Definition : skin inflammation (epidermodermitis) subjective : itchy objective : polymorph
CATCH BASKET TERM* Eczema :• UNITARIS ( Europe ) : Eczema & dermatitis synonim • DUALISTIS ( United State ) : Eczema & dermatitis not synonim
![Page 3: dermatitis kuliah S-0 usb.ppt](https://reader036.fdocuments.us/reader036/viewer/2022062310/5695d0361a28ab9b029176e5/html5/thumbnails/3.jpg)
Dermatitis consist of several stages :• I Erythema - edematous• II Vesico - bullous• III Madidans (wet)• IV Desquamation (crust & dry)
CLASSIFICATION :
1. Etiology
• Exogen : contact dermatitis, dermatitis caused by drug
• Endogen : atopic dermatitis, neurodermatitis, stasis dermatitis

2. Form :
numular dermatitis
3. Course of the disease :
• Acute : several days - 1 week
• Subacute
• Chronic : 1,5 months or more
![Page 5: dermatitis kuliah S-0 usb.ppt](https://reader036.fdocuments.us/reader036/viewer/2022062310/5695d0361a28ab9b029176e5/html5/thumbnails/5.jpg)
caused by exogenous material
• 2 forms :
* Irritant contact dermatitis (ICD)
* Allergic contact dermatitis (ACD)
IRRITANT CONTACT DERMATITIS
• Etiology : primary irritant contact• Onset : first contact• Subjective : burning• Lesion : more severe than ACD, circumscribed,
oedema erythematous acute, blister • Contactant ( - ) : heal rapidly
CONTACT DERMATITIS

Irritant Contact Dermatitis
Divided based on the type of irritant :
* Strong irritant : strong acid and alkali agent
rapid and more severe dermatitis (toxic contact dermatitis)* Weak irritant : soap, detergent, dye (hair dye, shoes polish) chronic, etiologic agent depend on concentration and skin thickness

ALLERGIC CONTACT DERMATITIS
• Etiology : sensitizer
• Onset : repeatly contacts
• Subject : allergic patient
• Subjective : itchy
• Lesion : uncircumsribed
• Contactant (-) : exist / increase

ALLERGIC CONTACT DERMATITIS
* Occurred only at certain patient* Hypersensitivity type IV* Allergen :
* Metal : jewellery, watch, glasses* Cosmetic
* Diagnosis : History : burning / itchy after contact • Clinical manifestation : * More toxic * Localization depend on contact location * Subjective : polymorph

Supporting examination:PATCH TEST
* For allergic contact dermatitis patient
• Suspected agent patch at volar or interscapular region
covered by impermeable material
* Read after 24 - 48 hours
* Criteria :# Erythema +# Erythema + oedema + +# Vesicle + + +# Confluent vesicles + + + +# Necrosis + + + + +

Patch test conditions• Skin lesion has already cleared • During occlusion do not exposure to water and sweating• 3 days before : do not consume any drugs, esp antihistamin and corticosteroid
TREATMENT OF CONTACT DERMATITIS* Stop contact with causative agent* Drugs :
*Topical depend on lesion : Wet dressing Dry corticosteroid ointment Subacute cream *Systemic antihistamine
if severe corticosteroid

ATOPIC DERMATITIS
* Atopic term from atopy• ATOPY : a group of hereditary disease with hypersensitivity allergic symptoms
* asthma* hay fever* allergic rhinitis* hives* drug/food allergic
* Only occurred at certain people
![Page 20: dermatitis kuliah S-0 usb.ppt](https://reader036.fdocuments.us/reader036/viewer/2022062310/5695d0361a28ab9b029176e5/html5/thumbnails/20.jpg)
CRITERIAS OF ATOPIC DERMATITIS
• Skin inflammation with atopy base in patient or family who has symptoms, i.e erythema, oedema and scales
* Synonims : Eczema flexurarum Disseminated lichen chronicum simplex Prurigo diasthetique
Wise & Sulzberger ( 1923 ) :
![Page 21: dermatitis kuliah S-0 usb.ppt](https://reader036.fdocuments.us/reader036/viewer/2022062310/5695d0361a28ab9b029176e5/html5/thumbnails/21.jpg)
* Scratch/ trauma
* Allergen, air pollution, wool, fabrics
* Physical stress
* Temperature changes ( climates changes )
* Sweat retention
* etc.
* Etiology : poorly understood, multifactorial
* Genetic
* Organ sensitivity (level of itchy sensation > lower )
![Page 22: dermatitis kuliah S-0 usb.ppt](https://reader036.fdocuments.us/reader036/viewer/2022062310/5695d0361a28ab9b029176e5/html5/thumbnails/22.jpg)
D I A G N O S I S
* History : chronic recurrent (remission)
* Symptom : divide into 3 phases (Sulzberger) based on age :

III. Adolescent + adulthood (> 13 years)
* Primary symptoms :
severe itching, caused by scratching skin lesions :
erythema, edema, vesicles, crusts, lichenification
sign of chronic skin disease caused by longtime scratching
