There is considerable clinical and experimental evidence that cyclosporin A has powerful therapeutic effects on severe, therapy-resistant atopic dermatitis. To further clarify the mechanism of beneficial action of cyclosporin A for atopic dermatitis, we assessed its effects on mast cell morphology and on the topographical relationship between mast cells and cutaneous nerves in lesional skin of at ...

Heparan sulfate proteoglycans (HSPGs) are components of the basement membrane of various tissues. They are composed of a core protein and of the negatively charged glycosaminoglycan side chain heparan sulfate, which is covalently bound to the core protein. We previously found that in both human and murine lupus nephritis, heparan sulfate staining in the basement membrane of the glomerulus is almo ...

Tenascin-C is an extracellular matrix glycoprotein that is markedly upregulated in the dermis of psoriatic skin. In this study, we have addressed the question whether the presence of tenascin-C in the lesion or in serum is a marker for disease activity. Immunohistochemical staining of tenascin-C before and after treatment with different topical and systemic medication showed that tenascin-C remai ...

UV radiation generates reactive oxygen species, which may be involved in polymorphic light eruption. The endogenous enzymatic defense system includes catalase in the epidermis. Thirteen patients with a history of polymorphic light eruption, but free from lesions, and 13 controls were investigated from November to March. Catalase was analysed in the upper horny layer according to Colin et al.'s sp ...

The effects of fibroblast growth factor-1 (FGF-1) and FGF-2 on fibre growth and follicle function were examined using a previously described procedure to culture wool follicles. Because the FGFs bind to glycosaminoglycan components of the extra-cellular matrix, we also investigated interactions between FGF-1 and FGF-2 with heparin on wool fibre growth. Individual follicles were microdissected fro ...

Stratum corneum chymotryptic enzyme (SCCE) may be involved in desquamation, a process necessary for maintaining a normal anatomy at all sites where there is continuous turnover of cornified epithelia. Using immunohistochemistry and in situ hybridization, we have, in this work, analysed SCCE expression in the sebaceous follicle. We found expression of SCCE in luminal parts of the pilary canal, co ...

Urocanic acid (UCA), one of the skin's major components for absorbing UV radiation, is present naturally in the stratum corneum as a trans -isomer. On absorption of UVB radiation either in vitro or in the skin, UCA undergoes trans -to cis -isomerization in a dose-dependent manner. Although the mechanism by which cis -UCA suppresses immunity remains unelucidated, recent studies have indicated ...

Hereditary protein C and S deficiencies are risk factors for thrombosis. They are associated with purpura fulminans and coumarin-induced skin necrosis. Recently, necrotic livedo of the extremities, severe chilblains and severe frostbite have been observed in protein C or S deficient patients. Our study was designed to evaluate the prevalence of cold-induced acral manifestations in patients with p ...

Post-kala-azar dermal leishmaniasis can present as hypopigmented macules, erythematous to skin-coloured papules, nodules and photosensitive butterfly erythema on the face. We present a patient with disseminated annular lesions of post-kala-azar dermal leishamaniasis. The patient was treated with daily intravenous injections of sodium antimony gluconate for 120 days at a dose of 20 mg/kg body weig ...

The purpose of this study was to evaluate the frequency of skin changes among 100 patients from the Hepatogastroenterology Department of the University Hospital, Strasbourg, France who were hepatitis C virus-positive (HCV) and HIV-negative. Their clinical data were compared to those of 50 HCV-, and HIV-negative patients from the same Department, who suffered from various liver diseases. Psoriasis ...

Healthcare workers often suffer from occupational skin disease frequently caused by allergic sensitization. Therefore the patch-test results and important patient history items of 31,849 patients recorded between 1992 and 1995 in the 24 allergy departments participating in the Information Network of Departments of Dermatology (IVDK) were evaluated. Significantly increased sensitization rates comm ...

Patch testing is widely used both for clinical and experimental purposes. Although the clinical grading employed routinely is of practical value, the lack of objectivity makes it unsuitable for research purposes and dose-response analysis studies. Instrumental measuring techniques have been applied to patch test evaluation, because they enable objective quantification of different biophysical asp ...

In 2 earlier studies, we found increased nickel re-test reactivity at earlier experimentally induced nickel eczema sites. The aim of this study was to investigate if earlier contact dermatitis caused by another allergen or earlier irritant contact dermatitis also influenced the reactivity when nickel was applied topically on earlier but healed dermatitis sites. Twenty-three females with contact a ...

The purpose of the present study was to estimate the prevalence of self-reported hand dermatosis among upper secondary school pupils. All pupils in grades 1 and 3 from the four upper secondary schools in Växjö, southern Sweden, were invited to participate in the study. A previously validated questionnaire was used. Of the 2609 invited pupils, 2572 (98.6%) responded to the questionnaire. The poi ...

Kimura's disease is considered to be a Th2 type allergic reaction based on the presence of eosinophilia and IgE hyperimmunoglobulinemia. We report a 26-year-old Japanese male with this disorder associated with ulcerative colitis. IL-5 is a selective stimulator for the production of eosinophilia and is considered to play an important role in Kimura's disease. IL-5 mRNA from peripheral blood mononu ...

This is the first case in the literature describing naevi spili, café-au-lait spots and melanocytic naevi aggregated alongside Blaschko's lines. The pattern of melanocytic lesions in our patient is different from the congenital pigmentary syndromes and the segmental distribution of melanocytic naevi, the quadrant distribution of dysplastic naevi or the partial unilateral lentiginosis which here ...
