Bacterial Diseases of the Skin

The document discussed various bacterial skin diseases, focusing on their clinical presentations and treatments. Nonbullous impetigo was identified as the most common pediatric skin infection, characterized by lesions that form a yellow crust. Bullous impetigo, less common and affecting infants, involved larger vesicles and required systemic antibiotics if infections spread. Ecthyma resulted from untreated impetigo, necessitating systemic antibiotics. Folliculitis, an infection within hair follicles, could progress to furuncles or carbuncles, requiring surgical drainage if topical treatments failed. Paronychia and felons, common hand infections, often needed surgical drainage. Cellulitis, a severe skin and subcutaneous tissue infection, required systemic antibiotics and sometimes surgical intervention.
