{"title":"Pityrosporum ovale in healthy children, infantile seborrhoeic dermatitis and atopic dermatitis.","authors":"A Broberg","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>The occurrence of Pityrosporum ovale was studied in healthy children, children with infantile seborrhoeic dermatitis (ISD) and in patients with atopic dermatitis (AD). Twenty children with ISD and twenty healthy infants were subjected to culture for P. ovale. Positive cultures were found in 18 of 20 infants with ISD, compared with 4 of 20 controls. The same culture medium containing olive oil as one of the lipids was used to evaluate the frequency of positive P. ovale cultures in 60 patients with AD, 40 patients with rhinoconjunctivitis and/or asthma (RA) and 40 children and young adults with no atopic history (HC). The results of the quantitative cultures from the forehead did not differ between the groups. P. ovale cultures were positive in 0-20% of children aged 0-10 years and in 60-90% of the 11-20-year-old subjects. Positive P. ovale cultures were found in 87% of 138 healthy children aged 2 months to 15 years when cultures were performed on a medium containing whole fat cows' milk as one lipid source. The largest number of colonies was found among children aged 2-23 months and among children older than 9 years. The occurrence of specific IgE antibodies to P. ovale was evaluated with a skin prick test (SPT) and RAST and compared in 3 groups (AD, RA, HC) of patients aged 0-20 years. Specific IgE were found most often in patients with AD. In patients with AD on different parts of the body, 15% had a positive SPT to P. ovale. In another group of patients, aged 14-53 years, with AD localised mainly to the head and neck area, the SPT was positive in 55% of the patients. Sera from 13 patients with positive SPT to P. ovale were further analysed with IgE immunoblotting using both P. ovale and C. albicans antigens. Simultaneous IgE-binding to both these yeasts was found in 5 sera and these were analysed with RAST-inhibition. Cross-reacting IgE antibodies to P. ovale and C. albicans were found in two of these sera. Cross-reacting sera were pooled and used as an IgE probe in crossed radioimmunoelectrophoresis and Tandem-crossed immunoelectrophoresis. Cross-reacting epitopes were suggested to be located in the mannan polysaccharide of C. albicans and in a high molecular weight fraction of P. ovale.(ABSTRACT TRUNCATED AT 400 WORDS)</p>","PeriodicalId":6960,"journal":{"name":"Acta dermato-venereologica.

{"title":"Biophysical properties of dry atopic and normal skin with special reference to effects of skin care products.","authors":"M Lodén","doi":"10.2340/00015555192148","DOIUrl":"https://doi.org/10.2340/00015555192148","url":null,"abstract":"<p><p>During recent years several highly developed non-invasive methods for evaluation of skin physiology and pathology have been introduced. Against this background, the present studies were undertaken with the primary aim of assessing the effects of various skin care products on some properties of the skin. Skin topography was measured by profilometry on skin replicas, friction with a newly developed friction instrument, capacitance with a Corneometer, and barrier function both with an Evaporimeter to assess transepidermal water loss (TEWL) and by application of an irritant followed by measurement of the resulting irritative reaction. Initially some of the techniques were used to further characterize the differences between dry atopic skin and normal skin. Dry skin exhibits increased values of roughness parameters and a reduced number of topographical peaks. TEWL is increased, indicating impaired barrier function. The friction and capacitance are lower and correlate significantly to each other, whereas TEWL does not appear to relate to either of these parameters. The use of a scrub cream removes the outermost part of the stratum corneum, resulting in a smoother skin. Application of moisturizers modifies the frictional response of the skin. The friction instrument gave results comparable to those of panelists trained in sensory evaluation. The study suggests that measurement of skin friction can be used to predict the degree of liking of moisturizers. Furthermore, moisturizers increase the skin hydration. They provide water directly to the skin from their water phase. Skin hydration also increases with increased degree of occlusion, as measured as a decrease in TEWL. Moisturizers may also alter the diffusional resistance of the stratum corneum and reduce the skin susceptibility to the surfactant sodium lauryl sulphate (SLS). Lipids in moisturizers may influence already developed SLS-induced irritation. A significantly lower degree of irritation was found in areas treated with canola oil and its sterol-enriched fraction than in an area treated with water. These findings emphasize that skin care products do not only form an inert, epicutaneous layer, but that they may penetrate and influence the structure and function of the skin.</p>","PeriodicalId":6960,"journal":{"name":"Acta dermato-venereologica.

{"title":"Hereditary palmoplantar keratoderma and dermatophytosis in the northernmost county of Sweden (Norrbotten).","authors":"Povl Gamborg Nielsen","doi":"10.2340/00015555188160","DOIUrl":"https://doi.org/10.2340/00015555188160","url":null,"abstract":"Clinical reports of hereditary palmoplantar keratoderma are generally based on a limited number of patients. In 1967 the prevalence in the northernmost county of Sweden (Norrbotten) was shown to be 0.55%. In 1982 it was possible to trace half of the original propositi from that study. Among these families, a severe clinical form with a presumed recessive inheritance could be distinguished. The clinical pictures in relatives of the original propositi were described, and other diseases were listed together with those in patients from previously performed studies. The frequency of dermatophytosis was 36.2%, which was equal to a prevalence of 37.6%. T. mentagrophytes occurred significantly more often and immunological factors, such as increased presence of blood group A, specific dermatophyte IgG antibodies, precipitating antibodies and an immunological in vitro reaction to keratin, supported differences in the distribution of dermatophytes. However, the amount of keratin was considered the most important factor for the affinity of dermatophytes to the palms and soles. A vesicular eruption along the hyperkeratotic border and a mononuclear cell infiltrate were often reported. Such reactions were interpreted as immunological reactions to dermatophytosis. Scaling and fissuring were considered clinical signs of dermatophyte infections and not a part of the originally reported clinical picture. Results of the histopathological study corresponded to previously reported descriptions of the Unna-Thost variety. However, it has recently been reported that the histopathological picture of this variety was based on histopathological features of epidermolytic palmoplantar keratoderma. The existence on the Continent of the Unna-Thost variety was therefore questioned. Histopathological features of epidermolytic palmoplantar keratoderma were not found in the County of Norrbotten and the designation \"Diffuse HPPK type Norrbotten\" has therefore been proposed. The histopathological picture of the presumed recessive variety did not differ from that of the dominant variety but ultrastructural characteristics differentiated it from Mal de Meleda and the dominant variety. It was therefore concluded that a new variety with a presumed recessive inheritance was found.","PeriodicalId":6960,"journal":{"name":"Acta dermato-venereologica.

The mean number of localizations was significantly higher in hairdressers than in teachers; this was caused by greater affection of fingers in hairdressers compared to teachers. Seventy-five percent of the hairdressers and 79% of the teachers had only modest or very moderate erythema. Fourteen percent and 5%, respectively, had vesicular dermatitis. The right upper limb was most affected in both hairdressers and teachers. Three subgroups of hairdressers were considered: hairdressers with atopic dermatitis, those with only atopic mucosal symptoms and those without atopic symptoms.
