==Physical Examination==
==Conservative Therapy==
The clinical presentation of atopic dermatitis is highly variable, depending upon the patient's age and disease activity.


===Appearance of the Patient===
*Patients with [disease name] usually appear [general appearance].
===Vital Signs===
*High-grade / low-grade fever
*[[Hypothermia]] / hyperthermia may be present
*[[Tachycardia]] with regular pulse or (ir)regularly irregular pulse
*[[Bradycardia]] with regular pulse or (ir)regularly irregular pulse
*Tachypnea / bradypnea
*Kussmal respirations may be present in _____ (advanced disease state)
*Weak/bounding pulse / pulsus alternans / paradoxical pulse / asymmetric pulse
*High/low blood pressure with normal pulse pressure / [[wide pulse pressure]] / [[narrow pulse pressure]]
===Skin===
* Skin examination of patients with usually shows:
** cardinal feature of atopic dermatitis is severe pruritus.
** An acute eczematoid eruption (with erythematous papules) appears after patients scratch their skin
** Dry skin, especially in winter, is characteristic of atopic dermatitis
* Acute atopic dermatitis:
** the skin is erythematous with papules and vesicles, and is often secondarily infected with Staphylococcus aureus
** intensely pruritic erythematous papules and vesicles with exudation and crusting
* Subacute or chronic atopic dermatitis:
** the skin is infiltrated, dry and often lichenified with scales and fissures. In severe cases the disease can develop into erythroderma
** dry, scaly, or excoriated erythematous papules
** Skin thickening from chronic scratching (lichenification) and fissuring may develop over time
**
* The clinical presentation at various ages can be described as follows:

Overview

The mainstay of treatment for atopic dermatitis depends upon the severity of the disease and is treated with combination of conservative and medical therapy. The goals of treatment include elimination of aggravating factors, skin barrier function repair, maintaining skin hydration and pharmacologic treatment of skin inflammation.

Conservative Therapy

Elimination of exacerbating factors Maintaining skin hydration Controlling pruritus
  • Avoid trigger factors such as low humidity, overheating of skin
  • Treating stress and anxiety
  • Avoid exposure to solvents and detergents
  • Treat skin infections such as Staphylococcus aureus and herpes simplex
  • Emollients and moisturizers
    • Thick creams, ointments (eg, petroleum jelly) with low/zero water content
    • Immediately after 5-minute, lukewarm baths BID
  • Bathing practices
    • Warm soaking baths or showers using mild or soap-free cleansers
  • Conservative
    • Tepid baths
    • Wet dressings (wet wraps)
    • Moisturizers containing anti-pruritic ingredients such as phenol, menthol, and camphor

Medical Therapy

  • Pharmacologic medical therapies for atopic dermatitis can be classified according to the several severity scales( (i.e SCORAD index, the eczema area and severity index [EASI], and the patient-oriented eczema measure [POEM]) which includes characteristics of the rash, questions about itch, sleep, impact on daily activities, and persistence of disease.

  • Viral infections:
    • Herpes simplex:
      • Acyclovir 200 or 400 mg PO five times daily
      • Famciclovir 750 mg BID for one day or 1500 mg as a single dose
    • molluscum contagiosum :
      • cryotherapy, curettage, cantharidin, and podophyllotoxin as first-line therapeutic options
  • Fungal infections:
    • Dermatophyte infections- topical or oral antifungals

Controlling pruritus:

Chronic inflammatory skin diseases

  • Contact (allergic, irritant)
  • Seborrhoeic dermatitis
    • onset during the 1st days or weeks of life, absence of pruritus, and presence of greasy scaling on a yellow-red base
    • Involvement of the top of the scalp (cradle cap), axilla, and diaper area makes it more likely the patient has seborrheic dermatitis, vs excoriated dermatitis involving the extensor surfaces, face, and trunk favour AE.
