In a recent paper changes in corneocyte morphology and formation rate in psoriasis have been established. In the present study the specificity of these alternations were analysed in two situations. Early lichen planus papules were chosen as a model of hyperproliferation with hypergranulosis and orthohyperkeratosis. Hyperproliferation with parakeratosis was induced by nonanoic acid (CH3(CH2)7COOH) ...

The hypothesis that zinc pyrithione, a highly active anti-dandruff agent, exerts an anti-biosynthetic effect and reduces the epidermal turnover has been tested using guinea pig and hairless mouse skins. It has been found that enhanced mitosis caused by both stripping off the horny layers and sodium dodecyl sulphate, could be suppressed by approximately 50% by the topical application of zinc pyrith ...

Mononuclear cells in skin lesions were characterized using an indirect immunofluorescence test with monoclonal antibodies. Most cells in the dermal infiltrates were stained with OKT3 (pan T cell) antibodies and with OKT4 (helper/inducer T cell) antibodies. Fewer cells were stained with OKT8 (suppressor/cytotoxic T cell) antibodies. Results obtained using a double marking technique with monoclonal ...

Monoclonal antibodies to human T lymphocyte subsets and HLA-DR antigens were used to characterize the intra-epithelial T lymphocytes and HLA-DR reactive cells in the duodenal epithelium in dermatitis herpetiformis (DH). The expression of HLA-DR antigens on the epithelial cells was similar in patients and controls. There were significantly more Leu 2a (suppressor/ cytotoxic phenotype) reactive cell ...

Between 1969 and 1978, 44 pemphigus (p.) patients were treated in Finnish hospitals. The number of new cases was 36, giving an annual incidence of 0.76 cases per million inhabitants. The male/female ratio was 0.9:1. Nine patients had p. vulgaris (p.vu.); one p. vegetans (p.ve.); 9, p. foliaceus (p.fo.); 22, p. erythematodes (p.er.); and 3, p.NUD (p.NUD). One patient with p.er. also had myasthenia ...

Systemic immunological parameters were monitored in 26 polymorphous light eruption (PMLE) patients prior to, during and after photochemotherapy by either an oral or topical (bath) regimen. Pre-therapy investigations showed a normal immune status as regards the numbers of peripheral T-cells as well as the response of peripheral blood lymphocytes to PHA, ConA and PPD. Measurement of the immunologica ...

In the present study 46 patients with severe psoriasis maintained on long-term PUVA therapy have been followed up to 6 1/2 years after the initiation of treatment. Repeated ophthalmological examinations were performed in order to detect any early sign of lens changes. No ocular side effects attributed to the photochemotherapy were revealed during this period. Continued use of appropriate eye shiel ...

The aim of the study was to investigate whether or not extensively UVB-treated psoriatics ran a greater risk of developing skin cancer than did controls. The 85 most extensively UVB-treated psoriasis patients during recent decades have been investigated with regard to premalignant and malignant skin lesions and compared with a population matched for age, sex, and geographic region. The prevalence ...

By using the colcemid method, the presence of a diurnal variation for the mitosis index was confirmed, showing a definite minimum during the night in the sebaceous gland of the Syrian hamster ear. Furthermore, the number of all labelled cells and the quotient "single-labelled 14C-cells + double-labelled cells/single-labelled 3H-cells" determined with double-labelling autoradiography ([3H] and [14C ...

Immunofluorescence studies were carried out in 7 cases of lichen amyloidosus, chiefly to detect deposition of complement components in the cutaneous lesions. Examination of skin biopsy specimens revealed deposition of Clq, C3, C9 and IgM in all the patients studied. Complement and immunoglobulin levels by assays of simultaneously obtained serum samples were found to be almost within the normal lim ...

Lymphocytotoxic autoantibody (LCTA) was studied in 9 patients with active pemphigus and 19 patients with active systemic lupus erythematosus (SLE). All patients with SLE showed high titres of LCTA but only one patient with pemphigus had LCTA. In this paper we discuss the immunological significance of LCTA and the difference in the incidence of LCTA between pemphigus and SLE. In addition we present ...

A case of genital leukoderma syphiliticum was analysed submicroscopically. No treponema pallidum organisms could be detected intra- or extracellularly in the epidermis or in the dermis. The melanocytes were only slightly reduced in number and had mostly normal outlines. The melanogenesis was impaired and small melanosomes with decreased deposition of melanin were mostly produced at the expense of ...

In 76 cases (5.8%) of a population of 1310 cases (examined by patch tests for possible contact dermatitis) a combined (coupled) allergy was found to nickel and cobalt. In 37 out of the 76 cases this combined allergy was associated with clinical dermatitis of the hands. Statistical chi-square analysis revealed that in the original population of patients examined, apart from a strong association bet ...

During PUVA treatment a 66-year-old woman with mycosis fungoides in stage III suddenly developed widespread papulonodular lesions of alarming clinical and histological appearance. There was rapid spontaneous and complete regression of the eruptions, which was probably an expression of transient lymphomatoid papulosis in connection with MF.

A patient developed concomitantly chondritis of the two auricles, diffuse cutaneous vasculitis and actinic granulomas. Alterations in skin and cartilage were prominent in the elastic tissue. Anticollagen type II antibodies were absent from the serum and there was no deposit of immunoreactants in cartilages. In this form of relapsing polychondritis, the pathomechanism resembles that of diffuse acti ...

A 3 1/2-year-old haemophilic child, repeatedly transfused with blood products, developed pemphigus foliaceus with presence in serum of both intercellular and anti-cytomegalovirus antibodies at high titre. The locus A26, which seems to be a genetic marker of pemphigus, was detected in his haplotype. Cytomegalovirus infection of transfusional origin is suspected to have triggered the outbreak of pem ...

All 22 cases of infections with Microsporum canis verified by culture during a five-year period were surveyed. Only tinea corporis was found. The clinical picture was varied and in more than half of the cases the preliminary diagnosis was other than tinea. The classical tinea capitis was not found in any case. Direct KOH-mounts showed poor correlation to the cultural findings (positive in 33%). It ...
