Induced sputum evaluation in restorers and conservators of cultural heritage.

The objective of this study was to examine induced sputum (IS) cells profile from restorers/conservators of cultural heritage (restorers) with no lower airway symptoms and normal ventilatory lung function. The study involved 22 restorers and 48 control workers. Medical interview, physical examination, spirometry, skin prick testing to inhalatory allergens, and IS collection were performed.

Pyroglyphid mites as a source of work-related allergens.

Pyroglyphid mites are primarily associated with allergen exposure at home; hence the name house dust mites. However, we have found numerous studies reporting pyroglyhid mite levels in public and occupational settings. This review presents the findings of house dust mite allergens (family Pyroglyphidae, species Dermatophagoides) as potential work-related risk factors and proposes occupations at risk of house dust mite-related diseases.

Upper respiratory impairment in restorers of cultural heritage.

Background: There is a paucity of data regarding respiratory health in restorers of cultural heritage or similar occupations, such as visual artists or museum workers, although they are exposed to a complex mixture of various respiratory hazards.

Aims: To evaluate atopy and respiratory health parameters, including bronchial and nasal non-specific reactivity, in restorers and conservators of cultural heritage (restorers).

Methods: Fifty-six restorers and 62 controls provided general data and data on ever experienced rhinitic or asthma-like symptoms, spirometry, non-specific bronchial and nasal responsiveness to histamine, skin prick testing to common inhalational allergens and serum total IgE levels.

[Immunological aspects of asbestos-related diseases].

Asbestos is a generic name for a group of silicate minerals. The most common are chrysotile, crocidolite, amosite, tremolite and anthophyllite. Exposure to asbestos may cause asbestos-related non-malignant diseases of the lung and pleura, including asbestosis, pleural plaques, diffuse pleural fibrosis, small airway disease, and malignant diseases such as lung cancer and malignant mesothelioma.

[Allergotoxicology: research of pollutant influence on the development of allergic reactions].

Allergotoxicology studies the influence of pollutants on the development of allergic reactions and diseases. At the beginning, the research was focused on outdoor air pollutants, while recently it turns to the indoor environment, mainly because people this is where people spend most of their time. Air pollutants may be solid, soluble, or gaseous particles in nature, and they can differ in size, structure, and sources.

Association of neuroticism with sick building syndrome, quality of life and psychomotor performance.

In a group of 221 healthy employees of both sexes the relationship between neuroticism, and perceived quality of life (WHOQOL), inadequate work organization (IWO), Sick Building Syndrome (SBS) and speed and accuracy of simple reaction time was studied. The level of neuroticism was assessed by Cornell Index (C.I.

Sick building syndrome: psychological, somatic, and environmental determinants.

The authors aimed to examine potential relationships between work-related symptoms attributed to sick building syndrome (SBS) and certain psychological, somatic, and environmental factors. The multidisciplinary, cross-sectional study comprised 171 female subjects working in air-conditioned and naturally ventilated nonindustrial office buildings. The authors collected information concerning symptoms related to SBS and made assessments of quality of life by using appropriate questionnaires.

Association of toxic and essential metals with atopy markers and ventilatory lung function in women and men.

The association of age, smoking, alcohol, superoxide dismutase (SOD), glutathione peroxidase (GPx), blood lead (BPb) and cadmium (BCd) levels, and serum levels of copper (SCu), zinc (SZn) and selenium (SSe) with atopic status and ventilatory function was examined in the groups of 166 women and 50 men with no occupational exposure to metals or other xenobiotics. Markers of atopy included serum total IgE, skin prick test (SPT) to common inhalatory allergens, non-specific nasal reactivity (NNR) and non-specific bronchial reactivity (NBR). Parameters of ventilatory function included forced vital capacity (FVC) and forced expiratory volume in the first second (FEV(1)).

A skin prick test, pulmonary function test, histamine challenge test and exercise challenge test (ECT) were performed in all subjects.

[Current views on allergic diseases].

Allergic diseases are an increasing health problem in the industrialised and developed countries especially in children and young adult persons. They are considered diseases of modern civilisation. The reported cumulative prevalence of allergic diseases in childhood of 25-30% includes allergic rhinoconjunctivitis, asthma and dermatitis.

[Allergic disorders of the respiratory system and skin as a public health problem].

The prevalence of allergic diseases is rapidly increasing over the last 40 years, especially in most industrialized countries of the world. Manifestations of allergic diseases are observed in about 35% of the general population. In this paper, the most frequent allergic respiratory and skin diseases are described (rhinitis, asthma, atopic eczema/dermatitis syndrome, contact eczema/dermatitis, urticaria).

The 3 mm skin prick test (SPT) threshold criterion is not reliable for Tyrophagus putrescentiae: the re-evaluation of SPT criterion to dust mites.

Background: The mean wheal diameter >/= 3 mm is the usual criterion for positive skin prick test (SPT) reaction to dust mites. The study assessed the accuracy of this SPT criterion with respect to specific IgE values of above 0.35 kUA/l (+ sIgE).

[Exercise-induced bronchospasm and its prevention].

Exercise-induced bronchospasm (EIB) is a type of nonspecific bronchial hyperreactivity. It affects mostly children and younger adults with asthma (75%-95%) and allergic rhinitis (40%), but it is also found in 3-11% of the nonasthmatic and nonatopic younger population. Pathophysiology of this phenomenon is not clear and there are some attempts to explain it with hyperosmolality of bronchial epithelia, exchange of heat and water (reactive hyperemia) in airways and reflex vagal bronchospasm.

[Outdoor and indoor allergens and the respiratory tract].

This paper gives an overview of common outdoor and indoor allergens which cause sensitisation of the respiratory tract and considers relevant biological and ecological hallmarks and symptoms of allergies. Grass, tree, and weed pollens as well as moulds (Cladosporium and Alternaria species) are a major source of allergens in the outdoor environment whereas mites (Pyroglyphidae, Acaridae, and Glycyphagidae), animals (pets, rodents, and insects), and moulds (Aspergillus, Penicillium, and Mucor species) are a major source in the indoor environment. The paper pays attention to the seasonal, geographical, and climatic influence on the concentration of allergen in the environment.

[Modern environmental and clinical aspects of sensitization to dust mites].

Sensitization to dust mites is in significant increase in the world and is known as independent risk factor for development of bronchial asthma. In this paper, important biological markers and environmental spread of dust mites are described as well as the epidemiology, the most frequent clinical patterns and standard diagnostic procedures of sensitization to dust mites. The importance of the environmental dust mites control is emphasized, particularly as a part of primary and secundary prevention of sensitization to dust mites.

[Sensitivity to latex and other rubber substances--an important occupational risk for health personnel (case report)].

Sensitization to latex and rubber additives has been acknowledged during the last 10 years as a major occupational health problem among health-care workers. In sensitized persons, respiratory and/or skin symptoms may be present. Pathophysiologic mechanisms of senzitisation involve allergic reactions types I and IV (Coombs and Gell).

[Respiratory function and allergic reactions in paper recycling workers].

Respiratory function and allergic reactions were studied in 101 male workers in paper recycling and in 87 nonexposed male control workers. Ventilatory capacity was measured by recording maximum expiratory flow-volume (MEFV) curves with readings on forced vital capacity (FVC), one-second forced expiratory volume (FEV1), and maximum expiratory flows at 50% and the last 25% (FEF50 and FEF25, respectively). Skin prick test with paper dust allergens, some nonoccupational allergens, and total immunoglobulin IgE analysis were used to assess immunological status.
