Allergic Contact Dermatitis from Rubber and Plastic Gloves
Published in Robert N. Phalen, Howard I. Maibach, Protective Gloves for Occupational Use, 2023
The glove usage should be started at the same time as the handling of hazardous materials, but gloves made of polymeric materials should not be used needlessly, e.g., during cleaning jobs in which no liquids are handled. The gloves should be for personal use, and the condition of the gloves should be the user's responsibility. Workers with long-lasting dermatitis should be referred to a dermatological examination including appropriate skin testings.1,104
Health and Safety in the Construction Industry
Published in Malcolm Thorpe, Brickwork Level 1, 2021
The health of the site operatives can be divided into the following areas of the human body: Skin – one of the most common problems with the skin is dermatitis. This is caused by contact between the skin and the many cements and plasters on site. To reduce the problem barrier creams could be used or appropriate gloves worn. Most construction sites now provide numerous types of gloves for every situation.Eyes – protection of the eyes has been mentioned previously, but as they are the only ones you have it is important to take extra care and use the appropriate glasses or goggles for the job.Ears – again, most sites provide a selection of ear protectors or plugs to be used when working with or close to noise.Lungs – many construction operations involve dust. It is therefore very important to protect yourself against inhaling any harmful dust. Protective breathing apparatus or simple disposable masks should be available.

The effect of the elimination of allergens on hand dermatitis is extremely variable and unpredictable. When the dermatitis has developed as a result of a significant exposure to a relevant allergen, elimination will cure the dermatitis. Absence of improvement in spite of the elimination of contact allergens is very common and may be due to several causes: The proven contact allergy is not relevant for the current hand dermatitis.Elimination of a relevant allergen is incomplete.The hand dermatitis is caused mainly by endogenous factors and the contact sensitivity is only a minor contributory factor.

Additionally, workers in the MDF furniture factory may be exposed to formaldehyde and urea-formaldehyde resin, either by skin contact or because of the dust generally dispersed around the workplace. MDF dust generally contains 8%–18% formaldehyde and resins.4 This study found that workers in the exposed group, who performed daily tasks of cutting, polishing, drilling, and composing wood, developed symptoms of allergic contact dermatitis, which agrees with studies conducted by Priha et al.21 and Heikkilä et al.,22 who found that workers who performed these tasks in an MDF furniture factory had risks of exposure to wood dust during the process of sawing and sanding, or from the machines. Also, formaldehyde causes sensitization that may result in allergic contact dermatitis, as cited in the University of Pittsburgh Safety Manual.16 Another finding of this study was that the workers who spent more than 2 hour a day using chemicals at home, such as cooking, cloth washing by hand, gardening, dish washing, cleaning, and using chemicals suspected of causing contact dermatitis more than 2 h per day, and those who used bleach one to three times a month during housework, developed symptoms of contact dermatitis, as toilet cleaning liquids and bleach are skin irritants. Subsequently, this can contribute to symptoms of itching, rash, and skin swelling and an increased risk of allergic contact dermatitis.23–26

As one of the most common skin diseases, atopic dermatitis (AD) is a common and chronic inflammatory disorder of the epithelial barrier combined with lesions and intense irritation.[1] Many researchers focused on this filed, and convinced there are many factors could influence the procession of the atopic dermatitis, such as the environmental factors, the wet environment is more likely to induce the atopic dermatitis.[2] The psychological factors are also important for this disease. However, up to now, the clear mechanism about the atopic dermatitis is still controversial, which limit the developing of new drugs against atopic dermatitis.[3] The interleukin usually plays a central role in the pathogenesis of psoriasis of dermatitis. During dermatitis, the immune cells in the body are usually activated and lead to the release of large numbers of inflammatory factors.[4] IL-18, IL-33, TNF-α and total IgE are generally known as the indicators of dermatitis. During dermatitis there will be a significant elevation of these inflammatory medium.[5]

The repeated application of BAC to skin might produce dermatitis (Osol 1980). Concentrated aqueous solutions (≤10%) are known to be primary skin irritants capable of inducing deep necrosis and scarring; a concentration as low as 0.1% is often irritating to conjunctivae and mucous membranes (AMA 1991; Gosselin, Smith, and Hodge 1984). Amin and Belsito (2006) conducted a retrospective analysis of 1215 patch-tested patients over 10 years to identify allergens responsible for allergic eyelid dermatitis. Several allergens, including fragrances, metals, neomycin, oleamidopropyl dimethylamine, tosylamide/formaldehyde resins, and BAC, were attributed as common causes of different types of dermatitis. Lee et al. (2012) investigated the prevalence of allergies to preservatives in 584 patients with suspected cosmetic contact dermatitis in South Korea. The overall frequency of sensitization to preservatives in patch tests was 41% (240/587 patients). BAC produced a positive reaction in 12% patients (71/587), with a low reaction index (0.4). In another irritancy patch test, 30 healthy volunteers were applied 0.1% BAC to the upper arm; of these, a positive irritant response on the fourth day was detected in seven subjects.
