Background: In allergic contact dermatitis (ACD), polysensitization consists of positive patch test reactions to three or more unrelated allergens. Objective: The purpose of this case report is to document a 27-year-old female with recurrent lip dermatitis, polysensitization, and reactions to a number of clinically relevant exposures. Methods: Patch testing results revealed positive reactions to tixocortol-21-pivalate (3+), lanolin (3+), neomycin (3+), nickel (1+), hydroxyethyl methylacrylate (3+), bacitracin (3+), and abitol (3+). Results: The patient had seven positive reactions, meeting the criteria for polysensitization. Of known clinical relevance, the patient had applied lanolin-containing lip balms and hydrocortisone- and bacitracin-containing products to the lips, all of which she was strongly reactive to on patch testing. Conclusion: Polysensitization occurs when three or more unrelated allergens are positive on patch testing. This case highlights the importance of considering polysensitization in ACD as numerous allergens that were positive on patch testing were clinically relevant.

Introduction: Allergic contact dermatitis in Nepal is not an uncommon disorder. Patch testing is a well established method of diagnosing allergic contact dermatitis. Patients with contact dermatitis are well known to have impaired quality of life which often leads to frequent dermatological consultations.Objective: Lack of data from Nepal has prompted us to undertake this study with the aims to know the frequency of allergic contact dermatitis and the commonest contact allergens among the patients with Hand eczema attending the out-patient department of dermatology, B.P. Koirala Institute of Health Sciences and Kathmandu Medical College Teaching Hospital.Material and Methods: A total of 256 patients were included in the study. Out of them 195 with hand eczema agreed to participate and undergo patch testing. The antigens used included the Indian standard series of patch test allergens approved by Contact and Occupational Dermatoses Forum of India.Results: Hundred and ten cases (56.4%) were patch test positive (PTP) at 48 as well as 96 hours to at least one allergen. PTP was seen more commonly in females. The most common allergen in females was nickel sulphate followed by cobalt chloride, gentamicin and mercapto mix while males were positive to potassium dichromate, followed by epoxy resin, fragrance mix and nickel sulphate.Conclusion: Patch testing has proved a useful tool for the detection of allergic contact dermatitis and for identification of contact allergens. When positive reactions correlate with environmental exposure the test usually assists the physician in establishing the cause of dermatitis, hence treating the patients and improving their quality of life.Nepal Journal of Dermatology, Venereology & Leprology, Vol.14(1) 2016, pp.14-17

Objectives: The objective of the study was to identify the allergens showing positive patch test reaction (using Indian standard battery of allergens) in cement workers with clinically diagnosed allergic contact dermatitis (CD) to cement attending a tertiary referral center. Materials and Methods: We included cement workers with clinically diagnosed allergic CD to cement who attended the dermatology outpatient clinic of our tertiary referral center from January 2013 to December 2013. We did patch testing in all the cases ( after subsidence of active dermatitis) with Indian standard battery of patch test allergens and documented the allergens that showed a positive reaction. Results: Forty-seven (94%) of the 50 study participants showed a positive reaction to one or more of the allergens. The most common allergen that showed a positive reaction was potassium dichromate (43/50, 86%). Twenty-five patients (50%) showed positive reactions to more than 1 allergen. Four patients (8%) showed positive reactions only to allergens that were not seen in cement. Limitations: Small sample size and lack of information on clinical response of dermatitis to avoidance of identified allergen were the major limitations. Conclusion: Twenty-five (50%) patients showing positive reactions to more than 1 allergen tested and 4 (8%) showing positive patch test reaction to none of the allergens in cement (but to other allergens) highlight the role of patch testing in identifying the probable allergens in patients with clinically diagnosed allergic CD to cement.

