Introduction

Eczema = Dermatitis
![Page 5: ECZEMA. Introduction Case Scenarios Conclusions Introduction](https://reader036.vdocuments.us/reader036/viewer/2022062404/5516109855034694308b52db/html5/thumbnails/5.jpg)
Effect on Quality of Life(Burden of Disability)
• 10-15% children suffer from atopic dermatitis
• Asteototic dermatitis is becoming more and more common in the elderly
• Hand dermatitis is a major cause of absence from work
![Page 6: ECZEMA. Introduction Case Scenarios Conclusions Introduction](https://reader036.vdocuments.us/reader036/viewer/2022062404/5516109855034694308b52db/html5/thumbnails/6.jpg)
• Basic assessment and treatment
![Page 7: ECZEMA. Introduction Case Scenarios Conclusions Introduction](https://reader036.vdocuments.us/reader036/viewer/2022062404/5516109855034694308b52db/html5/thumbnails/7.jpg)
Case 1
• 6 months old child• Onset of problems at
age 2 months• Formula fed child-
several changes in milk tried
• “None of the ointments work”
![Page 8: ECZEMA. Introduction Case Scenarios Conclusions Introduction](https://reader036.vdocuments.us/reader036/viewer/2022062404/5516109855034694308b52db/html5/thumbnails/8.jpg)
• Sleeping poorly• Allergy tests?
![Page 9: ECZEMA. Introduction Case Scenarios Conclusions Introduction](https://reader036.vdocuments.us/reader036/viewer/2022062404/5516109855034694308b52db/html5/thumbnails/9.jpg)
Basic Management of Atopic Dermatitis
• Explanation – expectations of treatment
• Emollients
• Topical Corticosteroids
![Page 10: ECZEMA. Introduction Case Scenarios Conclusions Introduction](https://reader036.vdocuments.us/reader036/viewer/2022062404/5516109855034694308b52db/html5/thumbnails/10.jpg)
Explanation
• Incredibly common
• Cause unknown – NOT allergy
• Self-limiting in most cases (eventually)
• Waxing and waning natural history
![Page 11: ECZEMA. Introduction Case Scenarios Conclusions Introduction](https://reader036.vdocuments.us/reader036/viewer/2022062404/5516109855034694308b52db/html5/thumbnails/11.jpg)
Emollients
• Bath
• General
• No limit to their use
![Page 12: ECZEMA. Introduction Case Scenarios Conclusions Introduction](https://reader036.vdocuments.us/reader036/viewer/2022062404/5516109855034694308b52db/html5/thumbnails/12.jpg)
![Page 13: ECZEMA. Introduction Case Scenarios Conclusions Introduction](https://reader036.vdocuments.us/reader036/viewer/2022062404/5516109855034694308b52db/html5/thumbnails/13.jpg)
Topical Corticosteroids
• Mainstay of treatment
• Not dangerous if properly used
• Most “steroid phobias” allayed by explanation
• Awareness of different strengths
![Page 14: ECZEMA. Introduction Case Scenarios Conclusions Introduction](https://reader036.vdocuments.us/reader036/viewer/2022062404/5516109855034694308b52db/html5/thumbnails/14.jpg)
Package of Care
• Time
• Explain
• Prescribe a package of emollient(s) and topical steroid(s)
• Empower the parents to alter strengths of corticosteroids depending on clinical severity
![Page 15: ECZEMA. Introduction Case Scenarios Conclusions Introduction](https://reader036.vdocuments.us/reader036/viewer/2022062404/5516109855034694308b52db/html5/thumbnails/15.jpg)
Role of Nursing Colleagues
• Ideal disease for follow-up by practice nurses and health visitors
• Offer support through chronic disease
• Easy access for flares of disease
• Support from specialist dermatology nurses in secondary care
![Page 16: ECZEMA. Introduction Case Scenarios Conclusions Introduction](https://reader036.vdocuments.us/reader036/viewer/2022062404/5516109855034694308b52db/html5/thumbnails/16.jpg)
What about Infection?
• Staphylococcus aureus on 100% of skin lesions
• But antibiotics don’t cure atopic dermatitis
• But some cases improve when either topical or systemic antibiotics added
![Page 17: ECZEMA. Introduction Case Scenarios Conclusions Introduction](https://reader036.vdocuments.us/reader036/viewer/2022062404/5516109855034694308b52db/html5/thumbnails/17.jpg)

Eczema Herpeticum
• Unwell patient• Severe pain• Typical umbilicated,
coalescing papules• Herpes simplex virus
(usually type 1)• Urgent hospital
admission
![Page 19: ECZEMA. Introduction Case Scenarios Conclusions Introduction](https://reader036.vdocuments.us/reader036/viewer/2022062404/5516109855034694308b52db/html5/thumbnails/19.jpg)

What to Try if Adequate control NOT Achieved
• Concordance (social issues)
• Infection
• “Pulse” of stronger topical corticosteroid
• Bandaging
• Referral
![Page 21: ECZEMA. Introduction Case Scenarios Conclusions Introduction](https://reader036.vdocuments.us/reader036/viewer/2022062404/5516109855034694308b52db/html5/thumbnails/21.jpg)

Pathogenesis
• Dryness and suppleness = state of hydration of Stratum corneum
• State of hydration of stratum corneum dependant on rate of migration of water through stratum corneum and rate of evaporation from its surface
• Natural level of skin lipids decreases as age increases
![Page 24: ECZEMA. Introduction Case Scenarios Conclusions Introduction](https://reader036.vdocuments.us/reader036/viewer/2022062404/5516109855034694308b52db/html5/thumbnails/24.jpg)
Management
• Is the patient clinically or sub-clinically dehydrated?
• Is the environment too dry?
• Is the skin being degreased too frequently or too harshly?
![Page 25: ECZEMA. Introduction Case Scenarios Conclusions Introduction](https://reader036.vdocuments.us/reader036/viewer/2022062404/5516109855034694308b52db/html5/thumbnails/25.jpg)
• Emollient
• Topical corticosteroid – dip in and out after initial pulse
![Page 26: ECZEMA. Introduction Case Scenarios Conclusions Introduction](https://reader036.vdocuments.us/reader036/viewer/2022062404/5516109855034694308b52db/html5/thumbnails/26.jpg)
