Objectives: Exposure to latex allergens in latex gloves can cause occupational health problems in nurses, yet latex gloves are still widely used in Thai hospitals. Therefore, we conducted a study to determine the prevalence of latex sensitization in nurses and identify risk factors associated with sensitization. Methods: A questionnaire, providing information on personal characteristics, ill-health, working conditions and symptoms related to latex product use, was administered to 363 female nurses working in two tertiary hospitals in southern Thailand. Latex sensitization was confirmed using a solid phase immunoassay to detect anti-latex IgE antibodies. Total glove protein levels were determined by using a modified Lowry method and latex aeroallergens by a competitive inhibition immunoassay. Results: The overall prevalence of latex sensitization was 4.4%. Respiratory symptoms related to latex glove use were significantly associated with latex sensitization (OR = 5.5, 95% CI: 1.57-19). Total glove protein levels ranged 87.8-250.8 μg protein/dm². The prevalence of latex sensiti- zation was higher (6.6% vs. 2.2%) in the hospital where gloves with higher protein levels (82-438 μg/g vs. 86-170 μg/g) were used. Furthermore, latex sensitization prevalence increased from 3% to 5% with increased average departmental aeroallergen concentrations. Conclusions: Latex sensitization prevalence in Thai nurses was higher than previously reported. Respiratory exposure seems to play an important role, in addition to dermal exposure. If latex gloves cannot be replaced by non-latex alternatives, replacement with gloves with lower protein content should be considered.

Contact dermatitis is a major problem in the healthcare environment and in other sectors. Healthcare professionals may be exposed to a large number of chemical agents, including the accelerators for rubber vulcanization process. The prevalence of allergic contact dermatitis among operators in the sector ranges 13–30%. This paper describes the case of a 46-year-old male cardiac surgeon affected by a severe skin reaction localized on the face in the absence of hand dermatitis, presumably resulting from the use of a surgical patch applied to the face. Patch tests were performed and the result was negative for latex and positive (+++) for thiuram mix. A thiuram-free tape was prescribed and the operator’s dermatitis improved significantly. Thus, it would be very important to pay attention to skin disorders in health workers and thiuram as an occupational allergen. Med Pr. 2019;70(1):121–4

Background Preservatives present in cosmetics and other industrial products can cause allergic contact dermatitis. The aim of the study was to assess the frequency of allergy to selected preservatives in consecutive patients examined due to contact dermatitis in the Nofer Institute of Occupational Medicine, Łódź, and to establish whether individuals sensitized to formaldehyde react simultaneously to formaldehyde releasers. Material and Methods A group of 405 patients (308 females and 97 males) was examined in 2011–2013. In all participants patch tests with a series of 13 preservatives (paraben mix, formaldehyde, Quaternium 15, chloromethylisothiazolinone/methylisothiazolinone mix, methyldibromoglutaronitrile, diazolidinyl urea, imidazolidinyl urea, DMDM hydantoin, 2-bromo-2-nitropropane-1,3-diol, iodopropynyl butylcarbamate, benzalkonium chloride, sodium metabisulfite, produced by Chemotechnique Diagnostics, Sweden) were performed. Results Of the 405 patients 74 (including 52 females) showed positive results of patch tests. Contact allergy to at least 1 preservative was noted in 47 (11.6%) patients, including 34 (11%) females and 13 (13.4%) males. Methylisothiazolinone proved to be the most frequent sensitizer – 4.7% (5.2% females, 3.1% males) while parabens, 2-bromo-2-nitropropane-1,3-diol and imidazolidinyl urea (0.2%) were found to be the least frequent. Fourteen (3.4%) participants, 10 women and 4 men, were allergic to formaldehyde and/or formaldehyde releasers. In 11 (78.6%) of them monovalent hypersensitivity was observed. In 13 (3.2% of the examined group) patients allergy to preservatives might have been of occupational origin. Conclusions Preservatives, particularly isothiazolinones, are significant causal factors of allergic contact dermatitis, including occupational cases. Individuals sensitized to formaldehyde may react simultaneously to formaldehyde releasers, however, such reactions are relatively rare. Med Pr 2015;66(3):327–332

Wstęp Konserwanty zawarte w kosmetykach i wielu innych produktach przemysłowych mogą być przyczyną alergicznego kontaktowego zapalenia skóry. Celem pracy było określenie częstości uczulenia na wybrane konserwanty u kolejnych pacjentów Instytutu Medycyny Pracy im. prof. J. Nofera w Łodzi diagnozowanych z powodu kontaktowego zapalenia skóry oraz ustalenie, czy osoby uczulone na formaldehyd reagują jednocześnie na donory formaldehydu. Materiał i metody U 405 osób (308 kobiet, 97 mężczyzn), diagnozowanych w latach 2011–2013, przeprowadzono serię testów płatkowych z 13 środkami konserwującymi (mieszanina parabenów, formaldehyd, Quaternium 15, mieszanina chlorometyloizotiazolinon/metyloizotiazolinon, metyloizotiazolinon, metylodibromo- glutaronitryl, diazolinydylomocznik, imidazolidynylomocznik, DMDM hydantoina, 2-bromo-2-nitropropano-1,3-diol, butylokarbaminian jodopropynylu, chlorek benzalkonium, pirosiarczan sodowy – prod. Chemotechnique Diagnostics, Szwecja). Wyniki U 405 pacjentów stwierdzono 74 dodatnie wyniki testów płatkowych, w tym 52 u kobiet. Uczulenie na przynajmniej jeden z badanych konserwantów zaobserwowano u 47 osób (11,6%), w tym 34 kobiet (11%) i 13 mężczyzn (13,4%). Najczęściej uczulał metyloizotiazolinon (4,7%, w tym 5,2% kobiet, 3,1% mężczyzn), a najrzadziej parabeny, 2-bromo-2-nitropropano-1,3-diol i imidazolidynylomocznik (0,2%). Czternaście osób (3,4%), w tym 10 kobiet (3,2%) i 4 mężczyzn (4,1%), było uczulonych na formaldehyd lub/i donory formaldehydu. Aż u 11 z nich (78,6%) uczulenie miało charakter jednoważny. U 13 osób (3,2% ogółu badanych) uczulenie na konserwanty mogło mieć charakter zawodowy. Wnioski Środki konserwujące, szczególnie pochodne izotiazolinonu, są istotnymi czynnikami przyczynowymi alergicznego kontaktowego zapalenia skóry, w tym o pochodzeniu zawodowym. Osoby uczulone na formaldehyd mogą reagować jednocześnie na niektóre donory formaldehydu, ale reakcja ta zachodzi stosunkowo rzadko. Med. Pr. 2015;66(3):327–332
