    Notizen: We describe a 65-year-old woman who had had wart-like lesions on the hands, lower arms and forehead for about 45 years. She had already had several basal cell carcinomas excised. Histological study, electron microscopy and in situ hybridization [human papilloma virus (HPV)-types 5/8/12/14/19–23/25/36] of skin biopsies confirmed a diagnosis of epidermodysplasia verruciformis (EV). Photodynamic therapy (PDT) was performed using a 20% 5-aminolaevulinic acid ointment applied for 6 h to the lesions and irradiating using an incoherent light source (λ = 580–740 nm, 160 mW/cm2, 160 J/cm2). Following PDT, blistering and crusting of the lesions occurred, but these healed completely within 2–3 weeks without scarring, and the cosmetic result was excellent. Six months after PDT a skin biopsy was taken. In situ hybridization was positive for HPV type 8 in skin which was clinically and histologically normal. Twelve months after PDT a few lesions had recurred on the hands. Although permanent cure of EV cannot be achieved by any therapy at present and single lesions continue to appear in this patient, topical PDT might result in better control of HPV-induced lesions.

    Notizen: Objectives To assess the importance of the patient’s age at the start of treatment of a port-wine stain (PWS) with the flashlamp-pumped pulsed dye laser (FPDL). Background FDPL treatment is safe and effective for PWSs, with a low risk of scarring and pigmentary changes. The degree of clearing of the lesion is, however, unpredictable, and the ideal time to start treatment has not yet been agreed. Patients/methods By means of a questionnaire, we investigated the frequency of recurrence in PWS in 147 patients after completion of treatment with the FPDL. Results In 24 patients (16·3%), partial redarkening of their PWS was observed. The patients who had a recurrence were not different from the group who did not regarding the colour of the PWS , the response to previous treatment or the frequency of side-effects. Children under 10 years of age did not show any PWS recurrence, at least in our group of patients. Conclusions The age at the beginning of treatment may have an influence on the recurrence rate.

    Notizen: Metoprolol, a widely prescribed β-adrenergic receptor blocker, has occasionally been associated with a diversity of cutaneous reactions. We present a 79-year-old male patient with erosive lichen planus (LP) on the feet and hands who was successfully treated with topical tacrolimus. Six months after the lesions had been cured the patient received the β-receptor blocker metoprolol for the treatment of hypertonus. Within only 2 weeks of metoprolol intake the erosive lesions on the palms and feet recurred. After discontinuation of the drug and repetitive topical treatment with tacrolimus a complete remission of the lesions could be achieved. The recurrence of erosive LP probably secondary to metoprolol and the therapeutic success of topical tacrolimus in the treatment of LP are discussed.

    Notizen: Progress in the understanding of psoriasis as a T-cell mediated inflammatory disease has led to the development of new immunomodulatory therapies. Currently the main focus is on the so-called biologics (or biological agents), including fusion proteins, monoclonal antibodies, cytokines and selective receptors. They mainly target single steps in the complex cascade of humoral and cellular inflammatory immunomechanisms that finally lead to the accelerated growth of epidermal and vascular cells in the psoriatic lesions. The most promising and advanced biological agents are discussed along with their influence on the critical pathophysiological steps in psoriasis, including depletion of T cells, blockade of initial T-cell activation and T-cell receptor (TCR) stimulation, blockade of costimulatory signals and T-cell proliferative signals as well as restoration of the T helper type 1 (Th1)/Th2 balance by diminishing type 1 cytokines and administration of type 2 cytokines. In addition to the biological agents, further development of ‘classical’ dermatological therapies, such as retinoids, or the discovery of new indications for non-dermatological agents contribute to the novel pharmacological approaches in the treatment of psoriasis.

