A cellular p53 response, DNA repair enzymes and melanin pigmentation are important strategies utilized by skin keratinocytes against impairment caused by ultraviolet radiation (UVR). In this study a double-immunofluorescence technique was used to investigate UVR-induced thymine dimers and p53 protein simultaneously. Four healthy volunteers were irradiated on both sides of their buttock skin with ...

Ultraviolet irradiation influences natural killer cell function both in vitro and in vivo . The postulated ultraviolet photoreceptor in the epidermis, urocanic acid, has been reported to depress the cytotoxic activity of human natural killer cells. Therefore, this study investigated whether this would occur through specific second messengers, using a radioimmunoassay for intracellular adenosine ...

The pathogenesis of AIDS-associated eosinophilic folliculitis is still unknown. The expression of chemokines and Th2-type cytokines is increased in other conditions associated with tissue eosinophilia and in allergic reactions. We evaluated the mRNA expression by reverse transcriptase polymerase chain reaction of two Th2 cytokines (interleukin-4 and interleukin-5) and of two chemokines (RANTES an ...

Host-defence defects in hidradenitis suppurativa patients have been suspected, but not proven. Activated neutrophils can destroy the surrounding tissues by a release of reactive oxygen species and active proteases. Peripheral neutrophils from 15 female patients (mean age 46, range 27-57 years) in an inactive state of their hidradenitis suppurativa, were studied and compared with 15 age-matched he ...

Sorption-desorption and moisture accumulation tests are simple and quick methods for the in vivo functional analysis of stratum corneum hydration kinetics. The aim of this study was to evaluate the hydration dynamics of the uninvolved and affected skin of children with atopic dermatitis and to compare them with the skin of healthy children. The study investigated 45 children. The dynamic tests w ...

Moisturizers are used for the treatment of dry and irritated skin. The benefit of moisturizers when used on normal skin has recently been challenged, since an earlier study indicated that the increased hydration that follows long-term use of moisturizers on normal skin may facilitate penetration of irritants. The aim of the present study was to evaluate short-term use of 2 different moisturizer ...

A questionnaire was constructed for the evaluation and measurement of pruritus. The questionnaire, based on the short form of the McGill Pain Questionnaire, was tested in 145 patients suffering from uremic pruritus andcurrently undergoing hemodialysis treatment in 3 centers. The newly developed questionnaire proved to be reliable and provided valid data on the sensory, affective and overall inten ...

The frequency of various diagnoses of pigmented lesions, their distribution on various body sites and the seasonal variations in their diagnoses were studied according to the specimen of pigmented lesions sent to a laboratory for histopathological examination. From the total number of 18,402 investigated lesions, 7,682 were excised from males and 10,720 from females. Melanoma was diagnosed in 2.5 ...

The data from a questionnaire-based study of 5,739 members of thepsoriasis associationsof Denmark, Finland, Iceland,Norway, Sweden and the Faeroe Islands showed that the two most commonly used active agents were topical steroids (89.7 % total use and 49.4 % present use) and calcipotriol (73.1 % total use and 35.8 % present use), with only small variations between the countries. Marked differences ...

There is still some doubt about the reproducibility of patch tests. A sound assessment needs optimized and unbiased studies. This study analysed the results of a double-blind multicentre study with nickel sulfate and potassium dichromate patch tests attached synchronously to both sides of the back of patients with a history of nickel allergy, conducted with a highly standardized randomized test s ...

Conflicting results regarding the association of a polymorphism at codon 72 of the p53 tumour suppressor gene and susceptibility to develop human papilloma virus (HPV)-associated cervical cancer have been published over the last year, implicating differences in ethnic background, sample origin, sample size and/or detection assay. The material for this study was collected in the identical geograph ...

Human papillomavirus (HPV) type 7 is frequently found in butchers' warts and has been demonstrated in oral and facial warts of HIV-infected patients. The reservoirs of HPV7 and the route of transmission are still unclear. Here we describe an HIV-negative, otherwise healthy patient with extensive, recurrent orofacial papillomatosis whose immune status proved to be normal and who had no history of ...

Pyodermatitis-pyostomatitis vegetans is a rare, polymorphous inflammatory disorder of the skin and oral mucosa first described by Hallopeau in 1898. On the skin papules, pustules and reddish brown annular vegetating plaques develop, most frequently in the intertriginous areas. In the mouth, yellowish flat ulcerations arise, typically in the shape of "snail tracks". The association with inflammato ...
