RESUMO

BACKGROUND: Every year in Poland almost 5 million prophylactic examinations (PEs) are carried out by occupational medicine specialists (OMPs) among workers, for the purposes envisaged in the Polish Labour Code. The aim of this study was to collect workers' opinions on the possible extension of these check-ups in the field of prophylaxis and prevention of civilization diseases (CivDs), focusing also on the "healthy lifestyle" recommendations. MATERIAL AND METHODS: The study group comprised 325 employees who filled out an anonymous questionnaire containing questions about the possible extension of the PE scope for CivD and cancer prophylaxis. During medical check-ups, evaluation of the incidental glucose (IG) and total cholesterol (TCh) levels, waist circumference measurement and electrocardiography (ECG) were proposed. The respondents were asked about the most interesting issues for discussing with OMPs. RESULTS: Screening tests for some cancers (69.5%) and risk factors for CivDs (61.5%) were indicated as the most interesting topics to discuss with OMPs. The possibility for evaluating the levels of IG and TCh during PEs was approved by approx. 94.8% and 95.3% of the respondents, respectively. Almost 96% accepted having ECG and 80% agreed to waist circumference measurement. As many as 89.5% of the respondents supported the idea of organizing physical activities at their workplaces, and 77.8% were eager to learn about "healthy lifestyles" during training sessions conducted at their workplaces. CONCLUSIONS: Restricting the aim of PEs just to certifying the ability to work, or identifying certain medical contraindications, means losing a chance for implementing the prophylaxis and prevention of diseases' development among active working subjects. The kinds of activities proposed by the authors of this publication have been approved by the employees. Med Pr. 2019;70(4):425-33.

RESUMO

OBJECTIVES: Manicurists are exposed to various chemicals in nail and skin care products and may develop ocular, nasal, respiratory or skin adverse reactions to them. To investigate the occurrence of ocular, nasal, respiratory and skin problems among manicurists and to identify their causal factors, particularly allergic etiology and occupational origin. MATERIAL AND METHODS: Manicurists employed in beauty salons in the central region of Poland were invited to fill in the questionnaire and undergo medical examination, skin prick tests with common aeroallergens, patch tests with European Baseline Series and (Meth)Acrylates Series-Nails and spirometry. RESULTS: In the questionnaire adverse nasal symptoms were reported by 70%, ocular - by 58%, respiratory - by 42%, hand eczema - by 43% of manicurists. In the medical interview, the frequency of those complaints was lower: nasal ones - 41%, ocular - 24%, cough - 18%, hand skin dryness - 20%, hand eczema - 6%. Cough and hand skin dryness occurred significantly more frequently than in the case of controls. Contact allergy was found for 41% of manicurists and 35% of controls. The prevalence of nickel sensitization was high in both groups (38% and 27%, respectively). Only 3 manicurists reacted to (meth)acrylates. The frequency of atopic diseases was similar in compared groups. Irritant nasal and respiratory reactions were significantly more prevalent among manicurists (nasal - 18% vs. 2%, p < 0.01; respiratory - 18% vs. 1%, p < 0.001). Work-related nasal irritant reactions were finally diagnosed for 19%, ocular ones - for 13%, respiratory - for 18% and within hand skin - for 23% of manicurists. CONCLUSIONS: The frequency of workattributed irritant mucosal and skin symptoms among manicurists is high. Exposure to acrylates is an important source of mucosal irritant reactions while occlusive gloves cause irritation of hand skin. The prevalence of nickel allergy among Polish females is high.

RESUMO

BACKGROUND: Hairdressers are occupationally exposed to many allergenic and irritating substances. Additionally, hairdressing apprentices are exposed to the same allergens as professional hairdressers, due to the fact that vocational training starts in the beginning of the education. This study was undertaken to investigate early occurrence of sensitization to occupational allergens in hairdressing apprentices before the onset of the vocational training. MATERIAL AND METHODS: Three hundred and seven hairdressing apprentices were assessed using a questionnaire and skin prick tests (SPTs) to common and occupational allergens. The level of total and serum specific immunoglobulin E (IgE) to occupational allergens was evaluated and spirometry was performed. RESULTS: At least one skin and/or respiratory and/or conjunctival symptom was reported by 29.9% of subjects. Among subjects with at least one symptom, 28.2% of them were atopic whereas among 43.4% of them total IgE level was elevated. Atopy was found in 20% cases. In the case of one apprentice, positive SPT for paraphenylenediamine was found. Nearly 33% of apprentices had elevated total IgE level and 5 of them had specific IgE for occupational allergens. CONCLUSIONS: The study revealed that hairdressing apprentices might be sensitized to occupational allergens even before the beginning of vocational training, due to prior non-professional exposure to hairdressing agents. Furthermore, many of them report skin, respiratory and conjunctival symptoms, often connected with chronic disease diagnosis. Thus, candidates for hairdressers should be examined thoroughly before the start of the education and tests for allergy to hairdressing substances are indicated. Med Pr 2016;67(5):567-575.

