to study the contact sensitivity pattern in patients of hand eczema
Introduction: The word eczema refers to a broad range of conditions that begin as spongiotic dermatitis and may progress to a lichenified stage. Hand eczema (HE) implies that the eczema is largely confined to hands. Aims and objectives: To study the pattern of contact sensitization in hand eczema by the use of patch test. Materials and methods: All new consecutive patients of hand eczema, regardless of age and sex were included. Each hand was divided into five areas (finger tips, fingers, palms, back of hands and wrist) and the intensity of the six following clinical signs: erythema, induration/papulation, vesicles, fissuring, scaling and edema were graded. The patients were then underwent patch testing (Indian Standard Battery). Results: A total of 40 patients of hand eczema were included in the study. Hyperkeratotic eczema (36.3%) was the most common type of hand eczema followed by housewife eczema (26.3%).27 patients showed positivity to various allergens. Potassium dichromate was the most common allergen with 10 (47.6%) patients sensitive to it followed by Nickel sulphate 7 (38.1%), Fragrance mix 3 (11.9%), PPD 2 (9.5%), Wool alcohol 2 (9.5%),Balsum of Peru, Cobalt Chloride and Parthenium allergy was detected in 1 (4.8%) each. Conclusion: HE is a common multifactorial dermatosis. Patch testing is the common investigation done to find out contact sensitivity in cases of HE. Identification of contact sensitizer helps in the management of patients by adopting appropriate preventive and therapeutic measures. Limitations: The limitation of our study was small sample size.
