| Psorisis is a chrnoic non contagious. Skin cells reproduce rapdily & also die quick but do not fall off causing patches(red). Caused by genetics, injury, or emotional stress. | Amevive(alefacept)-im iv remicade(infliximab)-iv Enbrel(etanercept)sc inj raptiva(efalizumab) sc inj q wk oral elide(pimcrolimus) 20-30 mg po bid |
| shingles, herpes, chicken pox, cold sores, & warts caused by the same virus: epsteinbarr virus. | treated by antivirals (acloyvir) zoviraxorally, top., or iv |

| 1st degree2nd degree | 1st- limited damage to epidermis (red, pain) superficial burn.2nd-dam. 2 epidermis & dermis(red blister mild-mod. edema pain. mod burn) |
| 3rd degree4th degree | 3rd- destruction of epidermis, dermis, & subcutaneous tiss. (leathery, dry white, blk or cherry, no blistering, critical burn)4th- total destruction of all skin tissue , muscle, tendons, ligaments, and bones. critical to fatal in natural. |