RESUMO

OBJECTIVES: The aim of the study was to evaluate health effects of occupational exposure to diisocyanates (DIC) among polyurethane foam products factory workers. MATERIAL AND METHODS: Thirty workers had a physical examination, skin prick tests with common allergens, allergen-specific immunoglobulin E (IgE) antibodies to diisocyanates and pulmonary function tests. Concentrations of selected isocyanates in the workplace air samples as well as concentration of their metabolites in the urine samples collected from the workers of the plant were determined. RESULTS: The most frequent work-related symptoms reported by the examined subjects were rhinitis and skin symptoms. Sensitization to at least 1 common allergen was noted in 26.7% of the subjects. Spirometry changes of bronchial obstruction of a mild degree was observed in 5 workers. The specific IgE antibodies to toluene diisocyanate (TDI) and 4,4'-methylenebis(phenyl isocyanate) (MDI) were not detected in any of the patients' serum. Cellular profiles of the collected induced sputum (ISP) did not reveal any abnormalities. Air concentrations of TDI isomers ranged 0.2-58.9 µg/m3 and in 7 cases they exceeded the Combined Exposure Index (CEI) value for those compounds. Concentrations of TDI metabolites in post-shift urine samples were significantly higher than in the case of pre-shift urine samples and in 6 cases they exceeded the British Biological Monitoring Guidance Value (BMGV - 1 µmol amine/mol creatinine). We didn't find a correlation between urinary concentrations of TDI, concentrations in the air and concentrations of toluenediamine (TDA) in the post shift urine samples. Lack of such a correlation may be an effect of the respiratory protective equipment use. CONCLUSIONS: Determination of specific IgE in serum is not sensitive enough to serve as a biomarker. Estimation of concentrations of diisocyanate metabolites in urine samples and the presence of work-related allergic symptoms seem to be an adequate method for occupational exposure monitoring of DIC, which may help to determine workers at risk as well as to recognize hazardous workplaces.

RESUMO

OBJECTIVES: About 5-10% of asthmatics do not respond well to standard treatment plan. Occupational exposure may be one of the factors that can be linked with treatment failure. The aim of the study was to assess the prevalence of work-related asthma (WRA) among adult asthmatics under follow up in an outpatient allergy clinic and to create a useful tool for detecting individuals with possible WRA. MATERIAL AND METHODS: Preliminary 5-question questionnaire designed to recognize WRA was presented to 300 asthmatics. All patients with positive preliminary verification along with 50 subjects from control group were asked to fill up a detailed questionnaire. The WRA was diagnosed by positive match for asthma symptoms in combination with workplace exposure indicated in the detailed WRA questionnaire followed by confirmation of each WRA case by detailed exposure analysis. RESULTS: Work-related asthma was recognized in 63 subjects (21% of study group). The preliminary questionnaire has 76.9% sensitivity and 94% specificity in recognition of WRA. Occupational exposure to irritants is a risk factor of WRA recognition (relative risk (RR) = 2.09 (1.44:3.03)). Working in exposure-free environment is a factor against WRA recognition (RR = 0.38 (0.24:0.61)). Among subjects with work-related asthma, the uncontrolled course of the disease is significantly more frequent (p = 0.012). Subjects with WRA more often report sickness absenteeism due to asthma than those without WRA (9.6% vs. 3.2%, respectively), but the observed differences did not reach the statistical significance. CONCLUSIONS: Short 5-question questionnaire seems to be a promising tool to detect individuals with possible work-related asthma in the outpatient setting for further evaluation and additional attention.

