Abstract
INTRODUCTION: Airborne contact dermatitis is a morphological diagnosis involving exposed parts of the body caused by substances which settle on the skin when released into air. Contact dermatitis is one of the most common skin disorders all over the world which accounts for 4-7% of all dermatological consultations. Prevalence of ABCD is difficult to estimate, as it is cumbersome to prove and less often mentioned in literature. Epidemiologically ABCD is classified as occupational and non-occupational ABCD. The gold standard method for identifying the causative allergen of ACD is patch testing. Patch testing can be done to find out the specific allergen in ABCD. AIM OF THE STUDY: To study the epidemiological pattern, various clinical presentations, influence of risk factors and various allergens causing airborne contact dermatitis. METHODOLOGY: The study population comprised of 50 patients with signs and symptoms of airborne contact dermatitis attending the Department of Dermatology, Madras Medical College, Chennai between January 2018 to December 2018. Detailed history taking, risk factor assessment, clinical examination and patch test with Indian standard battery series was done and results were noted. RESULTS: Prevalence of the disease was more common in males (86%), 38% being farmers and 22% cement workers. Most common age group affected was 60-69 years. About 94% cases showed positivity to one or more allergens namely parthenium 38%, potassium bichromate 12%, paraphenylenediamine 8%, nickel, cobalt and black rubber mix each 6%, colophony 4% and formaldehyde 2%. Polysensitivity was noted in 12% cases frequently among female atopic cases. Airborne allergic contact dermatitis was observed as the most common presentation of ABCD in our study. CONCLUSION: Identification and avoidance of the specific allergen in a particular group of people or certain occupation helps the patient by improving their clinical condition, emotional status, quality of life and render them free of the disease. Pre-organisation of the working conditions, deweeding and implementation of necessary protective measures for the employees reduce the incidence and prevalence of the disease. This study emphasizes the need for the addition of other plant allergens and other allergic constituents of various substances in the routinely used patch test kits to improve the outcome.