    Notizen: The synchronous application of narrowband UVB phototherapy with 311 nm lamps (Philips TL-01) and bathing in Dead Sea salt solution was evaluated in a multicentre trial (n = 60) in outpatients suffering from psoriasis vulgaris. The study design consisted of an initial therapy phase of up to 35 treatments (three to five times a week) followed by maintenance therapy with up to 35 further applications (once or twice a week). Evaluation was performed separately for patients in according-to-protocol (ATP) (n = 280) and intention-to-treat (ITT) (n = 692) groups. An overall significant improvement of the Psoriasis Area and Severity Index (PASI) score (P 〈 0·05) could be shown for both groups during initial therapy with 71·4% improvement for ATP and 61% for ITT patients. The mean PASI for ATP (values for ITT in parentheses) was 17·7 (18·6) at baseline, 9·5 (10·7) after 20 applications and 5·2 (7·4) at the end of initial therapy. On average, ATP patients received 3·9 (3·5) applications per week with a cumulative irradiation dose of 19·5 J cm−2 (16·2 J cm−2). The most frequent side-effect was erythema, observed in 8·7% of the patients. Subjective evaluation of the therapy by the patients (n = 168) was excellent. Seventy-nine per cent of patients preferred the new treatment strategy in comparison with other previous therapies and 88% regarded this therapy as pleasant and comfortable. In conclusion, we could demonstrate a significant effect of therapy in both the ATP and the ITT groups for this new treatment system which imitates, as far as possible, the Dead Sea climatic conditions, with no severe side-effects and a high acceptance by the patients.

    Notizen: Wells’ syndrome, or eosinophilic cellulitis, is characterized by recurrent cutaneous swellings which resemble acute bacterial cellulitis, and by distinctive histopathological changes. Skin lesions show dermal eosinophilic infiltration and the characteristic‘flame figures, which are composed of eosinophil major protein deposited on collagen bundles. The idiopathic hypereosinophilic syndrome is a multisystem disease with a high mortality rate. It is characterized by peripheral blood eosinophilia and eosinophilic infiltration of many organs, including the skin. The most common skin lesions are pruritic maculopapules and nodules over the trunk and limbs, with urticaria and angio-oedema. In contrast to Wells’ syndrome, the pathology of these skin lesions is non-specific with variable eosinophil infiltration. We report overlapping clinical and histopathological findings characteristic of both syndromes in one patient. Our data favour the hypothesis that both syndromes represent an abnormal eosinophilic response to a variety of underlying diseases or causative agents and thus are different expressions of one disease entity linked to theimmunobiology of eosinophils.

    Notizen: Abstract:  Currently, the scale and consistency of changes of gene expression profiles in models of melanoma progression are largely unknown. Therefore, we investigated siblings of cell lines of malignant melanomas (MM), which have been selected by nude mouse passages for (a) increased tumorigenicity (local ECM-independent growth), (b) metastatic potential, or (c) selected for increased invasiveness using the Boyden chamber. cDNA array analysis surveying more than 27.000 transcripts per cell line showed that 1.5–2.8% of all detectable transcripts were consistently differentially regulated during the selection processes in those models. Using array analysis, we identified 33 individual transcripts that exhibited significant differential hybridization paralleling the increased aggressiveness of the selected progeny. Because some of those genes could play a significant functional role in the progression of MM, we additionally proved their regulative pattern using Northern blotting. Among others, progressive overexpression of osteonectin/SPARC, a molecule that is known to be involved in tissue remodeling and angiogenesis, was found in the selected offspring from all three experimental models and may therefore be considered as a potential marker for aggressive MM as well as a promising therapeutic target. We further show that the selection of MM cells for increased ECM-independent local growth was accompanied by overexpression of macrophage migration inhibiting factor (MIF), an important modulator of both cell cycle progression and angiogenesis, and cathepsin Z, a novel member of the family of matrix degrading proteinases.

    Notizen: The flashlamp-pumped pulsed dye laser (FPDL) was the first laser system specifically developed for the treatment of cutaneous vascular lesions such as port-wine stains (PWS), tckmgiectases and haemangiomas. Its theoretical advantages have been verified by numerous excellent clinical resultsAs there are few systematic studies on the adverse effects of this laser system, we investigated 100 consecutive patients who received FPDL therapy of PWS. Pain during and after laser therapy was a common complaint. Post-treatment erythema occurred in 29%. oedema in 73%. formation of hullae in 1%, and serous crusting in 46–83% of patients (based on our observations and the patients histories, respectively), all of which lasted for a maximum of 7 days. Furthermore, complications such as impetigo-like crusting occurred in 25%, bleeding in 12%. a pyogenic granuloma in 1%. hyperpigmentation in 27%, hypopigmentation in 1%, atrophic scarring in 3%, and an liypertrophic scar in 1%. Although most of these changes were only focal, and were predominantly transient, our results indicate that the incidence of side-effects and complications produced by the FPDI. (wavelength 585 nm, pulsewidth 450μs) may be higher than previously documented in the literature.
