    Notizen: Immunological and biochemical alterations in atopic dermatitis have been attributed to a deficient conversion of omega-6 fatty acids (i.e. linoleic acid, gamma-linolenic acid, and dihomo-gamma-linolenic acid) to prostaglandin (PG)E1. In patients with atopic dermatitis, however, the formation of PGE1 has not been evaluated so far. We therefore measured plasma concentrations of 15-keto-13.14-dihydro-PGE1 which reflects endogenous PGE1 release, by gas chromatography-mass spectrometry in 31 patients with atopic dermatitis (aged 18-41 years, median 26 years) and in 31 healthy, age and sex-matched control subjects. In order to exclude a metabolic shift from PGE1 to PGE2, we also measured the plasma levels of 15-keto-13, 14-dihydro-PGE2. There was no difference between patients and control subjects with respect to plasma concentrations of 15-keto-13, 14-dihydro.PGE1 (3.9-49.6, median 10.3pg/ml vs. 3.2-80.4, median 8.3pg/ml, P = 0.22), 15-keto-13,14-dihydro-PGE2 (11.6-201.0 median 24.8pg/ml vs. 8.6-201.0.median 19.6 pg/ml, P = 0.10), and the ratio of 15-keto-13,14-dihydro-PGE1 to 15-keto-13.14-dihydro-PGE2 (0.17-1.39, median 0.41 vs.0.2-0.17, median 0.45, P = 0.29). These results indicate that the endogenous formation of both PGE1 and PGE2 is normal in our patients. The results do not confirm the pivotal role that other authors have attributed to a deficient PGE1 formation in the pathogenesis of atopic dermatitis.

    Notizen: Summary Background Frequent bathing leads to a skin barrier damage with various changes in physiological skin parameters. Conversely, ultraviolet (UV) irradiation may improve the impaired skin barrier by reducing inflammatory reactions. Objectives The aim of this study was to investigate the changes of physiological skin parameters during a therapy with 8-methoxypsoralen (8-MOP) bathing and subsequent UVA irradiation. Methods Thirty patients with a skin disease without barrier disruption were treated with daily bathing in a 8-MOP solution (0·0005%) and subsequent UVA irradiation. Multiple physiological skin parameters (transepidermal water loss, skin blood flow, skin colour, sebum content, skin hydration) were measured repeatedly on clinically non-affected skin on the back, forearm and forehead. In addition, patch testing with sodium lauryl sulphate (SLS) (0·5%) was performed on the forearm and on the back. Results We found a moderate but significant disturbance of skin barrier and hydration on the forearm and the back (bathing + irradiation) after increasing dosages of therapy. In addition, SLS testing leads to stronger reactions. Conclusions We conclude that on clinically healthy skin the impairment of skin barrier by frequent bathing cannot be completely compensated by subsequent UVA irradiation. When conducting a treatment with 8-MOP bathing and UVA irradiation a concomitant therapy supporting the recovery of skin barrier, e.g. with moisturizer, should be performed.

    Notizen: Summary Background Keratitis–ichthyosis–deafness (KID) syndrome is a debilitating ectodermal dysplasia that predisposes patients to develop squamous cell carcinomas in addition to leading to profound sensory deafness and erythrokeratoderma. We recently demonstrated that KID can be caused by a specific missense mutation in connexin 26 (GJB2). Another syndrome, called hystrix-like ichthyosis–deafnesss (HID) syndrome, strongly resembles the KID syndrome. These disorders are distinguished mainly on the basis of electron microscopic findings. We hypothesized that KID and HID syndromes may be genetically related. Objective To demonstrate by mutation analysis that HID and KID syndromes are genetically indistinguishable. Methods DNA was extracted from paraffin-embedded tissue samples of the first HID syndrome patient described in the literature. Since the KID syndrome mutation abolishes an AspI restriction site, we were able to screen the patient's DNA by polymerase chain reaction and subsequent restriction enzyme analysis. Results Restriction analysis of the connexin 26 gene in HID syndrome demonstrated the presence of the KID syndrome mutation that we previously described. This result was confirmed by direct DNA sequencing. Conclusions We show that KID and HID syndromes are identical at the molecular level and confirm the clinical impression that these syndromes are one and the same. That previous clinical reports made a distinction may be a consequence of sampling artefacts; alternatively, genetic background effects such as the presence of concurrent mutations in other skin-expressed genes may modify the phenotype.

