            Contact Dermititis

            Published by Dr Josรฉ Costa at 27/11/2021

            Parentsย have asked me if a diagnosis of aย food allergyย can be made by placing the food on theย skin.โฃ

            The answer is, not always.โฃ
            Why is that?โฃ

            Not all concentrations of the allergen can lead to a reaction.โฃ

            • Some reactions might be due to a ๐˜Š๐˜ฐ๐˜ฏ๐˜ต๐˜ข๐˜ค๐˜ต ๐˜‹๐˜ฆ๐˜ณ๐˜ฎ๐˜ข๐˜ต๐˜ช๐˜ต๐˜ช๐˜ด.โฃ

            ย 

            ๐‚๐จ๐ง๐ญ๐š๐œ๐ญ ๐ƒ๐ž๐ซ๐ฆ๐š๐ญ๐ข๐ญ๐ข๐ฌย happens when a substance gets in contact with the skin, causing a localised reaction.โฃ

            ย 

            It can be eitherย ๐˜ช๐˜ณ๐˜ณ๐˜ช๐˜ต๐˜ข๐˜ฏ๐˜ตย (80% of reactions) orย ๐˜ข๐˜ญ๐˜ญ๐˜ฆ๐˜ณ๐˜จ๐˜ช๐˜คย (20% of reactions), leading to different reactions.โฃ

            ย 

            It affects people that deal with the substances frequently, though it can happen to anyone.โฃ

            • Most commonly, it affects people working in theย ๐˜ค๐˜ฉ๐˜ฆ๐˜ฎ๐˜ช๐˜ค๐˜ข๐˜ญ,ย ๐˜ฑ๐˜ฉ๐˜ข๐˜ณ๐˜ฎ๐˜ข๐˜ค๐˜ฆ๐˜ถ๐˜ต๐˜ช๐˜ค๐˜ข๐˜ญย orย ๐˜ฃ๐˜ฆ๐˜ข๐˜ถ๐˜ต๐˜บ ๐˜ช๐˜ฏ๐˜ฅ๐˜ถ๐˜ด๐˜ต๐˜ณ๐˜บ.
            • ๐˜”๐˜ฆ๐˜ค๐˜ฉ๐˜ข๐˜ฏ๐˜ช๐˜ค๐˜ดย andย ๐˜ฉ๐˜ฆ๐˜ข๐˜ญ๐˜ต๐˜ฉ๐˜ค๐˜ข๐˜ณ๐˜ฆ ๐˜ธ๐˜ฐ๐˜ณ๐˜ฌ๐˜ฆ๐˜ณ๐˜ดย can also be affected.โฃ
            Irritant Contact Dermatitis
            Allergic Contact Dermatitis

            Treatment starts with avoidance of contact with the substance causing the reaction.โฃ
            Following this, the creams used are very similar to the ones used inย eczema.โฃ
            It is not frequent the need for oral or intravenous medication.โฃ

            How to make a diagnosis?โฃ

            • It is fairly easy, as there is a good association between the contact and the onset of the reaction.โฃ
            • In some cases, when there is a mix of chemicals,ย patch testingย can be used (I will speak about this in another post).โฃ

            There is also a difference in signs.โฃ

            • ๐ˆ๐ซ๐ซ๐ข๐ญ๐š๐ง๐ญ:โฃ
            1. Blistersโฃ
            2. Dry skin leads to crackingโฃ
            3. Cracking leads to sores and crustsโฃ Swellingโฃ

            ย 

            • ๐€๐ฅ๐ฅ๐ž๐ซ๐ ๐ข๐œ:โฃ
            1. Hivesโฃ
            2. Itchingโฃ
            3. Red skinโฃ
            4. Dry and flaking skinโฃ
            5. Swelling, especially if affecting mucosasโฃ

            ย 

            Nickel can give irritant andย allergic contact dermatitis.
