Background

  • Also know as atopic eczema
  • A chronic type of inflammatory skin disease affecting many children and adults
  • Occasionally accompanied by asthma and/or hay fever. Patients develop a cutaneous hyperreactivity to environmental triggers.
  • Cause is not known, but believed to be due to an interaction between susceptibility genes, the environment, defective skin barrier function, and immunologic responses.

Clinical Features

Atopic dermatitits.jpg
  • Atopic personal or family history, worse in winter, dry weather
  • Erythema, crusts, fissures, pruritis, excoriations, lichenification

Infantile

  • blisters, crusts, exfoliations
  • Face, scalp, extremities
  • 1st few months of life, resolving by age 2
  • Differentiate from impetigo (which may occur alongside)

Adults

  • Dryness, thickening in AC and popliteal fossa, neck

Differential Diagnosis

Neonatal Rashes

Evaluation

  • Clinical diagnosis
    • Dry skin, erythematous papular lesions
    • Face most commonly involved; nose and diaper areas spared

Neonatal atopic dermatitis vs. seborrhoeic dermatitis

Category Neonatal atopic dermatitis Neonatal seborrhoeic dermatitis
Presentation 1-2 months 2-6 months
Puritic (fussiness) Yes No

Management

  • Identify and eliminate triggers
  • Reduce drying of skin
  • Liberal application of emollients (vaseline)
  • Triamcinolone, hydrocortisone, or betamethasone
  • Avoid fluoridinated steroids to the face
  • Consider doxepin for recalcitrant pruritis[1][2]
    • 25-50mg PO qhs
    • Or topical doxepin cream 5% QID
