Opis:
The pathogenesis of atopic dermatitis (AD) is a very complicated process that involves an intricate array of molecules. Nowadays it is generally accepted that cytokines play an important role in the progression of the clinical presentation of atopic dermatitis. However, emerging data point to the possible involvement of cornified envelope proteins in the development of skin barrier dysfunction and illness. Unfortunately, our knowledge on relation of particular genotype to progression of AD is very limited. Therefore, intensive studies are needed to increase our understanding of genetic background of atopic dermatitis. Hopefully the future research will identify new factors that help us to determine the additional risk for certain patients with atopic dermatitis.

Opis:
Introduction. Atopic dermatitis (AD) is a chronic and recurrent disease with an inflammatory background. Genetic and environmental factors are responsible for the occurrence and development of this dermatosis. Objective. The aim of the study was to assess the frequency of colonisation of the nasal vestibule and apparently healthy skin by S. aureus, and to assess dermal lesions for superinfection with S. aureus in AD patients. Materials and method. The research was performed on a population of 100 AD patients. Three smears were collected for microbiological investigations: from the anterior nares, from apparently healthy skin and from lesioned skin. On collection, the material was cultured on mediums provided by the bioMerieux and Argenta companies. The strains were identified and their sensitivity to antibiotics assessed by means of the Vitek2 system (bioMerieux). Results. S. aureus was present in at least one location in 90%. 44% presented S. aureus colonization of apparently healthy skin and within skin lesions. In the case of 23%, this particular pathogen was detected only in skin lesions, whereas 6% had a positive result within the area of apparently healthy skin. In total, S. aureus was detected in the skin of 73%. In 61%, apparently healthy skin had been colonized with S. aureus, whereas in 81% colonization was proved within the skin lesions. S. aureus was detected in the nasal vestibule of 85%. Among the group with S. aureus in their anterior nares, the pathogen was also found on the skin surface of 77%. Conclusions. S. aureus colonises skin in most AD patients. Most AD patients carry S. aureus in their nasal vestibules. S. aureus does not seem to colonise healthy skin as often as skin lesions in young people. The vast majority of S. aureus strains were sensitive to local antibiotics. Most S. aureus strains produced penicillinase.

Opis:
Introduction and objective. Farmers are at high risk of occupational skin diseases which may start already during vocational training. This study was aimed at identification of risk factors for work-related skin diseases among vocational students of agriculture. Materials and method. The study involved 440 students (245 males, 195 females aged 17–21 years) in 11 vocational schools which were at least 100 km from each other. The protocol included a physician-managed questionnaire and medical examination, skin prick tests, patch tests, total IgE and Phadiatop. Logistic regression model was used for the identification of relevant risk factors. Results. Work-related dermatoses were diagnosed in 29 study participants (6.6%, 95%CI: 4.3–8.9%): eczema in 22, urticaria in 14, and co-existence of both in 7 students. Significant risk factors for work-related eczema were: history of respiratory allergy (OR=10.10; p<0.001), history of eczema (itchy rash) provoked by wet work and detergents before entering the school (OR=5.85; p<0.001), as well as history of contact dermatitis to metals, rubber or cosmetics prior to inscription (OR=2.84; p=0.016), and family history of any skin disease (OR=2.99; p=0.013). Significant risk factors for work-related urticaria were: history of allergic rhinitis and asthma prior to inscription (OR=7.29; p=0.006), positive skin prick tests to work place allergens (OR=4.65; p=0.002) and to environmental allergens (OR=3.79; p=0.009), and positive Phadiatop test (OR=3.61; p=0.013). Conclusions. Work-related skin diseases are common among vocational students of agriculture. Atopy, past history of asthma, allergic rhinitis, and eczema (either atopic, allergic or irritant) are relevant risk factors for work-related eczema and urticaria in young farmers, along with family history of any skin disease. Positive skin prick tests seem relevant, especially in the case of urticaria. Asking simple, aimed questions during health checks while enrolling students into agricultural schools would suffice to identify students at risk for work-related eczema and urticaria, giving them the chance for selecting a safer profession, and hopefully avoiding an occupational disease in the future.

Opis:
Atopic eczema (AE) is a multifactorial skin disease caused by a variety of factors such as genetic conditions, alterated skin structure, immunologic deviations and environmental factors, among others. There are two main subtypes of AE, i.e. the IgE-associated (“atopic eczema”) and the non-IgE-associated type (“nonatopic eczema”) with different prognosis concerning the development of respiratory diseases (“atopy march”). Recently, it was demonstrated that Filaggrin (= fi lament-aggregating protein, FL) is a major gene for atopic eczema. Filaggrin binds to and aggregates the keratin cytoskeleton in the epidermis. Homozygous FLG mutation leads to complete loss of fi laggrin expression in skin. Half or more of children with moderate to severe AE carry FLG mutations. Moreover, fi laggrin loss-of-function mutations predispose to phenotypes involved in the atopy march. The altered skin structure and a defi ciency in antimicrobial peptides favour colonization with Staphylococcus aureus and yeasts (Malassezia sp.). Sensitization to the yeast occurs almost exclusively in AE patients. S. aureus enterotoxins with superantigenic activity stimulate activation of T cells and macrophages. So far, AE skin lesions are orchestrated by the local tissue expression of proinfl ammatory cytokines and chemokines with activation of T lymphocytes, dendritic cells, macrophages, keratinocytes, mast cells, and eosinophils which lead to the skin infl ammatory responses. From the therapeutic point of view, besides emollients and local corticosteroids, topic immunomodulatory drugs (tacrolimus and pimecrolimus) have substantially improved the treatment of AE.
