Reconstruction of epidermis on a chitosan cross-linked collagen-GAG lattice: effect of fibroblasts.
Saintigny G, Bonnard M, Damour O, Collombel C.
Reconstruction of epidermis on a fibroblast containing chitosan cross-linked collagen-GAG lattice at the air-liquid interface gives rise to a multilayered stratified epithelium, covered with a compact stratum corneum. Immunohistological studies reveal that the markers of epidermal differentiation are essentially distributed as in normal human skin and that the major proteins of the dermal-epiderma ...

Expression of stratum corneum chymotryptic enzyme in reconstructed human epidermis and its suppression by retinoic acid.
Egelrud T, Régnier M, Sondell B, Shroot B, Schmidt R.
The aim of the present study was to investigate the presence of stratum corneum chymotryptic enzyme (SCCE) in human epidermis reconstructed in vitro on dead de-epidermized dermis and the effect of retinoic acid (RA) on its expression. SCCE is a recently discovered serine proteinase which has been purified from human stratum corneum, and evidence has been presented that it may play a role in stratu ...

High-frequency ultrasound scan for non-invasive cross-sectional imaging of psoriasis.
Olsen LO, Serup J.
Seventeen patients with psoriasis vulgaris were studied by high-frequency (20 MHz) ultrasound imaging. An echo-lucent band located at the dermo-epidermal junction was characteristic. The band represents the combination of acanthotic epidermal thickening and inflammation. Thus, with ultrasound the site within the skin where primary events take place can be studied and followed non-invasively, i.e. ...

Longitudinal study of excretion of metabolites of polycyclic aromatic hydrocarbons in urine from two psoriatic patients.
Hansen AM, Poulsen OM, Menné T.
Coal tar, which is widely used in the treatment of patients with atopic dermatitis, chronic eczema, and psoriasis, contains a large amount of polycyclic aromatic hydrocarbons (PAH). Some of the PAH compounds are known either to be carcinogenic or to potentiate the effects of other carcinogenic substances. In the present study, the excretion patterns of 1-hydroxypyrene (metabolite of pyrene) and al ...

Modulation of eicosanoid formation by lesional skin of psoriasis: an ex vivo skin model.
Fogh K, Iversen L, Herlin T, Kragballe K.
The purpose of the present study was to develop an ex vivo skin model to determine the capacity of lesional skin of psoriasis to form leukotriene B4 and other eicosanoids. Keratomed skin samples were incubated in the presence of the calcium ionophore A23187 and arachidonic acid for 45 min at 37 degrees C. After extraction of lipids, eicosanoids were determined by quantitative reversed-phase high-p ...

UV-related skin conditions and Langerhans' cell populations in human skin.
Bergfelt L.
Chronic sun exposure and cumulative exposures to PUVA are associated with a risk of development of non-melanoma skin cancer. Acute UV irradiation reduces the number of epidermal antigen-presenting Langerhans' cells in the skin. Alterations in the Langerhans' cell population could be relevant to a disturbance in the cutaneous immune response in UV-exposed skin. Therefore the density of CDla+ and AT ...

alpha-Amino-n-butyric acid methyl ester induces concentrative uptake of L-dopa in human Langerhans' cells normally not operative for L-dopa transport.
Falck B, Andersson L, Mikulowska A, Ronquist G.
We recently reported the existence of two kinds of human epidermal Langerhans' cells (LC), one which can take up and accumulate L-dopa and one which cannot. The dopa(+) LC take up L-dopa by carrier-mediated exchange diffusion, that is, the influx of L-dopa and the outflow of an intracellular substance are linked via the same carrier. The nature of the fundamental difference between L-dopa(+) and L ...

Effect of pressure on in vitro percutaneous absorption of caffeine
Treffel P, Panisset F, Humbert P, Remoussenard O, Bechtel Y, Agache P
The effect of increased pressure, which is a mechanical property of massage, was investigated on the percutaneous absorption of an amphiphilic compound (caffeine) in vitro on Franz diffusion cells, using excised human skin. 50 microliters of either a 320 micrograms/ml or a 15 mg/ml acetone solution of caffeine were pipetted onto the surface of each skin sample, which represented caffeine skin depo ...

The temperature effect on in vitro penetration of sodium lauryl sulfate and nickel chloride through human skin.
Emilson A, Lindberg M, Forslind B.
Irritant contact dermatitis is a major problem in dermatology. One important group of substances causing irritant dermatitis is detergents. Exposure of the skin to detergents is frequent in both work and domestic environments. In the present paper we have studied how the penetration through the skin, and thus the effect, of the detergent sodium lauryl sulfate (SLS) is altered when the temperature ...

Pemphigus foliaceus induced by nifedipine.
Kim SC, Won JH, Ahn SK.
We report a case of pemphigus foliaceus caused by nifedipine. In this case casual rechallenge with nifedipine confirmed that this drug was the causative agent. The skin lesions cleared quickly after withdrawal of the drug and treatment with a short course of oral steroids. To our knowledge, this is the first reported patient with nifedipine-induced pemphigus.

Pseudocyst of the ear. Report of three cases.
González M, Ratón JA, Manzano D, Zabala R, Landa N, Díaz-Pérez JL.
Pseudocyst of the ear is a rare entity with controversial pathogenesis. Usually it is presented as a solitary, unilateral, fluctuant and non-inflammatory tumour of the ear with overlying normal skin. It occurs most often in young adult males. Incission reveals a serous liquid, with the consistency of olive oil, contained in the cyst-like lesion. Histopathology shows an intracartilaginous cavity wi ...

Irritant reactivity is a better risk marker for nickel sensitization than atopy.
Elsner P, Burg G.
In order to optimize patch test strategies and counselling in occupational dermatology, it is important to identify risk markers of contact sensitization. Since nickel is the most frequent contact allergen in European countries, we studied the potential of the irritant response to sodium lauryl sulfate (SLS) to predict nickel sensitization. In 100 patients subsequently tested in our patch test cli ...

Squamous cell carcinoma in localized scleroderma following immunosuppressive therapy with azathioprine.
Nachbar F, Stolz W, Volkenandt M, Meurer M.
A 40-year-old man presented with an ulcerated tumour in a fibrotic plaque on the dorsum of his left foot. Due to severe localized scleroderma, the patient had been treated with azathioprine 10 years earlier. Histopathology of the excised tumour revealed an anaplastic squamous cell carcinoma within a scar of localized scleroderma. The case demonstrates that not only patients with tense scar tissue ...

Adverse immune reactions to gold in rheumatoid arthritis: lack of skin reactivity.
Goldermann R, Schuppe HC, Gleichmann E, Kind P, Merk H, Rau R, Goerz G.
Adverse immune reactions develop in up to 30% of patients treated with gold compounds. However, sensitization to gold(I) drugs is rarely demonstrated by in vivo or in vitro testing. Recent data from a mouse model provides evidence that gold(I) is oxidized to gold(III) before T cells are sensitized. To study the diagnostic value of skin tests, patch testing with various gold compounds - including g ...

Two cases of vulvodynia with unusual causes.
Perniciaro C, Bustamante AS Jr, Gutierrez MM.
Two women with vulvodynia are described. In one patient, severe chronic vulvodynia developed secondary to contact dermatitis. Patch-testing confirmed the offending allergens. A second patient with vulvodynia was severely dermatographic. Evaluation of patients with vulvodynia should include an appropriate medical history and diagnostic studies to exclude contact dermatitis and dermatographism. Effe ...
