Using non-radioactive in situ hybridization we studied the expression of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and PolyA+ RNA in psoriasis and normal skin, and GAPDH in epidermis following application of a range of noxious stimuli, including ultraviolet radiation, Sellotape stripping and various irritants. In keeping with what might have been expected from previous results on cell cul ...

Retinoic acid, vitamin D3 and triiodothyronine regulate keratinocyte proliferation and differentiation - processes that are disturbed in psoriatic skin - via binding to nuclear receptors for retinoic acid (RAR-α,-γ), vitamin D3 (VDR), thyroid hormone (TR-α,-β) plus the common heterodimer partners, the 9-cis-retinoic acid receptors (RXR-α,-β). By using a new quantitative real-time polymerase ...

In order to develop a more efficient method of introducing genes into keratinocytes in vivo , we intradermally injected DNA bound to high mobility group 1 protein, thereby taking advantages of the naked DNA and hemagglutinating virus of the Japan-liposome method reported previously. First we performed a gel mobility shift assay, which confirmed DNA binding to high mobility group 1. Then we injec ...

Langerhans' cells are epidermal dendritic cells, derived from blood precursors. Their main function is antigen presentation to T-cells. They are able to express neuronal proteins, such as neuron­specific enolase or substance P-receptor. They are closely associated with nerve fibres. PGP9.5 is the most specific neuronal protein in the epidermis. Epidermal Langerhans' cells can express PGP9.5 if d ...

Lesional skin in patients with inflammatory skin diseases is often colonized with Staphylococcus aureus , which is capable of releasing superantigens. We therefore studied whether application of superantigen on the skin led to release of cytokines, especially IL-1β. Suction blisters were raised on vehicle- and superantigen-treated skin and IL-1β protein levels measured in suction blister fluid ...

Superficial blood perfusion was monitored using laser-Doppler perfusion imaging in connection with a phase III clinical trial comparing photodynamic therapy, utilizing topically applied δ-aminolevulinic acid, with cryotherapy of basal cell carcinomas. A total of 526 images were recorded before and immediately after the treatment and during the follow-up period. Before treatment, the lesions exhi ...

The effect of thalidomide on itch was studied in 11 patients with chronic pruritus from psoriasis, eczema, nodular prurigo, senile pruritus and primary biliary cirrhosis. Itch, assessed subjectively by the patients on a 10 cm line and measured objectively as nocturnal scratch movement, was decreased by thalidomide 200 mg on the 2 nights it was given. There was no improvement in the underlying dis ...

Therapy of localized scleroderma is unsatisfactory, with numerous treatments being used that have only limited success or considerable side-effects. The aim of this trial was to determine whether topical photodynamic therapy would be effective in patients with localized scleroderma. Five patients with progressive disease, in whom conventional therapies had failed, were treated by application of a ...

In longstanding venous ulcers, the development of lipodermatosclerosis of the skin surrounding the ulcer is common. According to our clinical experience lipodermatosclerosis impairs the opportunities for the ulcer to heal. In this combined retrospective and prospective study the lipodermatosclerotic skin area was excised in 7 non-healing venous ulcers and then covered with split skin graft. All 7 ...

Air-borne contact dermatitis caused by Parthenium hysterophorus is a serious problem in India. Patients with this condition have to use corticosteroids regularly in order to maintain clinical remissions, but prolonged usage causes serious side-effects. The weed cannot be eradicated. We have used 3 therapeutic regimens with azathioprine, which led to an effective control with minimal side-effects ...

Of patch-tested patients with dermatitis, 4-5% are allergic to corticosteroids. Four groups of corticosteroids are recognized (A-D), where substances from the same group may cross-react. We investigated the potential cross-reactivity pattern and dose-response relationship for several corticosteroids from group A. We also included the corresponding aldehyde to hydrocortisone, as this degradation p ...

Dorfman-Chanarin syndrome is a rare, autosomal recessive inherited lipid storage disease with congenital ichthyotic erythroderma due to an acylglycerol recycling defect. Demonstration of lipid vacuoles in neutrophils from peripheral blood smears (Jordans' anomaly) in patients with ichthyotic erythroderma leads to the diagnosis. In spite of frequent liver, muscle, ear, eye and central nervous syst ...

A case-control study was performed in order to assess risk factors for repeated sexually transmitted diseases. The study comprised 101 patients who had had sexually transmitted diseases 3 or more times during their lives and 182 controls who had no history of sexually transmitted disease. The subjects all attended the City Department for Skin and Venereal Diseases in Belgrade, Yugoslavia, from Ju ...