RESUMO

OBJECTIVES: Several studies, mostly based on questionnaire-derived data, have shown an increased risk of allergic diseases, especially asthma, among cleaners. The risk factors and etiological mechanisms are still being investigated. Occupational exposure to various chemical and biological agents may induce specific sensitization and/or irritant effects. The aim of our study was to estimate the prevalence of work-related symptoms suggesting the presence of allergic disease reported by cleaners, and to relate them to the results of commercially available and standardized objective tests used for screening detection of occupational sensitization and chronic respiratory disorders. MATERIAL AND METHODS: A cross-sectional study was performed among 142 Polish workers of cleaning service in their workplaces. A detailed questionnaire, skin prick tests to common allergens and chemicals used by these workers for cleaning purposes (chloramine T, chlorhexidine, formaldehyde, glutaraldehyde, benzalconium chloride), total and specific serum IgE antibodies to disinfectants and rest spirometry were performed in all the subjects. RESULTS: Fifty nine percent of all the subjects declared occurrence of at least 1 symptom suggesting allergic ailment during cleaning activities at work. Skin prick tests and specific serum IgE antibodies to disinfectants were negative in all the subjects. In 8 cases wheezing was detected during auscultation, but only in 5 of them obstructive pattern in rest spirometry was found. CONCLUSIONS: Occupational allergic causation of symptoms among cleaners could be less likely than work-related symptoms associated with exacerbations of new-onset or pre-existing respiratory diseases. Therefore, in this group of workers, mainly the non-specific irritant impact of chemicals on airways should be taken into consideration.

RESUMO

OBJECTIVES: To evaluate sensitization to chemicals present in work environment after an outbreak of contact dermatitis in workers of vehicle equipment factory, exposed to polyurethane foam, based on 4,4'-diphenylmethane diisocyanate (MDI). MATERIAL AND METHODS: From among 300 employees, 21 individuals reporting work-related skin and/or respiratory tract symptoms underwent clinical examination, patch testing, skin prick tests, spirometry and MDI sIgE measurement in serum. Patch tests included isocyanates series, selected rubber additives, metals, fragrances, preservatives, and an antiadhesive agent. RESULTS: Clinical examination revealed current eczema in the area of hands and/or forearms in 10 workers. Positive patch test reactions were found in 10 individuals, the most frequent to diaminodiphenylmethane and 4-phenylenediamine (7 persons). Reactions to an antiadhesive agent were assessed as irritant (5 workers). Except for sensitization to common aeroallergens, no significant abnormalities were found in the remaining tests. Occupational allergic contact dermatitis was diagnosed in 7 workers, irritant contact dermatitis in 10 and coexisiting allergic and irritant contact dermatitis in 3 workers. CONCLUSIONS: In workers manufacturing products from polyurethane foam, attention should be paid to the risk of developing contact dermatitis. Skin problems in our study group were attributable probably to insufficient protection of the skin.

RESUMO

Highly reactive, low-molecular-weight diisocyanates (DIC) are the most commonly identified cause of occupational asthma (OA). Animal/clinical studies of DIC asthma have been more limited compared with atopic asthma, and an understanding of DIC pathogenesis is less clear. The aim of this study was to investigate in a mouse model, toluene diisocyanate (TDI, as 2,4-TDI isomer)-induced inflammatory reactions/cytokine profile changes in the lungs and accompanying changes in lymph node lymphocyte sub-populations. The study used female BALB/cJ/Han/IMP mice that were exposed first intra-nasally and then in an inhalation chamber to TDI or air. After the final exposure, bronchoalveolar lavage fluid (BALF) was collected and changes induced in inflammatory cell composition, levels of key cytokines (i.e. IL-4, TNFα, IFNγ), and lymphocyte sub-population profiles within auricular lymph nodes, were evaluated. Total number of cells in the BALF of treated mice was significantly higher than in control mice BALF. There was also a significant increase in BALF neutrophil and eosinophil levels with TDI mice compared to in controls; lymphocyte and macrophage numbers did not significantly differ. A significant increase in BALF levels of TNFα and IFNγ was also noted in mice exposed to TDI relative to levels in controls. BALF IL-4 levels were also increased, but the change from control was not significant. Lastly, the levels/percentages of CD3(+)CD4(+) (T-helper [TH]) lymphocytes significantly increased in the lymph nodes of TDI-exposed groups while those of the CD3(+)CD8(+) cells decreased as compared to in control mice. These studies, the first to assess TDI-induced changes in levels of three key cytokines in BALF in conjunction with changes in local lymph nodes following first an intra-nasal and then a general inhalation exposure to a low-level of TDI, confirm that TDI inhalation induces a pathology manifested by airway inflammation, TH cell-derived cytokine production, and shifts in lymph node lymphocytes sub-populations toward increases in TH cells.

