Reconstructed human skin equivalents are currently being investigated as in vitro models for the prediction of human skin toxicity and irritation responses. Three different industrial reconstructed skin models (EpiDerm, Episkin and SkinEthic) and one in-house equivalent were characterized and compared using light microscopy, immunohistochemistry and reduction of (3-[4,5-dimethylthiazole-2-yl]-2, ...

The composition of free and covalently bound lipids in reconstructed epithelia generated with normal human keratinocytes, HaCaT cells and squamous carcinoma cells was investigated and compared with native skin. Stratum corneum isolated from native human and reconstructed epidermis was subjected to extensive extraction with chloroform-methanol mixtures followed by alkaline hydrolysis to release co ...

Exposure of the epidermis to nickel-containing compounds is one of the most common causes of contact allergy and may indicate that exposure of skin cells to nickel ions causes stress. In this study, cytotoxicity assays upon human keratinocytes and fibroblasts in monolayer culture indicated a 50% decrease in viability of both cell types at nickel sulphate concentrations in excess of 10-3 M. To inv ...

In human skin, there are 2 types of epidermal differentiation: normal differentiation, characterized by keratin 10 expression, and alternative differentiation. Alternative differentiation may be regeneration-associated differentiation (keratin 6 and 16) or re-induction of embryonic differentiation (expression of keratin 13, 15 and 19). The purpose of this study was to investigate the effect of th ...

The levels of proelafin peptides in the sera of patients with pustulosis palmoplantaris, a unique type of localized pustular psoriasis, and generalized pustular psoriasis were determined by competitive enzyme-linked immunosorbent assays using antibodies against synthetic proelafin polypeptides corresponding to the elastase inhibitor (elafin) and transglutaminase substrate domains. The sera of pat ...

The aetiology of atopic dermatitis is unknown, but is probably multifactorial, with interactions between several genetic and environmental factors. Twin studies indicate a strong genetic factor, but the susceptibility genes are unknown. This paper, describing the phenotypes of family material, forms part of a large genetic study seeking to identify susceptibility genes for atopic dermatitis by li ...

In order to study the flare-up of contact allergy, 35 patients with a contact allergy to gold were given an intramuscular injection of 10 mg gold sodium thiomalate, i.e. the anti-rheumatic drug Myocrisin®. Clinical reactions comprised an eczematous flare-up of previously positive patch tests to gold and of a previous dermatitis, which occurred in 80% and 26%, respectively; a toxicoderma-like ras ...

Wealing and pruritic, long­lasting papules are a common nuisance from mosquito bites. Antihistamines can be expected to decrease wealing, but their effect on the delayed bite symptoms needs to be elucidated. We studied the effect of ebastine in 28 mosquito-bite sensitive adult subjects exposed to Aedes communis bites in the field. Ebastine 20 mg and placebo were given for 4 days in a crossover f ...

For didactic and documentation purposes the dermatoscopic ABCD rule and the dermatoscopic risk stratification have been proposed. The aim of this investigation was to compare the ability of the 2 methods to separate patients with cutaneous malignant melanoma from individuals with other pigmented skin lesions. Three dermatologists, experienced users of dermatoscopy, assessed macroscopic clinical a ...

Rosacea fulminans is a rare disorder of unknown cause that mainly affects postadolescent women, with abrupt onset and disfiguring course if left untreated. The simultaneous occurrence of rosacea fulminans and inflammatory bowel disease is rare and has been reported predominantly in the setting of ulcerative colitis. We describe here a case of rosacea fulminans in a patient with Crohn's disease an ...

The aim of this retrospective study was to evaluate the initial video-radiology and manometry in 40 consecutive patients with systemic sclerosis (n =21) or suspected systemic sclerosis (n =19) in relation to oesophageal symptoms; and, furthermore, to evaluate the consequence of radiographic or manometric findings in the oesophagus on diagnosis and treatment. Evaluating oesophageal abnormalities i ...

Imiquimod is a recently developed imidazoquinolin heterocyclic amine that is an immune response modifier. Treatment with topical 5% imiquimod cream has shown promising results in the treatment of genital warts in immunocompetent individuals. We report here the first case of successful treatment with topical 5% imiquimod cream of facial verrucae in an individual with human immunodeficiency virus. ...

The prevalence of sexually transmitted diseases (STDs) diagnosed in men attending an outpatients' clinic for gay men from 1983 to 1997 and the results from a questionnaire survey concerning sexual behaviour conducted in 1994-96 are reported. The prevalence of gonorrhoea and chlamydia has decreased during the period, although in 1997 there was a micro-epidemic of gonorrhoea in gay men in Gothenbur ...

Mucocutaneous diseases are common in HIV-infected patients. The aim of the present study was to determine the observed frequency of skin diseases and their prognostic significance for the progression of HIV infection. In a cohort of 150 HIV-infected patients diagnosed from 1986 to 1987 the number of mucocutaneous diseases, the CD4+ cell count, time to development of AIDS and survival time were re ...
