The objectives of the two types of research and their underlying philosophical assumptions are simply different. However, as discussed in the section on âphilosophies guiding researchâ, this does not mean that the two approaches cannot be used in the same study.
Impetigo is a skin infection, caused by Staphylococcus aureus, Streptococcus pyogenes, or both, that leads to the formation of scabby, yellow-crusted sores and, sometimes, small blisters filled with yellow fluid. Ecthyma is a form of impetigo that causes sores deeper in the skin. Impetigo is common. It affects mostly children. Impetigo can occur anywhere on the body but most commonly occurs on the face, arms, and legs. The blisters that may form (bullous impetigo) vary in size and can last for days to weeks.
The impetigo blisters eventually break open, revealing red, oozing skin. The skin weeps fluid. A yellow-brown crust forms over the skin, and the infection spreads to other areas. Itching is common and scratching the infected area and touching another part of the body can further spread the infection. Impetigo is most common in childhood, and in infants impetigo can spread and infect the entire body. Other symptoms that accompany impetigo include fever and swollen glands.
