In Romania, data on patch testing are lacking and the significance and applicability of the European baseline series (EBS) needs to be evaluated. The aim of the study was to examine the prevalence of contact allergy to the EBS and to determine the most common post-test sensitization occurred in the population of patients with suspected allergic contact dermatitis in Romania. Demographic data were collected from 252 patients with suspected allergic contact dermatitis. Pacients were patch tested with 28-allergen EBS.The positive patch test was observed in 80.16% patients. The most prevalent contact allergens were nickel sulphate (15.08%), fragrance mix I & II (13.10%) and potassium dichromate (9.52%). Differences in sensitization prevalences to some allergens of the EBS compared with other European countries were recognized. The current EBS is a suitable diagnostic tool for contact allergy in Romania.

Background: Contact dermatitis to personal sporting equipment in youth is poorly studied. Objective: To review the results of patch testing 6 youth to their sporting equipment in a dermatology general private practice from 2006 to 2011. Methods: A retrospective analysis of 6 youth aged 11 to 14 who were evaluated for chronic and persistent dermatitis occurring in relation to sports equipment was conducted. All patients were subjected to epicutaneous (patch) testing, which included some or all of the following: North American Contact Dermatitis Group (NACGD) series, textile series, rubber series, corticosteroid series, and raw material from the patients’ own personal equipment. Results: All cases had 1 or more positive patch test reactions to an allergen within the aforementioned series, and 3 subjects tested positive to their personal equipment in raw form. Conclusions: Allergic contact dermatitis, not irritant, was deemed the relevant cause of chronic dermatitis in 4 of the 6 patients due to positive reactions to epicutaneous tests and/or personal equipment. The utility of testing to patients’ own sporting equipment was shown to be of additional value and should be considered when patch testing for contact allergy to sporting equipment.

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.

AbstractTemporary henna tattoos have recently become increasingly popular, especially among teenagers. Combining henna with other colouring agents such as para-phenylenediamine (PPD) may increase its potential for contact sensitization, cross-reaction to related compounds, as well as life-long allergy. Several cases of contact dermatitis from temporary tattoos with black henna have been reported in the literature. We present our experiences with 4 pediatric cases of allergic contact dermatitis induced by henna tattooing and give a brief review of the literature. The agent responsible for contact allergy was proven to be PPD in 3 patients, and in one patch testing revealed positive reactions to PPD and benzocaine, as well as to wool alcohols, nickel sulphate and potassium dichromate, to previously used hair dye—all being of clinical relevance.

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.

Objectives: First, this research was instituted to identify common allergens, and second, to test the association between IL16 gene promoter polymorphism rs4778889 T/C and allergic contact dermatitis (ACD). Methods: A case control study was conducted in dermatology outpatients’ clinic. Study subjects received interview-based semi-structured questionnaire, complete skin examination, IL16 gene promoter was investigated by PCR-RFLP (polymerase chain reaction-restriction fragment length polymorphism) analysis, and IQ Ultra™ patch test units (Chemotechnique Diagnostics AB, Sweden) with 10 substances were used. Results: Most of the prevalent cases had positive patch test (93.3%). The most common clinical presentation of ACD in our patients was itching (96.7%), followed by dryness (86.75%), erythema (76.7%), and fissuring (76.7%). There was higher CC gene distribution among cases, but there was no statistically significant difference. IL16 gene distribution was nearly similar among different clinical presentations. Formaldehyde showed statistically significant higher frequency for CC. The most common allergen found was mercury chloride (76.6%), followed by potassium dichromate (26.6%) and cobalt chloride (20%). Conclusions: The current study found prominent metal sensitization (mercury chloride) over the previously known potassium dichromate. There was no statistically significant IL16 gene distribution among cases compared with control. However, C allele was more frequently encountered in cases. Further studies are required to test the association with IL16 genotype and ACD and highlight the new trends in metal sensitization among cement-exposed workers.

Background: The relationship between atopic dermatitis and allergic contact dermatitis is frequently debated, particularly in children. The impaired skin barrier of atopic subjects can facilitate the penetration of exogenous agents and its mutations in the filaggrin gene might be implicated in an increased risk to develop contact dermatitis. Moreover, atopic children are protractedly exposed to chemical substances contained in skin care products from an early age. Patients And Methods: The aim of this retrospective study is to determine if atopic children are more prone to allergic contact dermatitis and which substances are more frequently related to this disease. From 2014 to 2016, a total of 268 children under 14 years with a history of eczematous dermatitis, of whom 141 (52.6%) were affected, and 127 (47.4%) were not affected by AD, underwent patch testing with the baseline S.I.D.A.P.A standard series. Results: Based on the results of our study, the prevalence of contact allergy in atopic children is comparable to that noted in non-atopic children. The most frequent causes of contact allergy in children are fragrances, and their prevalence is significantly higher in atopic children (19.9%) than in non-atopic ones, (11.8%; p < .05). Conclusion: Our study highlights the importance of patch testing in atopic children for continuously monitoring the trends and changes of contact allergies that are a common disease and is even significantly increasing for some allergens, as fragrances. We may speculate that the protracted use of skincare products, associated with the impaired skin barrier of atopic children, enhances the risk of sensitization to the ingredients of these products.

Background: Patch testing is routinely used in contact dermatitis clinics because it is the gold standard for the evaluation of potential allergic contact dermatitis. Objective: The study was undertaken to evaluate possible differences in reactivity between the Finn Chamber and IQ-Ultra patch-testing methodologies. Methods: Patients were patch-tested simultaneously with the Finn Chamber and IQ-Ultra patch tests. Ten standard allergens set by the North American Contact Dermatitis Group were used for both techniques. Results: Both patch tests had a significant agreement in detecting all of the allergens. An “almost perfect agreement” was noted for ethylenediamine dihydrochloride, quaternium-15, mercapto mix, black rubber mix, balsam of Peru, and nickel sulfate; “substantial agreement” for formaldehyde, bisphenol A epoxy resin, and 4-tert-butylphenol formaldehyde resin; and “moderate agreement” for potassium dichromate. Conclusion: The Finn Chamber and IQ-Ultra patch tests had a good agreement in the detection of the 10 standard allergens that were tested.