RESUMO

BACKGROUND: Nurses are prone to develop hand eczema due to occupational exposure to irritants, including wet work. The aim of the study was to evaluate the impact of wet work on selected skin properties, reflecting epidermal barrier function--transepidermal water loss (TEWL) and stratum corneum hydration--and additionally skin viscoelasticity, in nurses. MATERIAL AND METHODS: Study subjects included 90 nurses employed in hospital wards. Measurements were carried out within the dorsal aspect of the dominant hand, using a Cutometer MPA 580 equipped with Tewameter TM 300 and Corneometer CM 825 (Courage & Khazaka, Germany) probes. Examina- tions took place on hospital premises. Similar measurements were performed in the control group of females non-exposed to irritants. RESULTS: In the examined group of nurses, mean TEWL was 15.5 g/h/m2 and was higher than in the control group (12.99 g/h/m2). After rejecting the extreme results, the difference between the groups proved to be statistically significant (p < 0.05). The mean value of stratum corneum hydration was lower in the examined group (37.915) compared with the control group (40.05), but the difference was not sta tistically significant. Also results of viscoelasticity assessment showed no significant differences between studied groups. CONCLUSIONS: The results of the assessment of skin biophysical properties show that wet work exerts a moderately adverse impact on skin condition. A higher TEWL value and a lower stratum corneum hydration in workers exposed to irritants reflect an adverse impact of these factors on the epidermal barrier function.

RESUMO

OBJECTIVES: Savinase is one of the endopeptidases widely used in washing detergents. Its ability to cause respiratory allergy has been known. Up to now, most cases of occupational asthma (OA) to savinase have been described among workers involved in the manufacture of laundry detergents. We present a case study of 51-year-old female worker of a dishwashing tablets factory, who had been packaging ready-made tablets into foil wrappers for 4 years and developed respiratory symptoms, such as cough, dyspnoea and wheezing. METHODS: A number of clinical procedures were performed, including the clinical examination, routine laboratory tests, evaluation of total and allergen-specific serum IgE (asIgE) to enzymes, skin prick tests for common allergens, rest spirometry, inhalation methacholine challenge test and a single-blind, placebo-controlled specific inhalation challenge test (SICT) with dishwashing tablets. RESULTS: Clinical findings and results of routine laboratory tests were within normal limits. Baseline nonspecific bronchial hyperreactivity was revealed. In patient's serum blood we found significantly elevated asIgE to savinase. Decline of FEV1 and PEF in late phase of asthmatic reaction was observed during the specific challenge test. The patient reported chest tightness between 5-12 hours after exposure to dishwashing tablet ingredients. Cytological assessment of an induced sputum revealed increase in the percentage of eosinophils 24 hours after specific challenge in comparison to values noted before the SICT. CONCLUSIONS: Positive clinical response to the challenge confirmed in objective method tests validated the diagnosis of OA.

RESUMO

In recent years occupational skin and respiratory diseases have been more and more frequently diagnosed in small production and service enterprises. The awareness of occupational exposure and its possible health effects among their workers and employers is not sufficient. Beauty salons, in addition to hairdressers and beauticians, frequently employ manicurists and pedicurists. The workers often happen to perform various activities interchangeably. the health status of beauty salons workers has rarely been assessed. The most numerous reports concern hairdressers. In this occupational group, the occurrence of skin lesions induced by wet work and frequent allergy to metals, hair dyes and bleaches and perm solutions has been emphasized, while information about health hazards for being a manicurist or pedicurist in beauty salons is seldom reported. The aim of this paper is to present professional activities (manicure and pedicure, methods of nail stylization), occupational exposure and literature data on work-related adverse health effects in manicurists and pedicurists. Wet work and exposure to solvents, fragrances, resins, metals, gum, detergents may cause skin disorders (contact dermatitis, urticaria, angioedema, photodermatoses), conjunctivitis, anaphylaxis, respiratory tract diseases, including asthma. The discussed occupations are also associated with the increased incidence of bacterial (particularly purulent), viral and fungal infections and cancer.

