the rule of nines
regarding burns divides the body into percentages that are, for the most part, multiples of nine: the head and neck equal 9%, each upper limb 9%, each lower limb 18%, the front and back of the torso 36%, and the genital area 1% (Fig. 4.8). Fig. 4.9 illustrates the different degrees of burns.
Second-degree burn (partial-thickness burn):
A burn in which only the first and second layers of the skin (the epidermis and part of the dermis) are affected. If the burn extends to the papillary level, it is classified as a superficial partial-thickness burn. If it extends farther, to the reticular layer, it is classified as a deep partial-thickness burn. This type of burn is characterized by redness, blisters, and pain, with possible scar development.
tinea pides
is a fungal infection that usually begins between the toes. It commonly occurs in people whose feet have become very sweaty while confined within tightfitting shoes
Third-degree burn (full-thickness burn):
A burn that damages the epidermis, dermis, and subcutaneous tissue. Pain is not present because the nerve endings in the skin have been destroyed. The skin may appear deep red, pale gray, brown, or black. Scar formation is likely.