    Notizen: Background  After using cosmetics, Japanese women frequently complain about sensitive, stinging skin. We wondered whether Japanese women's skin is more sensitive than that of Caucasians.Objectives  To examine possible racial differences of skin irritation and subjective sensations.Methods  We performed patch testing on the forearm with sodium lauryl sulphate (SLS) at different concentrations (0·25%, 0·5%) and 24-h exposure time. Skin reaction was evaluated by measurement of transepidermal water loss (TEWL), stratum corneum hydration, sebum secretion, laser Doppler flowmetry (LD), content of melanin and erythema. During a stinging test with 10% lactic acid (applied to one side of the cheeks) the subjects were asked to describe the present intensity of any sensation. We used a Chromameter to measure skin colour before and after application of lactic acid. This study was performed in Marburg, Germany, with healthy Japanese and German women living in Marburg.Results  After SLS testing, we found no significant differences of the barrier function in the stratum corneum, but we found significant subjective sensory differences between Japanese and German women.Conclusions  Japanese women may complain about stronger sensations reflecting a different cultural behaviour rather than measurable differences in skin physiology; however, a faster penetration of SLS in Japanese cannot be excluded.

    Notizen: We describe a 13-year-old girl with multiple pigmented nodules and plaques arranged in a cluster in the right lumbar region, which had developed since infancy.Eleven of 15 lesions which were examined histologically were found to be Spitz naevi. The remaining four lesions were compound naevocellular naevi, and two of them showed focal dysplasia. Eight Spitz naevi were investigated immunohistologically with monoclonal antibodies against HLA-antigens and malignancy-associated melanocytic antigens which are rarely present in common naevi. Naevus cells in all lesions expressed HLA-ABC antigens, but lacked HLA-DR antigens in seven of the eight lesions. All naevi were positive for ‘constitutive’ (KG-6-56) and ‘early’ (K-i-2) markers of nacvomelanocytic cells. In five of the eight Spitz naevi, at least one of the three malignancy-associated melanocytic antigens PAL-M1, A-1-43 and A-10-33 was found.The expression of malignancy-associated antigens in multiple agminate Spitz naevi is at variance with their benign clinical course.

    Notizen: The therapeutic effect of thalidomide in chronic discoid lupus erythematosus (CDLE) was studied in sixty patients who were followed up for 2 years. In fifty-four patients (90%) a complete or marked regression of the disease was observed, but when the thalidomide was stopped, thirty out of forty-one (71%) patients relapsed. Patients undergoing a second course of thalidomide treatment again responded well. Nine of the patients in whom the disease recurred after successful treatment with thalidomide and who had been unresponsive to intermittent treatment with antimalarials, showed a good response to a second or third course with thalidomide. Mild side-effects were common and 25% of patients complained of slight to moderate polyneuritic symptoms. Since electroneurological examinations had not been performed before the thalidomide therapy, the frequency of neurological side-effects cannot be accurately calculated but we recommend neurological examinations before and periodically during thalidomide treatment.Thalidomide is a very effective drug in CDLE, but in most cases it exerts its effect only whilst treatment is continued. Its use should be restricted to patients resistant to topical steroids and systemic antimalarials.

    Notizen: Summary Two patients with an unusual association of extensive cutis marmorata telangiectatica congenita and aberrant mongolian spots are reported. We believe that such association is best explained as a phenomenon of non-allelic twin spotting. We found only one previous similar case in a textbook, and we support the classification of this condition as phacomatosis pigmentovascularis type V.