RESUMO

OBJECTIVES: Diisocyanates (DIC) are highly reactive, low-molecular-weight chemicals which are the leading cause of occupational asthma (OA). The aim of the study was to analyze certain aspects of the pathogenesis of allergic inflammation in the airways induced by toluene diisocyanate (TDI) in an experimental model in mice. MATERIALS AND METHODS: The experiment was carried out on 50 female BALB/cJ/Han/IMP mice, which were exposed by inhalation (intranasal and in the inhalation chamber) to toluene diisocyanate (2,4-TDI). After the experiment, the bronchoalveolar lavage fluid (BALF) was collected from the animals, and the composition of the induced inflammatory cells, and the concentrations of certain cytokines (IL-4, IL-5, TNF-α) were evaluated. RESULTS: The total number of cells in BALF of the examined group of mice was significantly higher compared to the control mice. There was also a significant increase in neutrophils and eosinophils in the study group compared to the controls. The number of lymphocytes and macrophages did not differ significantly between the two groups. A statistically significant increase in the level of TNF-α was shown to occur in the group exposed to toluene diisocyanate in comparison to the control group. The concentration of IL-4 increased in the study group, compared to the control one, but the differences did not reach the level of significance, p > 0.05. Such difference was not observed for IL-5. CONCLUSIONS: We developed a murine model of TDI-induced asthma which caused the influx of inflammatory cells like eosinophils and neutrophils in the bronchoalveolar lavage fluid (BALF) in the TDI-treated mice. The increase of the concentration of some proinflammatory cytokines (TNF-α, IL-4) in BALF from the exposed mice was also observed.

RESUMO

Diisocyanates are currently the most common cause of occupational asthma in industrialized countries, where its prevalence ranges from less than 5% to 15%. They are mainly used in the production of polyurethane foam, plastic packagings, laminates and polyurethane paints. The diagnosis of diisocyanate asthma is often problematic due to the lack of simple diagnostic or screening tests, uncertainty of underlying mechanisms, and a multitude of other potential occupational and environmental causes of asthma. At present, only a specific standardized challenge test with diisocyanates in concentrations not exceeding the adopted hygiene standards has been found to show a real diagnostic value. The diisocyanate-inducedsensitization, is associated with the recruitment of CD4 T lymphocytes to the lungs and the production of Th2-type cytokines, including IL-4, IL-5 and IL-13. However, clinical studies have suggested that an immunological response to diisocyanates may involve both Th1 and Th2 cells. The development of animal models has been instrumental in furthering the understanding of the pathogenesis of many diseases, including bronchial asthma. Murine models of diisocyanate-induced asthma have proved to be the most useful. Mouse models offer distinct advantages of a better-defined genome than that of guinea pigs or rats and the availability of antibody reagents and transgenic strains to investigate detailed mechanistic pathways. A better understanding of the immunopathogenesis of diisocyanate asthma will hopefully lead to early markers of sensitization and asthma, as well as to a profound comprehension of exposure and host risk factors, both of them should greatly facilitate the development of much-needed diagnostic and preventive strategies for diisocyanate asthma.

RESUMO

OBJECTIVES: The aim of this study was to evaluate the coexisting factors and usefulness of diagnostic methods in metal-induced asthma in Polish welders. MATERIALS AND METHODS: Examination of 50 welders occupationally exposed to metals and with suspicion of metal-induced asthma (group A), 100 welders occupationally exposed to metals but without suspicion of metal-induced asthma (group B), and two control groups (10 patients with atopic asthma and 10 healthy subjects) was carried out. Questionnaire survey, clinical examination, skin prick tests to common aeroallergens and metal salts, rest spirometry tests, X-ray, metacholine challenge and a single-blind, placebo controlled specific inhalation challenge tests with metals (or work-like conditions challenge tests) were performed. RESULTS: In group A--in 9 cases we obtained positive results of specific inhalation challenge tests with metals (in 3 cases with nickel, in 4 cases with chromium, in 1 case with cobalt and in 1 case with manganese). Nine cases of metal-induced occupational asthma were recognized. In group B--only in one case we obtained positive results of work-like conditions challenge test (clinical and spirometry changes, eosinophil influx in induced sputum), which confirmed the diagnosis of occupational asthma. In most of examined welders (62%), pulmonary changes in chest X-ray images were noted. The statistical analysis revealed that working as a welder for more than 10 years is the coexisting factor of presence of chest X-ray changes (p- or q-type nodular changes or interstitial changes). Positive results of skin prick tests with metal salts were the coexisting factors of occupational asthma due to metals among examined group of welders. CONCLUSIONS: Specific inhalation challenge plays the key role in diagnostics of metal-induced asthma in welders. Pulmonary changes in chest X-ray were found in a significant percentage of examined welders.

