Methylisothiazolinone and benzisothiazolinone are widely used in paint: a multicentre study of paints from five European countries

In view of the current epidemic of contact allergy to methylisothiazolinone (MI), it is important to clarify the extent of use of MI and related isothiazolinones in paints currently available for the consumer and worker in Europe.

One thousand cases of severe occupational contact dermatitis

Background.

Occupations at risk of developing contact allergy to isothiazolinones in Danish contact dermatitis patients: results from a Danish multicentre study (2009–2012)

In recent years, the prevalence of contact allergy to isothiazolinones has reached epidemic levels. Few studies have presented data on occupations at risk of developing contact allergy to isothiazolinones.

Failures in risk assessment and risk management for cosmetic preservatives in Europe and the impact on public health

In view of the current and unprecedented increase in contact allergy to methylisothiazolinone (MI), we characterized and evaluated two recent epidemics of contact allergy to preservatives used in cosmetic products to address failures in risk assessment and risk management.

Occupational contact dermatitis in hairdressers: an analysis of patch test data from the Danish Contact Dermatitis Group, 2002 - 2011

Occupational contact dermatitis among hairdressers is frequent, owing to daily exposure to irritants and allergens.

Occupational contact dermatitis in blue-collar workers: results from a multicentre study from the Danish Contact Dermatitis Group (2003–2012)

Blue‐collar workers have a high risk of occupational contact dermatitis, but epidemiological studies are scarce.

Occupational contact dermatitis in hairdressers

Occupational contact dermatitis among hairdressers is frequent, owing to daily exposure to irritants and allergens.

The epidemic of methylisothiazolinone : A European prospective study

The use of methylisothiazolinone (MI) in cosmetic products has caused an unprecedented epidemic of MI contact allergy. Current data concerning exposures at a European level are required.

Occupational irritant contact dermatitis diagnosed by analysis of contact irritants and allergens in the work environment

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.

Contact Allergy in Danish Healthcare Workers: A Retrospective Matched Case-control Study

Contact dermatitis in healthcare workers is a world wide problem. We conducted a retrospective observational study of the patch-test results of 1402 healthcare workers and 1402 matched controls with contact dermatitis who were treated at 3 hospitals departments in Denmark between 2007 and 2014. The primary objective was to determine whether healthcare work was associated with contact allergy to thiuram mix. Unadjusted univariate analyses revealed that healthcare work was significantly associated with occupational contact dermatitis and hand dermatitis. Contact allergy to thiuram mix was more common in healthcare workers was significantly associated with having occupational contact dermatitis, hand dermatitis and older age. In conclusion, we report here a potential problem of contact allergy to thiurams in healthcare workers with contact dermatitis. Legislative authorities may in the future focus on the use of rubber accelerators in, for example, protective gloves, which are widely used by healthcare professionals.
