Contact Dermatitis (CD) is an altered state of skin reactivity induced by exposure to an external agent. According to the mechanism of elicitation, the following types of contact reactions may be distinguished: Allergic Contact Dermatitis (ACD), Irritant Contact Dermatitis (ICD), Phototoxic and Photo Allergic Contact Dermatitis and Immediate Type Contact Reactions or Immune Contact Urticaria. ACD is a delayed-type hypersensitivity reaction that is elicited when the skin comes in contact with a chemical to which an individual has previously been sensitised. Patch testing remains the gold standard for diagnosing ACD. This study focuses on identifying the allergens causing ACD of hands and feet. METHODStudy was conducted in Osmania General Hospital, Hyderabad, over a period of 12 months' duration. Patients suspected to have contact dermatitis were subjected to patch testing. Based on the history, clinical signs and symptoms, a total of 50 patients were shortlisted in 12 months' duration. RESULTOur study showed that the most common allergen showing patch test positivity in both males and females were metals like chromates followed by cosmetics and others. Patients showed significant improvement in their dermatitis after avoidance of the offending agent. CONCLUSIONPatch test is the method of choice and the "gold standard" in the detection of contact allergy and allergic contact dermatitis.

“…Grooves at the chamber site were indicative of good occlusive effect. Second reading was taken on day 4 Where reactions were doubtful even on day 4, a further 'late' reading was taken 7-10 days later. Those Positive (+) 48 hours and Negative (-) 96 hours were not considered as positive.…”

“…Allergic contact dermatitis (ACD) is a chronic inflammatory disorder. The prevalence of ACD varies in different parts of the world, 1 - 3 with prevalence rates of 1.5-5.4% in the US, and up to 28% in Spain. 4 , 5 Several factors such as the type of the allergen, duration of exposure, region, age, gender, and race have been implicated in the induction of ACD and may contribute to differences in prevalence rates.…”

Objectives:To detect common skin-sensitizing agents among patients experiencing allergic contact dermatitis (ACD).Methods:This was a retrospective study of 152 patients with clinically suspected ACD who underwent patch testing in an allergy clinic at King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia between January 2012 and February 2015. Of these patients, only 74 (48%) patients reacted to one or more contact allergens. This group of patients included 58 (78.4%) women and 16 (21.6%) men (mean age: 37.8±13.8 years). Patch testing was performed using the thin-layer rapid-use epicutaneous patch test panels.Results:Nickel sulfate was the most common sensitizing agent, with 26 (35.1%) patients yielding a positive result; followed by p-phenylenediamine in 17 (22.9%), butyl-tetra-phenol formaldehyde in 12 (16.2%), gold sodium thiosulfate in 10 (13.5%), and thimerosal in 6 (8.1%) patients. Nickel reactivity was significantly higher among women (41.4%) than among men (12.5%) (p<0.0001). Similarly, gold reactivity among women (15.5%) was also higher than among men (6.2%) (p≤0.02).Conclusion:The high level of skin sensitization due to nickel, PPD, and gold in patients with ACD emphasizes the need for measures to decrease exposure to these sensitizing agents.

“…Recent studies suggest that allergic contact dermatitis remains more common in adults than in children (Kwangsukstith & Maibach, 1995) affecting approximately 10% of the adult population (Marks, 1997) and accounting for just over 4% of all dermatologic consultations (Mendenhall et al, 1973). Though the condition is increasingly being recognized in the pediatric population, most epidemiologic studies have been completed retrospectively and investigate the occurrence of positive patch tests in symptomatic patients only.…”
