Dermatitis refers to a general term for inflammation of the skin, causing various symptoms like redness, itching, dryness, or blistering. Several types of dermatitis exist, each with its own cause and presentation.
Diagnostic Criteria:
Dermatitis diagnosis often relies on a combination of factors:
- Patient History: Information about symptoms, duration, potential triggers (irritants, allergens), and past medical history is crucial.
- Physical Examination: Dermatologists will examine the affected area, noting location, distribution, and characteristics of the rash (e.g., color, pattern, scaling).
- Patch Testing: In some cases, patch testing may be used to identify allergens causing allergic contact dermatitis.
Treatment Modalities:
Treatment for dermatitis depends on the specific type and severity. Here are some common approaches:
- Emollients: Moisturizers are essential to hydrate the skin and improve barrier function.
- Corticosteroids: Topical corticosteroids reduce inflammation and itching. The potency varies depending on the severity.
- Calcineurin Inhibitors: Tacrolimus and pimecrolimus are non-steroid options used for eczema.
- Antibiotics or Antifungal Medications: These are prescribed if bacterial or fungal infections complicate dermatitis.
- Lifestyle Modifications: Identifying and avoiding triggers (irritants, allergens) is crucial for managing dermatitis.
- Bacterial Conjunctivitis: Topical antibiotic eye drops like erythromycin or gentamicin are prescribed.
- Viral Conjunctivitis: Usually resolves on its own. Artificial tears may be used for comfort.
- Allergic Conjunctivitis: Antihistamine eye drops like olopatadine or ketotifen can help manage symptoms.
- Antibiotics: Amoxicillin is the first-line antibiotic for bacterial otitis media.
- Pain relievers: Acetaminophen or ibuprofen can help manage earache.
- Decongestants: Nasal decongestants may be used in some cases to improve drainage.
- Herpes Simplex Virus (HSV): Causes cold sores (HSV-1) and genital herpes (HSV-2). Symptoms include blisters, itching, and burning.
- Varicella-Zoster Virus (VZV): Causes chickenpox (primary infection) and shingles (reactivation). Presents with itchy vesicles that progress to scabs.
- Cold Sores: Develop around the mouth as clusters of small, fluid-filled blisters.
- Genital Herpes: Causes blisters on the genitals and may be accompanied by pain, burning, and itching.
- Chickenpox: Presents with a widespread itchy rash of vesicles that progress to scabs.
- Shingles: Causes a painful, blistering rash on one side of the face or body, often following a band-like pattern.
- Impetigo: A contagious skin infection causing red, weeping sores, commonly affecting children. Treatment involves topical or oral antibiotics like mupirocin or cephalexin.
- Cellulitis: A deeper bacterial infection of the skin's deeper layers, causing redness, swelling, and pain. It requires oral antibiotics like amoxicillin-clavulanate.
- Boils and Carbuncles: Localized, pus-filled infections of hair follicles or sweat glands. Treatment involves drainage, topical antibiotics, and sometimes oral antibiotics for severe cases.
