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
Occupational allergy from exposure to squid has been rarely described, mainly as contact dermatitis or urticaria. Our report presents the first case of occupational asthma, rhinitis, conjunctivitis and contact urticaria to squid in a 33-year-old seafood production worker, with documented increased eosinophilia in the nasal and tear fluids after specific inhalation challenge test (SICT) with squid. IgE-mediated sensitization to squid was confirmed by positive skin prick test and opened skin test with squid extract. SICT demonstrated a direct and significant link between the exposure to squid and the allergic response from the respiratory system and conjunctiva.
This report presents a case of occupational asthma, rhinitis and conjunctivitis to papain in a 50-year-old herbs and spices packer, with documented increased eosinophilia in induced sputum and in the nasal lavage fluids after a specific inhalation challenge test (SICT) and specific nasal challenge test (SNCT) with this enzyme. Immunoglobulin E-mediated (IgE) sensitization to papain was confirmed by positive results of a skin prick test with specific solution. Specific inhalation and nasal challenge tests demonstrated a direct and significant link between the exposure to this protease and the allergic response from the respiratory system. Additionally, the SNCT induced a severe reaction of the conjunctivae and a significant increase in the count of eosinophils in tears, despite the lack of direct contact of the allergen with the conjunctiva.

W badaniu cytologicznym udokumentowano wzrost odsetka eozynofilów w indukowanej plwocinie i popłuczynach nosowych po swoistej próbie prowokacyjnej wziewnej i donosowej z tym enzymem. Zależną od immunoglobuliny E (IgE) nadwrażliwość pacjentki na papainę potwierdzono dodatnimi wynikami punktowych testów skór-nych z roztworem tej proteazy. Wyżej wymienione próby prowokacyjne wykazały istotny związek między ekspozycją na papainę a reakcją alergiczną ze strony układu oddechowego. Ponadto swoista próba prowokacyjna donosowa wywołała wzmożoną reakcję ze strony spojówek i istotny wzrost odsetka eozynofilów we łzach mimo braku bezpośredniego kontaktu alergenu ze spojów-kami. Med.

Fungi belong to common allergens, which can be found both in occupational and non-occupational environment. The aim of the study was to determine the frequency and factors associated with mould allergy among bakers and farmers reporting work-related respiratory symptoms. The study group comprised 117 bakers and 83 farmers reporting work-related respiratory symptoms. Skin prick tests (SPT) with common, fungal and occupational allergens, estimation of serum total IgE level, spirometry, histamine test and specific inhalative challenge test with occupational allergens were performed in all subjects. The prevalence of hypersensitivity to fungal species was higher among farmers (32.5%) than bakers (16.2%). Positive SPT with mould allergens were found among 10.8% farmers and 6.8% bakers with occupational allergy. The fungi allergens giving positive SPT results most frequently were Candida albicans, Levures mélanges, Aspergillus mix. and Charbons cerealiers in both groups. Among mould allergens, hypersensitivity to Aspergillus genus was the most common in farmers and bakers group, while among Saccharomyces - Candida albicans sensitization was the most frequently detected. Mould hypersensitivity is related to occupational respiratory allergy, especially to asthma and rhinitis in farmers, and occupational asthma in bakers. Although sensitization to Saccharomyces was more frequent, similar correlation was not observed.
Background: Tea may be classified as unfermented green, semi-fermented oolong and fermented black. All of these types are derived from Camellia sinensis, the Tea Plant, which contains the low molecular weight (LMW) agent Epigallocatechin gallate (EGCg), probably responsible for allergic reactions. The aim of our study was to asses the work-related allergic symptoms and IgE-mediated sensitivity among black tea packers. Material and Methods: Study groups comprised 26 black tea packers (group 1) and 20 office workers (group 2). A questionnaire, skin prick tests (SPTs) to common allergens and black tea, evaluation of specific IgE (asIgE) to Camellia sinensis and moulds, pre-and post-work-shift spirometry were performed. Results: At least 1 symptom suggesting allergic disease was reported by 85% of the tea packers and 60% of the office workers. The most frequent positive results of SPTs were obtained with moulds (8%). A small decline in FEV 1 (forced expiratory volume in 1 s) after the work shift was observed among tea packers sensitized to moulds. Conclusions: Although specific sensitization to black tea was not observed in our study groups, cough and skin symptoms were significantly more frequently among the tea packers than in office workers. The irritant impact on the airways and the skin of tea dust and/or sensitization to moulds contaminating tea leaves are being suspected.
Occupational Asthma in Female Factory Worker Resulting from Exposure to Savinase in Dishwashing Tablets—A Case Study: Agnieszka LIPIŃSKA‐OJRZANOWSKA, et al. Department of Occupational Diseases, Nofer Institute of Occupational Medicine, Poland— 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 readymade 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 as IgE 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.
The etiology of cancer is multifactorial. Malignant tumors caused by factors occurring in the work environment, classified as carcinogenic in humans, can be recognized as an occupational disease. Analysis of epidemiological data indicates a significant underestimation of occupational cancer, mainly due to long latency period of these diseases. This publication provides guidance to certify occupational etiology of malignant tumors, based on the reviews of existing legislation and medical literature, as well as on the experience of their authors. The publication presents the epidemiology of cancers, including occupational cancers, risk factors, occupational carcinogens and presents the principles of occupational cancer certification.
