- Background: Insulin pumps and glucose monitoring devices improve diabetes mellitus control and enhance patients' quality of life. However, a growing number of adverse cutaneous reactions related to the use of these devices have been reported. Objective: To investigate the culprits of localized contact dermatitis in paediatric patients with diabetes caused by insulin pumps and glucose monitoring devices. Methods: Retrospective analysis of 15 paediatric patients patch tested as part of a clinical investigation for skin reactions associated with insulin pumps and glucose monitoring devices. Results: Seven patients had positive patch test reactions to isobornyl acrylate (IBOA) and five had positive reactions to benzoyl peroxide (BP). Positive patch test reactions to materials from the glucose sensor and/or insulin pump were seen in 10 of the 15 patients. Three had positive reactions to adhesive remover wipe from Smith and Nephew Remove and four had reactions to EMLA plaster. Conclusion: A high share of patients showed positive reactions to IBOA and/or their medical devices (insulin pumps or glucose devices). A third of patients showed positive reactions to BP. The presence of additional unidentified allergens cannot be excluded, highlighting the importance of access to a full description of the chemical composition of the devices.

4,4′-Thiobis(2-tert-butyl-5-methylphenol), an antioxidant in medical devices that may cause allergic contact dermatitis
- 2023

- Background: Antioxidants in medical devices, added to protect polymers or adhesives, may also cause contact dermatitis in some individuals. Objectives: To present data on sensitization to 4,4′-thiobis(2-tert-butyl-5-methylphenol), an antioxidant detected in some types of medical devices, for six patients that experienced eczematous reactions to different medical devices. Methods: Patch testing with 4,4′-thiobis(2-tert-butyl-5-methylphenol), 1% pet was performed. Gas chromatography-mass spectrometry (GC-MS) was used for identification of 4,4′-thiobis(2-tert-butyl-5-methylphenol) in different medical device products. Results: Six patients with contact allergy to 4,4′-thiobis(2-tert-butyl-5-methylphenol) also had relevant contact allergic reactions to medical devices containing the antioxidant. The presence of the antioxidant in products was detected using GC-MS analysis. Conclusions: The antioxidant 4,4′-thiobis(2-tert-butyl-5-methylphenol) may cause allergic contact dermatitis after exposure to different medical devices.

Contact allergy to oxidised geraniol may be over-represented in individuals with photocontact allergy to ketoprofen
- 2024

Tidskriftsartikel (refereegranskat)abstract
- Background: Simultaneous overrepresentations of contact allergies and photocontact allergies are common in individuals with photocontact allergy to ketoprofen. Aims: To investigate whether contact allergy to oxidised (ox.) geraniol, geraniol, geranial, neral and citral is overrepresented in individuals with photocontact allergy to ketoprofen. Methods: The contact allergy rates to ox. geraniol, geraniol, geranial, neral and citral in routinely patch tested dermatitis patients were compared with the corresponding rates in individuals with photocontact allergy to ketoprofen. Results: Allergic patch test reactions were noted to ox. geraniol 11% (n = 39, 5.8%), ox. geraniol 6% (n = 12, 1.8%), geraniol 6% (n = 2, 0.3%), geranial (n = 18, 2.7%), neral (n = 7, 1.0%) and citral (n = 15, 2.2%). In those four patients who were diagnosed with photocontact allergy to ketoprofen during the test period, a significant overrepresentation (p = 0.020) of simultaneous contact allergy to ox. geraniol 11% was demonstrated. Overrepresentation of simultaneous contact allergy to various combinations of ox. geraniol, ox. limonene and ox. linalool was also noted in ketoprofen-photoallergic patients. Conclusions: Contact allergy to ox. geraniol, geranial and citral is common in routinely tested dermatitis patients. There is an overrepresentation of simultaneous contact allergy to ox. geraniol, ox. limonene and ox. linalool in patients with photocontact allergy to ketoprofen.

The significance of batch and patch test method in establishing contact allergy to fragrance mix I—EDEN Fragrance Study Group
- 2019

Tidskriftsartikel (refereegranskat)abstract
- Background: A fragrance mix consisting of eight separate fragrance ingredients (fragrance mix I [FM I]) is present in most baseline patch test series. Patch testing with the TRUE Test technique is considered to detect less contact allergy to FM I than testing with the Finn Chamber technique. Objective: To investigate the possible significance of batch and patch test method in establishing contact allergy to FM I. Methods: Three thousand one hundred and nineteen individuals representing a sample of the general population were patch tested with two batches of FM I with two patch test techniques at six dermatology clinics in five European countries. The TRUE Test technique and the Finn Chamber technique with pet. preparations were used. McNemar's test was used for statistical calculations. Results: The contact allergy prevalences varied between 0.7% and 2.6%. The patch tests with the mixes containing Evernia prunastri (oak moss) with a high content of chloratranol/atranol resulted in substantially more positive reactions than the corresponding tests with the mixes containing oak moss with a low content of chloratranol/atranol. The Finn Chamber technique detected significantly more contact allergic reactions than the TRUE Test technique (P < 0.001). Conclusion: The Finn Chamber technique detects more contact allergy to FM I than the TRUE Test technique.

Chemical burns caused by trifluoroacetic acid.
- 2013
-
Ingår i: Contact Dermatitis. - : Wiley. - 0105-1873. ; 69:3, s. 176-180

Tidskriftsartikel (refereegranskat)abstract
- Trifluoroacetic acid is a very strong carboxylic acid. The acid has been suspected to have similar toxic effects as hydrofluoric acid on skin contact. Hydrofluoric acid is highly toxic, owing to skin penetration by fluoride ions. A spill of hydrofluoric acid on the skin may be fatal. As trifluoroacetic acid contains fluorine, patients with chemical burns caused by trifluoroacetic acid have been given particular attention when treated in the hospital.
