Background: The pattern of contact sensitisation should be monitored in order to detect the changing trend of sensitising allergens. We aim to evaluate contact sensitisation in adults suspected to have allergic contact dermatitis. Methods: This is a five-year retrospective review on contact sensitisation in adults patch-tested with the European Standard and extended series between 2011 and 2015 in the Department of Dermatology, Hospital Kuala Lumpur. Results: There were 689 adults (M:F= 1:2.04; mean age 40.5 years) who were patch-tested. The majority (175, 25.4%) were white collar workers and 118 (17.1%) were healthcare workers. The provisional diagnoses of patients included contact dermatitis (80.8%); endogenous eczema (7.9%); hand eczema (3.2%); hand and foot eczema (3.5%); foot eczema (1.4%) and photodermatitis (1.2%). The allergens selected for testing were based on past and present history of exposure. Almost all (688, 99.8%) were patch-tested with the European standard allergens and 466 (67.6%) were tested with the extended series. About three quarter (528, 76.6%) developed at least one positive reaction. The top five most frequent reactions were to nickel sulphate (35.3%); potassium dichromate (16.5%); methylchloroisothiazolinone (12.9%), fragrance mix I (12.6%), and cobalt chloride (10.2%). The commonest sensitisations identified in the extended series were palladium chloride (23/105, 21.9%), stannous chloride (18/85, 21.2%), miconazole (7/44, 15.9%), gold(I)sodium thiosulfate (16/105, 15.2%) and thimerosal (29/202, 14.4%). Conclusion: Contact sensitisation was detected in 76.6% of adults patch-tested. Nickel sulphate was found to be the most frequently sensitising allergen. The rising prevalence of methylchloroisothiazolinone/methylisothiazolinone sensitization poses significant concern.

There were 52 patients (30 females and 22 males) suffered from allergic dermatitis admitted to at the Department of Allergology and Clinical Immunology in Bach Mai Hospital (1999-2003). The results showed that: Antibiotic use is main cause of alergic dermatitis, in which phenicol class related to most cases. There were 4 main symptoms of allergic dermatitis: itching, erythema, oedema and vesicle. Symptoms always happened lately. Glucocorticoids, antihistamins and vitamin C are main medications to treat patients with allergic dermatitis.

Topical steroid is one of the main armaments for dermatologists, but it can cause many unwanted side effects. Allergic contact dermatitis, even if it is rare, is one of them and would fall the physician in to confusion. So it is important to consider this problem in the case of dermatitis with no or poor response to appropriate topical steroid therapy. We herein report a case of allergic contact dermatitis caused by topical hydrocortisone cream.
