Dermatitis, Eczematous
Conditions
Brief summary
48-hour application of metal allergen patches to test for potential allergic responses.
Detailed description
A 48-hour application (approximate) of investigational allergen panels, excipient controls and corresponding reference allergens will be applied to the skin of human subjects to test for potential positive allergic responses. Test sites will be evaluated at 3-4, 7-8, 10-14 and 19-23 days after application. Ascending allergen dosages will be randomized within each panel into three different configurations which will be randomly assigned to subjects as they enter the study. The investigators and subjects will be aware of the allergens and the patch test doses but will not be aware of the location of individual allergens within each panel.

Eligibility
Inclusion criteria

Determination of positive or negative test response for each allergen dose was assessed by the investigator following the final visit. |

| Tape Irritation | Visit 2 (day 2), visit 3 (day 3-4), visit 4 (day 7-8) visit 5 (day 10-14), visit 6 (day 19-23) with overall assessment by the Investigator following visit 6 | Tape irritation was measured according to the following scale: None- No irritation, Weak- Faint to definite pink erythema, Moderate- Moderate erythema, definite redness, Strong- Severe erythema, very intense redness. Following visit 6, the Investigators rated tape irritation based on the overall trend observed at visits 2-6. Irritation at visit 2 that resolved by visit 3 was considered none. Skin under occlusion from an adhesive material would be expected to have minimal irritation shortly after the panel is removed. Irritation that persisted or increased in severity beyond visit 3 but resolved by the following visit would have been rated as irritant. An allergic response was considered if irritation persisted beyond visit 3, increased in severity and had symptoms consistent with criteria used to score positive skin reactions according to standard patch testing guidelines established by the International Contact Dermatitis Research Group. |

Chip Irritation
Chip irritation was measured according to the following scale: None- No irritation, Weak- Faint to definite pink erythema, Moderate- Moderate erythema, definite redness, Strong- Severe erythema, very intense redness. Following visit 6, the Investigators rated Chip irritation based on the overall trend observed at visits 2-6. Irritation at visit 2 that resolved by visit 3 was considered none. Skin under occlusion from an adhesive material would be expected to have minimal irritation shortly after the panel is removed. Irritation that persisted or increased in severity beyond visit 3 but resolved by the following visit would have been rated as irritant. An allergic response was considered if irritation persisted beyond visit 3, increased in severity and had symptoms consistent with criteria used to score positive skin reactions according to standard patch testing guidelines established by the International Contact Dermatitis Research Group.
Time frame: Visit 2 (day 2), visit 3 (day 3-4), visit 4 (day 7-8) visit 5 (day 10-14), visit 6 (day 19-23) with overall assessment by the Investigator following visit 6

Number of Subjects With Panel Adhesion
Panel Adhesion was measured at Visit 2 (day 2) prior to panel removal according to the following scale: Excellent- Skin contact good; all tape edges adherent; all allergens in contact with the skin, Good- Skin contact acceptable; some tape edges lifting; all allergens in contact with the skin, Poor- Little to no skin contact with panel; one or more allergens not in contact with the skin, Detached- Panel completely off the skin; none of the allergens in contact with the skin
Time frame: Day 2, visit 2 prior to panel removal

Tape Irritation
Tape irritation was measured according to the following scale: None- No irritation, Weak- Faint to definite pink erythema, Moderate- Moderate erythema, definite redness, Strong- Severe erythema, very intense redness. Following visit 6, the Investigators rated tape irritation based on the overall trend observed at visits 2-6. Irritation at visit 2 that resolved by visit 3 was considered none. Skin under occlusion from an adhesive material would be expected to have minimal irritation shortly after the panel is removed. Irritation that persisted or increased in severity beyond visit 3 but resolved by the following visit would have been rated as irritant. An allergic response was considered if irritation persisted beyond visit 3, increased in severity and had symptoms consistent with criteria used to score positive skin reactions according to standard patch testing guidelines established by the International Contact Dermatitis Research Group.
Time frame: Visit 2 (day 2), visit 3 (day 3-4), visit 4 (day 7-8) visit 5 (day 10-14), visit 6 (day 19-23) with overall assessment by the Investigator following visit 6
