BackgroundIrritable Bowel Syndrome (IBS) is a functional gastrointestinal (GI) disorder of unknown etiology.ObjectiveWe sought to investigate whether specific type 4 food allergens identified by skin patch testing, when eliminated from the diet, alleviate symptoms of IBS.MethodsIn this case series, skin patch testing was performed on 60 IBS patients using an extensive panel of type 4 food allergens after which food avoidance diets directed by the patch test results were implemented. Questionnaires assessing abdominal pain/discomfort and global improvement in IBS symptoms were used to assess one month and three or more month outcomes. ResultsThere were statistically significant improvements in abdominal pain/discomfort and in global IBS symptoms after one month and again at an average of 7.6 months of patch test-guided food avoidance.ConclusionsSustained improvement with avoidance of type 4 food allergens identified by skin patch testing suggests a role for delayed-type food hypersensitivities in the pathogenesis of some cases of IBS. A subset of patients whose IBS symptoms resolve completely may be better characterized as having a newly proposed disease, allergic contact enteritis (ACE).

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.

Background Red scrotum syndrome (RSS) is not infrequent but is often misdiagnosed or underdiagnosed, and seldom reported. The exact etiopathogeneis is still unknown but it almost always follows the prolonged application of topical corticosteroids and is characterised by persistent erythema of the scrotum, associated with severe itching, hyperalgesia and a burning sensation. Objective: To evaluate the clinicoepidemiological profile and assess the efficacy of various treatment modalities in addition to corticosteroid abstinence in the treatment of RSS. Methods: Twelve patients with RSS, who presented to us during 2010 and 2011, were identified, and various aspects of their illness and treatment were studied. Patch testing was performed in all patients. A skin biopsy was done in seven patients. Results: The average age of the patients was 45.83 years (26–62 years). The average duration of illness or the duration of topical steroid use was 27.41 months (6–56 months). Psychiatric comorbidities were seen in 9 (75%) out of 12 patients. Histopathology revealed features resembling erythematotelengiectatic rosacea in four of the biopsied patients. Patch test results were negative. All patients reported improvement of their symptoms within 4 weeks of starting doxycycline with amitriptyline or pregabalin; the treatment had to be continued for 3–4 months. Conclusions: RSS appears to be a manifestation of corticosteroid misuse rather than a primary disease. We suggest that RSS is a rosacea-like dermatosis or steroid-induced rebound vasodilation based on clinical and histopathological features. Our patients responded to cessation of steroids and doxycycline in combination with amitryptaline or pregabalin.

AbstractBackgroundDermatological services in Laos, South East Asia are limited to the capital and patch testing is currently not available, so no data exists regarding the common cutaneous allergens in this population.ObjectivesThe aim of this study was to document common allergens in medical students in Laos. Patients/Materials/MethodsOne hundred and fifty medical students were patch tested using TRUE Test® panels 1 to 3 (35 allergens). Readings were taken at Days 2 and 4.ResultsThirty-eight students (25.3%) had a positive reaction to at least one allergen, accounting for 52 reactions in total. The proportion of the students with positive patch test reading was significantly higher in the female [33/96 (34%)] than in the male [5/54 (9%)], p<0.001. The most common allergens were: nickel (10%), gold (6.6%), thiomersal (6.6%), cobalt dichloride (2%) and p-tert-Butylphenol formaldehyde resin (2%). Balsam of Peru (0.66%), black rubber mix (0.66%), Cl+Me-Isothiazolinone (0.66%), fragrance mix 1 (0.66%), quinolone mix (0.66%), methyldibromo glutaronitrile (0.66%), mercapto mix (0.66%), epoxy resin (0.66%), paraben mix (0.66%), thiuram (0.66%) and wool alcohols (0.66%) accounted for all of the other positive reactions.ConclusionThis study represents the first documented patch test results in Lao medical students and in the adult Lao population. The results of this study will inform any future research into contact allergy in Laos and give an insight into the background level of contact sensitivity in this population.

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.

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: 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
