Study Notes
Dermatological Conditions and Treatments Overview
- Lesion classification: bulla, wheals, secondary lesions (scales, crust, erosion, ulcer, atrophy, scars)
- Diagnostic tests include biopsy, potassium hydroxide, skin scrappings, gram staining, fungal and bacterial cultures, Tzanack test, Wood’s light, patch test, dark field/blood test
- Neoplasms assessment criteria: A (asymmetry), B (border), C (color), D (diameter), E (evolution)
- Basal cell carcinoma: slow-growing, locally invasive, pearly or waxy, central ulceration in later stages
- Squamous cell carcinoma: second most common, originates from keratinocytes, tendency to metastasize
- Basic treatment goals: maintain skin barrier, skin cleansing, moisturization, topical formulations, wet dressings
- Eczematous conditions progression: acute and chronic inflammation, differentials, and possible etiologies
- Fungal infections: tinea (dermatophyte) examples and treatment, candida infection causes and examples
- Topical and systemic agents for treating tinea infections
- Candida albicans exacerbating conditions and examples of infections
- Treatment for candida infections
- OTC treatment for tinea infections: Selsum Blue
