Fragrance allergy: assessing the safety of washed fabrics
Background: Previously, a quantitative risk assessment suggested there was no risk of induction of fragrance allergy from minor residues of fragrance chemicals on washed fabrics.
Objective: To investigate whether there was any risk of the elicitation of contact allergy from fragrance chemical residues on fabric in individuals who were already sensitized.
Methods: Thirty-six subjects with a positive patch test to isoeugenol (n = 19) or hydroxyisohexyl 3-cyclohexene carboxaldehyde (n = 17) were recruited. Dose-response and fabric patch tests were performed, respectively, with filter paper and a cotton sample loaded with fragrance in ethanol-diethylphthalate (DEP) and applied in a Finn Chamber (R) or a Hill Top Chamber (R). Results: Only two subjects reacted to an isoeugenol patch test
concentration of 0.01% (>20x the estimated likely skin exposure level), none reacted to lower concentrations. Of 36 subjects, 18 reacted to the fabric patch treated with ethanol-DEP vehicle alone and 20 to the fragrance-chemical-treated fabric patch. These were only minor non-specific skin reactions. They were also quite evenly distributed between the two fragrance chemical allergic groups. Conclusions: On the basis of the examples studied, fragrance chemical residues present on fabric do not appear to present a risk of the elicitation of immediate or delayed allergic skin reactions on individuals already sensitized
Kawasaki disease in adults: observations in France and literature review Short title: Kawasaki disease in adults in France
International audienceObjective Kawasaki disease (KD) is a vasculitis that mostly occurs in young children and rarely in adults. We analyzed the characteristics of adult-onset KD (AKD) in France. Methods We collected retrospective and prospective data for patients with a diagnosis of KD occurring after the age of 18 years. Cases were obtained via various French medical networks and identified from the international literature. Results We included 43 patients of AKD at 26 institution from 1992 to 2015, with mean (SD) age 30 (11) years (range 18â68) and sex ratio (M/F) 1.2; 34 patients met the American Heart Association criteria and 9 were incomplete AKD. The median time to diagnosis was 13 days (interquartile range 8â21). The main symptoms were fever (100%), exanthema (98%), changes in the extremities (91%), conjunctivitis (77%), oral cavity changes (89%), cervical adenitis (55%) and cardiac abnormalities (45%). Overall, 35% of patients showed large-vessel vasculitis: coronary vasculitis (26%) and coronary aneurysm (19%). Treatment was mostly intravenous immunoglobulins (79%) and aspirin (81%). Four patients showed myocardial infarction due to coronary vasculitis, but none were treated with IVIg because of late diagnosis. After a median follow-up of 5 months (range 1â117), persistent aneurysm was noted in 9% of cases. Damage was significantly lower with early treatment than late or no treatment (p = 0.01). Conclusion Given the high frequency of cardiac involvement and complications in this series of AKD, diagnosis and treatment should not be delayed, and early IVIg treatment seems to improve the outcom