RESUMO

Para-phenylenediamine (PPD) can induce immediate or - more often - delayed hypersensitivity. We report the case of 48-year old female admitted to the out-patient allergy clinic a day after her visit in a beauty parlour, where she had her eyelashes and eyebrows dyed with henna. Physical examination revealed prominent edema of the upper part of the face including forehead, cheeks and eyes causing severe narrowing of the palpebral chink. Skin prick tests (SPT) with common allergens were positive for Dermatophagoides pteronyssinus, Dermatophagoides farinae and moulds, while the SPT with PPD was negative. Patch test to PPD was positive. Further investigations revealed eosinophilia in the tear fluid. To our knowledge, this is the first case of PPD-induced contact blepharoconjunctivitis (CB) with concomitant increased eosinophilia in the tear fluid.

RESUMO

Recently, infectious diseases have been found to be the most frequent among occupational diseases. Borreliosis, the most common among them, as well as tick-borne encephalitis is transmitted by ticks. Recognition of occupational etiology of such diseases is possible only when the relationship between the infection, occupational exposure and performed work is proved. A case report of a forest worker with borreliosis coexisting with tick-borne encephalitis is presented. Despite nonconcurrent recognition of both diseases it was highly possible that contagion took place at the same time or at a very short time interval. Despite high prevalence of tick-borne diseases, occupational etiology of these two infectious diseases in one patient is very rarely recognized.

RESUMO

BACKGROUND: The aim of the study was to analyze the data obtained during the diagnostic process and their real values in the final diagnosis of patients exposed to diisocyanates amd suspected of occupational allergic disease of the respiratory system The patients have been hospitalized in the Nofer Institute of Occupational Medicine over recent 11 years. MATERIAL AND METHODS: In 1999-2009 we hospitalized 37 patients exposed to diisocyanates and suspected of occupational asthma. RESULTS: Test results of 37 patients were analyzed. The patients were divided into three groups of those with diagnosed occupational asthma, with diagnosed non-occupational asthma and those without any allergic airway disease. 40.0% of patients with occupational asthma, 64.3% of patients with non-occupational asthma and 15.4% of patients without any allergic disease were sensitized to at least one of common allergens. We did not find any specific IgE to diisocyanates. Specific challenge tests were performed in all the 37 subjects. We observed positive results of SIT with diisocyanates in 10 patients. CONCLUSIONS: Only specific challenge test with diisocyanates showed the real diagnostic value in case of a 7.5-year cessation of exposure. Determination of serum specific IgE to diisocyanates does not seem to be of clinical value in the diagnosis of diisocyanate-induced asthma in case of a 7.5 year cessation of exposure. Atopy is not the risk factor in diisocyanate-induced asthma.

RESUMO

BACKGROUND: The aim of the study was to evaluate the prevalence of hypersensitivity to fungi among art conservators and museum workers. MATERIAL AND METHODS: 200 art conservators and museum workers were examined using a questionnaire, skin prick tests to common mite and fungal allergens. Moreover, the level of serum specific IgE to fungi were evaluated, and rest spirometry was performed in all subjects. RESULTS: The most frequent symptoms reported by the examined subjects were: rhinitis (N=132, 66%), conjunctivitis (N=137, 68.5%), skin symptoms (N=108, 54%), chronic cough (N=52, 26%) and dyspnoea (N=56, 28%). 69 subjects (34.5%) developed symptoms during work with objects contaminated by biological agents. 90 art conservators and museum workers (46.2%) were sensitized to at least one of common allergens, and 47 (23.5%) to fungal allergens. Specific IgE to fungi were found in 14 (7%) cases, most frequently to Candida albicans and Penicillium notatum, Cladosporium herbarum, Aspergillus fumigatus, Alternaria alternata. CONCLUSIONS: 85% of art conservators and museum workers reported allergic symptoms. Cladosporium, Alternaria and Yeats were the species that played the most important role in the development of fungal hypersensitivity among art conservators and museum workers. Duration of occupational exposure of more than 5 years, presence of domestic animals especially a cat at home, elevated total IgE level, allergic rhinitis and skin hyperreactivity to common allergens (grass pollens and mites) are significant risk factors for the development of hypersensitivity to fungi among art conservators and museum workers.
