...short, there was a scary layer of cultural ignorance underlying Pacheco's letter. The kind of cultural ignorance about his own American society that leads him to talk in almost jocular terms about the white supremacist and anti-Semitic prone World Church of the Creator-a core Christian identity group-as if it were just some silly old bunch or "group of horrible people." -Martin Kilson, Frank G.

First-degree burns, which are the least dangerous because they involve only the outer, epidermal, layer of the skin, usually do not require hospitalization. Thin as a sheet of paper, the epidermis consists of about five layers of cells. The cells in the deepest layers constantly reproduce, pushing older layers to the surface, where they slough off after two weeks or so. Thus while first-degree burns appear red and swollen and are painful to the touch, they usually heal on their...
Second- and third-degree burns, the kind treated by the New York team, call for much more care and, often, extended hospital stays. Penetrating below the epidermis, second-degree burns reach into the upper layer of the dermis, a thin layer of cells 1 to 3 mm thick that contains blood vessels, nerves, hair follicles and sweat glands. This upper portion can slowly regenerate and heal if damaged. But if the burn is third degree and destroys the dermis down to fat and muscle, skin grafts are needed for effective healing...

"I know I've reached healthy skin if there's bleeding," he says. After a few thin layers have been removed, blood begins to ooze. While Polynice mops it up, Himel continues to peel away at dead skin until he reaches the fat and muscle layer underneath...

The traditional cure used by healers is leaves of Centella asiatica, a ground-hugging vine, which Salome chews into a poultice, smears on a cloth and then places as a compress on the afflicted eye for three consecutive nights...
