Objectives: To investigate the prevalence and the severity of fragrance-related symptoms among hairdressers in Denmark compared with the Danish general population. Further, to characterize former hairdressers who are severely chemically intolerant to fragranced products in relation to sex, age and health- and work-related reasons for leaving the hairdressing profession.
Methods: The study population consisted of all hairdressers who graduated from the public vocational schools in Denmark during 1985 and 2007 (n = 7840) and a random sample of individuals from the Danish general population (n = 6000).
Objectives: To evaluate a Danish translation of the Quick Environmental Exposure and Sensitivity Inventory (QEESI).
Methods: The study included two groups: one comprised a random sample of 2000 individuals drawn from the Danish Civil Registration System; the other comprised 315 patients with chemical intolerance.
Results: The evaluation suggested good reliability for the four QEESI scales in terms of internal consistency and coefficients between test and retest scores.
Article Synopsis
- The study explores the link between filaggrin (FLG) deficiency, tobacco smoking, and asthma development.
- It found that individuals with FLG null mutations had a higher prevalence of asthma and reduced lung function, and these effects were exacerbated by smoking.
- The results suggest a significant interaction between FLG mutations and smoking, particularly in nonatopic individuals, potentially informing future risk assessments for asthma in the population.
Multiple chemical sensitivity (MCS) is characterised by adverse effects due to exposure to low levels of chemical substances. The aetiology is unknown, but chemical related respiratory symptoms have been found associated with positive patch test. The purpose of this study was to investigate the relationship between cutaneous reactions from patch testing and self-reported severity of chemical sensitivity to common airborne chemicals.

Various genes, especially genes of importance to the metabolism of xenobiotic compounds, have been associated with MCS, but findings are inconsistent. The purpose of this study was to investigate genetic susceptibility factors for MCS and self-reported chemical sensitivity in a population sample.

Objective: To characterise the chemical exposures and symptoms affecting individuals with subsequent adjustments of social life or occupational conditions, and further characterise these severely affected individuals.
Methods: All individuals (n = 1,134) who reported symptoms from airborne chemical exposures in a population-based questionnaire study of 6,000 individuals were included and dichotomised according to severity. Logistic regression models were used to characterise the group of severely affected individuals.
Objective: To estimate the prevalence and consequences of self-reported symptoms related to inhalation of airborne chemicals in a Danish general population.
Methods: A random sample of 18-69-year-old individuals (n = 6,000) was drawn from the Danish Civil Registration System. A questionnaire on self-reported symptoms related to inhalation of 11 categories of airborne chemicals was mailed to the population.
