by an inflammatory response. TNF-α induced no itching in this setting. Skin-prick testing with appropriate doses of potential pruritogens provides a safe and sensitive model for further chemoreceptor studies.

    Notizen: After contact with grass pollen, seasonal exacerbations of eczematous skin lesions have been described in a subgroup of patients with atopic eczema (AE). Epicutaneous patch testing with aeroallergens (atopy patch test, APT) has been used to investigate these patients. We performed comparative APT in 79 patients with AE and 20 control subjects (14 non-atopic volunteers and six patients with grass pollen allergic rhinoconjunctivitis). Subjects were tested with grass pollen allergen extract in petrolatum and with unprocessed native dry pollen of Dactylis glomerata. Results after 48 h were compared with the patient's history, corresponding skin prick test and specific IgE. Fifteen of the 79 AE patients showed clear-cut eczematous reactions to unprocessed D. glomerata pollen; 14 of these had an elevated serum IgE to D. glomerata and 13 had a positive skin prick test. Twenty patients had a positive APT reaction to grass pollen allergen extract, including 12 of the D. glomerata reactive subjects (P 〈 0.001). Positive patch test reactions to D. glomerata were seen in 66.7% of cases with and 10.5% of patients without a predictive history of exacerbations during the pollen season. For the standardized extract, these percentages were 75% vs. 16.4% (P 〈 0.001). No side-effects were observed. Control subjects showed no positive reactions. We conclude that grass pollen preparations may be used to investigate trigger factors for eczematous skin lesions in a subgroup of patients with AE.

    Notizen: During rush venom immunotherapy (VIT), about 65% of patients develop large local reactions (LLR) at the application site that last for at least 24 h. However, LLR subside during long-term treatment. To learn more about the provenance of infiltrating cells in late, local skin reactions during VIT, we analyzed the skin infiltrates of 23 Hymenoptera venom (HV)-allergic patients. Punch biopsies were obtained 24 h after s.c. injection of HV allergens from 23 HV-allergic patients and five nonallergic controls. Seven patients did not show LLR at the beginning of VIT. Ten patients had LLR when the dose of HV allergens was increased. Six patients showed reduced LLR after long-term treatment. Immunoenzymatic labeling of the cryostat sections with a panel of monoclonal antibodies was performed by the APAAP method. S.c. application of HV allergens induced a perivascular and periadnexial cutaneous mononuclear cell infiltrate consisting mainly of CD4+, CD45RO+, and HLA-DR+ cells in patients without clinically apparent LLR. In contrast, LLR were associated with a significant increase in total cells, CD4+ cells, CD8+ cells, CD11c+ cells, EG2+ cells, NP57+cells, HLA-DR+ cells, CD45RO+ cells, CD45RA+ cells, CD23+ cells, and CD25+ cells (P 〈 0.001). Decreased LLR after long-term VIT was correlated with a significantly reduced recruitment of CD4+ cells, EG2+ cells, and CD23+ cells as compared to LLR in the course of dose increases (P〈0.05), whereas the number of CD8+ cells, CD11c+ cells, NP57+ cells, and CD25+ cells remained high. Our data suggest that s.c. injections of HV allergens attract CD4+ helper T cells, of both the naive (CD45RA+) and memory (CD45RO+) phenotypes, to the allergen application site. LLR represent delayed allergic rather than toxic reactions to HV components and might be relevant to the development of clinical protection during VIT.

    Beschreibung / Inhaltsverzeichnis: Summary In dermatological practice, itch is the leading symptom of many skin diseases with a variety of psychophysiological aspects. However, a complete inventory for the qualitative evaluation of these central nervous factors is missing, whereas in pain research, the McGill Pain Questionnaire is well established for this purpose. Thus, therapeutic effects of antipruritic agents are only incompletely described by visual analog scales or parameters of skin physiology. Here, a questionnaire modified in analogy to the McGill pain questionnaire is presented, developed in cooperation between dermatologists and neurophysiologists.
    Notizen: Zusammenfassung Juckreiz stellt in der dermatologischen Praxis ein führendes Symptom mit vielen psychophysiologischen Facetten dar. Dennoch fehlt – im Vergleich zur Schmerzforschung, in der der McGill Pain Questionnaire inzwischen eine wichtige Routinefunktion hat – ein vollständiges Inventar zur qualitativen Erfassung dieser zentralnervösen Aspekte. So sind z.B. therapeutische Wirkungen nur unvollständig an Visual-analog-Skalen oder hautphysiologischen Parametern validierbar. In Ergänzung zu diesen Verfahren wird hier ein multidimensionaler Fragebogen als modifiziertes Analogon zum McGill Questionnaire vorgestellt, der in Zusammenarbeit von Hautklinik und Neurophysiologie entwickelt wurde.
