Abstract

In this study, males were commonly affected than females with a ratio of 2.1:1. Patients in the age group 30 – 40 years were commonly affected. Most of the patients were exposed occupationally Farmers predominated the occupational group and housewives predominated the non occupational group. Among the males, occupational exposure was common but in females non occupational exposure was common. The duration of occupational exposure ranged from 6 months to 50 years. The duration of complaints ranged from less than a month to 10 years. There was no correlation between duration of occupational exposure and onset of disease. About 16% of the patients had atopy. 31% of the patients gave a history of photosensitivity. Airborne contact dermatitis was the most common pattern observed. Parthenium was the most common allergen. CONCLUSION: 1. In this study among patients with phytodermatitis, males outnumbered females with a ratio of 2.1:1. 2. Most cases of allergic contact dermatitis to plants belonged to the age group 30 – 40 years. 3. Occupational exposure is more common than non occupational exposure. Farmers predominated the occupational group. In males occupational exposure is common whereas in females non occupational exposure is common. 4. The duration of occupational exposure ranges from 6 months to 50 years. 5. The duration of complaints ranged from 2 weeks to 10 years. 6. About half of them did not have any seasonal variation. 7. About 12% of the patients were atopics. 8. Air borne contact dermatitis was the most common pattern observed. 9. Parthenium was the most common offending allergen. The drawbacks of this study: 1. Patch testing to common allergens only was done. 2. Photo patch testing was not done. This study shows that Parthenium is still the commonest cause of phytodermatitis in our country, causing much distress and morbidity to the patients. This multi-faceted problem needs the cooperative endeavour of our botanists, biochemists, immunologists and dermatologists. Adequate measures must be taken to eradicate this notorious weed from our country.
