RESUMO
BACKGROUND: Opioid-manufacturing facility workers are at risk of developing occupational contact dermatitis. OBJECTIVES: To describe the causes of occupational allergic contact dermatitis caused by opioids in an opioid-manufacturing facility. MATERIALS AND METHODS: A retrospective review was performed of patients assessed at the Occupational Dermatology Clinic in Melbourne, Australia from 2004 to 2017. RESULTS: Fifteen workers from an opioid-manufacturing facility were assessed in our clinic over a period of 14 years. Of these, 11 individuals were diagnosed with occupational allergic contact dermatitis caused by opioids, with seven reacting to thebaine, five to morphine, four to norhydroxymorphinone, two to codeine, and two to oripavine. Two people were suspected of having immediate hypersensitivity reactions to opioids, including one who also had allergic contact dermatitis. Two patients were diagnosed with urticaria, aggravated at work. One patient was diagnosed with a non-occupational rash. CONCLUSIONS: We report a case series of workers with allergic contact dermatitis caused by opioids in a manufacturing facility. With greater awareness, including implementation of an educational programme and improved skin protection, the number of cases declined over time. Interestingly, norhydroxymorphinone had not been reported as an allergen before. Further testing is required to establish optimal patch test concentrations of all opiates.

BACKGROUND: Lavender is commonly used in aromatherapy and in a broad range of personal and household products. It has been identified as a contact sensitizer, and has been reported to cause allergic contact dermatitis (ACD). OBJECTIVES: To report our experience with contact allergy and ACD caused by lavender, and to raise awareness of lavender as a potential contact allergen. METHOD: A retrospective database review was performed of patients attending patch testing clinics at the Skin and Cancer Foundation, Victoria, Australia, from January 1, 1993 to December 31, 2017. RESULTS: Among the 2178 patients patch tested with lavender over this period, a total of 58 positive reactions were recorded in 49 individuals, giving a positive patch test prevalence for patients tested with lavender of 2.2%. Twenty-seven patients were diagnosed with ACD. The most common sources of exposure to lavender were personal care products and essential oils. Of the patients with ACD, 74% were tested with lavender absolute, with positive results in 90% of cases. CONCLUSION: Lavender is an uncommon cause of ACD but is important to consider, given the potential for exposure through the use of personal care items and essential oils.

Although wool is commonly believed to cause irritant (non-immune) and hypersensitivity (immune) cutaneous reactions, the evidence basis for this belief and its validity for modern garments have not been critically examined. Publications from the last 100 years, using MEDLINE and Google Scholar, were analysed for evidence that wool causes cutaneous reactions, both immune-mediated (atopic dermatitis exacerbation, contact urticaria, allergic contact dermatitis) and non-immune-mediated (irritant contact dermatitis, itch). Secondary aims of this paper were to examine evidence that lanolin and textile-processing additives (formaldehyde, chromium) cause cutaneous reactions in the context of modern wool-processing techniques. Current evidence does not suggest that wool-fibre is a cutaneous allergen. Furthermore, contact allergy from lanolin, chromium and formaldehyde is highly unlikely with modern wool garments. Cutaneous irritation from wool relates to high fibre diameters (≥ 30-32 µm). Superfine and ultrafine Merino wool do not activate sufficient c-fibres to cause itch, are well tolerated and may benefit eczema management.

BACKGROUND: Healthcare workers (HCWs) are at risk of developing occupational skin disease (OSD). OBJECTIVES: To ascertain the causes of OSD in Australian HCWs in a tertiary referral clinic. METHODS: A retrospective review was performed of patients assessed at the Occupational Dermatology Clinic in Melbourne from 1993 to 2014. RESULTS: Of 685 HCWs assessed in the clinic over a period of 22 years, 555 (81.0%) were diagnosed with OSD. The most common diagnosis was irritant contact dermatitis (ICD) (79.1%), followed by allergic contact dermatitis (ACD) (49.7%). Natural rubber latex allergy was also relatively frequent (13.0%). The major substances causing ACD were rubber glove chemicals (thiuram mix and tetraethylthiuram disulfide), preservatives (formaldehyde, formaldehyde releasers, and isothiazolinones), excipients in hand cleansers, which are hard-to-avoid weak allergens, and antiseptics. ACD caused by commercial hand cleansers occurred more frequently than ACD caused by alcohol-based hand rubs (ABHRs). Occupational ICD was mostly caused by water/wet work and hand cleansers, and environmental irritants such as heat and sweating. CONCLUSIONS: Understanding the causes of OSD in HCWs is important in order to develop strategies for prevention. We suggest that skin care advice should be incorporated into hand hygiene education. The use of ABHRs should be encouraged, weak allergens in skin cleansers should be substituted, and accelerator-free gloves should be recommended for HCWs with OSD.

An alarming increase in contact allergy to methylisothiazolinone (MI) has been noted worldwide. Airborne exposure to MI in paint is an acknowledged occupational hazard. We present the first Australian report of airborne allergic contact dermatitis (ACD) following exposure to wall paint containing MI.
RESUMO
OBJECTIVES: To describe the characteristics of patients with occupational skin disease (OSD) in a tertiary referral clinic in Victoria, Australia. METHODS: A retrospective review was conducted of records from patients seen at the Occupational Dermatology Clinic in Melbourne, Australia between 1 January 1993 and 31 December 2010. RESULTS: Of the 2894 people assessed in the clinic during the 18-year period, 44% were women and 56% were men. In all, 2177 (75%) were diagnosed with occupational skin disease (OSD). Of the patients with a work-related skin condition, 45% (n = 979) were considered to be atopic. The most common diagnosis in those with OSD was irritant contact dermatitis (ICD) (44%), followed by allergic contact dermatitis (33%) and endogenous eczema (11%). Women were significantly more likely to have soaps and detergents (P < 0.001) and water/wet work (P < 0.001) as causes of their ICD than men. Men were significantly more likely to have oils and coolants (P < 0.001) and solvent exposures (P < 0.001) as causes of their ICD. Occupational groups with the highest incidence of OSD were the hair and beauty professions (70 per 100 000), followed by machine and plant operators (38 per 100 000) and health-care workers (21 per 100 000). CONCLUSION: We confirm the importance of occupational contact dermatitis as the most common cause of OSD, with ICD being the most common diagnosis. There are differences in the causes of ICD between our group of male and female workers. For the first time in Australia, rates of OSD in certain industries have been calculated.