Introduction: Facial contact dermatitis has exponentially increased in the past decade because of the freely available over the counter topical medications and the innumerable cosmetics. Patch testing is still the gold standard for diagnosis. Aims and Objectives: To elicit the patterns and specic allergens causing facial dermatitis on face in Indian patients. 50 patients of predominantly facial dermatitis with Materials and methods: suspected contact dermatitis (CD) were taken up for patch testing. The patients were tested with the Indian standard series (ISS) and Indian cosmetic series and the results were read at 48 and 96 hours. Repeated open application test (ROAT) was performed with the suspected allergens in 33 patients, and the results were read on Days 2, 4, and 7 using the Johansen's Modied scale. Results: The mean age of the patients was 48.3 years with M: F ratio of 3:7. The mean duration of the complaints was 20 months, while the mean duration of exposure to the implicated allergen was 10.6 years. Patch test with ISS and cosmetic series were positive in 34% of people with 4-Phenylenediamine base PPD (1%) being the most common allergen in 14 patients. ROAT was positive in 18 patients, out of which 78% were patch test negative. Patch test has stood the test of Discussion: time as an invaluable diagnostic aid in patients with dermatitis. Sindoor dermatitis is a commonly encountered ACD in our clinics but the implicated allergens are not a part of ISS or cosmetic series. In our study, ROAT was positive in 8 patients of sindoor dermatitis who were patch test negative. Thus, ROAT should also be ideally be performed in these patients.

AbstractA deterioration in chronic inflammatory ear disease despite topical medication, or failure of the condition to improve with such treatment, should raise the possibility of allergic contact dermatitis. Allergen testing (patch testing) is the ‘gold standard’ method of identifying an agent causing allergic contact dermatitis.We describe an ENT patch test series applied by our department as a screening device for this condition.

Background: The reliability of patch testing with expired Indian standard patch test kits has been not evaluated before. Methods: Thirty adults (men:women 25:5) with allergic contact dermatitis were divided into three groups of ten patients each for patch testing by Finn chamber® method using Indian standard patch test kits having expiry in 2016, 2015 and 2014. The results were compared with those from a new kit with 2018 expiry. Results: Ten patients in group-1, eight patients in group-2 and seven patients in group-3 developed positive reactions of identical intensities and mostly from identical allergens from all four kits. The major contact allergens eliciting positive reactions of identical intensities were parthenium in nine, five and three patients, colophony in four, one and zero patients, fragrance mix in three, three and one patients, thiuram mix in three, one and one patients, and paraphenylene diamine in two, one and three patients from group-1,-2, and -3, respectively. Limitations: Small number of patients in each group remains the major limitation of the study. Whether or not these results can be extrapolated with patch test results from other similar patch test kits available across countries also needs confirmation. Conclusion: The patch test allergens can be used beyond labeled expiry dates but needs confirmation by a few large studies and using other available patch test kits. This is important as the relevance of patch test results for individual allergen in this scenario may remain debatable requiring careful interpretation.

Allergic contact dermatitis (ACD) is one of the most common diseases presenting to the Dermatology department. The one and only method of preventing as well as treating this disease is avoidance of the allergen causing it. The identification of the allergen causing the ACD is possible by performing patch testing. The purpose of this study was to identify common allergens among patients with ACD using Indian standard series (ISS) of patch test. Clinically suspected cases of ACD were included in the hospital based cross-sectional study from January to December 2017. These cases underwent patch testing with the ISS. The study assessed the following variables: sex, age, occupation, site and positive patch test results. There were a total of 58 patients among which, 36.2% were males and 63.8% were females with a mean age of 32.36±12.51 years. Positive patch test reactions were seen in 63.0% of patients. The most common allergens were nickel sulphate (51.4%), fragrance mix (37.8%), potassium dichromate (8.1%), colophony (8.1%) and black rubber mix (8.1%). Among male, most common allergens were fragrance mix (57.1%), nickel sulphate (28.6%) and potassium dichromate (21.4%) while in female, most common allergens were nickel sulphate (65.2%) and fragrance mix (26.1%). In our study, majority of the allergens were positive. Hence, the ISS used in the study might be suitable in the context of Nepalese population. However, further similar studies on large number of patients with multiple allergens are required to determine the exact number of contact allergens prevalent in our population.
