Prevention of Pityriasis rosea
Pityriasis rosea is a common, self-limited inflammatory skin condition whose exact cause is not fully established. Because the underlying trigger is not completely defined, there is no proven method that can prevent every case. In practical terms, prevention means reducing the likelihood that the biological events associated with the condition will be set in motion,…

Prevention of Pemphigus vulgaris
Pemphigus vulgaris is an autoimmune blistering disease in which the immune system produces antibodies that target proteins needed for the normal adhesion of skin and mucosal cells. The result is loss of cell-to-cell attachment, a process called acantholysis, which leads to fragile blisters and erosions. Because the disorder arises from an abnormal immune response rather…

Prevention of Pediculosis
Pediculosis, the infestation of hair or body with lice, can often be prevented in part, but not always eliminated entirely through environmental measures alone. The reason is biological: lice are parasites that move from one human host to another, attach to hair or clothing, and feed on blood. Prevention therefore depends on reducing opportunities for…

Prevention of Onychomycosis
Onychomycosis, a fungal infection of the nails, can often be prevented in the sense that the conditions that allow fungal organisms to colonize the nail can be reduced. Complete prevention is not always possible because exposure to fungi is common and some people have biological or medical factors that make infection more likely. For that…

Prevention of Morphea
Morphea, also called localized scleroderma, is an inflammatory skin disorder in which the immune system and connective tissue behave abnormally in a limited area of the body. The condition leads to excess collagen deposition, thickening of the skin, and in some cases involvement of deeper tissues such as fat, fascia, muscle, or bone. Because the…

Prevention of Molluscum contagiosum
Molluscum contagiosum is a skin infection caused by a poxvirus that replicates in the outer layer of the skin. It is usually spread by direct skin contact, contact with contaminated objects, or by transferring virus from one skin site to another through scratching or shaving. Because the virus depends on close contact with the skin…
