Interventions for preventing occupational irritant hand dermatitis
Background: Occupational irritant hand dermatitis (OIHD) causes significant functional impairment, disruption of work, and discomfort in the working population. Different preventive measures such as protective gloves, barrier creams and moisturisers can be used, but it is not clear how effective these are. This is an update of a Cochrane review which was previously published in 2010. Objectives: To assess the effects of primary preventive interventions and strategies (physical and behavioural) for preventing OIHD in healthy people (who have no hand dermatitis) who work in occupations where the...
Dermatite de contact aux protéines
La dermatite de contact aux protéines est une dermatose professionnelle sous-estimée. Les principales professions concernées sont les métiers de la restauration et de l'alimentation et les métiers en contact avec les animaux. Les sources de protéines sensibilisantes sont les aliments d'origine végétale (fruits, légumes, farines, épices) et animale (viandes, oeufs, produits laitiers, poissons et crustacés), les champignons et enzymes, les végétaux non comestibles et les animaux. Cliniquement, c'est...
Elevation of Circulating Th17/Th22 Cells Exposed to Low-Level Formaldehyde and Its Relevance to Formaldehyde-Induced Occupational Allergic Contact Dermatitis
Objectives: The aim of this study was to investigate the effects of formaldehyde exposure on Th17 and Th22 cells and its relevance to human occupational allergic contact dermatitis (OACD). Methods: Circulating IL17-/IL22-secreting cells and serum IL17/IL22 levels in formaldehyde-exposed workers at Occupational Exposure Limit and nonexposed controls were assessed. Results: The IL17+ and IL22+ cell population were detected in both CD3+CD8- and CD3+CD8+ cells. The percentages of circulating IL17+ and IL22+ T cells in the workers with and without ACD history were all elevated, which were more remarkable...

Genetic Basis of Irritant Susceptibility in Health Care Workers
Objective: The aim of this study was to investigate the association of single nucleotide polymorphisms (SNPs) within genes involved in inflammation, skin barrier integrity, signaling/pattern recognition, and antioxidant defense with irritant susceptibility in a group of health care workers. Methods: The 536 volunteer subjects were genotyped for selected SNPs and patch tested with three model irritants: sodium lauryl sulfate (SLS), sodium hydroxide (NaOH), and benzalkonium chloride (BKC). Genotyping was performed on genomic DNA using Illumina Goldengate custom panels. Results: The ACACB (rs2268387...
Dermatites de contact professionnelles chez les vétérinaires et les personnels de soins aux animaux
Les dermatites de contact professionnelles observées chez les vétérinaires, le personnel des zoos (dont les soigneurs) et des animaleries de compagnie (vendeurs-conseil, personnels de nettoyage) sont des dermatites de contact d'irritation et/ou allergiques, des urticaires de contact et des dermatites de contact aux protéines. Les principaux irritants sont les désinfectants et détergents, le travail en milieu humide. Les principaux allergènes sont les protéines d'origine animale, les médicaments, les biocides (notamment dans...
Irritant Contact Dermatitis
A Survey of Healthcare Worker Knowledge, Perceptions and Actions Health Care Workers (HCWs) often cite irritant contact dermatitis (ICD) as a barrier to Hand Hygiene (HH) compliance. Literature supports the cause of ICD on hands, but little data exists on steps HCWs follow to address ICD. The objective of this survey was to quantify knowledge, perception and actions of HCWs to ICD. Source: McGuckin, Maryanne, & Govednik, John. (2016).

Dermatites de contact professionnelles dans le secteur de l'imprimerie
Les dermatites de contact professionnelles sont fréquentes dans le secteur de l'imprimerie. Il s'agit essentiellement de dermatites de contact d'irritation et/ou allergiques et plus rarement d'urticaires de contact. Les principaux irritants sont les solvants des produits de nettoyage, les acides, les produits alcalins de décapage et de dégravage, ainsi que les constituants des encres. Les principaux allergènes sont les constituants des résines et des vernis (surtout les acrylates) et les biocides. Le diagnostic étiologique nécessite...
Occupational irritant contact dermatitis diagnosed by analysis of contact irritants and allergens in the work environment
BACKGROUND: Irritant contact dermatitis (ICD) is a common diagnosis in patients with occupational contact dermatitis (OCD). Studies are lacking on the usefulness of material safety data sheets (MSDSs) in making the diagnosis of ICD. OBJECTIVE: To characterize irritant exposures leading to the diagnosis of occupational ICD (OICD), and to evaluate the occurrence of concomitant exposures to contact allergens. METHODS: We included 316 patients with suspected occupational hand dermatitis, referred to the Department of Dermato-Allergology, Copenhagen University Hospital Gentofte, Denmark during January...
A survey of exposure to enzymes in cleaning solutions used to clean endoscopes - RR972
Proteolytic enzymes are a recognised risk for respiratory and dermal allergy. Cases of asthma have been identified in health care workers using cleaning solutions containing these enzymes to decontaminate endoscopes and surgical equipment. An assessment was made of three hospitals using enzyme products to clean endoscopes. Air samples showed that approximately a third of the personal and a half of the static air samples contained protease activity at levels that may pose risk for allergic sensitisation. Wipe samples demonstrated protease on surfaces where manual pre-cleaning of endoscopes was undertaken...
Investigation of respiratory and dermal symptoms associated with metal working fluids at an aircraft engine manufacturing facility
Background Each year, 1.2 million metalworkers are exposed to metalworking fluids (MWFs), which can cause dermal and respiratory disease. The National Institute for Occupational Safety and Health (NIOSH) conducted a health hazard evaluation of MWF exposures at an aircraft engine manufacturing facility. The objectives were to determine employee exposures to endotoxin and MWFs in the air, characterize symptoms experienced by employees working with MWFs, compare them to symptoms of employees unexposed to MWFs, and make recommendations for reducing exposures based on results. Methods Four hundred seven...
Evaluation of Systemic Health Effects Following Dermal Exposure to Chemicals - TR 119
Risk assessment of chemicals, including the REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) legislation, also cover assessments of dermal risk arising from exposure to chemicals. The European Centre for Ecotoxicology and Toxicology of Chemicals (ECETOC) has produced this guidance consisting of a tiered approach for the risk assessment of dermal exposure to a chemical. The process developed by the Task Force consists of three linked decision trees, i.e.: Derivation of a health-based reference value; Initial risk characterisation; Refined risk characterisation. It is...

Effects of Skin Contact with Chemicals: Guidance for Occupational Health Professionals and Employers
Chemical exposure in the workplace is a significant problem in the United States. More than 13 million workers in the United States are potentially exposed to chemicals via the skin. Skin disorders are among the most frequently reported occupational illnesses, resulting in an estimated annual cost in the United States of over $1 billion. While the rates of most other occupational diseases are decreasing, skin disease rates are actually increasing. Source : http://www.cdc.gov/niosh/docs/2011-200/pdfs/2011-200.pdf
Skin...Exposed!
Take a postage stamp. Stick it to your arm. You've just covered 16 million cells, 55 hairs, 8 meters of nerves, 17,000 nerve endings, 5 meters of blood vessels, 500 sweat glands, and 83 oil glands. You've also just wasted 44 cents. Your skin is marvelously complex. It is your largest organ, accounting for 10% of your body's mass. It is also the site of 15 to 20 percent of all reported work-related illnesses according to the US Bureau of Labor Statistics. Skin can suffer direct, sensitizing, or systemic effects when exposed to hazardous chemicals. Direct exposure can corrode, irritate...
